在过去的10年里，互联网已经成为男男性行为者(MSM)结交性伴侣的场所。由于MSM中线上性行为的增加，基于互联网的人类免疫缺陷病毒(HIV)预防干预措施引起了人们的兴趣。然而，到目前为止，很少有在线研究表明在纵向在线研究中能够留住研究参与者，特别是有色人种的MSM。目前的分析检查了为期3个月的MSM在线前瞻性研究的数据，以确定种族和激励水平与两个保留结果的关联：(1)同意参与后续调查并提供电子邮件地址；(2)在后续时间点链接到后续调查。使用互联网的MSM是通过MySpace.com上的横幅广告招募的。18至35岁的白人、黑人和西班牙裔参与者被随机分配到四个激励水平(0美元、5美元、10美元和20美元)的在线跟踪调查中。多变量Logistic回归模型被用来估计控制其他独立感兴趣因素的两个结果指标的几率。在符合条件的参与者中，92%(2405/2607)的人同意参加后续调查，并提供了电子邮件地址。与白人男性相比，拉美裔男性同意参与后续调查的几率降低(调整后的优势比[OR]=0.66，95%可信区间[CI]0.47-0.92)。报告在过去12个月中与男性性伴侣发生无保护肛交的男性增加了同意参与后续调查的几率(调整后的OR=1.42，95%CI为1.05~1.93)。在提供电子邮件地址的参与者中，22%(539/2405)在3个月的跟踪时间点与跟踪调查有关。黑人男性进入后续调查的几率大约是白人男性的一半(调整后的OR=0.47，95%CI为0.35-0.63)。给予奖励的参与者进入后续调查的几率增加(调整后的OR=1.29，95%CI为1.02-1.62)。参与者提供的用于在线财务管理的电子邮件地址和每天检查的电子邮件帐户与链接到后续调查的几率增加相关(调整后的OR=1.97，95%CI 1.54~2.52；调整后的OR=1.51，95%CI 1.22~1.87)。这项分析确定了在一项关于MSM的在线前瞻性研究中预测保留的因素。与白人研究参与者相比，西班牙裔和黑人研究参与者被保留在研究中的可能性较小。由于这些男性在美国男男性接触者中承担着最大的艾滋病毒发病率负担，因此开发新的研究方法以增加这些群体在在线研究研究中的留存率至关重要。
In the past 10 years, the Internet has emerged as a venue for men who have sex with men (MSM) to meet sex partners. Because online sex seeking has increased among MSM, Internet-based human immunodeficiency virus (HIV) prevention interventions are of interest. However, few online studies to date have demonstrated an ability to retain study participants, specifically MSM of color, in longitudinal online studies. The current analysis examines data from a 3-month online prospective study of MSM to determine the association of race and incentive level with two retention outcomes: (1) agreeing to participate in a follow-up survey and providing an email address and (2) linking into the follow-up survey at the follow-up time point. Internet-using MSM were recruited through banner advertisements on MySpace.com. White, black, and Hispanic participants from 18 to 35 years of age were randomized to an offer of enrollment in an online follow-up survey at four levels of incentive (US $0, US $5, US $10, and US $20). Multivariable logistic regression models were used to estimate the odds of the two outcome measures of interest controlling for additional independent factors of interest. Of eligible participants, 92% (2405/2607) agreed to participate in the follow-up survey and provided an email address. Hispanic men had decreased odds (adjusted odds ratio [OR] = 0.66, 95% confidence interval [CI] 0.47-0.92) of agreeing to participate in the follow-up survey compared with white men. Men reporting unprotected anal intercourse with a male sex partner in the past 12 months had increased odds of agreeing to participate in the follow-up survey (adjusted OR = 1.42, 95% CI 1.05-1.93). Of the participants who provided an email address, 22% (539/2405) linked into the follow-up survey at the 3-month follow-up time point. The odds of linking into the follow-up survey for black men were approximately half the odds for white men (adjusted OR = 0.47, 95% CI 0.35-0.63). Participants who were offered an incentive had increased odds of linking into the follow-up survey (adjusted OR = 1.29, 95% CI 1.02-1.62). Email addresses provided by participants that were used for online financial management and email accounts that were checked daily were associated with increased odds of linking into the follow-up survey (adjusted OR = 1.97, 95% CI 1.54-2.52; adjusted OR = 1.51, 95% CI 1.22-1.87, respectively). This analysis identified factors that predicted retention in an online, prospective study of MSM. Hispanic and black study participants were less likely to be retained in the study compared with white study participants. Because these men bear the greatest burden of HIV incidence among MSM in the United States, it is critical that new research methods be developed to increase retention of these groups in online research studies.
