xv U Executive Summary El The Public and Personal Health section of the Department of Health commissioned Health Research and Analytical Services, Department of Health, to conduct research investigating Part II of the Smokefree Environments Act, 1990. The report is divided U into three distinct sections. Section one reviews the literature adolescent smoking behaviour and knowledge and U details the strategies that have been used to prevent adolescents from starting smoking or smoking cessation programmes directed at adolescent smokers. U Section two reports the findings of a smoking behaviour and knowledge survey conducted with 890 New Zealand adolescents between 12 and 17 years of age. The results update a similar national survey of New Zealand adolescents conducted by the National Research Bureau in 1991 (National Research Bureau, 1991). U Section three focuses on Part II of The Smoke Free Environments Act (1990). The findings of a national survey of 1017 retailers support, understanding, knowledge and U information requirements related to Part II of The Smoke Free Environments Act (1990) are reported. U Aims and purposes of the research
• Literature review U The alms of the literature review were with respect to the following five topics: U (i) To describe and review the smoking behaviours and habits of adolescents
(ii) To describe and review tobacco promotion and adolescent smoking U (iii) To review proven health promotion strategies U (iv) To examine contemporary adolescent lifestyles and their impact on smoking behaviours and habits within a sociological context U (v) To describe and review the sale of cigarettes to "minors" U • Student smoking Survey The overall aim of this survey was to provide updated information on the nature and U extent of smoking behaviour and beliefs in a sample of 12-17 year old New Zealand school children. The specific aims were: 9 • To determine the incidence ofpast and present smoking behaviour examined by age, gender, ethnicity and place of domicile. U • To examine the awareness of advertising and brand promotion of tobacco products and their association through sponsorship with sporting and non- sporting events in a random sample of 12-17 year old school children. U U xvi 0 • Amongst current smokers, to describe the number smoked per week, sources of cigarettes, and brand(s) smoked and why.
• Retailer survey
• To determine what additional information and support retailers need to comply with the Smoke-free Environments Act (1990), especially Part Ii of the Act.
Methods
• Literature review
The main sources of information included:
• an on-line computer search of databases for relevant books, articles, reports and newspaper clippings,
• published and unpublished reports and documents provided by key informants, and
• recent journals were scanned for relevant articles.
• Student smoking Survey
The student smoking survey was conducted with a randomly selected sample of secondary school pupils from 14 high schools in five areas. Seven of the schools were located in main urban centres, four in provincial centres and three in smaller semi rural towns. Sampling procedures were weighted to ensure that a high level of Maori and Pacific Island representation was sampled.
The survey was a self-administered questionnaire completed at school. Demographic information sought included: age, gender, ethnicity and place of residence.
The final sample size was 890 students ranging in age from 12 to 17 years. A high response rate of 89 percent was obtained, (890/995).
• Retailer survey
The yellow pages of 18 Telecom telephone directories were used to obtain the population of retailers sampled. The headings scanned were "dairies" and "Grocers and Supermarkets".
The final sample size used in the analysis was 1017, which represented a response rate of 39 percent. That is, approximately four in ten dairy, grocery, supermarket, etc. retailers listed in the yellow pages of the telephone books completed and returned the survey. This is lower than expected, although there was no follow-up of non - respondents.
xvii Results
• Literature review
Eighty-five percent of lung cancer deaths and 30% of all cancer deaths are attributable to smoking.
Maori men and women have one of the highest recorded incidences of lung cancer in the world.
The lung cancer rate in New Zealand women tripled between 1964 and 1986 and is still rising.
Smoking is a major public health problem in New Zealand. Prevalence
Overseas surveys have observed a significant decline in the smoking prevalence of adults, accompanied by a somewhat less striking and more recent decline in the smoking prevalence of adolescents.
Ethnic differences in smoking have also been identified in both the U.S. and Australia.
One in four adult New Zealanders in 1990 were smokers with an average consumption of 12 cigarettes a day.
In New Zealand, cigarette consumption has declined since 1983 but this decline has been more marked for men then for women.
For Maori women there has been no clear evidence that smoking rates are falling: 58.5% in 1981; 62.0% in 1989; 57.2% in 1990. Approximately 50 New Zealand children take up smoking every day.
A survey of 1600 New Zealand teenagers aged between 10-15 years in 1989 and 1991 showed 4% in 1989 (5% in 1989) teenagers were regular smokers, a further 25% said that they had experimented with cigarettes to some degree, most only trying them once.
Adolescent smoking uptake and maintenance has been associated with a number of factors which can be grouped under eight main headings: • Peer group smoking behaviour
U Family smoking behaviour
U Knowledge and attitudes about smoking
U Demographics
U School related factors
xviii Personal factors Advertising Availability
Smoking prevention
The central aim of public policy in the control of cigarette smoking should be to minimize the health damage of cigarette smoking, with a secondary aim being to minimize the economic dislocation resulting from the achievement of this health goal. Intervention strategies focus on either changing the individual or changing the environment in which the individual operates.
Restricting access to tobacco
One solution to the problem of adolescent smoking is to restrict children s access to cigarettes thereby reducing consumption of the product and, ultimately, damage to health.
Banning cigarette advertising
The extent to which cigarette advertising contributes to increases in smoking has been hotly debated by public health professionals and the tobacco industry. Research suggests that there are significant relationships between measures of advertising and smoking.
Student smoking Survey
Seventy percent of both males and females in the sample had smoked at least one cigarette.
Of the 13 year olds, 46% of the females and 38% of the male had tried smoking. For both sexes 80% of 15, 16, and 17 year olds had tried smoking. Three times as many females in comparison with males continued to smoke after their first cigarette. In the 16-17 year age group, 39% of the females and 24% of the males had smoked "lots of times": Twenty-six percent of females in comparison with 11 % of males became "regular smokers".
Sixty-five percent of Maori females had tried smoking compared to 16% of Non- Maori females. Fifty-five percent of Maori females vs. 35% of Non-Maori females were current smokers. Forty percent of Maori females were "regular smokers" •compared- to only 15% of Non-Maori females.
Among Maori in our sample, four times as many females (40%) as males (10%) were "regular smokers".
xix Hawkes Bay had the highest percentage of subjects who had tried smoking at least once (77%), the highest percentage who had "Smoked lots of times (38%) and the highest percentage of current "regular smokers" (24%). The majority of subjects in our sample either purchased their cigarettes themselves or obtained them from friends.
Female students (54%) are more likely to purchase cigarettes from a shop in comparison with male students (40%). Maori students were more likely to purchase cigarettes from a shop (64%) and ask their parents for cigarettes (25%) in comparison to Non-Maori students (46%, 10%, respectively).
A third of 12-13 year olds and half the 14-15 year olds reported they purchased their cigarettes from a shop.
The most frequently recalled cigarette brand names were: Winfield (cited by 59% of the sample), Pall Mall (60%), Benson & Hedges (47%), Rothmans (43%), Holiday (32%), Peter Jackson (31%), John Brandon (23%), Camel (13%), Marlboro (11 %), and Dunhill (11%).
It is of significance that the major cigarette brand names recalled are those brands that sell and those associated with major tobacco sponsorships. Pall Mall (cited by 27% of smokers in the sample), Winfield (26%), Benson & Hedges (15%), Rothmans (13 %), Holiday (10%), John Brandon (9%), Peter Jackson(7%), Dunhill (4%) were the brands most "usually smoked" by our sample. It is of significance to note that the major cigarette brand names recalled by the 12-17 sample are also the main brands that sell and the main brands associated with major tobacco sponsorships.
Taste was identified as the main reason for brand preference by 55% of smokers in the sample followed by price (21%). Forty-four percent of the students who smoked had no brand preference.
Only three brands of cigarettes were significantly associated with sporting events. These were Winfield (cited by 50% of the sample), associated with rugby league, soccer and softball, Benson & Hedges (28%) associated with Tennis, and Rothmans (26%), associated with car rallying, motor cycle racing and car racing. Twenty-four percent of the sample knew that Benson & Hedges sponsored fashion awards.
Activities believed to be Smokefree sponsored were Netball (cited by 31% of the sample), Basketball (19%), and Rockquest (4%). There were highly significant correlations-- between Brand Awareness, Brand Preference and Brand Association with Sport.
xx Retailer survey Sixty-one percent of the respondents indicated that could recall receiving information regarding the requirements related to the Smokefree legislation. Over sixty percent of the respondents cited the Department of Health as the leading source of information about the Smokefree legislation. Nearly all retailers who received information recalled it involved the sale of cigarettes to under 16 year olds. Nearly two-thirds of respondents recalled receiving information about Smokefree workplace policies. Approximately half the retailers considered they understood the requirements of the Smokefree legislation and half thought they understood some of the requirements.
Three out of four "new" retailers wanted further information in comparison with half the "established" retailers.
Only a third of retailers indicated they had received support or assistance from the Department of Health and tobacco companies, respectively, in association with the S mokefree legislation. A high number of the respondents reported that they had received the sticker indicating they could not sell cigarettes or tobacco to under 16s. Three quarters of the retailers indicated is was difficult for them to tell if the customer was under 16 years of age.
Retailers indicated a number of options would make it easier for them to determine the age of customers, such as, the carrying of photo ID cards, and increasing the age of legal purchase of tobacco products to 18 years, although retailer views about this latter option were divided.
Retailers indicated they required further support and help in the following areas: more updated information about the Smokefree legislation, more display signs which are larger than presently used, multilingual sings, and further public education of the requirements of the Smokefree legislation. Retailers indicated that they would like further specific information on the Smokefree legislation, such as, legal information and notification of any changes in the Smokefree legislation.
Just over half the respondents agreed with the statement that no new tobacco product advertisements may be put up in or outside shops. Just over three quarters of the retailers agreed that tobacco advertising signs without a health warning must. be removed. Forty-five percent of respondents agreed with the statement that all tobacco product advertising signs must be removed after 1 January 1995. Just under half the retailers agreed with the statement that tobacco product price displays inside the retail outlet must not exceed the size of 3xA4 sheets.
xxi Just under half the retailers agreed with the statement that tobacco product price displays inside the retail outlet must not exceed the size of 3xA4 sheets. Only 38 percent of retailers agreed that they could be fined up to $10,000, if convicted, for putting up new tobacco advertisements. Only 15 percent of retailers indicated that they sold cigarettes singly. The vast majority of retailers sold cigarettes in packets, with the most frequently sold being: 20s (97 percent), 25s (96 percent), and lOs (91 percent). Cartons were sold by 72 percent of the respondents. Problems related to Part II of the Smokefree legislation include:
E The language of the Smokefree Environments Act, 1990 The "Grandfather Clause"
U Enforcement
The report will assist the Ministry of Health, Public Health Commission, Regional Health Authorities, Crown Health Enterprises and other provider groups, to further develop policy and health promotion and education practices to determine what additional resources and strategies will be required to fully implement the intention of the Smoke-free Environments Act, 1990.
rov Chapter 1 Introduction 1.1 Introduction
It has been estimated that cigarette smoking causes over 4000 premature deaths in New Zealand every year (Toxic Substances Board, 1989). The United States Surgeon stated in 1989 that cigarette smoking is:
• a cause of early death in men and women • a cause of increased overall morbidity • the major cause of bronchitis • the major cause of emphysema • the major cause of lung cancer • a major cause of coronary heart disease.
As well as the human costs associated with cigarette smoking their are accompanying economic costs. Phillips, et al. (1992) estimated the cost of smoking to New Zealand health services at $185.4 million in 1989. These are only costs to the health system, there are costs associated with illness absenteeism resulting in lost employment productivity and premature morbidity and mortality resulting in loss of income and tax revenue.
Cigarette smoking is clearly a major public health issue in New Zealand.
On August 28 1990 the Smoke Free Environments legislation was enacted. Historically there was a forty year build up to The Smoke Free Environments Act (1990). Some of the key events associated with this build up are summarised as follows:
1948 Department of Health began to mention the hazards of smoking in the print and radio media.
1954 The first Cancer Register was started in New Zealand.
1959 Department of Health produced a poster which spelt the word CANCER from cigarette smoke.
1960 A pilot survey on smoking habits in children from nine schools was conducted which revealed boys began smoking at 12 years of age and girls at 13 years of age.
1961 National Tobacco Company removed the words "Does not affect heart or throat "from tobacco packets.
1962 No cigarette advertising was permitted before 7. 3Opm on television and advertising was not accepted on the radio or television that encouraged young people to smoke.
1963 .Department of Health mentioned the policy of discouraging young people from taking up cigarette smoking in their annual report.
No cigarette advertising on television or radio.
1 1965 department of Health produced special report (No. 16) on "Smoking habits of New Zealand doctors".
1966 Minister of Health said the use of health message warnings on tobacco packets was under consideration.
1971 National Heart Foundation produced a report on Coronary Heart Disease which stated cigarette smoking as a major risk factor and recommended further promotion of non-smoking as apart of education.
1973 Voluntary agreement between the Minister of Health and three tobacco companies to ban advertising on cinema and billboards and formalise the ban of advertising on television and radio.
1974 Air New Zealand offered passengers non-smoking seats.
Warnings on cigarette packets, weak wording.
1976 Government established an Advisory Committee on Smoking and Health.
WHO recommended that Governments establish programmes for the control of smoking.
Census question on smoking.
1979 Tobacco is classified as a toxic substance under the Toxic Substances Act (1979).
Restrictions on advertising content in print media.
TV campaign to help teenagers stay non-smokers.
1980 The Tobacco Institute was founded.
1981 Health Education and Resource Project (HERP) produced non-smoking material for school children.
1982 Action on Smoking and Health (ASH) and the Tobacco Advisory Council were formed. III Smoking intervention teacher kits issued to schools
1983 First published- estimates of 3,600 deaths due to smoking. 1984 Departmental medical officer for tobacco control. II 1985 The Advisory Committee on Smoking and Health produced a report of proposals for a comprehensive policy on the promotion of non-smoking. II A
2 0 I 1986 Great New Zealand Smoke Free Week.
Smokeless tobacco banned.
Toxic Substances Board produced a report on the advertising and promotion of tobacco.
Price of tobacco products raised 54 percent.
1987 Agreement signed between the Minister of Health and Rothmans (NZ) Ltd. and WD & HO Wills (IsiZ) Ltd. outlining restrictions for tobacco product control. The agreement included the provision for inclusion of health warning messages on cigarette packs and on containers containing other tobacco products, except cigars.
Department of Health offices become smoke-free
1988 Age restriction banning sales to those under 16 included as a regulation of the Toxic Substances Act.
Department of Health publishes book entitled "The Big Kill".
Further estimate published: 4000+ deaths due to cigarettes.
Reserve Bank credit for tobacco growers stopped.
Creating smoke-free indoor environments published.
Strong varied warnings on tobacco packets.
1989 The Coalition against Tobacco Advertising and Promotion launched.
The New Zealand Health Charter launched with smoking reduction as one of ten health goals and targets.
Tobacco taxation indexed to consumer price index.
The Toxic Substances Board publishes a report "Health or Tobacco". 1990 The Smoke-Free Environments Act 1990 became law.
The Smoke-Free Environments Act (1990) has three main aims and parts: Part I : seeks to reduce exposure on non-smokers to tobacco smoke by legislating controls on smoking at workplaces, public areas and other enclosed places. Part II: seeks to legislate restrictions on the marketing, advertising, and promotion of tobacco products through sponsorship. One of the aims of Part II is to regulate tobacco advertising in all shops and in the media. Part III: involves the establishment of the Health Sponsorship Council to "promote health and healthy lifestyles through sponsorship" and to provide an alternative sponsorship source on those "individuals formerly dependent on the tobacco industry for funding or sponsorship".
1.2 What this report covers This report is divided into three distinct sections. Section one reviews the literature adolescent smoking behaviour and knowledge and details the strategies that have been used to prevent adolescents from starting smoking or smoking cessation programmes directed at adolescent smokers. Section two reports the findings of a smoking behaviour and knowledge survey conducted with 890 New Zealand adolescents between 12 and 17 years of age. The results update a similar national survey of New Zealand adolescents conducted by the National Research Bureau in 1991 (National Research Bureau, 1991). Section three focuses on Part II of The Smoke Free Environments Act (1990). The findings of a national survey of retailers support, understanding, knowledge and information requirements related to Part II of The Smoke Free Environments Act (1990) are reported.
1.3 Aims and purposes of the research
Health Research and Analytical Services, Department of Health, has been commissioned by the Public and Personal Health section of the Department of Health to conduct this research. The aims of the research are:
To examine the smoking behaviours/habits in a random sample of 12-16 year old school children.
• To examine the awareness of advertising and brand promotion of tobacco products and their association through sponsorship with sporting and non- sporting events in a random sample of 12-16 year old school children.
To determine what additional information and support retailers need to comply with the Smoke-free Environments Act (1990), especially Part II of the Act.
The report will assist the Ministry of Health, Public Health Commission, Regional Health Authorities, Crown Health Enterprises and other provider groups, to further develop policy and health promotion and education practices to determine what additional resources and strategies will be required to fully implement the intention of the Smoke-free Environments Act, 1990.
4 n Chapter 2 Review of Literature on Adolescent Smoking Behaviour
2.1 Introduction
"Tobacco smoke is a lethal cocktail containing the same chemicals that are found in rocket fuel, floor cleaner, paint stripper, mothballs, insecticide, ant poison, and the gases people use to commit suicide from car exhausts, and to kill people in gas chambers. And that s only naming a few". (Reid and Pouwhare, 1991) Research into the prevention (or cessation) of adolescent smoking is crucial since it appears that most smokers start smoking in their adolescent years. For example, in the U.S. 90% of all new smokers begin smoking before the age of 21 (U.S. Centers for Disease Control, 1990 A) and 20-30% of smokers become regular users by the age of 18 (Gritz, 1984).
The spontaneous quit rate in the adolescent years is estimated at 25% (among regular smokers), with the probability of cessation declining as the number of years of regular smoking increases (Gritz, 1984).
Tobacco consumption is reducing, for example, 1975 2873 cigarette equivalents per adult; 1986 2117 cigarette equivalents per adult; 1991 1783 cigarette equivalents per adult; and 1992 1600 cigarette equivalents per adult.
There is, however, concern that tobacco consumption in a subset of the population, young people, is not reducing at the same rate as for the total population (Shaw, et. al., 1991). Also, the incidence of regular smoking is higher for Maori in comparison with Non-Maori and higher for girls in comparison with boys (National Research Bureau, 1991; Shaw, et. al., 1991).
5 2.2 Aims of the literature review
The aims of the literature review were with respect to the following five topics:
(i) The smoking behaviours and habits of adolescents
To describe and review the main findings and themes of New Zealand surveys on adolescent (up to 16 years of age) smoking behaviours and habits. To establish trends/changes over time in smoking behaviours/habits.
(ii) Tobacco promotion and adolescent smoking
To describe and review the effects of tobacco promotion/advertising on the uptake of smoking by adolescents.
(iii) Proven health promotion strategies
To review health promotion strategies, programmes and/or policies directed at (i) preventing the uptake of smoking in adolescents and (ii) the cessation of smoking in adolescents. Review of this material should include the feasibility/acceptability of using these strategies in the New Zealand context.
(iv) Contemporary adolescent lifestyles and their impact on smoking behaviours and habits
To conduct an examination of sociological and historical writings that illuminate the range of lifestyles or sub-cultures currently available to young people in New Zealand, including an investigation of how these may impact on adolescent s beliefs and behaviours about smoking.
(v) The sale of cigarettes to "minors"
To describe and review the extent to which retailers in New Zealand and overseas are selling cigarettes and tobacco products to "minors".
To review health promotion strategies, programmes and/or policies directed at preventing the sale of cigarettes and tobacco products to "minors". Review of this material to include the feasibility/acceptability of using these -strategies in the New Zealand context.
rol 23 Literature review methods The main sources of information included: an on-line computer search of databases for relevant books, articles, reports and newspaper clippings; • published and unpublished reports and documents provided by key informants; and • recent journals were scanned for relevant articles.
2.4 Health and tobacco use
2.4.1 Health risks for tobacco users Causal relationships have been found to exist between smoking and lung cancer, as well as cancers of the esophagus, bladder, kidney, larynx and oral cavity, pancreas and stomach. Eighty-five percent of lung cancer deaths and 30% of all cancer deaths are attributable to smoking. Plus smoking appears to be the most important modifiable factor for coronary heart disease with 30% of all coronary heart disease deaths being attributable to smoking. (Hynes, 1989) Smoking has also been found to have a lowering effect on systolic blood pressure, even in young occasional users (St George et al., 1991). Smokeless tobacco (oral snuff and chewing tobacco) has been associated with oral cancer, leukoplakic lesions, and gingival and periodontal disease (Goldsmith, 1988). Regular day long use achieves levels of nicotine in the blood, and causes changes in heart rate and blood pressure, similar to those observed in smokers (Goldsmith, 1988).
Carr-Gregg and Gray (1989) estimate that 15% of all deaths in New Zealand are attributable to cigarette smoking. This figure is an underestimate since it does not include those deaths due to passive smoking or pipe smoking. Individuals who start smoking as children put themselves at greater risk of dying prematurely or being disabled by tobacco induced diseases (Stanwick et al., 1987). Resnicow et al. (1991) suggested that approximately 35% of all smokers die prematurely and in The Big Kill (Department of Health, 1988) it is stated that at least one in four smokers die prematurely (on average 15 years ahead of their time) often after months or years of illness.
7 2.4.2 Health risks, tobacco use, and gender/ethnicity Maori men and women have one of the highest recorded incidences of lung cancer in the world; 15% of the higher overall total death rate for Maori compared with Pakeha is attributable to higher smoking rates amongst Maori (New Zealand Health goals and targets, 1989). The lung cancer rate in New Zealand women tripled between 1964 and 1986 and is still rising. Lung cancer rates for Maori women are over four times higher than those of non Maori women, and are the highest in the world. (Ministry of Womens Affairs, 1990) There are also gender-specific risks associated with smoking amon women, for example, cigarette smoking increases the risk of coronary heart disease among women several times, and among oral contraceptive users about 10 times (Hynes, 1989).
2.4.3 Health risks for the unborn child and the passive smoker Strong relationships exist between smoking during pregnancy and reduced birthweight of infants, spontaneous abortion, sudden infant death syndrome, fetal growth retardation, preterm delivery, and intellectual and behavioural defecits in the child (Hynes, 1989). Not only are there serious health risks for the smoker and the unborn child of a smoker, but also for the passive smoker. Non smokers who spend a significant amount of time in smoke filled environments, either at home or at work, may assume the same risks as light smokers. For example, Kawachi et al. (1989) estimated the total number of deaths due to passive smoking from lung cancer (30) and ischaemic heart disease (243) to be a total of 273 per year in New Zealand. Children are especially vulnerable to tobacco smoke. Children who are brought up in smoke filled homes are more likely to get blocked and runny noses, sore eyes, earache and glue ear, coughing and chest infections, asthma, and cancer. (Reid and Pouwhare, 1991)
2.4.4 Financial costs versus financial gains It has been questioned whether the financial gains (revenue from taxation and reduced health care spending on the aged because of reduced life expectancy) may outweigh the financial losses due to smoking (increased health care costs for smokers). Hodgson (1992) evaluated whether lifetime medical expenditure is greater for smokers or never smokers. The associated costs of non smoking (for example, medical care for the elderly due to greater life expectancy) were compared with the medical costs of being a smoker (for example, treatment for lung cancer). Hodgson concluded that "the cumulative impact of excess medical care required by smokers at all ages while alive outweighs shorter life expectancy, and smokers incur higher expenditures for medical care over their lifetimes than never smokers". On the basis of these findings, Hodgson argued that "reductions in the number of persons who ever smoke and the amounts smoked will benefit all payers
LV of medical care, decreasing the financial obligations of both public and private sources of funding". In New Zealand it has been estimated that each year 4,815 years of working life are lost due to cigarette smoking induced premature mortality (Gray, 1988). In 1992, excess use of hospital services caused by cigarette smoking in New Zealand was estimated to cost at least $110 million each year (March 1992 dollars) (Department of Health, 1992). DiFranza and Tye (1990) estimated that approximately 3% of tobacco industry profits in the U.S. derive directly from the illegal sale of cigarettes to children and that about half of the American tobacco industry s annual profits derive from sales to people who became addicted to nicotine as children. But despite these profits, it was found that tax revenues to federal and state governments from cigarette sales to children dwarfed governmental expenditures on smoking and health.
2.4.5 Conclusions Since every year adults die from smoking related diseases or quit smoking, new customers must be obtained so as to maintain tobacco sales. Many of these new "customers" are recruited from children and adolescents. (Stanwick et al., 1987) Children who begin smoking in early adolescence are likely to continue smoking as adults, whilst those who postpone smoking until their later adolescence are less likely to start smoking and are more likely to quit smoking as adults. (Stanwick et al., 1987) Children who begin to smoke at a young age are also more likely to consume more cigarettes daily than those who start later in life (Moss et al., 1992). Therefore all legitimate means by which smoking initiation can be delayed need to be explored. To achieve this aim it has been suggested that "a comprehensive and well-orchestrated program of education, taxation, and legislation" may be required for success (Stanwick et al., 1987). 2.5 Smoking prevalence - International literature Smoking behaviour begins primarily in adolescence. Regular smoking leads to the development of a dependence process, with cessation often difficult to achieve and maintain, therefore smoking onset is a responsibility of health professionals and educators. (Gritz, 1984)
2.5.1 Smoking prevalence amongst U.S. adults Despite the decline in overall prevalence of cigarette smoking (see table 2.1) in the U.S. (from 42.3% in 1965 to 25.5% in 1990), there has not been a corresponding decline in the actual number of adult smokers due to increases in population size (Giovinoi et al., 1992). For U.S. adults, a 1990 survey revealed that in all sociodemographic groups, the prevalence of smoking was higher among men than among women; and highest among persons aged 25-44 years, American Indians/Alaskan Natives, Non Hispanics, and persons with fewer than 12 years of education. Current smokers (defined as those who smoke one or more cigarettes per day) were found to smoke on average 19.1 cigarettes per day, with 22.9% of current smokers reporting smoking 25 or more cigarettes per day. (U.S. Centers for Disease Control, 1992 C)
2.5.2 Trends in smoking prevalence amongst adolescents
2.5.2.1 U.S. A number of studies have looked at how many U.S. adolescents smoke, how often they smoke and how much they smoke (see tables 2.2 and 2.3). DiFranza et al. (1987) found that the average age for the first use of cigarettes by adolescents was 13 years, and for snuff, 10 years, despite the legal age for purchase being 18 years in most U.S. States. A 1989 survey revealed that an estimated 1.7 million U.S. youths had smoked a whole cigarette before their 12th birthday (Moss et al., 1992). A 1989 survey revealed that the average number of cigarettes smoked by teenagers increases with age and that about three teenagers in four who were current smokers had made at least one serious attempt to quit smoking cigarettes (Moss et al., 1992). A 1991 survey found that the percentage of adolescents who had tried cigarette smoking and used cigarettes frequently increased significantly between the ninth and twelfth grade (14-18 years), with twelfth grade students being nearly twice as likely as ninth grade students to use cigarettes frequently (U.S. Centers for Disease Control, 1992 B).

13 Trends over time have also been identified. O Malley et al. (1988) examined substance use among American youth (18 to 24 years) from high school classes of 1976 to 1986 and found that cigarette use declined with successive cohorts; regular users increased their amount of cigarette use soon after leaving high school; and whereas a very few individuals may initiate regular smoking after high school, practically no one does so after age 21. Resnicow et al. (1991) found that among high school seniors (17-18 years), daily smoking (at least one cigarette per day) peaked at around 29% in 1976-1977 but declined to 18% by 1984. However, it seems that since 1984 there has been little change. Heavy smoking (> 1/2 pack per day) was also found to have declined from 19.4% in 1977 to 10.6% in 1988. The percentage of students who perceived smoking as very harmful increased from 51% in 1975 to 68% in 1988 and students who disapproved of people who smoke also increased slightly from 68% in 1975 to 73% in 1988. Bush and lannotti (1993) surveyed fourth grade Washington DC students in 1988/89 and 1990/91. Comparisons of data for the two periods revealed that the lifetime prevalence of smoking more than a puff of cigarettes had declined (1988/89: 13.5%; 1990/91: 11.4%) but cigarette experimentation had not (1988/89: 4.9%; 1990/91: 6.3%). Environmental variables associated with cigarette use which declined were being offered cigarettes by peers and pressure by friends to use. No declines were observed in family use, perceived friends use, or being bothered a lot if best friends use. The prevalence of smokeless tobacco use should not be ignored when discussing overall tobacco use in the United States. Goldsmith (1988) reported that smokeless tobacco products are used by an estimated 22 million people in America (only about 2% females) and many of the males who dip snuff and chew tobacco are very young. Unlike sales of cigarettes which have shown a decline, smokeless tobacco usage has remained steady or increased (Goldsmith, 1988). Glover et al. (1989) found that 23% of college students who began smoking before the age of ten were current smokers, while 61% of those who began using smokeless tobacco before the age of ten were current smokeless tobacco users. College students were more likely to switch from smokeless tobacco to cigarettes then from smoking cigarettes to smokeless tobacco. A 1990 survey revealed that 1%-20% (median:11%) of 9th to 12th grade students (14-18 years) across the United States, reported using smokeless tobacco in the thirty days preceding to the survey (U.S. Centers for Disease Control, 1991 D).
2.5.2.2 Australia An Australian survey of secondary school children (12-17 years) conducted in 1987 found that current smoking (that is, smoking at least one cigarette in the last week) rose with age to 27% in boys aged 16 years and to 30% in girls of the same age. When compared with an identical survey in 1984, it was found that the prevalence of smoking among 12-15 year Old schOolchildren had -fallen significantly. (Hill et al., 1990)
14 ID 2.5.3 Gender differences in smoking trends Gritz in 1984 argued that the evidence points to an increase in female smoking in each age group with the rate of female smoking exceeding that of the male rate of smoking without any convincing evidence of any downturn.
2.5.3.1 U.S. Smoking rates have declined in the United States since 1963, but this trend has been less apparent in adolescents, especially girls. In girls aged 17 to 18 years, smoking prevalence has increased from 1968 to 1979 and since 1979, female adolescents have smoked at rates that surpass those of male adolescents (Davis et al., 1990). Indeed, teenage girls comprise the largest percentage of new cigarette smokers in the United States (Hynes, 1989) with consistently higher smoking rates for females than for males (Windom, 1988). A number of studies have documented a higher smoking prevalence in recent years by female adolescents compared with male adolescents. Waldron et al. (1991) analyzed cigarette smoking patterns in a national (U.S.) sample of White high school seniors in 1985. Females were found to be more likely than males to have ever smoked a cigarette and among those who had ever smoked, females were more likely to have smoked more than twice. However, females were not more likely to have progressed in the subsequent stages of smoking adoption, and among current smokers, males were more likely to smoke at least half a pack a day. Females were found to be as likely as males to have quit smoking. Glover et al. (1989) found that female college students were more likely to smoke than male college students (16% versus 13%), but males were more likely to use smokeless tobacco (22% versus 2%). In a study of teenage smoking trends during pregnancy, Davis et al. (1990) found that there was a small but significant increase in the overall smoking prevalence during pregnancy between 1984 (32%) and 1988 (37%). Unmarried pregnant teenagers had a smoking prevalence of 42.8%, compared with a rate of 31.7% in married teenagers and pregnant teenagers had a much higher smoking prevalence than their non pregnant smoking peers. There are some indications however that this trend may be levelling off. Resnicow et al. (1991) found that between 1978 and 1987, daily and heavy smoking were more prevalent among female high school seniors than male high school seniors (17-18 years). In 1988, however, there were no gender differences in daily smoking, although males were slightly more likely to report heavy smoking. Among eighth (13-14 years) and tenth (15-16 years) graders in 1987, girls were slightly more likely than boys to have reported smoking in the past month (13.7% versus 12.4%). The Teenage Attitudes and Practices Survey (TAPS) (Moss et al., 1992) conducted in 1989 found that about the same proportions of boys and girls reported that they currently smoked. This trend was noted regardless of age. Among smokers 16-18 years of age, 55% of malesmokers and 46% Of female smokers met the TAPS heavy smoker criteria. Similar proportions of male and female smokers smoked on about the same number of days a month, but females reported smoking fewer cigarettes on the days that they did smoke.
15 The same survey also revealed that school dropouts who were male were more likely to report having smoked during the previous week than were dropouts who were female (U.S. Centers for Disease Control, 1991 A). A 1990 survey of 9th to 12th grade students (14-18 years) found that the prevalence of any tobacco use was significantly greater among male students (40.4%) than among female students (31.7%), especially for smokeless tobacco use (males: 19.1%, females: 1.4%). Current cigarette use (smoking cigarettes at any time during the 30 days preceding the survey) and frequent cigarette use (smoking cigarettes on more than 25 of the 30 days preceding the survey) were about the same for both males and females (33.2% vs 31.3%; 13.0% vs 12.5%). (U.S. Centers for Disease Control, 1991 B). Despite these encouraging signs, it is still too early to tell if these positive trends will continue.
2.5.3.2 Australia Woodward et al. (1989) reported that despite the overall prevalence of smoking in Australia declining over the last 15 years, rates among young women have increased. Gliksman et al. (1989) found that by 15 years of age, 32.4% of Australian girls and 26% of Australian boys had smoked at least one cigarette in the seven days before they were surveyed. In some of the age groups, the average number of cigarettes that were consumed by girl smokers equalled or exceeded that of their male counterparts.
2.5.3.3 Great Britain Reid (1985) stated that in Britain smoking has declined amongst boys but increased among girls since 1966. In a British study, Epstein et al. (1989) found that 23% of all the girls and 19% of all the boys (12-17 years of age) reported that they smoked cigarettes, 7% apparently often or everyday.
2.5.4 Ethnic differences in smoking trends
2.5.4.1 U.S. In the U.S., consistent and significant differences in smoking prevalence rates between White, Black, Hispanic, Asian, and Native American adolescents have been found (see tables 2.4 and 2.5). White adolescents have been found to start smoking earlier, for example, Headen et al. (1991) found that Whites were more likely to start smoking at age 12 and Blacks at age 14; and to be more likely to continue smoking and smoke more than either Hispanic or Black adolescents, with this difference being greatest between White and Black adolescents. White male students (23.6%) are also significantly more likely than any other group to report smokeless tobacco use (U.S. Centers for Disease Control, 1992 B). Resnicow et al. (1991) argued that this gap between White and Black smoking has widened since 1976 with Black adolescent smoking decreasing at greater rates than White adolescent smoking. Black teenagers who currently smoke have also been found to be more optimistic about smoking
16 cessation than their White counterparts (24% and 45%, respectively, predicted smoking the next year). (The U.S. Centers for Disease Control, 1991 A; Moss et al., 1992) When ethnic differences in not only smoking, but also drinking and illicit drug use among U.S. high school seniors over the period 1976-89 were analysed, Bachman et al. (1991) found Native Americans to have the highest prevalence rates overall for cigarettes, alcohol, and most illicit drugs; Whites had the next highest rates for most drugs. Asian Americans had the lowest prevalence rates, and Black students had levels nearly as low except for Marijuana. Prevalence rates for the Hispanic groups were mostly in the intermediate ranges except for relatively high cocaine use among the males. Prevalence rates for daily use of cigarettes were found to have declined for all subgroups with cigarette use declining more sharply for Black than White seniors. Hence it has been consistently found that sinificantly less Black adolescents smoke than White adolescents. This finding is inconsistent with adult prevalence rates where more Blacks than Whites smoke (34% versus 29%) (Resmcow et al., 1991). Drug related mortality and morbidity are also higher among Black adults than White adults (Bachman et al., 1991) and while Black adolescents are less likely than White adolescents to smoke, it seems that Black adults are more likely than White adults to start smoking after adolescence (U.S. Centers for Disease Control, 1991 E). Bachman et al. (1991) suggested that these findings may be an artifact of the "two worlds" of drug use existing within the Black community: the extremes of abstinence at one end and heavy use/abuse at the other. Siegfried (1991) on the other hand reported suggestions that low rates of cigarette use by Black adolescents may relate to lower levels of disposable income compared with White adolescents or that Blacks have different social norms and spend their money differently.
2.5.4.2 Australia Like North America, ethnic differences have been identified in Australia. Gliksman et al. (1989) surveyed Australian school children and found that ethnic origin was a statistically significant predictor of smoking behaviour in children. Significantly fewer children of Asian ethnic origin were current smokers. Upon closer examination of the Asian data it was found that while the prevalence of smoking was very high among many Asian men, it was very low among Asian women. Guest et al. (1992) looked at the smoking prevalence of Australian Aborigines and persons of European descent in two country towns. Of the Aborigines, 64.4% were current smokers, compared with 22.8% of non Aborigines. For persons aged 13 to 54 years, using the five categories of exposure (current smokers, non smoker, <10 cigarettes per day, 10-20 cigarettes per day, >20 cigarettes per day), smoking by Aborigines was found to far exceed that of non Aborigines in all age groups. In non Aboriginal females, the highest prevalence was in the youngest gr up (560/o of those aged 13 to 17 years).

19 2.5.5 Conclusions Overseas surveys have observed a significant decline in the smoking prevalence of adults, accompanied by a somewhat less striking and more recent decline in the smoking prevalence of adolescents. These declines in smoking prevalence have been less marked for females than for males, although the disturbing trend for females to have higher prevalence rates than for males seems to be levelling off with recent U.S. surveys identifying few gender differences. Ethnic differences in smoking have also been identified in both the U.S. and Australia. For example, in the U.S., Whites have been found to be more likely to start smoking earlier, to be more likely to continue smoking, and to smoke more than Hispanic and Black adolescents. Whatever the reasons for the ethnic and gender differences identified in the United States, Australia and Great Britain, it can be argued that there is sufficient evidence to support the view that smoking prevention., reduction, and cessation programmes will become more effective if they incorporate ethnic and gender factors into their programmes (Rogers and Crank, 1988).

- U 2.6 Smoking prevalence - New Zealand
2.6.1 Historical Background Just over 200 years ago, tobacco was brought to New Zealand by the early Pakeha explorers and traders. Tobacco soon became popular as an article of trade and the Maori took up tobacco with enthusiasm. Tobacco was cultivated and cured by the Maori for both personal use and local trade. (Reid and Pouwhare, 1991) Prior to World War I, smoking tobacco as tailor made cigarettes was still relatively uncommon with pipes still being the most common way to smoke tobacco. But during World War I cigarettes were distributed free to soldiers and there was a huge increase in the number of young men who used tobacco in the form of cigarettes. Free cigarettes were again provided to troops during World War II. (Reid and Pouwhare, 1991) During the 1920s and 1930s there was an increase in cigarette smoking by women in the western world. It has been suggested that this may have reflected to some extent womens increased independence and freedom. It also marked the time when women first became the targets of advertising campaigns. Cigarettes grew in popularity and social acceptability during this period. (Reid and Pouwhare, 1991) Due to increasing health concerns, filter tips were introduced in the 1950s and mild and low tar brands were introduced in the late 1970s to help allay these health concerns. (Reid and Pouwhare, 1991) In New Zealand, tobacco use amongst Pakeha men became less common during the 1950s when information about tobacco related diseases first became available. This decline was not copied by Pakeha Women or by the Maori. For example, tobacco use became more popular with Pakeha women from World War I and the high rates of tobacco use by Maori men did not decline. Maori Women also have had a high tobacco usage for most of this century. (Reid and Pouwhare, 1991)
2.6.2 Smoking prevalence amongst New Zealand adults
2.6.2.1 In general One in four adult New Zealanders (25%) in 1990 were smokers with an average consumption of 12 cigarettes a day. Forty-six percent of all New Zealanders had never smoked and 29% were ex-smokers. (Hilary Commission Report, 1991) A 1991 survey (N.R.B., 1991) concluded that current smoking status has changed very little since 1989. In both 1989 and 199123% were found to currently smoke 1 or more cigarettes a day. Fifty-three percent in 1991 reported having never smoked regularly compared with 52% in 1989; and 24% in 1991 reported that they used to smoke regularly compared with 25% in 1989. Those who smoked in 1990 reported that they consumed fewer cigarettes per day on average than their counterparts in 1983 (Department of Health/Department of statistics, 1992). Actual consumption of tobacco products per person aged 15 years or over has decreased by 46% from 1963 to 1991 (Department of Health, 1992)
21 11 and since 1989 the average number of cigarettes smoked by current smokers has gone down from 13.2 to 12.8 in 1991 (N.R.B., 1991). II Regardless of whether people are current smokers or smokers who have given up, the peak age for beginning to smoke has been found to be around 15-16 years of age. Amongst current smokers, 24% began smoking some time before they were II 15; 34% at 15-16; 21% at ages 17-18; and a further 21% were older than 18 when they began. (N.R.B., 1991) II A 1991 survey (N.R.B., 1991) revealed that 86% of adults agree that the health of people can be damaged by exposure to others tobacco smoke. More smokers in 1991 agreed that tobacco smoke can be damaging to the health of non smokers than they did in 1989 (74% compared with 66%). Despite these findings, the II Hillary Commission (1991) found that 39% of non smoking New Zealanders spend an average of 3.8 hours per day in a confined space with someone else is smoking. II Eighty-one percent of adults believed that there are particular illnesses or diseases caused by smoking. The main ones mentioned were: lung cancer (46%), cancer (unspecified) (27%), heart disease (26%), emphysema (22%). Amongst current smokers, 77% nominated various illnesses caused by smoking (N.R.B., 1991). II Eighty-seven percent of both current and former smokers agree that smoking is addictive but only 77% saw their own use of cigarettes as a form of addiction. Just II over one in five smokers did not believe that their own cigarette smoking was a form of addiction. (N.R.B., 1991) II A recent Public Health Commission Report (Brown, 1993) identified recent major trends in tobacco consumption in New Zealand. During the period 1984-1992, there was a 42% decline in the tobacco products available for consumption per adult; compared with a 11% decline in the period 1970-1983. Tobacco products II available for consumption, per person aged 15 years and over, fell 10% during 1992 continuing this downward trend and in 1992, 1,600 cigarette equivalents per adult were available compared with 1,783 in 1991. In the period 1970-1985, II manufactured cigarettes as a proportion of all tobacco products steadily increased from 83% to 92%, but by 1992 this proportion had declined to 82%. During the period 1984-1992 there was a 44% increase in the amount of loose tobacco available for consumption in the period 1984-1992. II
2.62.2 Gender differences A In New Zealand, cigarette consumption has declined since 1983 but this decline has been more marked for men then for women. Since 1986, the number of women II who smoke has remained consistently higher than that of men aged 15-24 years. In both 1983 and 1990 a greater proportion of females aged 15-24 years reported that they smoked, but at ages 25 and over, similar proportions of males and females reported that they smoked. Males aged 25 and over reported an average daily -11 consumption of 16 cigarettes in 1990, two more than females of the same age. At ages 15-24, men and women alike reported smoking an average of 12 cigarettes per day in 1990. (Department of Health/Department of statistics, 1992) - 11 . U In 1991, tobacco was used by approximately 27% of males and 25% of females. The proportion of males aged 15 years and over who smoke decreased from 32% II in 1976 to 27% in 1991, while the proportion of adult females who smoke decreased from 31% in 1983 to 25% in 1991. In the 15-24 year age group, the II II 22 II percentage of female smokers was higher than the percentage of male smokers. (Department of Health, 1992) The Life In New Zealand Survey (Hillary Commission, 1990) reported that the proportion of men and women smoking did not differ but a greater proportion of women (51%) than men (42%) have never smoked. More young and middle aged women (15-44 years) were smokers (29%) than any other group of either gender. The survey also found that more men than women were subjected to passive smoking (43% versus 34%). The same survey (Hillary Commission, 1991) also reported that smoking prevalence among males increases to 25-44 then progressively reduces to 65+ years of age. Smoking prevalence among young women remains relatively high until 25-44 when it also declines over age to 65+. Fifty-five percent of men and 52% of women smokers have quit.
2.6.2.3 Ethnic differences The uptake of smoking among Maori is among the highest in the world, while the quit rate amongst Pakeha, especially Pakeha men, has greatly increased in the last 15 years (Reid and Pouwhare, 1991).
Reid and Pouwhare (1991) report that in 1981, 53.5% of Maori men and 58.5% of Maori women were regular smokers; compared with 33.1% of non Maori men and 27.3% of non Maori women. The Life In New Zealand Survey conducted in 1990 (Hillary Commission, 1991) found that 38% of male Maoris currently smoked, 24% had never smoked, and 50% of those who had ever smoked had quit. These figures compare with 25%, 44% and 58% for other New Zealanders respectively. Double the proportion of Maori women were found to smoke (44%) compared with other New Zealand women (22%). Considerably fewer of the Maori women smokers (41%) had quit compared with other New Zealand women (54%). In 1989, 61% of Maori women in the 15-34 age group smoked cigarettes compared with 44% of Maori men of the same age (Department of Health/Department of statistics, 1992). Recent surveys have shown a decline in tobacco use among Maori men down to 49.4% in 1989 and 45.1% in 1990 suggesting that fewer young Maori men are either taking up smoking or continuing to use tobacco throughout their adult lives (Reid and Pouwhare, 1991). For Maori women, however, there has been no clear evidence that smoking rates are falling: 58.5% in 1981; 62.0% in 1989; 57.2% in 1990. When the two age groups, 15-34 and 35+ were examined it was found that 60.8% of young Maori women and 5 1.7% of mature maori women were smokers in 1990. Nearly two- thirds of Maori women being regular smokers during the peak child bearing and child rearing years. These statistics suggested that smoking rates among young Maori women are not decreasing and may even be increasing although mature Maori women appear to be either quitting or dying from tobacco use. (Reid and Pouwhare, 1991) European smokers reported a higher average daily consumption of cigarettes than either Maori or Pacific Island Polynesians (Department of Health/Department of statistics, 1992). The Reid and Pouwhare (1991) report that Maori, on average,
23 smoke slightly less than non Maori; 19 per day compared with 22 per day respectively. The N.R.B. survey (1991) found that those of Maori descent were a little less likely than others to accept the dangers of passive smoking exposure. Eight percent of Europeans, 17% of Maori and 30% of Pacific Islanders disagreed that smoking is addictive. Pacific Island people were amongst those who were least likely to see their own smoking as an addiction.
2.6.2.4 Demographic differences 2.6.2.4.1 Age
Smoking incidence has been found to be highest amongst 20-45 year olds (27-29%) (N.R.B., 1991). The decline in cigarette consumption since 1983 has been more marked for older rather than younger age groups (Department of Health/Department of statistics, 1992). Older people are giving up smoking at a greater rate than younger people: 38% of 19-24 group compared with 59% of the 45-64 group; and it has been suggested that the very high proportion of people 65 + who have quit smoking (80%) is probably related to the mortality of smokers (Hillary Commission, 1990). Those aged 45 years or over are also less likely than younger people to believe that there are illnesses caused by smoking and older people (over 55 years) have also been found to be a little less likely than others to accept the dangers of passive smoking exposure (N.R.B., 1991). Those who are least likely to see their own smoking as an addiction are: 15-19 and 55+ year olds. (N.R.B., 1991)
2.6.2.4.2 Socio-economic status It has been found that the more highly educated a person is, the less likely he/she is to smoke cigarettes (Department of Health/Department of statistics, 1992). Indeed male students (73%) and females students (64%) have the highest never smoked rates (Hillary Commission, 1991). Smoking prevalence has been found to be highest amongst unemployed people (49%) of any . employment category status. Unemployed women (55%) are more likely to smoke than unemployed men (45%), with both being more than double any other category. (Hillary Commission, 1990; 1991) Smoking incidence has also been found to be very high amongst blue collar workers (32%) (N.R.B., 1991). Retired people have been found to be amongst the least likely to be smokers. (Hillary Commissions 1990) An inverse relationship between smoking prevalence and socio-economic status (SES 1-2 = high status; SES 4-6 = low status) for both genders was identified by the Life In New Zealand survey. Smoking prevalence was found to increase from
24 upper SES (1-2) 16% to lower SES (4-6) 31% for females; and from upper SES (1- 2)18% to lower SES (4-6) 31% for males. A direct relationship for quitting rates was identified with quitting rates increasing as SES goes up. For males 52% of SES (4-6) quit compared with 65% of SES (1-2); and for females 45% of SES (4-6) quit compared with 61% of SES (1-2). It was suggested that lower prevalence rates and higher quitting rates among higher SES probably reflect a greater willingness of people with higher education to accept recommended health behaviour changes sooner than others. (Hillary Commission, 1991)
2.6.2.4.3 Other Solo parents have the greatest smoking prevalence of all household structure categories (49% for men, 35% for women). Smoking prevalence also been found to be greater among rural males (30%) than urban males (24%), although no such difference has been found for women (Hillary Commission, 1991).
2.6.3 Smoking prevalence amongst New Zealand adolescents A summary of New Zealand smoking statistics for adolescents can be found in table 2.6. Approximately 50 New Zealand children take up smoking every day (Can-Gregg and Gray, 1989). Shaw et al. (1991) surveyed adolescent school children in 1975 and in 1989 and found that overall prevalence of current smokers (those whyo had smoked within the last month) had decreased significantly from 45.6% in 1975 to 33.8% in 1989. Among those who had tried cigarettes, the median age of first smoking was between 10-12 years in both surveys, among both Maori and non Maori. Oei et al. (1990) looked at the smoking behaviour of nine year old children in Dunedin and found that of those who had tried smoking, 18% had tried it in the last year, 6% in the last four weeks, and 3.5% in the last week. When queried about intentions to smoke in the future, 8.3% thought that they would smoke when they got older. Stanton et al. (1991) examined the continuity between smoking at an early age and later smoking behaviour by following a cohort of Dunedin children from age 9 to age 15 years. Children s smoking pattern at age 9 was not found to be highly related to their smoking behaviour at age 15. The children most likely to become daily smokers by age 15 were those who had smoked within the last year at ages 11 and 13. Adolescents who had not smoked by 13 years of age were unlikely to become daily smokers by age 15 years. Oei et al. (1990) concluded that the formative period for children s daily smoking at age 15 was from 10 to 13 years of age.

= = A 1991 Canterbury Area Health Board survey of Christchurch secondary school students (13-17 year olds) revealed that the proportion of adolescents who had tried smoking increased with age. The biggest rise occurred between the third and fourth form age group (approximately 13-14 years) but tended to level off after fourth form. As many as 6% of the total respondents reported smoking more than 20 cigarettes per week. An overwhelming proportion of respondents stated that they did not intend to smoke in the future. Almost half of the respondents (48% female, 43% male) stated that they were bothered by other peoples tobacco smoke and slightly more than this (49% female, 51% male) had actually asked someone not to smoke near them. Devlin. (1991) surveyed fourth form students in South Canterbury using an anonymous questionnaire approach and found that 31 (35.6%) of the daily smokers indicated that they wanted to stop smoking, but only 7 indicated that they wanted help to stop smoking. In 1992, South Canterbury fourth form students were again surveyed and Devlin (1992) found that for those who did smoke, most smoked 1-4 cigarettes a day compared with 5-9 cigarettes in 1991. Fifty-six percent of daily smokers said that they would like to stop smoking, compared with 35% in 1991. When asked whether they thought that they would smoke when they got older, 71% (69%, 1991) said "probably won t/definitely not"; 14% (18%, 1991) said "not sure"; 12% (7%) said "yes" or "probably will". In a survey (Mcleod et al., 1991) of form 1 and 2 Nelson students, 9% reported being regular smokers and 11.5% reported smoking sometimes. Of the total sample, 1.5% reported smoking 2 or more cigarettes per week. Of those who had tried smoking, the highest proportion stated they first tried smokingwhen 7-9 years old (28%). Nearly 12% reported that they first tried smoking before they were 7 years of age. This gives a total of 39% of students experiencing smoking by 9 years of age. McGee and Stanton (1992) surveyed Wellington fourth formers and found that among daily smokers, 70% regarded themselves as "moderate" to "heavy" smokers, while 26% saw themselves as "occasional" or "light" smokers. Over 75% of daily smokers reported trying to quit or cut down on smoking in the last year; only about in every 10 of those trying to quit reported any success. When prevalence of smoking was compared with inprevious research on samples of equivalent age, findings suggested a decrease level of smoking over recent years for both boys and girls. The National Research Bureau surveyed 1600 New Zealand teenagers aged between 10-15 years in 1989 and again in 1991 (N.R.B., 1989; 1991). In 1991 it was found that while only 4% (5% in 1989) were regular smokers, a further 25% said that they had experimented with cigarettes to some degree, most only trying them once. It was found that after age 13 there is a sharp rise in the uptake of regular smoking. Those who smoked regularly, were smoking, on average, about half a packet a week (10.9 cigarettes on average). This figure was slightly lower than the 12.7 average in the 1989 survey. Although around a third of smokers in this group were only smoking 1-5 cigarettes a week, there was another quarter smoking 21 or more a week.

2.6.4 Gender differences II Like the overseas research, New Zealand studies have also found females to be taking up smoking in greater numbers than males (see table 2.7). Stanton et al. (1991) suggest that while there has been a large decrease in the number of boys II who smoke everyday, overall prevalence rates have not changed very much from the 1960s and 1970s due to a large increase in the number of girls who smoke everyday. In a survey of 11-13 year old Nelson students, Mcleod et al. (1991) found II that higher proportions of girls than boys reported having tried smoking at least once in the past and the N.R.B. in 1991 found that girls (5%) were almost twice as likely as boys (3%) to take up a regular smoking habit. II Shaw et al. (1991) surveyed adolescent school children in 1975 and 1989 and found that the prevalence of those who had never smoked had increased from 14.4% to 30.1%, with this trend being highly significant among Maori and non Maori males UI but not evident in female subgroups. They also found that while there were no significant differences in the proportions of male (44.9%) and female (46.4%) current smokers in 1975; there were significantly more female (42.9%) than male (26.2%) current smokers in 1989. II McGee and Stanton (1992) found that for those who smoked daily, boys-smoked an average of 9.7 cigarettes and girls smoked 7.4 cigarettes (non significant II difference). The boys reported that they had been daily smokers for an average of 26 months and girls for an average of 20 months (significant difference). II In a discussion paper by the Ministry of Womens Affairs (1990) it is stated that "Young women between 15 and 25 years of age form the only age group in [II which the numbers of smokers are increasing, and women smokers now outnumber men in the younger age groups. In certain groups such as young Maori women, up to 60% are now smokers II 2.6.5 Ethnic differences II A number of New Zealand surveys have found Maori (especially Maori women) to be more likely to smoke and to smoke greater amounts than the Pakeha and other ethnic groups in New Zealand (see tables 2.8, 2.9, and 2.10). 11 Ree (1986) found that Maori female secondary school students smoked more than any other group; and that Maori respondents (both male and female) smoked more than non Maori respondents. II A survey of 10-15 years in 1989 and 1991 (N.R.B., 1989; 1991) found that experimentation was more likely among Maori than among Europeans or Pacific [II Islanders. Ethnic differences in exposure to passive smoke in the home were also found with 54% of Maori, 39% of Pacific Islanders, and 27% of Europeans reporting that someone had smoked inside their house in their presence on the day U before the survey. While 6% of all young people were found to be exposed to the smoke of three or more others, the figure was 14% for Maori.

31 Shaw et al. (1991) surveyed adolescents in a rural, largely Maori population in 1975 and 1989 and found that the overall prevalence of current smokers had decreased significantly with this decrease being most obvious in those of Maori origin. Maori were found to still smoke more often than non Maori (36.6% vs 25.2%), and this was particularly true of females (46.7% versus 31.3%). Among currently smoking Maori, cigarette consumption was found to have risen significantly (median per week: 15 versus 30), despite an overall fall in the proportion of the groups who reported smoking within the previous month (57.1% versus 36.6%). As a result, there were significantly more smokers in the high consumption group than previously (7.0% versus 12.6%), particularly among Maori females (7.5% versus 16%). McGee and Stanton (1992) found that attempts to quit or cut down on smoking were equally prevalent across the different ethnic backgrounds, suggesting that the characteristics of adolescents who smoke are much the same within different ethnic groups.
2.6.6 Conclusions Significant numbers of New Zealand adolescents are still continuing to initiate and maintain smoking behaviours. It appears that females and Maori are at particular risk prompting the need for prevention programmes to be sensitive to both gender and ethnic differences if any significant changes are to be made to the smoking prevalence rates of New Zealand adolescents.
32 2.7 Why do young adults initiate and maintain smoking behaviours? The smoking onset process may be viewed as a series of stages starting with preparation and anticipation, and moving to initiation, experimentation, and lastly to the maintenance of regular smoking (Best et al., 1988). Cleary et al. (1988) make the point that most adolescents at least experiment with smoking and that it is therefore wrong to neccessarily view initiation as equivalent to the initiation of a long smoking career. Experimenting with smoking does not inevitably lead to the establishment of regular smoking. Cleary et al. suggested that adolescents may go through several cycles of experimentation, regular smoking, and cessation. Hence they suggested that the prevention of any smoking may be futile, but that preventing the transition from experimental smoking to regular smoking may be an attainable and an important goal. It is important to remember too that a correlation between smoking behaviour and other factors does not necessarily indicate a causal relationship. Smoking may be associated with the smoking behaviour of parents and peers but if both smoking by adults and smoking by adolescents are influenced by similar and related environmental factors, then the associations noted may not be of a causal nature. (Cleary et al., 1988)
2.7.1 Correlates of adolescent smoking behaviour Adolescent smoking uptake and maintenance has been associated with a number of factors which can be grouped under eight main headings:
2.7.1.1 Peer group smoking behaviour The individual s peer group and/or peer pressure has been found to be particularly important in the initiation and maintenance of smoking behaviours (Syme and Alcalay, 1982; Gritz, 1984; Reid, 1985; Windom, 1988; Altman et al., 1989; Hynes, 1989; Armstrong et al., 1990; Perry, 1991; Wragg, 1992) Court (1993) stated that:
