Respondent-driven sampling (RDS) relies on productive peer recruitment to capture hidden populations. Domestic studies have identified characteristics of productive recruitment among RDS samples of men who have sex with men and persons who use drugs, but not of women who exchange sex, a group vulnerable to HIV infection. We examined sociodemographic-, behavioral-, exchange-sex-, and protocol-related factors associated with recruitment among seeds (n = 25) and peers (n = 297) in the 2016 New York City National HIV Behavioral Surveillance Study cycle focused on women who exchange sex. Recruiter productivity was significantly associated with not having been recently incarcerated, lower rate of HIV testing, and larger exchange sex networks among seeds, and with HIV-prevention services usage among peers. We describe challenges and lessons learned from implementing RDS in this population. Our study identifies seed characteristics and protocol improvements researchers can utilize when implementing future RDS studies among women who exchange sex.
应答驱动抽样（RDS）依靠有效的同伴招募来获取隐藏人群。国内研究已确定了男男性行为者和吸毒者的RDS样本中有成效招募的特征，但尚未确定易感染艾滋病毒的性交易女性群体的此类特征。在2016年纽约市全国艾滋病毒行为监测研究周期中，我们针对性交易女性群体，研究了与种子人群（n = 25）和同伴人群（n = 297）招募相关的社会人口学、行为、性交易和方案相关因素。招募者的成效与种子人群中近期未被监禁、艾滋病毒检测率较低以及性交易网络较大显著相关，与同伴人群中使用艾滋病毒预防服务也显著相关。我们描述了在这一人群中实施RDS所面临的挑战和经验教训。我们的研究确定了种子人群特征和方案改进措施，研究人员在未来针对性交易女性开展RDS研究时可以加以利用。
