MSM通常采用血清分选来降低艾滋病毒风险。我们假设MSM认为血清分选是有效的，血清分选预测的弹性和呈负相关的流行特征。调查包括504名使用物质的男男性行为者。Logistic回归模型分别按血清状态检查血清分类的流行病学和恢复力预测因子。对于HIV阳性男性，积极应对行为（P = 0.015）和应对自我效能（P = 0.014）预测血清分类的几率较高，而认知逃避行为（P = 0.003）的几率较低。对于HIV阴性男性，社会参与（P = .03）和应对自我效能（P = .01）预测血清分类的几率较高，严重精神困扰（P = .001），受害史（P = .007）和认知逃避行为（P = .006）的几率较低。HIV阴性血清分类者报告的感染风险感知低于非血清分类者（P <0.000）。虽然高风险的HIV阴性男性可能认为血清分选是有效的，但他们的UAI和伴侣改变的高比率使其成为一种无效的降低风险的方法。迫切需要相关的公共卫生信息。
Serosorting is commonly employed by MSM to reduce HIV risk. We hypothesize that MSM perceive serosorting to be effective, and that serosorting is predicted by resilience and inversely related to syndemic characteristics. Surveys included 504 substance-using MSM. Logistic regression models examined syndemic and resilience predictors of serosorting, separately by serostatus. For HIV-positive men, positive coping behaviors (P = .015) and coping self-efficacy (P = .014) predicted higher odds, and cognitive escape behaviors (P = .003) lower odds, of serosorting. For HIV-negative men, social engagement (P = .03) and coping self-efficacy (P = .01) predicted higher odds, and severe mental distress (P = .001), victimization history (P = .007) and cognitive escape behaviors (P = .006) lower odds, of serosorting. HIV-negative serosorters reported lower perceptions of risk for infection than non-serosorters (P < .000). Although high risk HIV-negative men may perceive serosorting to be effective, their high rates of UAI and partner change render this an ineffective risk reduction approach. Relevant public health messages are urgently needed.
