摘要
目的了解乌鲁木齐市男男性行为人群HIV/STD新发感染率及其影响因素,指导采取和调整相应的控制男男性行为人群HIV传播流行的措施和策略。方法调查对象为在乌鲁木齐市工作、生活或学习的男男性行为者,纳入标准为18岁及以上男性,近6个月有同性性行为,HIV检测为阴性,将在乌鲁木齐居住1a。在本底调查、6个月和12个月随访时每次进行检测前咨询、采集血样进行HIV、梅毒、生殖器疱疹病毒-2(HSV-2)抗体检测。结果 (1)HIV抗体阴性队列本底人数为340人,总观察时间为282人年,共有8人HIV血清抗体阳转,其HIV新发感染率为2.84/100人年;梅毒抗体阴性队列本底人数为311人,总观察时间为229人年,共有7人梅毒血清抗体阳转,其梅毒新发感染率为3.06/100人年;HSV-2抗体阴性队列本底人数为300人,总观察时间为293人年,共有14人HSV-2抗体阳转,其HSV-2新发感染率为4.78/100人年。多因素Cox回归模型分析结果显示,既往吸毒比不吸毒的更容易感染HIV和梅毒,近6个月有同性商业性行为的比没有同性商业性行为的更容易感染梅毒。(2)12个月随访中,近6个月男性性伴数、女性性伴数、近6个月与男性性伴无保护性肛交等均呈下降趋势(P均<0.01)。结论乌鲁木齐市男男性行为人群中,HIV、梅毒、HSV-2的新发感染情况已非常严重,应及时采取针对措施控制该人群中HIV/STD的流行传播。
