研究背景男男性接触者（MSM）中HIV感染率和发病率较高.无保护肛交（UAI）是一种重要但未被重视的危险行为。本研究旨在探讨中国香港地区男男性行为者与固定性伴的UAI发生率及其影响因素。共招募了285名参与者，其中211人（75.1%）在过去六个月内与RP发生过肛交，并在本报告中对他们的数据进行了分析。结果参与者在过去6个月的高危行为包括有UAI与RP（45.8%），有非正规男性性伴侣（NRP：27.3%）和UAI与这样的合作伙伴（18.9%）的高患病率。调整社会人口统计学变量后，与UAI伴RP相关的因素包括：1）肛交前使用药物（65.7%对43.8%; AOR =2.36; 95%CI =1.07-5.18），2）担心使用安全套象征着不信任（67.9%vs44.3%，AOR = 2.91，95%CI =1.19-7.10）; 3）RP对安全套使用的接受程度较低（91.7%对38.3%; AOR = 22.70; 95%CI =6.20-83.10），和4）更高水平的冲动（61.1%对35.0%; AOR =4.02; 95%CI = 1.62-9.97）。其中两个变量，物质使用（ORm = 2.28，95%CI = 1.01-5.16）和RP的安全套使用的接受程度（ORm = 17.22，95%CI = 5.06-58.62）的感知较低的水平，被选中的前向逐步logistic回归model.ConclusionsMSM与RP在香港是受到HIV传播的高风险。UAI的危险因素是多方面的，干预措施需要考虑结构、人际和个体层面的因素。
BackgroundThe HIV prevalence and incidence among men who have sex with men (MSM) are high. Unprotected anal intercourse (UAI) with male regular partners (RP) is an important but under-emphasized risk behavior. The current study aimed to describe the prevalence of UAI with regular partner and the associated multi-dimensional factors with UAI among MSM in Hong Kong, China.MethodsRespondent Driven Sampling method was used to recruit participants. A total of 285 participants were recruited, of whom 211 (75.1%) had had anal sex with RP in the last six months and their data were analyzed in this report. Weighed data were presented and logistic regression methods were fit.ResultsParticipants’ high risk behaviors in the last six months included high prevalence of having had UAI with RP (45.8%), having had non-regular male sex partners (NRP: 27.3%) and UAI with such partners (18.9%). Adjusted for socio-demographic variables, factors associated with UAI with RP included: 1) substances use prior to having anal sex (65.7% versus 43.8%; AOR =2.36; 95% CI =1.07-5.18), 2) worry that condom use symbolizes mistrust (67.9% versus 44.3%; AOR = 2.91; 95% CI =1.19-7.10), 3) a lower perceived degree of the RP’s acceptance of condom use (91.7% versus 38.3%; AOR = 22.70; 95% CI =6.20-83.10), and 4) a higher level of impulsivity (61.1% versus 35.0%; AOR =4.02; 95% CI = 1.62-9.97). Two of these four variables, substances use (ORm = 2.28, 95% CI = 1.01-5.16) and perceived lower level of RP’s acceptance of condom use (ORm = 17.22; 95% CI = 5.06-58.62) were selected by the forward stepwise logistic regression model.ConclusionsMSM with RP in Hong Kong is subjected to high risk of HIV transmission. Risk factors of UAI are multi-dimensional and interventions need to take into account factors of structural, interpersonal and individual levels.
