【摘要】 目的分析2010-2014年红河州MSM哨点人群艾滋病相关行为变化趋势及安全套使用影响因素,为制定艾滋病防控策略和行为干预提供依据。方法以重复横断面调查方法,对2010-2014年红河州MSM哨点进行问卷调查和采血,以获取此类人群一般人口学特征、行为学特征、血清学信息、艾滋病防治有关信息。结果 2010-2014年红河州MSM哨点人群最近六个月与同性肛交性行为比例五年间变化不大,平均为89.0%,但最近一次与同性发生性行为时安全套使用率(χ~2=48.686,P=0.000)、最近六个月内坚持使用安全套比例(χ~2=108.923,P=0.000)、最近一年做过HIV检测比例均呈现逐年升高的趋势(χ~2=88.252,P=0.000),而最近六个月与同性发生商业性行为比例有逐年下降的趋势(χ~2=42.271,P=0.000)。不同年份影响MSM人群坚持使用安全套的因素虽然有所不同,经多因素logistic回归分析发现MSM人群未坚持使用安全套的主要危险因素有不知晓艾滋病知识(OR=13.961,95%CI:3.71～52.61,P=0.000)、未做过HIV检测(OR=4.513,95%CI:2.73～7.46,P=0.000)、未婚或离异人群(OR=2.642,95%CI:1.33～5.24,P=0.005)、初中及以下文化程度(OR=4.138,95%CI:1.36～12.55,P=0.012)、样本来源以"滚雪球"招募方式监测的MSM人群(OR=0.217,95%CI:0.09～0.53,P=0.001)。结论红河州要加大针对初中及以下文化程度,未婚或离异人群、样本来源以"滚雪球"招募方式监测的MSM人群干预力度,促进其安全套使用,从而降低HIV在男男性行为人群中的传播。更多还原

【Abstract】 Objective To analyze the changing trend of HIV-related behavior and the factors influencing condom use among men who have sex with men(MSM) in Honghe Prefecture from 2010 to 2014 so as to provide references for formulatng HIV prevention and control strategies and conducting behavior intervention. Methods Repeated cross-sectional survey method was used to obtain demographic characteristics,behavior characteristics,serological information and HIV-related prevention and treatment information of MSM in the sentinel points in Honghe Prefecture from 2010 to 2014. Results The proportion of MSM who had anal sex with men in the past six months remained stable in Honghe Prefecture during 2010-2014,with the average rate of 89%.The rate of condom use in the last homosexual behavior(χ~2= 48.686,P = 0.000),the proportion of persistent condom use in the past six months(χ~2= 108.923,P = 0.000) and the proportion of having had HIV testing in the past year(χ~2= 88.252,P = 0.000)showed a gradually increasing tendency,while the proportion of commercial homosexual behavior displayed a decreasing tendency year by year(χ~2= 42.271,P = 0.000). Although the factors influencing persistent condom use in different years were various,multivariate logistic regression analysis indicated that the main risk factors for incontinuous condom use in MSM were low awareness of HIV/AIDS-related knowledge(OR = 13.961,95%CI: 3.71-52.61,P = 0.000),receiving no HIV/AIDS detection(OR = 4.513,95%CI: 2.73-7.46,P = 0.000),the unmarried or divorced(OR = 2.642,95%CI: 1.33-5.24,P = 0.005),the education level of junior middle school or below(OR = 4.138,95% CI: 1.36-12. 55,P = 0. 012) and the monitored MSM recruited by the snowball sampling method(OR = 0.217,95%CI: 0. 09-0. 53,P = 0. 001). Conclusions It is necessary to enhance interventions and promote condom use among MSM with the education level of junior middle school or below,the unmarried or divorced MSM and the monitored MSM recruited by the snowball sampling method and so as to decline the transmission of HIV among MSM group.更多还原
