深圳市龙岗区经性传播感染HIV-1的老年男性病例流行病学特征分析

Epidemiological characteristics of elderly male cases of sexually transmitted HIV-1 infection in Longgang district of Shenzhen city

目的分析深圳市龙岗区经性传播感染HIV-1的老年男性病例特征,为解决老年男性艾滋病干预问题提供适当的应对策略。方法资料来源于"传染病监测系统",时间截至2019年12月31日,深圳市龙岗区内登记的经性传播感染,年龄≥50岁的男性HIV-1病例,分析其流行病学特征。结果 756名老年男性HIV-1感染病例中,在婚占55.16%(417/756),省外户籍为主,初中及以下的学历占到64.15%(485/756);2010年之后病例报告数大幅上升,晚发现比例高;同性性传播占28.31%(214/756),异性性传播占71.69%(542/756),不同的报告时间(χ2=9.967,P=0.019)、年龄(χ2=23.990,P<0.001)、文化程度(χ2=42.957,P<0.001)、婚姻(χ2=6.928,P=0.031)、户籍(χ2=11.586,P=0.021)、职业(χ2=38.624,P<0.001)、性病史(χ2=29.545,P<0.001)、发现途径(χ2=137.172,P<0.001)、病程阶段(χ2=6.539,P=0.011)、是否接受CD4检测(χ2=18.268,P<0.001)等因素在同性和异性性传播方式构成比差异均有统计学意义。结论老年男性HIV-1感染病例快速增多,相关因素较为复杂,应该引起关注,采取必要的措施,控制HIV-1的蔓延。

Objective To analyze the characteristics of elderly male cases of sexually transmitted HIV-1 infection in Longgang district of Shenzhen city,and to provide corresponding coping strategies for AIDS intervention in elderly men.Methods The case data came from the Infectious Disease Surveillance System by the end of December 31,2019.We analyzed the epidemiological characteristics of male sexually transmitted HIV-1 infection cases aged≥50 years and registered in Longgang district of Shenzhen city.Results Among 756 elderly male cases of HIV-1 infection,the married accounted for 55.16%(417/756).Most of the cases came from other provinces.The cases with junior middle school education level or below accounted for 64.15%(485/756).The number of reported cases after 2010 increased significantly,and the proportion of late detection was high.Homosexual transmission accounted for 28.31%(214/756),while heterosexual transmission for 71.69%(542/756).Different reporting times(χ2=9.967,P=0.019),age(χ2=23.990,P<0.001),educational background(χ2=42.957,P<0.001),marriage(χ2=6.928,P=0.031),household registration(χ2=11.586,P=0.021),occupation(χ2=38.624,P<0.001),history of sexually transmitted diseases(χ2=29.545,P<0.001),way of discovery(χ2=137.172,P<0.001),stage of disease(χ2=6.539,P=0.011),and receiving CD4 test or not(χ2=18.268,P<0.001)showed statistically significant differences in the constituent ratios of homosexual and heterosexual transmission.Conclusions The number of elderly male HIV-1 infection cases is increasing rapidly,and the related factors are more complicated.We should be concerned about elderly male HIV-1 infections and take necessary measures to control the spread of HIV-1 infection.
