结核病人拒绝HIV检测的原因及人口学特征分析

目的分析拒绝HIV抗体检测的结核病人特征，揭示拒绝检测的原因，判断感染HIV的风险大小。方法采用分层整群抽样方法，在31省（自治区、直辖市）333个县对结核病防治机构新登记结核病人开展HIV感染状况调查，在确诊结核病后用知情不拒绝的方式提供HIV检测，用开放式问题收集病人拒绝HIV检测的原因。结果结核病人拒绝HIV抗体检测率为3．3％（1525／45523）。1232例说明了拒绝原因的病人中，5．7％的病人因为“近期做过HIV检测”，14．3％的病人“认为没有必要，无不良行为”，8．4％的病人“健康状况不宜采血”，8．7％的病人“未能到结防机构采血”，4．8％的病人“年纪太小或太大”，54．9％的病人或家属“不同意”或病人“拒绝采血”。拒绝检测者与本次调查发现的HIV阳性者在性别、年龄、职业、民族、文化程度、婚姻状况、居住地、户籍等特征上差异有统计学意义（P〈0．05）。结论拒绝HIV检测的结核病人与HIV阳性病人在各项特征上有较大差别，近半数的病人有合理的拒绝原因、感染HIV风险较低，其余病人拒绝检测的原因和感染风险需要进一步研究。
