| 摘要: |
| 目的 了解我国西部地区男男性接触者（MSM）最近1年人类免疫缺陷病毒（HIV）检测比例及其影响因素。方法 在重庆及四川地区部分城市采用来自多个地区和途径的方便抽样，共招募1245例MSM。调查对象通过匿名的自填式问卷完成调查并同时接受现场HIV检测，采用logistic回归模型对该地区MSM近1年HIV检测行为的影响因素进行分析。结果 调查完成问卷1245份，有效问卷1199份（96.31%）。调查中最近1年HIV检测比例为43.45%（521/1199）；HIV抗体阳性检出率为21.35%（256/1199），其中近1年没有做过HIV检测者中HIV抗体阳性检出率（24.93%）高于检测者（16.70%），差异具有统计学意义（χ2=11.8763，P=0.0006）。多因素logistic回归分析结果显示，艾滋病相关知识得分>10分（OR=1.593，95%CI：1.164~2.180）是MSM近1年参与HIV检测的促进因素，而既往未做过艾滋病主动咨询（OR=0.284，95%CI：0.218~0.371）、自认为所生活的市/区/县的“同志”人群感染艾滋病的比率低（OR=0.570，95%CI： 0.386~0.841）、最近6个月与男性肛交时偶尔使用或从不使用安全套（OR=0.688，95%CI： 0.514~0.919；OR=0.645，95%CI：0.421~0.987）是阻碍因素。结论 西部地区MSM人群近1年HIV检测比例较低，而整体HIV感染率较高，且近1年未接受HIV检测的MSM具有更高的HIV感染风险。应继续深入加强以“同志”社区为基础的艾滋病感染风险教育，进一步提高艾滋病高流行地区MSM人群定期主动HIV检测的比例，有效控制艾滋病流行。 |

| Abstract: |
| Objective To know about the prevalence of recent human immunodeficiency virus (HIV) testing (in the last 12 months) and its associated factors among men who have sex with men (MSM) in western China. Methods A total of 1 245 MSM were recruited by convenient sampling from multiple sources and areas in Chongqing and Sichuan regions. The participants were interviewed with anonymous self-administered questionnaire and received HIV testing at the same time. Multivariate logistic regression was used to identify the factors associated with recent HIV testing behavior. Results A total of 1 245 questionnaires were completed, and 1 199 (96.31%) were valid and included for analysis. Of the 1 199 MSM, 43.45% (521/1 199) reported having HIV testing in recent one year. The overall HIV antibody positive rate was 21.35% (256/1 199) in the present study; the HIV positive rate was significantly higher in those did not receive HIV testing in recent one year compared with those received HIV testing (24.93% vs 16.70%, χ2=11.876 3,P=0.000 6). Logistic regression analysis revealed that a score >10 in HIV/AIDS knowledge test (OR=1.593, 95%CI:1.164-2.180) was associated with increased recent HIV testing among MSM, and the factors associated with lower HIV testing rate in recent one year included not receiving free HIV counseling voluntarily over past years (OR=0.284, 95%CI:0.218-0.371), self-perceived low prevalence of HIV infection among MSM in city/district/county they were living (OR=0.570, 95%CI:0.386-0.841), and occasionally/never using condoms during anal sex with men in recent six months (OR=0.688, 95%CI:0.514-0.919; OR=0.645, 95%CI:0.421-0.987). Conclusion The proportion of recent HIV testing among MSM in western China is low, although the HIV prevalence is still alarmingly high. MSM not receiving any HIV testing in recent one year have higher HIV infection risk compared with those receiving. The community-based HIV-related risk education should be strengthened so as to further promote regular HIV testing among MSM in these high epidemic areas. |
