Age at sexual debut is an important determinant of HIV infection. The paper investigates the effects of age at sexual debut on sexual behaviour among South African youth. Among 2 875 respondents who ever had sexual intercourse, 39% had early sexual debut (sexual debut at age 16 years and below). Males (44.6%) were significantly more likely than females (35.1%) to report early sexual debut (odds ratio (OR) = 1.45, p-value < 0.001). Multiple sexual partners are significantly more common among those that had early sexual debut (10.4% vs. 4.8%) than those who had late sexual debut, (OR = 2.29, p-value < 0.001). Those aged 15 to 19 years were 1.4 times more likely to report multiple partners compared to those aged 20 to 24 years. Delaying sexual debut is a strategy many national programmes are promoting. The results of this study provide additional arguments to support such initiatives and show the need to strengthen intervention targeting youth.
首次性行为的年龄是感染艾滋病毒的一个重要决定因素。本文调查了首次性行为的年龄对南非青年性行为的影响。在2875名有过性行为的受访者中，39%的人初次性行为较早（16岁及以下发生首次性行为）。男性（44.6%）报告初次性行为较早的可能性显著高于女性（35.1%）（比值比（OR）=1.45，p值<0.001）。初次性行为较早的人（10.4%对4.8%）中，多个性伴侣的情况明显比初次性行为较晚的人更常见（OR=2.29，p值<0.001）。与20至24岁的人相比，15至19岁的人报告有多个性伴侣的可能性高1.4倍。推迟初次性行为是许多国家项目正在推广的一项策略。本研究结果为支持此类举措提供了更多论据，并表明有必要加强针对青年的干预措施。
