BACKGROUND
Adolescent sexual debut and non-consensual sex have been linked to higher sexual risk and STI infection in adulthood among men who have sex with men (MSM) in high-income countries. This study aimed to examine adolescent and non-consensual anal sexual debut among Chinese MSM and to evaluate factors associated with adolescent sexual debut and non-consensual anal sex.
METHODS
A cross-sectional study was conducted recently among Chinese men assigned male sex at birth, ≥18 years old, and who had ever engaged in anal sex with a man. Participants answered questions regarding socio-demographics, condomless sex, age at anal sexual debut with a man, and whether the first anal sex was consensual. Factors associated with an adolescent sexual debut (< 18 years old) and non-consensual sex at sexual debut were evaluated. We defined adolescent sexual debut as having anal sex with another man at 17 years old or younger, and the participants were asked whether their first male-to-male anal sex was non-consensual.
RESULTS
Overall, 2031 eligible men completed the survey. The mean age of sexual debut was 20.7 (SD = 4.3) years old. 17.6% (358/2031) of men reported adolescent sexual debut, and 5.0% (101/2031) reported a non-consensual sexual debut. The adolescent sexual debut was associated with having more male sexual partners (adjusted OR 1.10, 95% CI 1.06-1.15) and condomless anal sex in the last three months (AOR = 1.71, 95% CI 1.34-2.18). MSM whose sexual debut was non-consensual were more likely to have condomless anal sex (AOR = 1.76, 95% CI 1.17-2.66), and to have reported an adolescent sexual debut (AOR = 2.72, 95% CI 1.75-4.21).
CONCLUSIONS
Many Chinese MSM reported adolescent sexual debut and non-consensual sex, both of which are associated with sexual risk behaviors and drive STI transmission. These findings highlight the need for designing tailored interventions for MSM who experienced adolescent sexual debut and non-consensual sex at debut.
背景
在高收入国家，青少年初次性行为和非自愿性行为与男男性行为者（MSM）成年后的性风险和性传播感染（STI）有关。本研究旨在研究中国 MSM 的青少年和非自愿肛交初次性行为，并评估与青少年初次性行为和非自愿肛交相关的因素。
方法
最近在中国进行了一项横断面研究，研究对象为出生时被分配为男性、年龄在 18 岁及以上、曾与男性发生过肛交的男性。参与者回答了关于社会人口统计学、无保护性行为、与男性发生肛交的年龄以及第一次肛交是否自愿的问题。评估了与青少年初次性行为（<18 岁）和初次性行为非自愿相关的因素。我们将青少年初次性行为定义为与另一名男性在 17 岁或以下发生肛交，参与者被问及他们的第一次男男性交是否非自愿。
结果
共有 2031 名符合条件的男性完成了调查。初次性行为的平均年龄为 20.7（SD=4.3）岁。17.6%（358/2031）的男性报告有青少年初次性行为，5.0%（101/2031）报告有非自愿初次性行为。青少年初次性行为与有更多的男性性伴侣（调整后的 OR 1.10，95%CI 1.06-1.15）和最近三个月无保护肛交（AOR=1.71，95%CI 1.34-2.18）相关。初次性行为非自愿的 MSM 更有可能发生无保护肛交（AOR=1.76，95%CI 1.17-2.66），并且更有可能报告青少年初次性行为（AOR=2.72，95%CI 1.75-4.21）。
结论
许多中国 MSM 报告了青少年初次性行为和非自愿性行为，两者都与性风险行为和性传播感染（STI）的传播有关。这些发现强调需要为经历青少年初次性行为和初次性行为非自愿的 MSM 设计有针对性的干预措施。
