目的:了解MSM中精神活性物质流行情况，分析使用的相关因素。方法:2019年7-12月，在6个省份依托以MSM为主要服务对象的社会组织从社区中招募研究对象，纳入标准为≥18岁男性，发生过男男性行为或主要性取向为男性、知情同意。采用匿名自填网络调查问卷，收集社会人口学特征、性行为情况、精神活性物质使用情况等信息。采用多因素logistic回归分析精神活性物质使用的相关因素。结果:共纳入MSM 2 616人，其中32.2%（841/2 616）用过至少1种精神活性物质，使用最多的是Rush，占使用人数的92.4%（777/841）。使用≥2种精神活性物质的人占使用人数的14.4%（121/841），其中，使用过Rush和零号胶囊的最多（79.7%，98/121）。在控制调查省份影响后，多因素logistic回归结果显示，MSM使用精神活性物质的相关因素有：<35岁（<25岁：n OR=1.28，95%n CI：1.02~1.61；25~34岁：n OR=1.34，95%n CI：1.08~1.67）、主要性角色为插入方（n OR=1.47，95%n CI：1.22~1.77）、最近一次性行为对象为临时性伴（n OR=1.21，95%n CI：1.01~1.45）、最近6个月使用烟草制品（n OR=1.29，95%n CI：1.06~1.56）。n 结论:以Rush为代表的精神活性物质在MSM中广泛流行，以青年人为主，主要性角色为插入方、有临时性伴、使用烟草制品者报告的使用比例较高，需要针对该特殊人群采取精准综合干预措施，减少其精神活性物质使用及相关危害。“,”Objective:To assess the prevalence of psychoactive substances use in men who have sex with men (MSM) and its related risk factors.Methods:From July to December 2019, MSM in 6 provinces were recruited from social MSM organizations in communities. The inclusion criteria were male, age ≥18 years, having had sex with men or male homosexuality, voluntary participation and informed consent. Data collected through an anonymous self-filled online questionnaire including socio-demographic characteristics, sexual behavior and psychoactive substance use. Multivariate logistic regression was performed to examine factors correlated with psychoactive substances use.Results:A total of 2 616 MSM were included in the study. Overall, 32.2% (841/2 616) of MSM had ever used at least one psychoactive substances, of whom 92.4% (777/841) were Rush users and 14.4% (121/841) were multi drug users. Rush and tryptamine were used the most (79.7%,98/121). After adjusting the influence of province, factors associated with psychoactive substances use included age <35 years (<25: n OR=1.28, 95%n CI: 1.02-1.61; 25-34: n OR= 1.34, 95%n CI: 1.08-1.67) , active sexual role preference (n OR=1.47, 95%n CI: 1.22-1.77), having non-regular partners in last sex (n OR=1.21, 95%n CI: 1.01-1.45) and use of tobacco products in the past 6 months (n OR=1.29, 95%n CI: 1.06-1.56).n Conclusions:Psychoactive substances like Rush are popular among MSM, especially in the younger ones. MSM who played active sexual role, had non-regular sex partners and used tobacco also reported higher level of psychoactive substance use. Our findings suggest the urgent need for precise and comprehensive interventions to control the use of psychoactive substances and related hazards in young MSM.
