This paper describes an evaluation of possible changes in sexual behavior in adolescents who participated in a school-based sex education program in selected public schools in four municipalities in the state of Minas Gerais, Brazil. The program is inserted within the context of reproductive rights, deals with risks involved in unsafe sexual practices and focuses on the positive aspects of sexuality. A quasi-experimental design with pre and post-tests and a non-equivalent control group was used to evaluate the intervention. A total of 4,795 questionnaires were included in this analysis. The program succeeded in more than doubling consistent condom use with casual partners and in increasing the use of modern contraceptives during last intercourse by 68%. The intervention had no effect on age at first intercourse or on adolescents' engagement in sexual activities. The sex education program was effective in generating positive changes in the sexual behavior of adolescents, while not stimulating participation in sexual activities.
本文描述了对巴西米纳斯吉拉斯州四个市部分公立学校参加校内性教育项目的青少年性行为可能发生的变化进行的评估。该项目处于生殖权利背景下，涉及不安全性行为所带来的风险，并侧重于性方面的积极层面。采用了带有前后测试以及非等效对照组的准实验设计来评估该干预措施。本分析共纳入4795份问卷。该项目成功使与临时伴侣始终坚持使用避孕套的比例增加了一倍多，并使上次性交时现代避孕方法的使用增加了68%。该干预措施对首次性交的年龄或青少年参与性活动没有影响。性教育项目有效地促使青少年性行为产生积极变化，同时并未刺激他们参与性活动。
