Drug use is globally more prevalent in HIV-positive men who have sex with men (HIVMSM) than their heterosexual counterparts. Yet, few studies have investigated the factors associated with drug use among this population beyond Western societies. A cross-sectional survey was conducted to examine factors associated with drug use among 415 HIVMSM in Chengdu, China. The results show that 10.8% of the participants had used drugs in the past 30 days. Among participants who had anal intercourse in the past 30 days, 11.5% had used drugs during anal intercourse. After adjusting for background variables, logistic regression models show that life satisfaction was associated with past 30-day drug use [Adjusted Odds Ratio (ORa) = 0.90, p < 0.001], and with drug use during anal intercourse in the past 30 days (ORa = 0.89, p < 0.01). Participants with more nonregular partners were more likely to use drugs with or without sex in the past 30 days, whereas those with one regular partner were less likely to use drugs during anal intercourse compared to their counterparts with no regular partners. The findings of this study are informative for designing effective substance-use intervention programs targeting HIVMSM.
在中国成都，研究人员对 415 名 HIV 男性同性性行为者（MSM）进行了横断面调查，以检验与该人群药物使用相关的因素。结果显示，过去 30 天内，10.8%的参与者有过药物使用史。在过去 30 天内有过肛交行为的参与者中，11.5%的人在肛交时使用了药物。调整背景变量后，逻辑回归模型显示，生活满意度与过去 30 天的药物使用有关（调整后的优势比（ORa）=0.90，p<0.001），与过去 30 天的肛交药物使用有关（ORa=0.89，p<0.01）。与没有固定性伴侣的参与者相比，非固定性伴侣较多的参与者更有可能在过去 30 天内发生无性行为或有性行为的药物使用，而有一个固定性伴侣的参与者在肛交时使用药物的可能性较小。本研究结果为针对 HIVMSM 设计有效的药物使用干预计划提供了信息。
