How would you determine their effects on female adolescent reproductive health outcomes like teenage pregnancy, STIs, illegal abortions, etc. Any advice?
Possibly compare schools with health programs and those without and follow up for incidence of female ARH outcomes? Your challenge will be measurement of the outcomes, though
Please check this publication Brieger, W.; Delano, G., Lane, C., Oladimeji, O. and Oyediran, K. (2001) “West African Youth Initiative: Outcome of a Reproductive Health Education Program,” Journal of Adolescent Health, 29:436-446. The paper examine the outcome of program intervention (peer education) on knowledge of reproductive health among adolescents. It may be a starting point.
