The effects of peer education on STD and AIDS knowledge among prisoners in Mozambique.

The study was designed to evaluate the impact of education on AIDS knowledge among prison inmates in Maputo, Mozambique. A 6-month follow-up study was carried out in 1993 among 300 prisoners. A knowledge, attitudes, and practices questionnaire regarding AIDS and STD was administered to each subject as part of the intake medical examination and after an educational intervention provided by 30 prisoner 'activists'. A large proportion of prisoners had high risk behaviours (65% had 2 or more sexual partners per month and 39% had a history of STD) and low AIDS knowledge at incarceration. Statistically significant increases in knowledge occurred after the intervention. Prisoners with less formal education had a poorer performance on the initial questionnaire (43% vs 69% P < 0.00001) and had a greater improvement after the intervention (41% vs 24%, P < 0.00001). The results demonstrate that educational interventions involving peer health educators contribute positively to the acquisition of knowledge among prisoners.
