摘要:
目的 了解通过社交软件线上干预动员MSM参与线下HIV检测的效果,并调查分析线下接受检测者的特征。 方法 分析比较通过不同社交软件线上所接触动员人数与线下实际检测人数,描述线下接受检测的MSM人群特征,并对感染风险高、低分组的MSM特征差异进行比较。 结果 线上干预动员MSM参与线下检测比例为23.78% (229/963),使用Blued动员线下检测比例高于其他社交软件(χ2=3.958,P=0.047),总动员比为100∶2.4,总动员效率为1.01人/d。220名有肛交性行为的MSM根据是否坚持使用安全套分为高危行为组(n=96)与低危行为组(n=124),高危组的梅毒知识知晓合格比例低于低危组(χ2=6.308,P=0.009),而HIV检测阳性结果的比例高于低危组(χ2=11.299,P=0.001)。 结论 使用社交软件线上干预动员线下检测能有效接触HIV感染风险较高的MSM和及时发现已感染的病例,在运用社交软件与目标人群建立联系并互动时,主动接触比被动响应更能提高MSM应答的比例。 Abstract:Objective To understand the effectiveness of the online intervention to mobilize men who have sex with men (MSM) to participate in offline HIV testing through social networking applications, and to investigate and analyze the characteristics of offline test participants. Methods We analyzed and compared the number of MSM online contacted through different social networking applications with the number actually tested offline. Then, we characterized the MSM tested offline as well as to compare the differences in the characteristics of MSM in high and low risk groups of infection. Results The online intervention mobilized 23.78% of MSM to participate in offline testing (229/963), with a higher percentage of offline testing recruited using Blued than other social networking applications (χ2=3.958, P=0.047). The total recruitment ratio was 100:2.4, and A total recruitment efficiency was 1.01 persons/day. A total of 220 MSM who had anal sex were divided into a high-risk behavior group (n=96) versus a low-risk behavior group (n=124) based on whether or not they consistently used condoms. The percentage of qualified syphilis knowledge in the high-risk group was lower than in the low-risk group (χ2=6.308, P=0.009), while the percentage of positive HIV test results was higher than in the low-risk group (χ2=11.299, P=0.001). Conclusions Using social networking applications to mobilize MSM to participate in offline testing were effective in reaching groups at higher risk of HIV infection, as well as in detecting infected cases timely. When communicating and intervening with the target population online, proactive contact increased the proportion of MSM responding more than passive reply. -
