While migration has been shown to be a risk factor for HIV, variation in HIV prevalence by subgroups of migrants needs further exploration. This paper documents the HIV prevalence and key characteristics among male foreign migrants in Cape Town, South Africa and the effectiveness of respondent-driven sampling (RDS) to recruit this population. Participants in this cross-sectional study completed a behavioral risk-factor questionnaire and provided a dried blood sample for HIV analysis. Overall HIV prevalence was estimated to be 8.7 % (CI 5.4-11.8) but varied dramatically by country of origin. After adjusting for country of origin, HIV sero-positivity was positively associated with older age (p = 0.001), completing high school (p = 0.025), not having enough money for food (p = 0.036), alcohol use (p = 0.049), and engaging in transactional sex (p = 0.022). RDS was successful in recruiting foreign migrant men. A better understanding of the timing of HIV acquisition is needed to design targeted interventions for migrant men.
虽然移民已被证明是感染艾滋病毒的一个风险因素，但不同移民亚群体的艾滋病毒流行率差异仍需进一步探究。本文记录了南非开普敦男性外国移民中的艾滋病毒流行率及关键特征，以及应答驱动抽样（RDS）在招募该人群方面的有效性。这项横断面研究的参与者完成了一份行为危险因素问卷，并提供了一份用于艾滋病毒分析的干血样。总体艾滋病毒流行率估计为8.7%（置信区间5.4 - 11.8），但因原籍国不同而有很大差异。在对原籍国进行调整后，艾滋病毒血清阳性与年龄较大（p = 0.001）、完成高中学业（p = 0.025）、没有足够的钱购买食物（p = 0.036）、饮酒（p = 0.049）以及从事交易性行为（p = 0.022）呈正相关。应答驱动抽样成功招募到了外国移民男性。为移民男性设计有针对性的干预措施需要更好地了解艾滋病毒感染的时间。
