目的了解男男性行为人群(MSM)多性伴和高危性行为现状,探讨该人群高危性行为与生活质量之间的关系,为今后在该人群中开展有效的行为干预提供科学依据。方法采用横断面研究方法,对北京、成都、沈阳、广州、青岛、乌鲁木齐和合肥市7城市中,在“同性恋酒吧”活动的MSM进行匿名自填式问卷调查。结果 339名调查对象的平均年龄为(27.81±7.15)岁。有127人(37.46%)曾经有过异性性伴,其均数为(3.46±4.22)个;所有的调查对象均拥有过同性性伴,拥有同性性伴的均数为(12.79±12.89)个。MSM在与异性发生性行为时,每次都使用安全套的只有26.7%;在与同性发生性行为时,每次都使用安全套的为50.5%;在最近3次同性肛交时,每次都使用安全套的为53.6%,而与异性发生性行为时3次都使用安全套的只有23.6%。多因素线性回归分析(Back-ward法)表明,变量“终生同性性伴数”、“终生同性商业性性伴数”、“最近3次同性偶然性伴肛交高危性行为”和“最近2个月双性高危性行为”进入了生活质量总分回归方程中。结论在MSM人群中多性伴和高危性行为普遍存在并且与生活质量相关。在今后的干预中,要关注MSM人群的心理健康状况以降低多性伴和高危性行为的情况发生。
Objective To understand the prevalence of multiple sexual partners and high-risk behaviors among men who have sex with men (MSM) and to explore the relationship between high-risk sexual behaviors and quality of life in this population and to provide a scientific basis for effective behavioral intervention in this population. Methods A cross-sectional study was conducted to investigate the anonymous self-administered questionnaire of MSM in “Gay Bars” in Beijing, Chengdu, Shenyang, Guangzhou, Qingdao, Urumqi and Hefei. Results The average age of 339 subjects was (27.81 ± 7.15) years. A total of 127 (37.46%) had heterosexual partners, with a mean of 3.46 ± 4.22. All subjects had homosexual partners and homosexual partners with a mean of (12.79 ± 12.89) . MSM used only 26.7% of condoms each time it was sexually associated with the opposite sex, 50.5% used condoms each time it had sex with the same sex, and condoms each time it used the same sex anal sex Compared with 53.6% for the same sex and 23.6% for condom use three times during heterosexual sex. Multivariate linear regression analysis (Back-ward method) showed that the variables “lifetime same-sex sexual partners”, “lifelong same-sex sexual partners”, “3 most recent same-sex sexual partners with high risk sex” And “the last two months of high risk sexual behavior” into the quality of life regression equation. Conclusions Multi-sexual partners and high-risk behaviors are prevalent in MSM population and are associated with quality of life. In future interventions, pay attention to the mental health status of MSM population to reduce the occurrence of multiple sexual partners and high-risk sexual behavior.
