Male sex workers (MSW) in the Dominican Republic (DR) have multiple sexual partners, including personal and client-relationships, and are disproportionately affected by human immunodeficiency virus (HIV). We examined the prevalence of condomless anal and/or vaginal intercourse (CI) among MSW in the DR as a function of social network factors. Self-report surveys and social network interviews were administered to MSW recruited through venue-based sampling (N = 220). A generalized linear model was used to complete a Poisson Regression model and identify variables significantly associated with the outcome of interest. CI was more common with female (28.3%) than with male partners (4.9%). Factors associated with CI with the last female partner included older age of MSW, CI with the last male partner, having a stable female partner (a consistent or main partner), and having ≥1 family member in the participants' social network. Partner and social network characteristics associated with CI among MSW suggest the utility of dyadic and network interventions to reduce HIV risk.
多米尼加共和国的男性性工作者（MSW）有多个性伴侣，包括个人和客户关系，并且不成比例地受到人类免疫缺陷病毒（HIV）的影响。我们研究了多米尼加共和国 MSW 中无保护肛交和/或阴道交（CI）的流行率，作为社会网络因素的函数。通过基于场所的抽样（N=220）招募 MSW 并进行自我报告调查和社会网络访谈。使用广义线性模型完成泊松回归模型，并确定与感兴趣的结果显著相关的变量。与女性（28.3%）相比，MSW 与男性伴侣（4.9%）发生 CI 的情况更为常见。与最后一名女性伴侣发生 CI 的相关因素包括 MSW 年龄较大、与最后一名男性伴侣发生 CI、有稳定的女性伴侣（稳定或主要伴侣），以及参与者社交网络中至少有 1 名家庭成员。与 MSW 中的 CI 相关的伴侣和社会网络特征表明，双伴侣和网络干预措施对于降低 HIV 风险具有实用性。
