男男性行为者网络调查与全国哨点监测调查的比较研究

A comparison of web-based survey and national sentinel surveillance among MSM in China

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。
