摘要目的 了解年轻男男性行为者(young men who have sex with men ,YMSM)rush poppers(以下简称rush)使用现状,分析影响因素。 方法 2016年9月—2019年9月,用“滚雪球”抽样法,在绵阳市进行YMSM rush使用和血清学的现况调查,用χ2检验,logistics回归分析rush使用的影响因素。 结果 336名YMSM的rush使用率24.1%,使用时间中位数为4.5(2.0,12.0)个月,42.0%因好奇、29.6%因减少肛交疼痛、27.2%因寻求刺激使用,81.5%与固定性伴、28.4%与偶遇性伴共用,使用后30.8%发生无保护肛交。rush使用的 HIV-1阳性率12.3%,高于未使用的2.0%(χ2=15.544,P＜0.001)。多因素分析发现,职业非学生(OR=1.992,95%CI:1.036～3.831)、知晓艾滋病知识(OR=2.617,95%CI:1.235～5.545)、有风险认识(OR=4.407,95%CI:1.220～15.918)、近6个月有商业性行为(OR=9.136,95%CI:1.228～67.985)、近6个月肛交人数增加(OR=1.732,95%CI:1.170～2.563)的rush使用可能更大,近1年接受宣传材料发放(OR=0.410,95%CI:0.203～0.825)、近1次肛交有保护(OR=0.346,95%CI:0.152～0.785)的rush使用可能更小。 结论 YMSM其rush使用较普遍,好奇是主要原因,与固定性伴共用常见。rush使用增加其高危性行为和HIV感染风险,应针对性加强健康教育。
Abstract：Objective To understand the current status of use of rush poppers (hereinafter referred to as rush) among young men who have sex with men (YMSM), and to analyze its influencing factors. Methods From September 2016 to September 2019, using the snowball sampling method, the current status of rush use and serology among YMSM in Mianyang City was surveyed. χ2 test and logistic regression analysis were employed to identify factors influencing rush use. Results The usage rate of rush in 336 YMSM was 24.1%, and the median usage time was 4.5 (2.0, 12.0) months. 42.0% of the YMSM were due to curiosity, 29.6% pain reduction during anal sex, and 27.2% stimulation. 81.5% used rush with fixed partners, and 28.4% shared rush with occasional partners. 30.8% of the YMSM had unprotected anal sex after using such. The HIV-1 positive rate was higher in rush users than in non-users(12.3% vs. 2.0%, χ2=15.544, P<0.001). Multivariate analysis revealed that non-students(OR=1.992, 95%CI:1.036-3.831), YMSM having HIV/AIDS knowledge(OR=2.617, 95%CI:1.235-5.545), YMSM with risk awareness(OR=4.407, 95%CI:1.220-15.918), YMSM having commercial sex in the past 6 months(OR=9.136, 95%CI:1.228-67.985), YMSM with an increase in the number of anal sex partners in the past 6 months (OR=1.732,95%CI:1.170-2.563) had a greater possibility to use rush. YMSM accepting the distribution of promotional materials in the past year (OR=0.410, 95%CI:0.203-0.825) and YMSM with protection during the last anal sex (OR=0.346,95%CI:1.152-0.785) were less likely to use rush. Conclusion Rush use is prevalent among the YMSM. Curiosity is the main reason, and sharing with regular sexual partners is common. Rush use will increase the risk of high-risk sexual behavior and HIV infection; and hence, targeted health education should be strengthened.
