目的对比网络调查的男男性行为者(MSM)行为数据和全国哨点监测的MSM行为数据的差异。方法通过MSM社交网站及手机APP招募目标人群完成网络调查,与国家哨点监测结果进行对比。网络问卷内容参照国家哨点监测问卷,调查时间也与国家哨点监测工作时间相符。结果网络调查共收集14 757份有效问卷。活跃于网络和手机APP的MSM与哨点监测MSM相比,教育程度高(63.3%vs.43.1%),未婚者居多(91.4%vs.24.3%),且最近1年内的HIV检测比例低(26.4%vs.46.8%)。结论与哨点监测MSM结果相比,网络调查MSM在一般人口学特征和艾滋病感染危险行为方面存在差异,如果哨点监测数据能结合网络调查行为学数据综合分析,能提供更加准确的信息。
PURPOSE To compare the difference between MSM behavioral data from online surveys and MSM behavioral data from nationwide sentinel surveillance. Methods We recruited the target population through MSM social networking sites and mobile APP to complete the online survey and compare them with the national sentinel surveillance results. The content of the online questionnaire refers to the national sentinel surveillance questionnaire, and the investigation time is also consistent with the national sentinel surveillance work time. Results A total of 14,757 valid questionnaires were collected through the web-based survey. MSM active in the web and mobile apps had a higher level of education (63.3% vs.43.1%), unmarried majority (91.4% vs.24.3%) and a lower proportion of HIV testing in the recent year compared to sentinel surveillance MSM 26.4% vs.46.8%). Conclusion Compared with the results of sentinel surveillance MSM, there are differences between general demographic characteristics and HIV risk behaviors in sentinel surveillance MSM. If the sentinel surveillance data can be combined with comprehensive analysis of network survey behavioral data, it can provide more accurate information.
