Latin America attempts to tackle : the process, results, push backs and future challenges

Centro de Investigación en Nutrición y Salud, Summary Instituto Nacional de Salud Pública, Mexico’s obesity prevalence is one of the world’s highest. In 2006, academics, and Cuernavaca , México federal and state government agencies initiated efforts to design a national policy for obesity prevention. The Ministry of Health (MOH) established an expert Received 13 August 2013; accepted 14 panel to develop recommendations on beverage intake for a healthy life in 2008.

Bold strategies currently under consideration include taxation of sugar-sweetened beverages, improvement of norms for healthy food in schools, regulation of food and beverage marketing to children and implementation of a national front-of-pack labeling system. Strong civil society organizations have embraced the prevention of obesity as their goal and have used evidence from academia to position obesity prevention in the public debate and in the government agenda.

Table 1 The obesity problem in Mexico, nutrition transition–related factors, and opportunities for action

A. Characteristics of obesity in Mexico identified from surveys and mortality registries

1. Obesity is a highly prevalent health problem in all regions, age groups, and genders in Mexico (31). 2. The increasing obesity prevalence trends in 1999–2006 were among the highest documented in the world (32). However, between 2006 and 2012, this trend increased at a lower rate, probably because of a saturation of susceptible population effect (33). 3. Obesity’s prevalence is increasing at more alarming rates in the most vulnerable populations, such as those living in poverty and children (34). 4. Mortality associated with obesity is a significant percentage of the total national mortality (12.2%) (35). 5. The generalized obesity problem appeared in Mexico before the undernutrition problem was solved, and they still coexist. Undernutrition still affects important sectors of the country (36). 6. Obesity coexists with undernutrition within the most vulnerable communities of the country, within households, within families, and even within individuals (e.g. obesity with iron deficiency) (37). 7. Health expenditure is increasing at a significant rate because of obesity, and even small reductions in the prevalence of this condition would mean notable savings to the country (38).

B. Changes in the Mexican diet associated to the nutrition transition

1. Increase in the availability of low-cost processed foods with high quantities of sugar, fat and sodium (8). 2. Increase in fast food consumption and food consumption outside the home for a growing sector of the population (39). 3. Decrease in available time for food preparation (8). 4. Significant increase in exposure to food and beverage marketing and to technology that decreases physical activity (40). 5. Increase in per capita income (38). 6. Increase in the availability and supply of ready-to-eat foods and processed foods in general (41).

C. Identified opportunities for action that could contribute to obesity prevention policies

1. Mexico is among the countries with the highest consumption of caloric beverages in the world. Caloric beverages contribute 20–23% of the total energy intake in the population (14,15). 2. Children spend only a few hours at school (about 4.5 h per day), but they have many opportunities to eat unhealthy energy-dense foods while there (42). 3. Food and beverage marketing to young children is not regulated to protect this vulnerable sector of the population (43). 4. Nutrition literacy is poor among the general population. Current labeling schemes are not useful, and the current Guideline Daily Amounts are confusing and misleading. There is a clear need for a labeling system that promotes better nutritional choices for the population (44). 5. Physical activity is very low across the country. Physical inactivity prevalence has increased since 2006 (45).

Table 3 Recommendations for an effective policy

1. Address explicitly not only the basic causes of obesity, but also the ones related to an obesogenic environment as part of a policy specifically designed to improve nutrition and physical activity in the population across all age groups. 2. Consider the ANSA as a part of the National Development Plan, provide a budget and a plan for follow-up able to transcend administrative changes with an intersectoral commission, and create a forum with food industry oversight. 3. Achieve adequate coordination of the government sectors at the federal, state, and local levels and with civil society. The ANSA represents a good attempt to coordinate government efforts and could become a good model if a budget is assigned and instruments to monitor goals and accountability are implemented. 4. Develop a system to monitor results, the activities of the government, and compliance with the regulations by the food industry and to review periodically the ANSA commitments and their correct implementation. 5. Assure that all prevention programmes include actions during the first years of life, a window of opportunity to decrease the risk of obesity, and address all socioeconomic groups and geographic regions. 6. Assure that the prevention programme designs consider social and cultural factors that influence behavior to achieve a high utilization of health services and adoption of healthy food and physical activity habits. 7. Develop a norm to regulate food and beverage marketing to children and adolescents. This is a crucial issue in obesity prevention and should not be a self-regulatory code. Marketing strategies can influence adoption of unhealthy food patterns that might impact health throughout the life cycle. 8. Develop a healthy diet–promotion strategy through nutritional education and other actions to recover and preserve traditional culinary roots. 9. Develop a single national voluntary front-of-package labeling system that is easy for the population to understand, in particular the poor and that orients the public towards healthier food choices.
