This study examined patterns of connectedness among 774 sexually-active gay, bisexual, and other men who have sex with men (GBM), aged ≥ 16 years, recruited using respondent-driven sampling in Metro Vancouver. Latent class analysis examined patterns of connectedness including: attendance at gay venues/events (i.e., bars/clubs, community groups, pride parades), social time spent with GBM, use of online social and sex seeking apps/websites, and consumption of gay media. Multinomial regression identified correlates of class membership. A three-class LCA solution was specified: Class 1 "Socialites" (38.8%) were highly connected across all indicators. Class 2 "Traditionalists" (25.7%) were moderately connected, with little app/website-use. Class 3 "Techies" (35.4%) had high online connectedness and relatively lower in-person connectedness. In multivariable modelling, Socialites had higher collectivism than Traditionalists, who had higher collectivism than Techies. Socialites also had higher annual incomes than other classes. Techies were more likely than Traditionalists to report recent serodiscordant or unknown condomless anal sex and HIV risk management practices (e.g., ask their partner's HIV status, get tested for HIV). Traditionalists on the other hand were less likely to practice HIV risk management and had lower HIV/AIDS stigma scores than Socialites. Further, Traditionalists were older, more likely to be partnered, and reported fewer male sex partners than men in other groups. These findings highlight how patterns of connectedness relate to GBM's risk management.
本研究调查了 774 名年龄在 16 岁及以上、活跃于性活跃的男同性恋、双性恋和其他与男性发生性关系（GBM）的人群的联系模式，这些人是在温哥华地铁区通过回应驱动抽样招募的。潜在类别分析考察了包括以下方面的联系模式：参加同性恋场所/活动（即酒吧/俱乐部、社区团体、骄傲游行）、与 GBM 共度的社交时间、使用在线社交和性寻求应用程序/网站，以及消费同性恋媒体。多项回归确定了类别的相关因素。指定了一个三类别 LCA 解决方案：类别 1“社交达人”（38.8%）在所有指标上都高度相关。类别 2“传统主义者”（25.7%）中度相关，很少使用应用程序/网站。类别 3“技术达人”（35.4%）在线联系紧密，而面对面联系相对较少。在多变量建模中，“社交达人”比“传统主义者”更具有集体主义倾向，而“传统主义者”又比“技术达人”更具有集体主义倾向。“社交达人”的年收入也高于其他群体。“技术达人”比“传统主义者”更有可能报告最近的血清不一致或未知的无保护肛交和艾滋病毒风险管理做法（例如，询问伴侣的艾滋病毒状况，接受艾滋病毒检测）。另一方面，“传统主义者”不太可能进行艾滋病毒风险管理，并且艾滋病毒/艾滋病耻辱感评分低于“社交达人”。此外，“传统主义者”年龄较大，更有可能有伴侣，而且报告的男性性伴侣比其他群体的男性性伴侣少。这些发现强调了联系模式如何与 GBM 的风险管理相关。
