To investigate the relationship between gay app use and HIV testing among men who have sex with men (MSM).
Serial cross-sectional study.
A newly well-developed city in China.
4935 MSM were recruited through offline sampling methods from 2015 to 2017.
The primary outcome is the difference in HIV testing between app and non-app users.
2872 (58.2%) and 2159 (43.7%) participated MSM had been tested for HIV within lifetime and the past year, respectively. Compared with non-app-using MSM, app-using MSM had a significantly higher prevalence of HIV testing within lifetime (adjusted OR (AOR): 1.48, 95% CI 1.27 to 1.72) and the past year (AOR: 1.36, 95% CI 1.18 to 1.57). App-using MSM were more likely to take an HIV test at the Centers for Disease Control and Prevention (AOR: 1.48, 95% CI 1.24 to 1.76) and community-based organisations (AOR: 1.71, 95% CI 1.44 to 2.03), but less often at gay venues (AOR: 0.49, 95% CI 0.37 to 0.63). Meanwhile, app-using MSM were more likely to take self-testing (AOR: 1.61, 95% CI 1.21 to 2.14). Predictors of HIV testing in the past year were: having an education level of college or higher (AOR: 1.29, 95% CI 1.01 to 1.65), being self-identified as a homosexual (AOR: 1.23, 95% CI 1.02 to 1.46), being recruited through clinic-based sampling (AOR: 1.30, 95% CI 1.06 to 1.60), using gay app (AOR: 1.49, 95% CI 1.21 to 1.83), engaging in group sex (AOR: 1.64, 95% CI 1.23 to 2.19), having received HIV-related service (AOR: 5.49, 95% CI 4.57 to 6.60), having a high level of HIV-related knowledge (AOR: 1.33, 95% CI 1.10 to 1.61) and high-risk perception (AOR: 2.95, 95% CI 1.40 to 6.23).
Gay app use was significantly associated with increased HIV testing among MSM hard to reach by traditional outreach. Therefore, it is imperative to expand HIV testing among non-app-using MSM. Continued efforts, innovative strategies and increased resource are highly needed to realise the first '90' target.
调查男男性行为者（MSM）使用同性恋应用程序与 HIV 检测之间的关系。
连续横断面研究。
中国一个新开发的城市。
2015 年至 2017 年期间，通过线下抽样方法招募了 4935 名 MSM。
分别有 2872（58.2%）和 2159（43.7%）名参与者在有生之年和过去一年接受过 HIV 检测。与非应用程序使用者相比，应用程序使用者在有生之年（调整后的 OR（AOR）：1.48，95%CI 1.27 至 1.72）和过去一年（AOR：1.36，95%CI 1.18 至 1.57）接受 HIV 检测的比例显著更高。使用应用程序的 MSM 更有可能前往疾病预防控制中心（AOR：1.48，95%CI 1.24 至 1.76）和社区组织（AOR：1.71，95%CI 1.44 至 2.03）接受 HIV 检测，但前往同性恋场所的可能性较小（AOR：0.49，95%CI 0.37 至 0.63）。同时，使用应用程序的 MSM 更有可能进行自我检测（AOR：1.61，95%CI 1.21 至 2.14）。过去一年 HIV 检测的预测因素包括：具有大学或以上学历（AOR：1.29，95%CI 1.01 至 1.65）、自我认同为同性恋者（AOR：1.23，95%CI 1.02 至 1.46）、通过诊所抽样招募（AOR：1.30，95%CI 1.06 至 1.60）、使用同性恋应用程序（AOR：1.49，95%CI 1.21 至 1.83）、从事团体性行为（AOR：1.64，95%CI 1.23 至 2.19）、接受过 HIV 相关服务（AOR：5.49，95%CI 4.57 至 6.60）、具有较高的 HIV 相关知识水平（AOR：1.33，95%CI 1.10 至 1.61）和高风险感知（AOR：2.95，95%CI 1.40 至 6.23）。
同性恋应用程序的使用与传统外展难以接触到的 MSM 中 HIV 检测的增加显著相关。因此，扩大非应用程序使用者的 HIV 检测势在必行。需要继续努力，创新战略，并增加资源，以实现第一个“90”目标。
