2017—2019年浙江省温州市经性传播感染的HIV/AIDS感染来源及特征分析

目的分析2017—2019年浙江省温州市经性传播感染的HIV/AIDS感染来源和特征,为艾滋病综合防治措施的调整提供依据。方法以2017—2019年温州市鹿城区和永嘉县新发现的经性传播感染的HIV/AIDS为研究对象,调查收集其人口学、性行为、流动情况等信息,并采血检测首次CD4^(+)T淋巴细胞计数,运用Epi Data 3.1和SAS大学版软件进行数据整理和统计分析。结果 342名调查对象以男性、25~59岁年龄段为主,未婚、初中及以下文化程度、外地迁入者居多。经感染来源判定,新感染比例为22.42%,本地感染比例为71.00%。15~24岁以下年龄组、未婚病例新感染比例高,分别为33.33%和31.54%;60岁及以上年龄组、教师/干部/退休等职业、大专及以上文化程度病例本地感染比例高,分别为94.74%、87.80%和81.43%;新感染病例曾发生非商业临时异性性行为、固定性伴同性性行为的比例分别为60.87%和39.53%,高于既往感染病例(χ^(2)=3.967,P=0.047;χ^(2)=4.314,P=0.038);本地感染病例曾发生非商业临时同性性行为比例为98.26%,高于外地感染病例(P=0.036)。结论 2017—2019年温州市经性传播感染的HIV/AIDS以既往感染和本地感染为主,青年、老年及高知人群不容忽视,应加强对非商业临时性行为的干预。

Infection source and characteristics of sexually transmitted HIV/AIDS cases in Wenzhou City,Zhejiang Province, 2017-2019

Objective To analyze the infection source and characteristics of sexually transmitted HIV/AIDS cases in Wenzhou City, Zhejiang Province during 2017-2019, and to provide a basis for adjustment of AIDS comprehensive prevention and control measures. Methods Newly reported HIV/AIDS cases in Lucheng District and Yongjia County in Wenzhou City from 2017 to 2019 served as the study subjects. Their information about demography, sexual behavior and migration was surveyed and collected, and then their blood samples were detected for initial CD4⁺ T-lymphocyte count. All the data were collected by Epi Data 3.1software, and analyzed by SAS university edition. Results There were 342 HIV/AIDS cases investigated. Most cases were male, aged between 25 and 59 years, unmarried, with an educational background of junior middle school or below, and migrants. Through judging their infection sources, the proportions of new infection cases and local infection cases were 22.42% and 71.00%, respectively. The new infection cases were found to be higher in the group under 15-24 years old and the unmarried, with the proportions of 33.33% and 31.54%, respectively. The local infection cases were found to be higher in the group aged 60 years and above, teachers/cadres/retirees, and the group with an educational background of college degree or above, with the proportions of 94.74%, 87.80% and 81.43%, respectively. The proportions of new infection cases with non-commercial temporary heterosexual behavior and homosexual behavior with fixed sexual partner were 60.87% and 39.53%, respectively, which were higher than thosein previous infection cases (χ²=3.967, P=0.047; χ²=4.314, P=0.038). The proportion of local infection cases with non-commercial temporary homosexual behavior was 98.26%, which was higher than that in non-local infection cases (P=0.036). Conclusion The sexually transmitted HIV/AIDS cases in Wenzhou City from 2017 to 2019 were mainlyassociated with previous and local infections. We should pay attention to youths, the elderly and highly educated personnel, and enhance interventions on non-commercial temporary sexual behavior.
