To understand the relationship between new-type drug use and high risk behavior in men who have sex with men (MSM) in Shandong province. Cross-sectional surveys was conducted to collect the information about demographics, sexual and drug use behaviors of MSM and HIV-related services in MSM in three sentinel surveillance sites in Shandong from April to July in 2019. Blood samples were taken from the MSM for serological tests of HIV antibody and syphilis antibody. A total of 1 203 MSM were included in this study. The average age of the MSM was 30.2±8.9 years. Among these MSM, 67.7 (815) were unmarried; 66.9 (805) had education level of college or above; 62.2 (721/1 160) had unprotected sex behaviors and 16.3 (189/1 160) had group sex behavior in the past six months and 54.2 (652/1 203) ever used new-type drugs. HIV infection and syphilis prevalence rates were 3.1 (37/1 203) and 4.7 (56/1 203), respectively. Multivariable logistic analysis indicated that MSM who had unprotected anal sex in the past six months were more likely to be from Qingdao (a=1.59, 95:1.13-2.23), with education level of high school or below (a=1.61, 95: 1.20-2.16), with male sex partners from bars/dance halls or other venues (a=1.69, 95: 1.06-2.69), with HIV knowledge awareness score <6 (a=1.55, 95: 1.01-2.37), with ≥2 sex partner in the past week (a=1.48, 95: 1.12-1.95), to have group sex behaviors in the past six months (a=2.43, 95:1.61-3.67) and to use new-type drugs (a=1.46, 95: 1.11-1.91). MSM who had group sex were more likely to have following features: being from Qingdao (a=2.21, 95: 1.45-3.38), non-Shandong residents (a=2.13, 95: 1.28-3.55), HIV knowledge awareness score ≥6 (a=3.11, 95: 1.55-6.25), ever having unprotected anal sex behaviors (a=2.60, 95: 1.71-3.96) and ever having male commercial sex (a=3.38, 95: 1.92-5.95) in the past six months, ever using new-type drugs (a=2.71, 95: 1.82-4.04), and never having HIV testing in the past year (a=2.66, 95: 1.59-4.43). New-type drug use is common in MSM in Shandong. The use of new-type drugs promotes unprotected sex and group sex in MSM. Surveillance and intervention measures targeting this population should be strengthened.
了解山东省男男性行为者（MSM）新型毒品使用情况与高危行为之间的关系。于2019年4月至7月在山东省3个哨点监测地区开展横断面调查，收集MSM的人口学信息、性与毒品使用行为以及MSM相关艾滋病服务情况。采集MSM血样进行HIV抗体和梅毒抗体血清学检测。本研究共纳入1203名MSM。MSM的平均年龄为30.2±8.9岁。在这些MSM中，67.7%（815名）未婚；66.9%（805名）学历为大专及以上；62.2%（721/1160）在过去6个月有不安全性行为，16.3%（189/1160）在过去6个月有群交行为，54.2%（652/1203）曾使用新型毒品。HIV感染率和梅毒患病率分别为3.1%（37/1203）和4.7%（56/1203）。多因素logistic分析显示，过去六个月有不安全性行为的MSM更可能来自青岛（a=1.59，95%CI：1.13-2.23）、高中及以下学历（a=1.61，95%CI：1.20-2.16）、男性性伴来自酒吧/舞厅或其他场所（a=1.69，95%CI：1.06-2.69）、HIV知识知晓得分<6分（a=1.55，95%CI：1.01-2.37）、过去一周有≥2个性伴（a=1.48，95%CI：1.12- .195）、过去六个月有群交行为（a=2.43，95%CI：1.61-3.67）以及使用新型毒品（a=1.46，95%CI：1.11-1.91）。有群交行为的MSM更可能具有以下特征：来自青岛（a=2.21，95%CI：1.45-3.38）、非山东籍居民（a=2.13，95%CI：1.28-3.55）、HIV知识知晓得分≥6分（a=3.11，95%CI：1.55-6.25）、过去六个月曾有不安全性行为（a=2.60，95%CI：1.71-3.96）、过去六个月曾有男性商业性行为（a=3.38，95%CI：1.92-5.95）、曾使用新型毒品（a=2.71，95%CI：1.82-4.04）以及过去一年从未进行过HIV检测（a=2.66，95%CI：1.59-4.43）。新型毒品在山东省MSM中使用普遍。新型毒品的使用促使MSM发生不安全性行为和群交行为。应加强针对该人群的监测和干预措施。
