四川省男男性行为人群rush poppers使用及其影响因素分析

目的 了解四川省男男性行为人群(men who have sex with men, MSM)rush poppers使用现状及影响因素。 方法 采用方便抽样的方法在四川省德阳、宜宾和西昌3个城市招募调查对象,对MSM进行自填式匿名问卷调查。采用非条件logistic回归模型对MSM 使用rush poppers进行影响因素分析。 结果 本研究共招募合格调查对象1 122例。调查对象以25岁以上、未婚、四川户籍、高中及以下文化程度、服务/个体或其他职业及收入在3 000元以上者为主。27.7%的调查对象报告曾使用过新型毒品,rush poppers为MSM最常使用的新型毒品(24.1%)。logistic回归分析显示,性角色为被插入方(OR=2.488, 95%CI: 1.587～3.901)或双重性角色(OR=2.233, 95%CI: 1.494～3.340)、初次性行为年龄＜18岁(OR=1.424, 95%CI: 1.025～1.978)、近1年饮酒(OR=2.347, 95%CI: 1.473～3.740)及群交性行为(OR=1.681, 95%CI: 1.113～2.539)是MSM使用rush poppers的影响因素。 结论 四川省MSM rush poppers使用比例较高,且rush poppers使用与群交性行为等HIV高危因素叠加,将进一步增加MSM感染和传播HIV的风险。因此,应根据使用人群的社会人口学及行为特征制定针对性的干预策略,从而降低该人群感染和传播艾滋病的风险。

Prevalence of rush poppers use and its influencing factors among men who have sex with men in Sichuan Province

Objective To explore the prevalence and influencing factors of rush poppers use among men who have sex with men(MSM) in Sichuan Province. Methods A convenience sampling method was used to recruit surveyed subjects in Deyang City, Yibin City and Xichang City, Sichuan Province, and a self-administered anonymous questionnaire survey was conducted. Non-conditional logistic regression model was used to analyze the factors affecting rush poppers use among MSM. Results A total of 1,122 eligible MSM were enrolled into this study. The majority of the participants were more than 25 years old, single and local residents, had a senior high school education level or below, were solo business owners, service providers or others and had a monthly income of more than 3,000 Yuan. 27.7% of the participants reported having used at least one type of recreational drugs in the lifetime and rush poppers were the most commonly used drug (24.1%) among MSM. Logistic regression analysis indicated that preferring receptive anal intercourse (OR=2.488, 95%CI:1.587-3.901) or versatile anal intercourse (OR=2.233, 95%CI:1.494-3.340), age at sexual debut < 18 years (OR=1.424, 95%CI:1.025-1.978), alcohol use in the last year (OR=2.347, 95%CI:1.473-3.740) and engaging in group sex (OR=1.681, 95%CI:1.113-2.539) were the factors influencing rush poppers use among MSM. Conclusion Rush poppers use was common among MSM in Sichuan Province. The overlap of rush poppers use and other risky behavior like group sex can place MSM at increased risk for infection with and transmission of HIV. Therefore, targeted intervention measures should be tailored based on the sociodemographic and behavioral characteristics of rush poppersusers so as to decline the risk of HIV infection and transmission among MSM.
