Although community-based strategies have been shown to increase HIV testing uptake, the relative effectiveness of mobile social media promotion compared with volunteer-driven recruitment remains underexplored. Limited research has investigated how these strategies differentially affect MSM who have not undergone previous HIV testing.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>This study aimed to compare the differences between a mobile social media promotion strategy and a volunteer-driven strategy for community organizations to recruit MSM for HIV testing.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A cross-sectional study was conducted from July to December 2023 among MSM in Zhejiang Province, China. Participants aged 16 years with an HIV-negative or unknown status were recruited either through a mobile social media promotion strategy or through a volunteer-driven strategy by a community organization. They completed a questionnaire that collected information on demographics, sexual behavior, and HIV testing history. All participants were tested for HIV after completing the questionnaire. A multivariate logistic regression model was used to identify factors associated with recruitment through mobile social media promotion.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The study included 4600 MSM, of whom 3035 (66%) were recruited through the mobile social media strategy. Overall, 1.4% (66\/4600) of participants tested positive for HIV, and 18.8% (865\/4600) underwent HIV testing for the first time. Recruitment via the mobile social media promotion strategy was significantly associated with several factors: having only gay sexual partners (adjusted OR [aOR] 1.23, 95% CI 1.05-1.45), having more than 2 sexual partners in the past 3 months (aOR 1.74, 95% CI 1.42-2.11), frequently using rush poppers during sex (aOR 1.39, 95% CI 1.14-1.99), having a history of sexually transmitted infections (aOR 1.56, 95% CI 1.02-2.39), having awareness of pre-exposure prophylaxis (aOR 1.42, 95% CI 1.19-1.71), having awareness of postexposure prophylaxis (PEP; aOR 1.49, 95% CI 1.24-1.79), using mail-in HIV self-testing kits (aOR 2.02, 95% CI 1.77-2.31), testing HIV-positive (aOR 2.02, 95% CI 1.10-3.72), and first-time HIV testing (aOR 1.28, 95% CI 1.09-1.52).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Community organizations play a critical role in expanding HIV testing and identifying undiagnosed individuals infected with HIV. Compared to the volunteer-driven outreach, mobile social media promotion strategies had a higher proportion of first-time testers and a higher rate of HIV positivity. We recommend prioritizing mobile social media strategies in regions with limited LGBTQ+ organizations or HIV health services to increase HIV testing coverage and interventions among MSM.<\/jats:p>\n
