To examine the distribution of and factors associated with event-level heterosexual anal sex and of event-level condom use during anal sex among adolescent women.
Adolescent women (N=387; age 14-17 years at enrollment) were recruited from primary care clinics for a longitudinal cohort study of sexually transmitted infections and sexual behavior. Data were taken from daily sexual diaries; generalized estimating equation logistic regression assessed the likelihood of anal sex or condom use during anal sex on a given day.
Heterosexual anal intercourse is a small but nonrandom event-level component in adolescent women's sexual behavior. About 30% of anal sex events were condom protected. Mood, partner, and situational factors predicted anal sex, but not condom use during anal sex; within-day and recent behavior factors were the strongest influences on both outcomes.
Our findings suggest the importance of providers' screening adolescent women patients during office visits about anal sex and about condom use during anal sex, as well as asking questions about the context of these behaviors to appropriately tailor risk reduction counseling.
研究青少年女性性行为中肛交事件层面的异性肛交分布情况和相关因素,以及肛交事件中使用安全套的情况。
从初级保健诊所招募了 387 名青少年女性(入组时年龄为 14-17 岁),进行性传播感染和性行为的纵向队列研究。数据来自每日性行为日记;广义估计方程逻辑回归评估了特定日期发生肛交或肛交中使用安全套的可能性。
异性肛交是青少年女性性行为中一个较小但非随机的事件层面组成部分。约 30%的肛交事件有安全套保护。情绪、伴侣和情境因素预测了肛交,但不能预测肛交中使用安全套的情况;当日和近期的行为因素对这两个结果的影响最大。
我们的研究结果表明,医生在门诊时询问青少年女性患者关于肛交和肛交中使用安全套的情况,并询问这些行为的背景,以适当调整风险降低咨询,这非常重要。
