Geosocial networking applications (GSN apps) are widely utilized by gay, bisexual, and other men who have sex with men (GBMSM) to meet potential sexual/romantic partners, foster friendships, and build community. However, GSN apps usage has been linked to elevated levels of HIV sexual risk behavior among GBMSM. Little is known about how GSN apps can facilitate HIV sexual risk behaviors, especially among GBMSM in Africa. To fill this gap in research, the present study aimed to characterize the frequency of GSN apps usage and its association with sociodemographic characteristics, sexual health, healthcare access, psychosocial problems, and substance use in a large multicity sample of community-recruited GBMSM in Nigeria (N = 406). Bivariate and multivariable ordinal logistic regression procedures were used to examine factors associated with GSN apps usage. We found that 52.6% of participants reported recent (≤ 3 months) GSN apps use to meet sexual partners. Factors associated with increased odds of GSN apps usage included: being single, having a university degree or higher, reporting higher recent receptive anal sexual acts, being aware of PrEP, having a primary care provider, and reporting higher levels of identity concealment. HIV-related intervention delivered through GSN apps may help curb the spread of HIV among Nigerian GBMSM.

地理社交网络应用程序 (GSN 应用程序) 被同性恋、双性恋和其他男男性行为者 (GBMSM) 广泛用于结识潜在的性/浪漫伴侣、培养友谊和建立社区。然而，GSN 应用程序的使用与 GBMSM 中艾滋病毒性风险行为的水平升高有关。人们对 GSN 应用程序如何促进 HIV 性风险行为知之甚少，尤其是在非洲的 GBMSM 中。为了填补这一研究空白，本研究旨在描述尼日利亚社区招募的 GBMSM 的大型多城市样本中 GSN 应用程序的使用频率及其与社会人口学特征、性健康、医疗保健可及性、心理社会问题和物质使用的关联(N = 406)。双变量和多变量有序逻辑回归程序用于检查与 GSN 应用程序使用相关的因素。我们发现 52.6% 的参与者报告最近（≤ 3 个月）GSN 应用程序用于会见性伴侣。与 GSN 应用程序使用几率增加相关的因素包括：单身、拥有大学学位或更高学历、报告近期接受肛交的次数较多、了解 PrEP、有初级保健提供者以及报告较高程度的身份隐藏。通过 GSN 应用程序提供的与 HIV 相关的干预措施可能有助于遏制 HIV 在尼日利亚 GBMSM 中的传播。报告最近接受性更高的肛交行为，意识到 PrEP，有初级保健提供者，并报告更高水平的身份隐瞒。通过 GSN 应用程序提供的与 HIV 相关的干预措施可能有助于遏制 HIV 在尼日利亚 GBMSM 中的传播。报告最近接受性更高的肛交行为，意识到 PrEP，有初级保健提供者，并报告更高水平的身份隐瞒。通过 GSN 应用程序提供的与 HIV 相关的干预措施可能有助于遏制 HIV 在尼日利亚 GBMSM 中的传播。
