摘要
目的了解我国2015—2019年新报告≥50岁异性传播艾滋病感染者/患者(HIV/AIDS)的性别比特征。方法通过艾滋病综合防治信息系统收集我国2015—2019年新诊断发现、诊断年龄≥50岁且经异性传播感染的HIV/AIDS,分析不同诊断年龄、感染方式的男女性别比差异。结果2015—2019年我国新报告≥50岁异性传播HIV/AIDS由2015年29765例增至2019年60591例,其中经配偶/固定性伴感染占比由2015年12.7%减少至2019年10.6%,商业性伴及非商业临时性伴构成比维持在较高水平,均值分别为46.0%、39.5%。随诊断年龄增加,报告病例性别比由50~59岁组1.8增加至60~69岁组2.5、≥70岁组6.8。分不同感染方式,经商业性伴感染病例和经非商业临时性伴感染者的性别比分别由50~59岁组的10.4和1.1增至≥70岁组的58.7(Z=38.31,P<0.001)和3.4(Z=51.49,P<0.001),经配偶/固定性伴感染的性别比稳定于0.2~0.4。结论我国报告≥50岁异性传播HIV/AIDS中不同诊断年龄、感染方式的性别比存在差异。需扩大高风险人群检测、治疗及综合行为干预工作,结合分子流行病学探索≥50岁人群HIV传播链,提高病例发现效率。
Objective To understand sex ratio of newly reported people living with HIV/AIDS(PLWHA)aged≥50 years and infected through heterosexual contact in China during 2015 and 2019.Methods The data of newly reported PLWHA aged≥50 years and infected through heterosexual contact in China from 2015 to 2019 were collected from the China Information System for Disease Control and Prevention.Sex ratios of the PLWHA were analyzed in terms of diagnosis age and infection mode.Results From 2015 to 2019,the number of newly reported PLWHA aged≥50 years and infected through heterosexual contact increased from 29765 to 60591.Among them,the proportion of those infected through sex with spouse/regular partners decreased from 12.7%to 10.6%,while the proportions of those infected through commercial and noncommercial casual sex remained at high levels(46.0%and 39.5%averagely).Τhe sex ratios of the PLWHA increased from 1.8 in 50-59 year age group to 2.5 in 60-69 year age group and 6.8 in≥70 year age group.With the increase of diagnosis age,sex ratios of the PLWHA infected through commercial and non-commercial casual sex increased from 10.4 and 1.1 in 50-59 year age group to 58.7(Z=38.31,P<0.001)and 3.4(Z=51.49,P<0.001)in≥70 year age group respectively,but the sex ratio of those infected through sex with spouse/regular sexual contact remained at 0.2-0.4.Conclusion In China,the differences in sex ratio existed in the reported PLWHA aged≥50 years and infected through heterosexual contact in different age groups and infection mode groups.It is suggested to expand HIV testing,treatment and integrated behavioral intervention for high-risk populations,and utilize molecular epidemiology to explore HIV transmission chain in people aged≥50 years to improve the efficiency of case detection.
