低档暗娼人口社会行为学特征与HIV感染状态

目的了解低档暗娼艾滋病病毒（HIV）感染现状,分析相关危险因素。方法按照广西低档暗娼人群专项调查工作方案要求进行问卷、采血、检测。资料经Epidata 3.1进行双录入,用SPSS 19.0进行统计分析。结果共调查低档暗娼7 936人,HIV感染率为1.88%（149例）。其中〉40岁年龄段者HIV感染率为4.63%,文盲者HIV感染率4.54%,离异/丧偶者HIV感染率4.91%,有吸毒行为者HIV感染率达6.42%,流动性暗娼（没有固定场所）的HIV感染率为4.02%。从未使用安全套者,HIV感染率明显高于每次使用者（P〈0.05）;艾滋病知识知晓率低分组,HIV感染也明显高于艾滋病知识知晓率高分组（P〈0.01）。经多因素Logistic回归分析,影响低档暗娼HIV感染率的主要危险因素有：无固定场所、有吸毒行为、〉40岁、越南籍。结论广西低档暗娼HIV感染率较高,不同人口社会学和行为特征的暗娼HIV感染率不同,需对影响感染及传播的因素实施有效的干预措施,加大健康教育、监测与干预力度,做到早干预、早发现、早治疗,有效减少艾滋病在这类人群中和向其他人群的传播。
