To determine the prevalence of sexual initiation and the contraceptive practices of adolescents in the tri-border area between the cities of Foz do Iguaçu (Brazil), Ciudad del Este (Paraguay), and Puerto Iguazú (Argentina).
A cross-sectional study was conducted with 2 788 adolescents from public schools (age 12 to 18 years). Information was obtained through questionnaires administered in the schools between 2012 and 2013. The prevalence of sexual initiation, contraceptive practices, and sociodemographic variables was analyzed. To verify the association between the studied variables, the chi-square test was used with a significance level of 5%.
The overall prevalence of sexual initiation among adolescents was 34.6% (Puerto Iguazú: 45.3%; Foz do Iguaçu: 35.2%; Ciudad del Este: 23.3%). The prevalence of sexual initiation was higher in males and in the 15-16 year age range. Sexual initiation was associated with sex, age, schooling, and school shift (morning, afternoon, or evening). Having received information on contraceptives was associated with sex, age, schooling, and contraceptive use in all three cities/countries. Adolescents of both sexes had received information about contraceptives, especially from the family and the school.
It is suggested that municipalities/countries seek to structure a tri-national border policy with intersectoral programs and projects in order to promote educational practices regarding sexual and reproductive health for adolescents.
确定位于（巴西）伊瓜苏港、（巴拉圭）东方市和（阿根廷）伊瓜苏港三城市边境地区青少年的性初次体验发生率及避孕措施使用情况。
对来自公立学校的2788名青少年（年龄在12至18岁之间）开展了一项横断面研究。2012年至2013年期间通过在学校发放问卷获取信息。分析了性初次体验发生率、避孕措施使用情况及社会人口统计学变量。为验证所研究变量之间的关联，采用了显著性水平为5%的卡方检验。
青少年中性初次体验的总体发生率为34.6%（伊瓜苏港：45.3%；伊瓜苏市：35.2%；东方市：23.3%）。男性及15 - 16岁年龄组的性初次体验发生率更高。性初次体验与性别、年龄、受教育程度及学校班次（上午、下午或晚上）相关。在所有三个城市/国家，接受避孕知识与性别、年龄、受教育程度及避孕措施使用相关。两性青少年均接受过避孕知识，尤其是来自家庭和学校的。
建议各市/各国设法构建一项三边边境政策，实施跨部门计划和项目，以促进针对青少年性健康和生殖健康的教育实践。
