This study sought to investigate the prevalence of sexual intercourse among adolescents in a Brazilian city and its association with sociodemographic factors, health-risk behaviors, and body image perception. A cross-sectional study was conducted using data from the National Adolescent School-based Health Survey (PeNSE), carried out in 2009. The sample comprised schoolchildren enrolled in the 9th year in the city of Goiânia, Goiás (n= 3,099), mostly aged between 13 and 15. The dependent variable was the reporting of sexual intercourse at least once. To identify variables associated with sexual activity, Poisson regression analysis was used. The prevalence of sexual intercourse at least once in the adolescents' lifetime was 26.5% (95% CI= 23.8-29.4). Prevalence was higher among males, those aged 14 years or older, who reported not living with their mother or with their father, who attended public schools, reported alcohol, tobacco or other drug use, and were involved in fights and family violence. The conclusion reached was that the prevalence of sexual intercourse was high and associated with poor sociodemographic conditions, health-risk behaviors and violence. These factors should be considered in the health promotion strategies seeking more safe and healthy sexual behavior during adolescence.
本研究旨在调查巴西一个城市青少年的性交发生率及其与社会人口学因素、健康风险行为和身体形象认知之间的关联。采用2009年开展的全国青少年学校健康调查（PeNSE）的数据进行了一项横断面研究。样本包括戈亚斯州戈亚尼亚市九年级的在校学生（n = 3099），大多数年龄在13至15岁之间。因变量是至少有过一次性交的报告。为了确定与性活动相关的变量，使用了泊松回归分析。青少年一生中至少有过一次性交的发生率为26.5%（95%置信区间= 23.8 - 29.4）。在男性、14岁及以上者、报告未与母亲或父亲同住者、就读于公立学校者、报告有饮酒、吸烟或其他吸毒行为者以及卷入打架和家庭暴力者中，发生率较高。得出的结论是，性交发生率很高，且与不良的社会人口学状况、健康风险行为和暴力行为相关。在寻求促进青少年更安全、健康性行为的健康促进策略中，应考虑这些因素。
