Finding and accessing members of youth subpopulations, such as young men who have sex with men (YMSM) of color or young females of color, for behavioral or disease surveillance or study recruitment, pose particular challenges. Venue-based sampling strategies--which hinge on where individuals congregate or "hang out" rather than where they live--appear to be effective alternatives. Methods used to identify venues focus on engaging members of social networks to learn where targeted populations congregate. However, it is not always clear if and how these methods differ according to gender, whether the youth accessed at a venue are actually from neighborhoods in which the venues are found, and whether the location of venues relative to neighborhoods of residence is different for young men and young women. This study illustrates the gender differences in venue type and venue location where eligible youth study participants from high-risk neighborhoods could be accessed for HIV research across 15 research sites (sites). The findings indicate that the study's method led to identifying venues where one quarter or more of the youth were eligible study participants and from the high-risk neighborhoods. Sites targeting young women of color had a higher proportion of eligible study participants who were also from the high-risk neighborhoods than sites targeting YMSM. Clubs were most commonly identified by sites targeting YMSM as recruitment venues, whereas neighborhood-based service or commercial centers were more common venues for young women of color. This study reveals how venue-based recruitment strategies can be tailored and resources maximized by understanding the key differences in the types of venues preferred by males and females and by recognizing that female-preferred venues are more likely to be closer to home.
对于行为监测或疾病监测以及研究招募而言,寻找并接触青年亚人群体的成员,比如有色人种男男性行为者(YMSM)或有色人种青年女性,存在特殊挑战。基于场所的抽样策略——其取决于个体聚集或“闲逛”的地点而非他们居住的地方——似乎是有效的替代方法。用于识别场所的方法侧重于让社交网络成员参与进来,以了解目标人群聚集的地点。然而,这些方法是否以及如何因性别而异、在某个场所接触到的青年是否实际上来自该场所所在的社区,以及青年男性和青年女性的场所位置相对于居住社区是否不同,并不总是很清楚。本研究说明了在15个研究地点进行艾滋病毒研究时,在场所类型和场所位置方面的性别差异,通过这些差异可以接触到来自高危社区的符合条件的青年研究参与者。研究结果表明,该研究的方法能够识别出四分之一或更多青年是符合条件的研究参与者且来自高危社区的场所。针对有色人种青年女性的地点中,来自高危社区的符合条件的研究参与者比例高于针对YMSM的地点。针对YMSM的地点最常将俱乐部识别为招募场所,而基于社区的服务或商业中心是有色人种青年女性更常见的场所。这项研究揭示了如何通过了解男性和女性偏好的场所类型的关键差异,并认识到女性偏好的场所更可能离家更近,来调整基于场所的招募策略并最大限度地利用资源。
