title: [Factors associated with condom use and knowledge about STD/AIDS among teenagers in public and private schools in São Paulo, Brazil].
abstract: This study aimed to compare knowledge about STD/AIDS and identify the factors associated with adequate knowledge and consistent use of male condoms in teenagers from public and private schools in the city of São Paulo, Brazil. We selected 1,594 adolescents ranging 12 to 19 years of age in 13 public schools and 5 private schools to complete a questionnaire on knowledge of STD/AIDS and use of male condoms. Prevalence ratios were computed with a 95% confidence interval. The score on STD knowledge used a cutoff point corresponding to 50% of correct answers. Statistical tests were chi-square and Poisson multiple regression. Consistent use of male condoms was 60% in private and 57.1% in public schools (p > 0.05) and was associated with male gender and lower socioeconomic status. Female gender, higher schooling, enrollment in private school, Caucasian race, and being single were associated with higher knowledge of STDs. Teenagers from public and private schools have adequate knowledge of STD prevention, however this does not include the adoption of effective prevention. Educational programs and STD/AIDS awareness-raising should be expanded in order to minimize vulnerability.
