摘　　要：目的 了解男男性行为者(MSM)固定性伴相关特征,分析固定性伴发生无保护肛交(UAI)的影响因素。方法 采用“滚雪球”抽样法,开展四川省绵阳市MSM固定性伴相关特征等问卷调查和血清学检测,用χ;检验、Logistics回归模型分析固定性伴发生UAI影响因素的单因素及多因素分析。结果 有效问卷1117份,91.3%过去/现在、61.5%近6个月拥有固定性伴,固定性伴维持时间中位数12个月。近6个月拥有固定性伴期间31.9%有其他性伴,固定性伴间UAI发生率28.9%,固定性伴不使用安全套原因为没有必要60.9%,影响感情14.9%,影响快感7.5%。过去/现在、近6个月是否拥有固定性伴者HIV、梅毒阳性率差异无统计学意义(P均>0.05),近6个月固定性伴未发生UAI者HIV、梅毒阳性率低于发生UAI者(P均<0.05)。多因素分析结果,干部职员(OR=2.884)、工人/其他(OR=2.338)、固定性伴维持时间>12个月(OR=2.061)、近6个月偶遇性伴(OR=2.242)、近6个月多性伴(OR=1.974)者固定性伴发生UAI的可能较大,文化程度提高(OR=0.623)、社会活动网络较大(OR=0.384)、近1年接受同伴教育(OR=0.601)者固定性伴发生UAI的可能较小(P均<0.05)。结论 MSM固定性伴维持时间、专一性及性行为保护不足,潜在健康风险明显。固定性伴发生UAI受人口学特征、维持时间和性行为影响,应针对性强化健康教育。Objective To understand the characteristics of fixed sexual partners of men who have sex with men(MSM),and to analyze the influencing factors of unprotected anal intercourse(UAI)in fixed sexual partners. Methods Snowball sampling method was used, and questionnaire surveys and serological tests were carried out to collect the characteristics of MSM fixed sex partners in Mianyang City, Sichuan Province.Single and multivariate analysis of the influencing factors of UAI in fixed partners were analyzed by χ~2 test and logistic regression model. Results There were 1117 valid questionnaires.91.3% of them had a fixed partner in the past or present, 61.5% had a fixed partner in the past 6 months, and the median duration of having a fixed partner was 12 months.During the period of having a fixed partner in the past 6 months, 31.9% had other sexual partners, and the incidence of UAI between fixed partners was 28.9%.The reasons why fixed partners did not use condoms were unnecessary(60.9%),affecting relationship between them(14.9%),and affecting pleasure(7.5%). There was no significant difference in the positive rates of human immunodeficiency virus(HIV)and syphilis in the people of past or present and recent 6 months(P>0.05). The positive rates of HIV and syphilis in those with fixed sexual partners without UAI in the past 6 months were lower than the fixed sexual partners with UAI(P<0.05). The results of multivariate analysis showed that the maintenance time of cadres and staff(OR=2.884),workers or others(OR=2.338),fixed sexual partners> 12 months(OR=2.061),occasional encounters with sexual partners in the past 6 months(OR=2.242),and having fixed sexual partners in the past 6 months(OR=1.974)were more likely to have UAI(P<0.05). And improved educational level(OR=0.623),larger social activity network(OR=0.384),and having received peer education in the past years(OR=0.601)were less likely to have UAI in their fixed sexual partners(P<0.05). Conclusion MSM has inadequate maintenance time for fixed sexual partners, specificity
