Effect of a context-specific health education intervention on knowledge of health risk behaviors among adolescents in Nigerian public and private secondary schools: a comparative study

The CsHEI improved knowledge of in-school adolescents in public- and private-owned secondary schools in Osun state, Nigeria in all domains of HRBs. Integrating the CsHEI with other health behavioral change strategies can mitigate prevalence of HRBs among adolescents, thereby improving health-outcomes and well-being of adolescents.
