摘要目的 了解乌鲁木齐市男男同性性行为人群(MSM)rush poppers使用情况,分析高危性行为在rush poppers使用与人乳头瘤病毒感染之间的中介效应.方法 2018年1—6月在乌鲁木齐市,通过网络、现场宣传等方式招募MSM 651名,使用在线问卷收集数据,并采集肛周脱落细胞进行HPV分型检测.根据Baron和Kenny的判定标准,采用多因素logistic回归分析高危性行为(多性伴、肛交安全套使用)在rush poppers使用与HPV感染之间的中介效应.结果 651名研究对象年龄为(32.0±8.0)岁,近6个月用过rush poppers 174名(26.7%),近6个月性伴数≥2的MSM 350名(46.9%),肛交未使用安全套者188名(28.9%),rush poppers使用者HPV感染率为60.3%(150/174).调整年龄、婚姻状况后,rush使用与HPV的感染有关联[OR(95%CI)值为2.34(1.63~3.36),P<0.05],rush使用与近6个月性伴数有关联[OR(95%CI)值为2.72(1.89~3.93),P<0.05];调整年龄、婚姻状况、近6个月性伴数、肛交安全套的使用后,rush poppers使用与HPV的感染仍有关联[OR(95%CI)值为2.21(1.53~3.19),P<0.05];调整年龄、婚姻状况、rush poppers使用、肛交安全套使用后,近6个月性伴数与HPV的感染仍有关联[OR(95%CI)值为1.46(1.05~2.04),P<0.05].结论 近6个月性伴数在乌鲁木齐MSM rush poppers使用和HPV感染之间存在中介效应,rush poppers使用应成为HPV防控工作关注的重点.

abstractsObjective To study the prevalence of rush poppers use among men who have sex with men (MSM) in Urumqi and to analyze the mediating effect of high-risk sexual behavior between the use of rush poppers and human papillomavirus (HPV) infection. Methods From January to June 2018, 651 MSM were recruited through network and publicity. Data was collected by using online questionnaire and anal swab were collected from them for HPV genotyping. According to Baron and Kenny's criterion, multivariate logistic regression models was used to analyze the mediation effect of high-risks sexual behaviors (multiple sexual partners, anal intercourse condom use) between rush poppers use and HPV infection. Results A total of 651 subjects were (32.0 ± 8.0) years old, and 174 subjects (26.7%)had ever used rush poppers in the past 6 months, while 350 subjects (46.9%) had more than 2 sexual partners and 188 subjects (28.9%) did not use anal condom. After adjusting age and marital status, rush poppers use was associated with HPV infection ( OR (95%CI ) was 2.34 (1.63-3.36), P<0.05), and sexual partners in the past 6 months (OR (95%CI) was 2.72 (1.89-3.93), P<0.05).After adjustment for age, marital status, sexual partners in the past 6 months, and anal condom use, rush poppers use was still associated with HPV infection (OR (95%CI) was 2.21 (1.53-3.19), P<0.05).After adjustment and adjustment of age, marital status, rush poppers use and anal sex condom use, the number of sexual partners at nearly 6 months was still associated with HPV infection ( OR (95%CI ) was 1.46 (1.05-2.04), P<0.05). Conclusion Sexual partners in the past 6 months have a mediation effect between rush poppers use and HPV infection in Urumqi. For the prevention of sexually transmitted diseases, we should focus on rush poppers use.
