Adolescent sexual health knowledge is crucial in Southern Ghana's schools, where gender-based violence (GBV) affects young people disproportionately. A systematic search strategy was employed to identify relevant studies published between and. Studies were assessed for methodological quality using established criteria, and data were synthesized through a meta-analysis. Meta-analysis revealed an average effect size of r = 0. 35 (95% CI: 0. 28, 0. 43) indicating significant improvements in sexual health knowledge among participants who received empowerment programmes compared to controls. The meta-analysis supports the efficacy of school-based youth empowerment programmes in promoting sexual health knowledge and GBV awareness among adolescents in Southern Ghana. Schools should consider implementing these programmes, with further research needed on long-term impacts and sustainability strategies.
Adjei et al. (2005) studied this question.
