1997 - 2018年贵州省50岁及以上HIV/AIDS病例特征分析

目的 分析贵州省≥50岁艾滋病病毒感染者/艾滋病患者（HIV/AIDS）人口学、行为特征。方法 通过《艾滋病防治基本信息系统》下载截止到2018年贵州省报告的全部≥50岁HIV/AIDS病例资料以及专项调查数据进行分析。结果 截止到2018年12月31日，贵州省共报告≥50岁HIV/AIDS 17 961例，90.0%为异性传播，病例构成比从2010年的12.6%上升到2018年的48.1%，呈快速增长的趋势（χ2趋势 = 4 835.43,P＜0.001）；病例主要通过医疗机构检测发现、呈现逐年上升的趋势（ χ2趋势 = 5 396.46,P＜0.001），但病例晚发现比例高达85.3%，分析显示男性、≥60岁、通过其他就诊者检测来源病例的晚发现率较高；658例≥50岁男性HIV/AIDS专题调查发现，近期和远期非婚商业异性性行为和非婚非商业异性性行为发生率均较高，安全套使用比例偏低，且存在不安全的医疗行为。结论 贵州省≥50岁HIV/AIDS病例近年快速增长，一方面应积极探索有效的干预手段控制这一群体艾滋病的感染；另一方面应扩大这一群体HIV检测的覆盖面，减少病例的晚发现。

Analysis on the characteristics of HIV/AIDS case aged 50 and above in Guizhou province from 1997 to 2018

The study aimed to analyze the demographic and behavioral characteristics of HIV/AIDS cases aged 50 and above in Guizhou province. Methods Through the National Information System for Comprehensive AIDS Prevention and Control, all HIV/AIDS cases aged 50 and above reported in Guizhou province by 2018 were downloaded and analyzed with the data of special investigation. Results A total of 17,961 HIV/AIDS aged 50 and above years were reported in Guizhou province until December 31 th 2018, 90.0% of which were heterosexual transmission. The proportion of cases increased from12.6% in 2010 to 48.1% in 2018, showing a rapid growth trend(χ2trend=4835.43, P<0.001). The cases were mainly diagnosed by medical institutions and showed an increasing trend year by year(χ2trend=5396.46, P<0.001), but the late diagnosis rate of cases was as high as 85.3%. Multivariate analysis showed that the late diagnosis rate of cases of males, ≥60 years old and diagnosed by other patients was higher. Besides, a special investigation on 658 HIV/AIDS patients aged 50 and above found that the incidence of short-term and long-term heterosexual non-marital commercial sex and non-marital non-commercial heterosexual sex was high, the proportion of condom use was relatively low, and there were unsafe medical practices.Conclusion The number of HIV/AIDS cases aged 50 and above in Guizhou province has been increasing rapidly in recent years. On the one hand, effective intervention means should be actively explored to control the infection of AIDS in this group. On the other hand, the coverage of HIV test in this group should be expanded to reduce the late diagnosis of cases.
