【摘要】 目的 了解男男同性性行为人群（men who have sex with men,MSM）中人类免疫缺陷病毒（human immunodeficiency virus,HIV）检测频率及影响因素。方法 采用同伴推动抽样（respondent-driven sampling, RDS）法招募MSM，进行面对面问卷调查。采用趋势χ2检验和有序logistic回归模型分析HIV检测频率的影响因素。结果 招募MSM 608人，70.93%的MSM最近一年检测过HIV,44.14%检测≥2次。月收入5 000～<10 000元者提升一个等级检测频率的可能性是月收入<5 000元者的1.60倍（95%CI:1.03～2.47），最近半年性伴数为≥10人者提升一个等级检测频率的可能性是1个性伴者的2.85倍（95%CI:1.46～5.59）, 1年内接受过同伴教育者提升一个等级检测频率的可能性是未接受者的3.94倍（95%CI:2.39～6.49）。结论 MSM中HIV检测频率仍需提高，应加强与社会组织合作，提供多种便捷、无歧视的检测服务。更多还原

【Abstract】 Objective To understand the frequency of human immunodeficiency virus(HIV) testing and its influencing factors among men who have sex with men(MSM). Methods Respondent-driven sampling(RDS) method was used to recruit MSM for a face-to-face interview with a structured questionnaire. The factors associated with the frequency of HIV testing(0, 1, and ≥2 in the prior year) were analyzed using trend chi-square test and ordinal logistic regression.Results A total of 608 MSM were recruited, of whom 70. 93% had received HIV testing in the last year, and 44. 14% had been tested twice or more than twice. Those with a monthly income of 5 000-< 10 000 yuan were 1. 60(95%CI: 1. 03-2. 47) times more likely to have a higher frequency of HIV testing than those with a monthly income <5 000 yuan; those having ≥10 sexual partners in the last six months were 2. 85(95%CI: 1. 46-5. 59) times more likely to have HIV testing more frequently compared with those having one sexual partner; and those having received peer education in the past year were 3. 94(95%CI: 2. 39-6. 49) times more likely to have a higher frequency of HIV testing compared with those who had not received peer education. Conclusions The frequency of HIV testing in the MSM population in Beijing needs to be further increased. Cooperation with social organizations should be strengthened to provide a variety of convenient and non-discriminatory testing services.更多还原
