目的了解上海市闵行区报告的HIV感染者中男男性行为者(MSM)晚发现率及其影响因素。方法下载“艾滋病综合防治信息系统”中2005年1月1日至2015年12月31日的历史卡片,选择报告地编码为上海市闵行区,传播途径为男男同性传播的病例366例,剔除确诊HIV感染后3个月内无CD4~+T淋巴细胞检测结果的47例,共纳入研究对象319例。结果 2005—2015年闵行区报告的HIV感染MSM病例中晚发现病例103例,晚发现率为32.3%。多因素回归分析显示年龄≥50岁、样本来源为其他(包括外来流动人口检测,其他就诊者检测、术前检测、专题调查等)的晚发现率高于其他组别,OR值(95%CI)分别为12.31(1.12~135.67)和1.94(1.08~3.50)。结论闵行区HIV感染MSM的晚发现率较高,年龄和样本来源是其重要的影响因素,应加强中老年MSM的HIV检测力度。
Objective To investigate the late detection rate of MSM and its influential factors among HIV-infected persons reported in Minhang District, Shanghai. Methods Download the historical card from January 1, 2005 to December 31, 2015 in “Integrated HIV / AIDS Prevention and Control Information System” and select the report code to be 366 cases of MSM transmission in Minhang District of Shanghai 47 patients with no CD4 ~ + T lymphocyte test within 3 months after diagnosis of HIV infection were excluded. A total of 319 subjects were included in the study. Results A total of 103 MSM cases of HIV-infected MSM were reported from 2005 to 2015 in Minhang District, with a late detection rate of 32.3%. Multivariate regression analysis showed that the incidence of other patients whose age was 50 years or older was higher than those of other groups (OR 95% CI, OR, 95% CI ) Were 12.31 (1.12 ~ 135.67) and 1.94 (1.08 ~ 3.50), respectively. Conclusion The late detection rate of MSM with HIV infection in Minhang District is high, and the age and sample source are the important influencing factors. HIV detection of MSM in middle-aged and elderly patients should be strengthened.
