摘要：我们调查了中国上海年轻男男性行为者（MSM）中与年长男性伴侣发生性行为（SWOMP）的患病率及其与与男性伴侣无套肛交（CAI）和未被识别的HIV感染的关系。分析样本包括243名18-45岁、HIV阴性或HIV血清状态未知的男男性行为者。年长男性伴侣是指比自己年长10岁以上的男性性伴侣。总体而言，99例（43.0%）和50例（20.7%）报告在生前和过去3个月内分别发生过SWOMP。最近3个月内有男性伴侣的CAI与SWOMP和最近3个月内有稳定男性伴侣的性别独立相关。未被识别的HIV感染与HSV-2阳性、最近3个月内与男性伴侣有任何CAI以及SWOMP独立相关。最近3个月内与稳定男性伴侣的性行为与未被识别的感染也有轻微的显著相关（p = 0.084）。在中国年轻的男男性行为者中，选择年龄较大的伴侣是很普遍的。预防方案应纳入与SWOMP相关的艾滋病毒风险的教育信息。男男性接触者应该被告知，与稳定的伴侣发生不戴避孕套的性行为可能会使他们感染艾滋病毒。
ABSTRACT We examined the prevalence of sex with older male partner (SWOMP) and its association with condomless anal intercourse (CAI) with male partners and unrecognized HIV infection among young men who have sex with men (MSM) in Shanghai, China. The analytic sample included 243 MSM who were 18–45 years and HIV negative or of unknown HIV serostatus. Older male partner refers to male sex partner who was at least 10 years older than themselves. Overall, 99 (43.0%) and 50 (20.7%) reported having SWOMP in lifetime and in the last 3 months, respectively. Having any CAI with male partners in the last 3 months was independently associated with SWOMP and sex with stable male partners in the last 3 months. Unrecognized HIV infection was independently associated with being HSV-2 positive and having any CAI with male partners as well as SWOMP in last 3 months. Sex with stable male partner in the last 3 months was also marginally significantly associated with unrecognized infection (p = 0.084). Older partner selection is common among young MSM in China. Prevention programs should incorporate education messages about the HIV risk associated with SWOMP. MSM should be informed that having condomless sex with stable partners may place them at HIV risk.
