背景：公共住房居民在预防慢性病的健康行为实践中面临着重大的社会、经济和身体障碍。研究表明，与非公共住房居民相比，公共住房居民的肥胖、当前吸烟、残疾和身体活动不足的比例更高。由于这些行为和条件可能受到他们所居住的建筑和社会环境的影响，因此我们进行了一项研究，以测试针对城市公共住房开发中的肥胖问题的环境水平饮食和身体活动干预措施。方法：本研究是公共住房开发的整群随机对照试验，是分析和随机化的单位。总共招募了 10 个公共住房开发项目，随后随机分组接受干预方案或作为比较地点。为期一年的干预措施包括改变开发项目中与饮食和身体活动相关的环境。基线和一年随访调查提供了干预和控制发展中参与者行为和体重变化的数据。结果：干预参与者的饮食和活动行为以及体重从基线到一年随访均显着改变（p < .05），而对照参与者报告任何研究变量没有显着变化。结论：这些数据初步支持了以下观点：针对公共住房开发环境的干预措施可以帮助居民改变不健康行为，并可能减少高风险行为。公共住房居民的慢性病水平。
Background: Public housing residents face significant social, economic, and physical barriers to the practice of health behaviors for prevention of chronic disease. Research shows that public housing residents are more likely to report higher rates of obesity, current smoking, disability, and insufficient physical activity compared to individuals not living in public housing. Because these behaviors and conditions may be shaped by the built and social environments in which they live, we conducted a study to test an environmental level diet and physical activity intervention targeting obesity among urban public housing developments.Methods: This study was a cluster randomized controlled trial of public housing developments, the unit of analysis and randomization. A total of 10 public housing developments were recruited and subsequently randomized to either receive the intervention package or to serve as comparison sites. The year-long intervention included components to change the dietary and physical activity-related environments of the developments. Surveys at baseline and one-year follow-up provided data on changes in behaviors and weight from participants in both intervention and control developments.Results: Intervention participants significantly changed their eating and activity behaviors and body weight from baseline to on-year follow-up (p's < .05) while comparison participants reported no significant changes in any study variable.Conclusions: These data provide initial support for the idea that interventions targeting the environment of public housing developments can assist residents to change unhealthy behaviors and can possibly reduce the high levels of chronic disease among public housing residents.
