目的了解天津市2004-2015年报告的艾滋病病毒感染者/艾滋病患者(HIV/AIDS患者)晚发现的比例及影响因素。方法统计2004年1月~2015年6月全国艾滋病防治信息系统中天津市报告的HIV/AIDS患者晚发现比例,运用多因素logistic回归对其影响因素进行相关性分析。结果天津市报告HIV/AIDS患者3 447例,晚发现比例35.10%,已婚、异性传播、术前检测、咨询检测、其他就诊者检测发现的患者晚发现风险高。结论天津市艾滋病晚发现并未得到有效遏制,应该加强高危人群HIV主动检测工作,做到早发现,早治疗。 Objective To understand the late detection rate and influencing factors of HIV / AIDS patients (HIV / AIDS patients) reported in Tianjin from 2004 to 2015. Methods The proportion of late-onset HIV / AIDS patients reported in Tianjin AIDS Prevention and Control Information System from January 2004 to June 2015 was statistically analyzed. Multivariate logistic regression analysis was used to analyze the influencing factors. Results Tianjin reported 3 447 cases of HIV / AIDS patients, 35.10% of them were late found, married, heterosexual transmission, preoperative examination, counseling and testing, and those found by other clinicians were later found to be at higher risk. Conclusion The late detection of HIV / AIDS in Tianjin has not been effectively checked, HIV positive testing should be strengthened in high-risk groups to achieve early detection and early treatment.
