To understand the characteristics of new-type drug consumption, sexual behaviors and the prevalence of HIV infection among male new-type drug users in Qingdao, Shandong province. A cross sectional survey was conducted from 2015 to 2016. Participants were recruited from MSM community-based organizations (CBO) and general community through snowball method, relying on volunteers and male peer educators who were on new-type drugs themselves. Face-to-face interview was carried to collect information on drug use and sexual behaviors. Blood samples were collected to test HIV, syphilis and HCV antibodies. Urine samples were collected to test the evidence of new-type drugs. Qualitative variables and quantitative variables were analyzed using Chi-square test/Fisher's exact test and Student's -test respectively. Multivariate logistic regression was used to analyze related factors of binary variables. A total of 1 034 newtype drug users were recruited, including 431 (41.7) MSM population and 603 (58.3) who were not MSM. Compared with the the group of people who were not MSM, people in the the MSM group were younger, unmarried and with higher level of education. The proportion of methamphetamine users were 49.7 (214/431) and 100.0 (603/603) among the groups of MSM or not MSM, respectively. People in the MSM group, 66.8 (288/431) used 5-Methoxy-N, N-diisopropyltryptamine (5-MeODIPT, "foxy" ) in the last six months. However, none from the not-MSM group ever used 5-MeO-DIPT. In the last six months, proportions of sharing new-type drugs with more than two people in the MSM or not groups were 87.9 (379/431) and 97.7 (588/602), respectively ((2)=39.84, <0.01). Proportions of unprotected sexual behavior among the MSM or not groups were 47.5 (285/600) and 7.4 (32/430) respectively ((2)=190.10, <0.01). The proportions of 'group sex' after using drugs among the two groups were 78.1 (335/429) and 5.5 (33/600) respectively ((2)=573.73, <0.01). The prevalence rates of HIV, syphilis and HCV antibody positive among the MSM or not groups were 2.1 and 0.2, 3.3 and 6.3, 0.0 and 0.3, respectively. The prevalence of sharing new-type drugs with more than two people was high among male new-type drug users in Qingdao city. Male new-type-drug-users who were MSM, presented both high prevalence of group sex and HIV infection, and with less condom use. Intervention measures towards this sub-population should be strengthened.
为了解山东省青岛市男性新型毒品使用者的新型毒品消费特征、性行为及HIV感染流行情况。于2015年至2016年开展了一项横断面调查。通过滚雪球法，依托志愿者以及自身吸食新型毒品的男性同伴教育者，从男男性行为者社区组织（CBO）和普通社区招募参与者。进行面对面访谈以收集吸毒和性行为信息。采集血样检测HIV、梅毒和HCV抗体。采集尿样检测新型毒品证据。定性变量和定量变量分别采用卡方检验/费舍尔精确检验和t检验进行分析。采用多因素logistic回归分析二元变量的相关因素。共招募了1034名新型毒品使用者，其中431名（41.7%）为男男性行为人群，603名（58.3%）非男男性行为人群。与非男男性行为人群相比，男男性行为人群年龄更小、未婚且文化程度更高。男男性行为人群和非男男性行为人群中甲基苯丙胺使用者的比例分别为49.7%（214/431）和100.0%（603/603）。男男性行为人群中，66.8%（288/431）在过去6个月使用过5-甲氧基-N，N-二异丙基色胺（5-MeODIPT，“迷幻蘑菇”）。然而，非男男性行为人群中无人使用过5-MeO-DIPT。在过去6个月，男男性行为人群和非男男性行为人群中与两人以上共用新型毒品的比例分别为87.9%（379/431）和97.7%（588/602）（χ2=39.84，P<0.01）。男男性行为人群和非男男性行为人群中无保护性行为的比例分别为47.5%（285/600）和7.4%（32/430）（χ2=190.10，P<0.01）。两组中吸毒后“群交”的比例分别为78.1%（335/429）和5.5%（33/600）（χ2=573.73，P<0.01）。男男性行为人群和非男男性行为人群中HIV、梅毒和HCV抗体阳性的患病率分别为2.1%和0.2%、3.3%和6.3%、0.0%和0.3%。青岛市男性新型毒品使用者中与两人以上共用新型毒品的情况较为普遍。男男性行为的男性新型毒品使用者群交和HIV感染患病率均较高，且使用避孕套较少。应加强对这一亚人群的干预措施。
