Men who have sex with men (MSM), especially MSM of color, are disproportionately impacted by HIV/AIDS compared to heterosexuals and Caucasians. Nonetheless, fewer sexual and ethnic minorities participate in prevention interventions for people with HIV. We consider recruitment for Positive Connections, a randomized controlled trial comparing unsafe sex prevention interventions primarily for HIV-positive (HIV+) MSM in six US epicenters. One community-based organization (CBO) in each city recruited adult MSM, particularly men of color and HIV+. Recruitment methods included on-line and print advertising, outreach events, health professionals, and social networks. Data on demographics, HIV status, and recruitment method were collected at registration. We tested for differences in registration proportions and attendance rates by recruitment strategy, stratified on race/ethnicity and serostatus. Of the 1,119 registrants, 889 attended the intervention. The sample comprised 41% African American, 18% Latino/Hispanic, and 77% HIV+. Friend referral was reported by the greatest proportion of registrants, particularly among African American (33%) and HIV+ men (25%). Print advertising yielded the largest proportions of non-Hispanic white (27%) and HIV-negative registrants (25%). Registrants recruited on-line were the least likely to attend (45% versus 69% average); this effect was strongest among Latino/Hispanic (27% attendance) and non-Hispanic white men (36%). Retention during the follow-up period did not differ by serostatus, race/ethnicity, or recruitment method. Differential attendance and retention according to recruitment strategy, serostatus, and racial/ethnic group can inform planning for intervention sample size goals.
男男性行为者(MSM),尤其是有色人种的 MSM,与异性恋者和白种人相比,受艾滋病毒/艾滋病的影响不成比例。尽管如此,参与艾滋病毒感染者预防干预措施的性少数群体和少数族裔仍然较少。我们考虑招募参加“积极联系”(Positive Connections),这是一项在美国六个艾滋病流行中心比较针对艾滋病毒阳性(HIV+)MSM 的不安全性行为预防干预措施的随机对照试验。每个城市的一个社区组织(CBO)招募成年 MSM,特别是有色人种和 HIV+男性。招募方法包括在线和印刷广告、外展活动、卫生专业人员和社交网络。在注册时收集人口统计学、艾滋病毒状况和招募方法的数据。我们根据种族/族裔和血清状况分层,测试了不同招募策略的注册比例和出席率差异。在 1119 名注册者中,889 人参加了干预。该样本包括 41%的非裔美国人、18%的拉丁裔/西班牙裔和 77%的 HIV+。朋友推荐是报告注册者中最大比例的招募方式,尤其是在非裔美国人和 HIV+男性中(分别为 33%和 25%)。印刷广告产生了最大比例的非西班牙裔白人(27%)和 HIV 阴性注册者(25%)。在线招募的注册者最不可能出席(45%对平均 69%);这种影响在拉丁裔/西班牙裔(27%的出勤率)和非西班牙裔白种人男性(36%)中最强。在随访期间,保留率不因血清状态、种族/族裔或招募方法而异。根据招募策略、血清状态和种族/族裔群体的不同参与和保留情况,可以为干预样本量目标的规划提供信息。
