Abstract：
The purpose of this study was to examine and quantify spatial mobility among HIV-negative young men who have sex with men (YMSM) within and across high prevalence HIV neighborhoods in New York City (NYC). We completed an analysis with global positioning system (GPS) and survey data to quantify spatial mobility for participants enrolled in the P18 Neighborhood Study (analytic n = 211; 83.4%). Spatial mobility was documented with self-reported survey data and objective GPS data, which was uncorrelated. Nearly one-quarter of participants (26.1%) said that they consider the neighborhood in which they currently live to differ from the neighborhood in which they had sex most frequently. In addition, 62.9% of participants\' GPS points were recorded in NYC ZIP Code Tabulation Areas within the highest quartile of HIV prevalence. Future studies of YMSM populations should be conducted to examine how environments beyond the residential neighborhood can influence sexual health, which may guide HIV prevention services.
摘要：
这项研究的目的是检查和量化纽约市（NYC）艾滋病毒高流行社区内和整个地区的与男性发生性关系的艾滋病毒阴性年轻男性（YMSM）的空间流动性。我们完成了全球定位系统（GPS）和调查数据的分析，以量化参加P18邻里研究的参与者的空间移动性（分析n=211；83.4％）。使用自我报告的调查数据和客观的GPS数据记录了空间流动性，这是不相关的。近四分之一的参与者（26.1％）表示，他们认为他们目前居住的社区与他们最常发生性行为的社区不同。此外,62.9％的参与者的GPS点记录在艾滋病毒流行率最高的四分位数内的纽约市邮政编码表格区域中。应该对YMSM人群进行未来的研究，以检查住宅区以外的环境如何影响性健康，这可以指导艾滋病毒预防服务。
