Implementing Adolescent Reproductive Health Programmes in Nigerian Cities: Longitudinal Changes in Knowledge, Attitudes, and Behaviors

Adolescent reproductive health (ARH) programmes in Nigeria have been implemented to improve knowledge, attitudes, and behaviors related to sexual health among young people. The study employed a longitudinal qualitative approach using participant observation, interviews, and focus group discussions in urban settings across Nigeria. Data collection occurred over three years, capturing pre-, mid-, and post-programme phases. During the follow-up phase, participants demonstrated significant improvement in knowledge about contraception methods (increased from 40% to 75%) and reduced intentions for early sexual activity (decreased by 25%). ARH programmes have successfully enhanced adolescent reproductive health literacy over time. Continued support is recommended to sustain these positive changes, particularly in marginalized communities where access remains limited.
