在拉丁美洲，对高危人群的艾滋病毒/性传播感染监测需要便利取样的替代方法。我们比较了CS，时间空间采样（TSS），和应答者驱动采样（RDS）的男性与男性发生性关系（MSM）和变性妇女（TW）在利马，秘鲁的招聘。在2011年6月至8月的60天期间，我们招募了MSM/TW进行流行病学监测，使用CS，TSS和RDS。通过CS招募了748名参与者，通过TSS招募了233名参与者，通过RDS招募了127名参与者。TSS样本包括最大比例的TW（30.7%）和最低比例的受试者谁曾参加过艾滋病毒/性传播感染研究（14.9%）。根据参与者自我报告的先前艾滋病毒诊断，TSS新兵（17.9%）中新诊断的艾滋病毒感染率最高，RDS（12.6%）和CS（10.2%）。技术支助服务查明了各种各样的男男性行为者/图瓦卢妇女，这些人的艾滋病毒/性传播感染率较高，而其他方法无法获得这些资料。
Alternatives to convenience sampling (CS) are needed for HIV/STI surveillance of most-at-risk populations in Latin America. We compared CS, time space sampling (TSS), and respondent driven sampling (RDS) for recruitment of men who have sex with men (MSM) and transgender women (TW) in Lima, Peru. During concurrent 60-day periods from June–August, 2011, we recruited MSM/TW for epidemiologic surveillance using CS, TSS, and RDS. A total of 748 participants were recruited through CS, 233 through TSS, and 127 through RDS. The TSS sample included the largest proportion of TW (30.7 %) and the lowest percentage of subjects who had previously participated in HIV/STI research (14.9 %). The prevalence of newly diagnosed HIV infection, according to participants’ self-reported previous HIV diagnosis, was highest among TSS recruits (17.9 %) compared with RDS (12.6 %) and CS (10.2 %). TSS identified diverse populations of MSM/TW with higher prevalences of HIV/STIs not accessed by other methods.
