We sought to learn what factors are associated with anal intercourse among adolescents and young adults. We examined demographic, behavioral, relationship context, attitudinal, substance use, and mental health correlates of recent heterosexual anal intercourse among adolescents and young adults who reported engaging in recent unprotected sex.
Among 1348 at-risk adolescents and young adults aged 15 to 21 years in 3 US cities, we assessed sexual risk behavior with each sexual partner in the past 90 days. Data were collected from 2000 to 2001.
Recent heterosexual anal intercourse was reported by 16% of respondents. Females who engaged in anal intercourse were more likely to be living with a sexual partner, to have had 2 or more partners, and to have experienced coerced intercourse. For males, only a sexual orientation other than heterosexual was a significant predictor of engaging in heterosexual anal intercourse.
Our findings document the prevalence of heterosexual anal intercourse among adolescents and young adults who had recent unprotected sex. Among females, the variables associated with anal intercourse relate to the context and power balance of sexual relationships. Different influences for males and females suggest different foci for interventions.
我们试图了解哪些因素与青少年及年轻成年人中的肛交行为相关。我们研究了报告近期有过无保护性行为的青少年及年轻成年人中，近期异性肛交行为在人口统计学、行为、关系背景、态度、物质使用及心理健康方面的相关因素。
在美国3个城市的1348名年龄在15至21岁的高危青少年及年轻成年人中，我们评估了他们在过去90天内与每个性伴侣的性风险行为。数据收集于2000年至2001年。
16%的受访者报告近期有过异性肛交行为。进行肛交的女性更有可能与性伴侣同居，有过2个或更多性伴侣，且经历过强迫性交。对于男性而言，只有非异性恋的性取向是进行异性肛交行为的显著预测因素。
我们的研究结果记录了近期有过无保护性行为的青少年及年轻成年人中异性肛交行为的流行情况。在女性中，与肛交行为相关的变量与性关系的背景及权力平衡有关。男性和女性受到的不同影响表明干预措施应针对不同重点。
