Substantial literature demonstrates the influence of the neighborhood environment on health behaviors and outcomes. But limited research examines on how gay and bisexual men experience and exist in various geographic and virtual spaces and how this relates to their sexual behavior. New York City Men 2 Men (NYCM2M) was a cross-sectional study designed to identify neighborhood-level characteristics within the urban environment that influence sexual risk behaviors, substance use, and depression among men who have sex with men (MSM) living in NYC. The sample was recruited using a modified venue-based time-space sampling methodology and through select websites and mobile applications. Whether key neighborhoods of human activity, where a participant resided (termed home), socialized (termed social), or had sex most often (termed sex), were the same or different was evaluated. "Congruence" (or the sameness) of home, social, and most often sex neighborhood was reported by 17 % of men, while 30 % reported that none of their neighborhoods were the same. The largest group of men (39 %) reported that their home and sex neighborhoods were the same but their social neighborhood was different while 10 % reported that their home neighborhood was different than their social and sex neighborhood; 5 % men reported same home and social neighborhoods with a different sex neighborhood. Complete neighborhood incongruence was highest among men who were Black and/or Latino, had lower education and personal income levels, and had greater financial insecurity. In adjusted analysis, serodiscordant condomless anal intercourse and condomless anal intercourse with partners from the Internet or mobile applications were significantly associated with having the same social and sex (but not home) neighborhoods. Understanding the complexity of how different spaces and places relate to the health and sexual behavior of MSM is essential for focusing interventions to best reach various populations of interest.
大量文献表明邻里环境对健康行为及结果有影响。但仅有有限的研究考察了男同性恋者和双性恋男性在不同地理和虚拟空间中的经历与生存状况，以及这与他们性行为的关系。纽约市男性对男性（NYCM2M）是一项横断面研究，旨在确定城市环境中影响居住在纽约市的男男性行为者（MSM）性风险行为、物质使用和抑郁的邻里层面特征。样本通过改良的基于场所的时空抽样方法以及特定网站和移动应用程序招募。评估参与者居住（称为家庭）、社交（称为社交）或最常发生性行为（称为性）的关键人类活动邻里是否相同或不同。17%的男性报告家庭、社交和最常发生性行为的邻里“一致”（即相同），而30%的男性报告他们的邻里都不相同。最大比例的男性（39%）报告他们的家庭和性邻里相同，但社交邻里不同，而10%的男性报告他们的家庭邻里与社交和性邻里不同；5%的男性报告家庭和社交邻里相同但性邻里不同。完全邻里不一致在黑人及/或拉丁裔、教育程度和个人收入水平较低且经济不安全感较高的男性中最为常见。在调整分析中，血清学不一致的无保护肛交以及与来自互联网或移动应用程序的伴侣进行的无保护肛交与社交和性（但不是家庭）邻里相同显著相关。了解不同空间和场所与男男性行为者健康和性行为之间关系的复杂性，对于集中干预以最佳地覆盖各类目标人群至关重要。
