The relationships between school, gender and risk of adolescent pregnancy are also analyzed, and recommendations are made for effective pregnancy prevention programming. The Purral region of Guadalupe on the outskirts of San Jose, Costa Rica, suffers a higher rate of adolescent pregnancy compared to the rest of the country. In response to this problem, the International Health Central American Institute (IHCAI) implemented a sexual health education program in two local secondary schools in 2006. Very little information about the program is available. It is known that the program was initially evaluated through assessments of the participants’ knowledge before and after the educational sessions. There was no evaluation of the youth attitudes or behaviors, adolescent pregnancies, or long- term impact. The author worked with IHCAI in San Jose, Costa Rica to perform an assessment of the longer term effects of this sexual health education program. They developed a questionnaire to evaluate the knowledge, attitudes, and behaviors surrounding sexual health of youth in the Purral community. Researchers at IHCAI later used this survey to collect data from adolescents who had participated in the educational intervention and those who had not. This thesis analyzes the data collected by IHCAI to assess the effectiveness of the - 1 - educational intervention and the influence of other factors on the knowledge, attitudes, and behaviors of adolescents in the Purral region. The thesis begins with an overview of adolescent pregnancy, Costa Rica and the Purral region, and a description of the education intervention implemented by IHCAI. The research goal, logic model, and methods are then described. The results are reported, and the thesis then concludes with discussion of the results as well as study limitations and recommendations for future research and intervention. This thesis will be used to guide IHCAI’s continuation and expansion of adolescent pregnancy prevention programming. - 2 - Background Adolescent Pregnancy: The Problem Childbearing during adolescence is a major issue in public health because of its consequences for young women, their children, their families, and society as a whole. Worldwide, pregnancy and childbirth related deaths are the leading killers of females between the ages of 15 and 19 years.1 The physical process of pregnancy is more dangerous during adolescence than adulthood, with teenage mothers at an increased risk for preeclampsia as well as obstructed labor. 2 Prolonged labor can lead to death or permanent disability from obstetric fistula, and because adolescents are also less likely to have a skilled birth attendant present during delivery, the risk of these complications is further increased. 3 In addition, over 2.2 million adolescents undergo illegal and unsafe abortions each year which puts them at risk for infection, future fertility problems, and death. 4 Not only are the adolescents themselves at risk, but infants born to adolescent mothers have a higher risk for low birth weight, SIDS, accidents, and hospitalization in the first year of life.5 The social impact of childbearing during adolescence is also considerable, as these mothers are more likely to be single parents, to have greater numbers of children overall, and to earn less income and attain less education than women who delay childbearing until age 20 or later.6 Furthermore, adolescent mothers are at high risk for dysfunctional maternal-infant attachment, which puts the child at greater risk for long term psychological dysfunction.7 Carol Buvinic - 3 - found in her research in Chile, Barbados, Guatemala and Mexico that a dichotomy exists between poor and non-poor teenage mothers. Poor women who became pregnant during adolescence had lower income over their lifetime than poor women who delayed childbearing, yet no income difference exists for non-poor women regardless of when they first became pregnant. Adolescent pregnancy, therefore, serves to entrench poverty by limiting already poor women’s incomes. Furthermore, low socioeconomic status is a known risk factor for adolescent pregnancy,8 creating a vicious cycle. Global Epidemiology Worldwide, the average rate of births per 1000 females age 15-19 years is 65.9 This figure varies significantly depending upon region; see Table 1 below for a list of selected regions and countries.

In a 2004 discussion paper on adolescent pregnancy, the World Health Organization described the following associations.11 Poverty is universally related to higher rates of adolescent pregnancy. In the United States this translates to greater incidence of teen pregnancy in minority populations, as they are more often poor. In many countries young age at marriage
