浙江省兰溪市艾滋病病毒感染者和艾滋病病例晚发现影响因素分析

Influencing Factors Late Detection of HIV/AIDS Cases in Lanxi of Zhejiang Province

目的:了解2003—2020年兰溪市晚发现艾滋病病毒感染者和艾滋病(简称HIV/AIDS)病例的特征及影响因素,从而制定科学的防控策略。方法:从艾滋病防治信息系统中,收集兰溪市2003—2020年新报告的HIV/AIDS病例基本信息、样本来源以及感染途径等资料,计算兰溪市HIV/AIDS病例晚发现率,采用logisitic回归模型分析晚发现的影响因素。结果:2003—2020年兰溪市新报告HIV/AIDS病例249例,晚发现127例,晚发现率为51.00%,不同年份晚发现率差异无统计学意义(P=0.548)。多因素logisitic回归分析显示,≥50岁年龄组晚发现风险较高,大约是≤24岁年龄组的3.786(1.423-10.076)倍;医务人员主动提供HIV检测咨询和自愿检测咨询(PITC/VCT)组晚发现风险较低,大约是其他检测组的0.451(0.254-0.802)倍。结论:兰溪市新报告HIV/AIDS病例晚发现率较高,年龄、样本来源是影响HIV/AIDS病例晚发现的主要原因,应继续加强≥50岁老年人群的HIV检测力度,同时在艾滋病防治工作中积极推进PITC和VCT。

OBJECTIVE To understand the characteristics and influencing factors of late HIV/AIDS cases in Lanxi from 2003 to2020,so as to formulate scientific prevention and control strategies.METHODS Basic information,source of samples and infection route of newly reported HIV/AIDS cases in Lanxi from 2003 to 2020 were collected from THE AIDS prevention and treatment information system,and the rate of late detection of HIV/AIDS cases in Lanxi was calculated.Logisitic regression model was used to analyze the influencing factors of late detection.RESULTS From 2003 to 2020,249 new CASES of HIV/AIDS were reported in Lanxi,and 127 cases were discovered late,with a late detection rate of 51.00%.There was no significant difference in late detection rate among different years(P=0.548).Multivariate Logisitic regression analysis showed that the risk of late discovery was higher in≥50years old group than in≤24 years old group,which was 3.786(1.423-10.076)times.The risk of late development was 0.451(0.254-0.802)times higher in the PITC/VCT group than in the other testing groups.CONCLUSION The late detection rate of newly reported HIV/AIDS cases is relatively high in Lanxi.Age and sample source are the main reasons affecting the late detection of HIV/AIDS cases.It is necessary to continue to strengthen HIV detection in elderly population≥50 years old,and actively promote PITC and VCT in AIDS prevention and treatment.
