The long-term effects of reproductive health education among primary and secondary school students: a longitudinal quasi-experimental study in rural Tanzania.

Background: Adolescent pregnancy remains a major global health issue, increasing the risk of complications during pregnancy and childbirth in mothers and babies. In Tanzania, adolescent pregnancy threatens girls' education and makes it difficult for them to obtain a proper job; hence, the majority fall into poverty. Previous studies have developed and conducted reproductive health education for adolescent students; however, they evaluated only the effect immediately after education. Therefore, this study investigated the effects of reproductive health education on attitudes and behaviors toward reproductive health among adolescent girls and boys one year after the intervention in rural Tanzania. Methods: A longitudinal quasi-experimental study was conducted with 3295 primary and secondary students (2123 in the intervention group, 1172 in the control group) from three purposefully selected wards in Korogwe District. In the intervention group, the students received reproductive health education. We used paper-based questionnaires to evaluate the effect of the adolescent education program on attitudes and behaviors toward reproductive health education. To analyze the association between the intervention and each outcome, mixed-effect multiple regression analyses was conducted. Results: The mean age, primary school proportion, and female proportion of the intervention and the control group was 13.05 (standard deviation (SD) 1.59), 14.14 (SD 1.7), 77.9% and 34.3%, and 54.2% and 52.6%, respectively. There was no statistically significant effect of reproductive health education on adolescent health attitudes and behaviors in the multiple regression analyses (coefficient: − 0.24 (95% confidence interval (CI): − 0.98 to 0.50), coefficient: 0.01 (95%CI: − 0.42 to 0.43)). Conclusion: A statistically significant effect of reproductive health education on adolescent health attitudes and behaviors was not found. An effective reproductive health education intervention to improve the attitude and behaviors of reproductive health among Tanzania adolescents in the long term remain to be determined, particularly in real-world settings. Trial registration The National Institute for Medical Research, Tanzania (NIMR/HQ/R.8a/Vol. IX988). Plain Language Summary: Adolescent pregnancy increases the risk of complications during pregnancy and childbirth, which could cause death among 15–19-year-old girls. In Tanzania, one in four adolescents aged 15–19 began childbearing. However, there is no officially recognized curriculum for reproductive health in schools. Additionally, cultural and traditional norms prevent parents from discussing sexuality with their children. A solution to this issue is for a third party, such as a non-profit organization, to provide adolescents with adequate reproductive health education in schools. Previous studies have developed and evaluated a reproductive health education program and found significant effects on improved knowledge and behavior among adolescent girls and boys immediately after the intervention. This study examined the effects of reproductive health education on adolescents' attitudes and behavior toward reproductive health one year after the intervention in rural Tanzania. We could not find a statistically significant effect of reproductive health education on adolescents' attitudes and behavior during a one-year period in the multiple regression analyses. These results could have been influenced by the location of the intervention, contents, period of evaluation, and other potentially unknown factors. [ABSTRACT FROM AUTHOR]
