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.
本研究旨在比较巴西圣保罗市公立和私立学校青少年对性传播感染/艾滋病（STDs/AIDS）的了解情况，并确定与充分了解以及持续使用男用避孕套相关的因素。我们选取了13所公立学校和5所私立学校的1594名年龄在12至19岁之间的青少年，让他们填写一份关于性传播感染/艾滋病知识及男用避孕套使用情况的问卷。计算患病率比值及95%置信区间。性传播感染知识得分采用对应50%正确答案的截断点。统计检验采用卡方检验和泊松多元回归。私立学校男用避孕套的持续使用率为60%，公立学校为57.1%（p>0.05），且与男性性别和较低的社会经济地位相关。女性性别、较高的受教育程度、就读私立学校、白种人种族以及单身与对性传播感染的较高了解相关。公立和私立学校的青少年对性传播感染预防有充分了解，但这不包括采取有效的预防措施。应扩大教育项目及性传播感染/艾滋病宣传活动，以尽量减少易感性。
