In the majority of communities, HIV programs were incorporated into festivals (78%), the PSABH program had been presented at the primary school (63%), condoms were available to pupils (70%) and community leaders identified at least one cultural practice or social event that contributed to students' vulnerability (79-80%).
At the community level, youth of both sexes who attended schools that received the PSABH program were less likely to report sexual debut than were youth who did not (odds ratios, 0.8-0.9).
Among both sexes, sexual debut was delayed among youth who lived in communities where AIDS deaths were publicly acknowledged (odds ratios, 0.6-0.8) or who attended schools where the PSABH program had been presented (0.8-0.95).
We found, for instance, that youth (particularly females) in schools with the PSABH program initiated sex at a later age than other youth.
In this study, the presence of teachers trained to deliver HIV education in schools (via the PSABH program) was associated with delayed sexual debut, supporting the decision by the Kenyan Ministry of Education to expand such programming to every school in the country.
