A self-administered online structured questionnaire was used to collect data on sociodemographic information, sexual behaviors, gay app use, substance use, and HIV testing history. We performed multivariable log-binomial regression to assess correlates of seeking sex partners via gay apps. Results: A total of 447 MSM attending university with an average age of 20.4 (SD 1.5) years were recruited. Almost all participants (439/447, 98.2{\%}) reported gay app use at some point in their life, and 240/439 (53.7{\%}) reported ever seeking sex partners via gay apps. Blued (428/439, 97.5{\%}) was the most popular gay app. Higher proportions of sexual risk behaviors (including seeking sex partners via apps [P<.001], engaging in group sex [P<.001], having multiple sex partners [P<.001], unawareness of sex partners' HIV status [P<.001], and using recreational drugs during sex [P<.02]) were positively associated with the increase in the frequency of gay app use. In multivariable analysis, participants who used gay apps to seek sex partners might be more likely to have multiple sex partners in the past 3 months (adjusted prevalence ratio [APR] 1.53, 95{\%} CI 1.33-1.76; P<.001), engage in group sex in the past 3 months (APR 1.55, 95{\%} CI 1.35-1.78; P<.001), and have sex partners with unknown or positive HIV status (APR 1.72, 95{\%} CI 1.46-2.01; P<.001). Conclusions: Seeking sex partners via gay apps may associate with the increased high-risk sexual behaviors among MSM attending university. The causality between seeking sex partners via gay apps and increased high-risk sexual behaviors should be further investigated so as to inform potential policies for HIV prevention.
