HIV感染者安全套使用情况及影响因素分析

目的 了解人类免疫缺陷病毒(HIV)感染者的安全套使用情况及影响因素.方法 2006年1月-2008年6月,采用方便抽样方法,对946例被告知HIV阳性的感染者采用匿名问卷调查法调查其一般情况、艾滋病知识知晓情况、被告知HIV阳性检测结果后的性行为及安全套使用情况等.结果 调查对象经吸毒感染占22.1%,经性传播感染占69.6%.艾滋病知识知晓率为93.4%;655人过去6个月发生过性行为,平均安全套使用率为55.3%;97人最近1次与固定性伴发生性行为时使用了安全套.单因素和多因素Logistic回归分析结果均显示,不同民族(OR=5.61,95%CI=1.66~18.94)、免费安全套的可及性(OR=0.33,95%CI=0.13~0.85)、家庭人均月收入(OR=0.26,95%CI=0.10~0.69)等因素与最近1次性行为时是否使用安全套有关.结论 知晓自己感染状态的HIV阳性人群艾滋病知晓率普遍较高,但仍有相当数量的感染者发生性行为时不能坚持使用安全套甚至不使用安全套,危险性行为的发生率仍然较高.
