摘要
目的分析2017—2020年宁波市新报告人类免疫缺陷病毒(human immunodeficiency virus,HIV)感染者和获得性免疫缺陷综合征(acquired immunodeficiency syndrome,AIDS)患者(HIV感染者/AIDS患者)新近感染特征及其影响因素,为探索降低HIV新近感染措施提供依据。方法选取2017—2020年宁波市新报告HIV感染者/AIDS患者作为研究对象,采用个案调查问卷面对面收集研究对象一般人口学信息、性行为特征、HIV抗体检测及HIV感染途径等相关信息。结果共完成调查335例,研究对象平均年龄为(36.64±14.31)岁,其中男性293例(87.46%)、未婚168例(50.15%)、本地户籍210例(62.69%)、文化程度初中及以下158例(47.16%)、在本市居住时间>5年131例(39.10%)。HIV感染者/AIDS患者新近感染186例(55.52%),其中本地感染的HIV感染者/AIDS患者新近感染143例(62.45%),男男同性性行为传播感染的HIV感染者/AIDS患者新近感染120例(68.57%)。多因素分析显示,是否本地感染、年龄、感染途径和确证前是否做过HIV检测是HIV感染者/AIDS患者新近感染的影响因素(P<0.05)。结论2017—2020年宁波市新报告HIV感染者/AIDS患者感染时间以新近感染为主,本地感染、低年龄组(<50岁)和男男同性性行为传播是HIV感染者/AIDS患者新近感染的危险因素,需针对经交友软件寻找性伴等特定高危人群开展溯源调查,以查明并控制本地AIDS新近感染风险。
Objective To discuss the epidemiological characteristics and influencing factors of newly reported HIV/AIDS in Ningbo from 2017 to 2020,and to provide a basis for exploring measures to reduce HIV infections.Methods The newly reported HIV/AIDS cases in Ningbo from 2017 to 2020 were recruited in the study and a face to face questionnaire survey was conducted to collect relevant information including demography,sexual behavior,HIV antibody test and infection routes of study subjects.Results A total of 335 cases completed the survey.The mean age of the study subjects was(36.64±14.31)years old.293 cases were men(87.46%)and 168 were unmarried(50.15%),210(62.69%)were local residents and 158(47.16%)had junior high school and lower education level.131 cases(39.10%)lived in the city for more than 5 years.The newly infected rate of HIV/AIDS was 55.52%(186/335),62.45%(143/229)were locally infected and 68.57%(120/175)were men who have sex with men.Multivariate analysis showed that local infection,age,routes of infection and HIV testing before diagnosis were the major influencing factors of new HIV/AIDS infection(P<0.05).Conclusions The newly reported HIV/AIDS cases in Ningbo from 2017 to 2020 are mainly new infections.Local infection,younger age(<50 years old)and same-sex transmission are the risk factors for new HIV/AIDS infections.It is necessary to conduct traceability investigations for specific high-risk groups such as these who finds sex partner through dating software to identify and control the risk of local HIV infection.
