Abstract

Objective To understand the epidemiological characteristics of newly reported human immunodeficiency virus (HIV) infection/acquired immunodeficiency syndrome (AIDS) among the population aged ≥50 years in Pengzhou City of Sichuan Province during 2014–2018 and provide theoretical basis for comprehensive prevention and control of AIDS

Methods The AIDS surveillance data of the population aged ≥50 years in Pengzhou City during 2014–2018 was collected from national AIDS prevention and treatment information system, and analyzed to know their distribution characteristics, transmission routes and sample sources.

Results A total of 825 cases were reported during the study period. The proportion of HIV/AIDS cases aged ≥50 years old accounted for the total number of new reported cases every year, the lowest in 2014 (51.2%) and the highest in 2018 (73.1%). The most reported cases were in the age group of 50-<60-year-old, accounting for 40.5%;males were more than females; marital status was dominated by married couples, accounting for 61.8%; occupation was dominated by farmers, accounting for 85.0%; educational level was dominated by primary schools and below, accounting for 58.0%; the main route of infection was heterosexual transmission, accounting for 98.3%. The main source of case report was found in medical institutions, accounting for 81.0%, followed by CDC, accounting for 18.0%.

Conclusion The number and proportion of reported HIV/AIDS cases aged ≥50 years old in Pengzhou are increasing year by year. Heterosexual contact is the main route of transmission and the detection of medical institution is the main way for case finding. We should focus on the sexual health of the population aged ≥50 years, and adopt health education and prevention interventions according to their behavioral and psychological characteristics, formulate relevant supporting policies for testing, and continue to increase the intensity of testing.

摘要： 目的 分析四川省彭州市2014—2018年新报告的≥50岁艾滋病病毒感染者/艾滋病病人(HIV/AIDS)流行特点，为彭州市有针对性开展艾滋病综合防控工作提供理论依据。 方法通过全国艾滋病防治基本信息系统收集彭州市2014—2018年≥50岁人群艾滋病疫情报告资料，对病例分布特点、传播途径构成以及检测发现途径等进行分析。 结果2014—2018年共报告825例≥50岁HIV/AIDS,每年新报告病例占当年新报告病例总数的比例2014年最低(51.2%),2018年最高(73.1%)。报告病例以50~<60岁年龄组为最多，占40.5%;男性多于女性;婚姻状况以巳婚有配偶为主，占61.8%;职业以农民为主，占85.0%;文化程度以小学及以下为主，占58.0%;感染途径以异性传播为主，占98.3%。病例报告来源以医疗机构检测发现为主，占81.0%，其次为疾控机构检测，占18.0%。 结论彭州市≥50岁HIV/AIDS的报告病例数和构成比均呈逐年增加趋势，异性性接触为主要传播途径，医疗机构检测为主要发现途径，应重点关注≥50岁人群性健康，有针对性地采取符合其行为和心理特点的健康教育预防干预措施，制定检测相关支持政策，继续加大检测力度。
