To evaluate the acceptability and effectiveness of a pilot intervention programme using gay geosocial mobile applications (apps) to offer rapid HIV and other STI tests to men who have sex with men (MSM) in Barcelona between December 2015 and March 2016.
We offered rapid HIV, syphilis and hepatitis C testing by sending private messages on apps for sexual and social encounters. Acceptance was defined as the proportion of users who favourably responded to the message and effectiveness was defined as the proportion of users who attended our facilities among those who were interested in attending. To identify variables associated with the response to the messages, multivariate logistic regression was used. Adjusted OR (OR) and 95% CIs were calculated. We collected information on sociodemographics, sexual behaviours and app usage from the contacted user profiles and from users who attended our facilities. A descriptive analysis was carried out.
2656 individual messages were sent. Overall, a 38.4% response rate was obtained, 83.0% of them found it acceptable to receive the unsolicited message, and 73.2% effectiveness was obtained. Responders had higher odds of being 45 years or older (OR=1.48; 95% CI 1.06 to 2.08), being connected at the moment the message was sent or during the previous hour (OR=1.92; 95% CI 1.38 to 2.68), having a profile photo not exposing bare chest or abdomen (OR=1.44; 95% CI 1.07 to 1.92) and using the Grindr app (OR=1.39; 95% CI 1.12 to 1.73). Of those who were tested and took the survey (n=77), 45.5% had not taken an HIV test in over a year, 24.7% had had a previous STI diagnosis, 51.4% had reported anal sex without condom and 52% had consumed alcohol or drugs for sex.
The response rate, acceptance and effectiveness observed in this study indicate that this strategy could be a useful tool for promoting STI testing among high-risk MSM population.
评估 2015 年 12 月至 2016 年 3 月期间，在巴塞罗那利用同志社交移动应用（app）向男男性接触者（MSM）提供快速 HIV 和其他性传播感染（STI）检测的试点干预项目的可接受性和效果。
我们通过向性接触和社交的 app 发送私人消息，提供快速 HIV、梅毒和丙型肝炎检测。接受度定义为赞成消息的用户比例，效果定义为对参加检测感兴趣的用户中实际参加的比例。为了确定与消息响应相关的变量，我们使用多变量逻辑回归。计算调整后的比值比（OR）和 95%置信区间（CI）。我们从联系的用户资料和参加我们机构的用户收集社会人口学、性行为和应用程序使用信息。进行描述性分析。
共发送了 2656 条个人消息。总体而言，我们获得了 38.4%的回复率，其中 83.0%的人认为收到不请自来的消息是可以接受的，效果为 73.2%。回复者更有可能是 45 岁或以上（OR=1.48；95%CI 1.06 至 2.08），在发送消息时或前一个小时处于连接状态（OR=1.92；95%CI 1.38 至 2.68），个人资料照片没有暴露胸部或腹部（OR=1.44；95%CI 1.07 至 1.92），并且使用 Grindr 应用程序（OR=1.39；95%CI 1.12 至 1.73）。在接受检测并参加调查的 77 人中，45.5%的人在过去一年中没有接受过 HIV 检测，24.7%的人以前曾被诊断出患有性传播感染，51.4%的人曾报告过无保护的肛交，52%的人曾为了性而饮酒或吸毒。
本研究中观察到的回复率、接受度和效果表明，这种策略可能是促进高危 MSM 人群进行性传播感染检测的有用工具。
