Condom use at sexual debut is associated with subsequent condom use and with decreased risk of sexually transmitted infections. There is a dearth of data on determinants of condom use at first sexual intercourse. We aimed to determine factors associated with condom use at first sexual intercourse before marriage among Vietnamese adolescents and youths.
The study involved the analysis of data from the Survey Assessment of Vietnamese Youth, 2003, the first nationally representative survey of young people in Vietnam. The survey included 7584 adolescents and youths aged 14-25 years. In this study, data of 605 adolescents and youths who had engaged in premarital sex were analyzed for factors associated with condom use using descriptive analyses, and regression techniques, allowing for sampling weights, clustering and stratification.
Of 605 adolescents and youths who had engaged in premarital sex, 28.6% reported condom use at first sexual intercourse. Condom use at sexual debut was less common in females than males [odds ratio (OR)=0.15; 95% confidence interval (95% CI)=0.07-0.30] and less common in those who experienced peer pressure to engage in social higher risk behaviors (OR=0.57; 95% CI=0.32-0.99). Condom use was more common if a friend/acquaintance or a stranger/sex worker was the first sexual partner (OR=2.20; 95% CI=1.16-4.17 and OR=17.90; 95% CI=6.88-46.54) respectively, each compared with fiancé/boyfriend/girlfriend as first sexual partner.
These data suggest that approximately one in three unmarried Vietnamese youths used a condom at first sexual intercourse. Gender, peer pressure and the nature of the relationship to the first sexual partner were independently associated with condom use. These results can inform programs directed at preventing HIV and other sexually transmitted infections among young Vietnamese.
首次性行为时使用避孕套与后续使用避孕套以及降低性传播感染风险相关。关于首次性交时使用避孕套的决定因素的数据匮乏。我们旨在确定越南青少年和青年婚前首次性交时使用避孕套的相关因素。
该研究涉及对2003年越南青年调查评估数据的分析，这是越南首次具有全国代表性的年轻人调查。该调查包括7584名14 - 25岁的青少年和青年。在本研究中，对605名有婚前性行为的青少年和青年的数据进行分析，使用描述性分析和回归技术来确定与使用避孕套相关的因素，同时考虑抽样权重、聚类和分层。
在605名有婚前性行为的青少年和青年中，28.6%报告在首次性交时使用了避孕套。首次性行为时使用避孕套在女性中比男性中更不常见[优势比（OR）=0.15；95%置信区间（95%CI）=0.07 - 0.30]，在那些经历同伴压力而参与社会高风险行为的人中也更不常见（OR = 0.57；95%CI = 0.32 - 0.99）。如果朋友/熟人或陌生人/性工作者是第一个性伴侣，使用避孕套则更为常见（分别为OR = 2.20；95%CI = 1.16 - 4.17和OR = 17.90；95%CI = 6.88 - 46.54），与第一个性伴侣是未婚夫/男友/女友相比。
这些数据表明，大约三分之一的未婚越南青年在首次性交时使用了避孕套。性别、同伴压力以及与第一个性伴侣关系的性质与使用避孕套独立相关。这些结果可为旨在预防越南年轻人中艾滋病毒和其他性传播感染的项目提供参考。
