摘要
目的分析男男性行为者(men who have sex with men,MSM)人类免疫缺陷病毒(human immuno?deficiency virus,HIV)检测服务利用特征及影响因素,为优化检测和预防策略提供依据。方法采用横断面研究设计,基于2019—2023年某社会组织HIV检测点22967例MSM人群的检测数据,分析检测服务利用特征、影响因素及已婚和学生人群感染风险特征。结果2019—2023年共纳入有效调查对象22967例。调查对象年龄(29.83±7.47)岁,累计检出HIV阳性497例(2.16%)。2019—2023年HIV检测量从8568例降至3332例,HIV阳性率从2.51%(215/8568)降至1.29%(43/3332),差异有统计学意义(χ^(2)=18.658,P<0.01)。18~<25岁(151/5497,2.75%)、高中及以下学历(152/4325,3.51%)、月收入3000~<5000元(126/3196,3.94%)、外省户籍(401/14986,2.68%)人群感染率较高。不规范使用安全套(227/6145,3.69%)和群体性行为(62/1797,3.45%)为主要危险因素。已婚MSM构成比从14.92%(1278/8568)上升至16.36%(545/3332),但感染率下降,从2.27%(29/1278)降至0.55%(3/545),学生MSM表现出较好的预防行为特征(HIV阳性率为1.52%,36/2368)。结论MSM人群HIV检测服务利用呈现检测量减少、阳性率下降及人群结构变化的新特征,应加强对年轻人、流动人口等重点人群的针对性干预。
Objective To analyze the utilization patterns of HIV testing services among men who have sex with men(MSM)and the influencing factors,and to provide a basis for optimizing testing and prevention strategies.Methods A cross-sectional study design was employed,analyzing testing data from 22967 MSM individuals collected by a community-based organization between 2019 and 2023.The study examined utilization characteris-tics,influencing factors,and infection risk profiles among married and student populations.Results A total of 22967 valid survey subjects were included from 2019 to 2023.The average age of the participants was 29.83±7.47 years,with 497 HIV-positive cases identified(2.16%).The number of HIV tests conducted decreased from 8568 in 2019 to 3332 in 2023,while the HIV positivity rate declined from 2.51%(215/8568)to 1.29%(43/3332),with a statistically significant difference(χ^(2)=18.658,P<0.01).Higher infection rates were ob-served in individuals aged 18-<25 years(151/5497,2.75%),those with a high school education or lower(152/4325,3.51%),monthly incomes between 3001 and<5000 yuan(126/3196,3.94%),and non-local residents(401/14986,2.68%).Major risk factors included inconsistent condom use(227/6145,3.69%)and group sexual behavior(62/1797,3.45%).The proportion of married MSM increased from 14.92%(1278/8568)to 16.36%(545/3332),yet their infection rate decreased from 2.27%(29/1278)to 0.55%(3/545).Student MSM exhibited better preventive behavioral characteristics,with an HIV positivity rate of 1.52%(36/2368).Conclusions The utilization of HIV testing services among MSM shows new characteristics,including a decrease in testing volume,a decline in positivity rates,and changes in population structure.Targeted interventions for key populations,such as young individuals and migrant populations,should be strengthened.
