Impact Analysis of School-Based Adolescent Sexual and Reproductive Health Programmes in Dar es Salaam, Tanzania: A Longitudinal Comparative Study

Adolescent sexual and reproductive health (ASRH) in Dar es Salaam, Tanzania, is a critical public health concern. Despite government initiatives, there remains a high prevalence of risky behaviors among adolescents. A longitudinal comparative study was conducted using data from two cohorts (baseline and follow-up) recruited from the same schools. Participants completed surveys assessing sexual behaviour, knowledge, and attitudes towards ASRH. The proportion of students who engaged in risky sexual behaviors decreased by 30% over a three-year period following programme implementation. School-based ASRH programmes significantly reduced risky sexual behaviors among Tanzanian adolescents, highlighting their potential as effective public health interventions. Policy-makers should prioritise the expansion and sustainability of these programmes to further reduce adolescent risk behaviors in Tanzania.
