项目摘要

Poor dietary and physical activity (PA) behaviors escalate risk for obesity, cancer, and other chronic diseases, and contribute to disparities. Mid-life is a vulnerable life stage when obesity rates peak and chronic diseases emerge. Neighborhood environments provide opportunities, barriers, and cues/triggers to engage in healthy or unhealthy behaviors. Overall, however, research findings on environment-behavior associations are inconsistent and effect sizes are small. This research is limited by sole focus on residential neighborhoods, failure to consider the environment’s role in within-person daily and momentary differences in behaviors, and scarce attention to identifying for whom the environment matters and under what conditions. A new approach is needed that considers the broader environment where people spend time (activity space). Our objective in the proposed study is to address misspecification of environmental exposures ubiquitous in prior research and provide a definitive test of activity-space environment explanations for between-and within-person diet and PA variations during mid-life. The central hypotheses are that activity-space environmental exposures contribute to both between- and within-person variations in dietary and PA behaviors and more strongly influence these behaviors than residential-neighborhood environments alone. Drawing on Temporal Self-Regulation Theory, we also hypothesize activity-space environmental exposures are more consequential for diet and PA when self-regulatory capacity—trait or state factors that affect a person’s ability to make efforts to regulate behavior—is diminished. An in-depth, rigorous study of 510 Latinx, African American, and White adults ages 40-64 is proposed. We will use a rich combination of cutting-edge geographically-explicit ecological momentary assessment (GEMA) methodologies: global positioning system (GPS) location tracking; smartphone-based mini-surveys of diet, PA, and state factors; and accelerometry, as well as three 24-hour dietary recalls, anthropometric measurements, and questionnaires of trait and other factors. Sophisticated routine, daily, and momentary activity-space measures will be derived based on the spatial extent of their movement, but also duration of exposure. Multiple features of the residential and activity-space environments will be measured using GIS including absolute and relative availability of healthful and unhealthful foods, walkability, recreational resource availability (e.g., parks, fitness facilities, greenness), and crime. For the first time, this innovative research will employ a dynamic environmental exposure approach using GEMA to supply evidence on the environment’s role in between- and within-person variations in diet and PA during mid-life, a pivotal time, in a racially/ethnically diverse sample. As such it will contribute to a much-needed shift in how environmental determinants of behaviors are studied, making a lasting impact on the field. Our research is significant because the results can inform new targets for lifestyle and place-based interventions to improve health during mid-life and set the stage for better later-life health.

饮食和体育锻炼不良（PA）行为升级了肥胖，癌症和其他慢性疾病的风险，并有助于差异。中年是肥胖率峰值和慢性疾病的脆弱生命阶段出现。邻里环境提供机会，障碍和提示/触发器，以从事健康或不健康的行为。但是，总的来说，关于环境行为协会的研究结果是不一致和效果大小很小。这项研究受到唯一关注居民社区的限制，未能考虑环境在每日内部和行为的瞬时差异中的作用，以及很少注意确定环境在什么条件下对谁重要。一种新方法需要考虑人们花费时间（活动空间）的更广泛的环境。我们的目标拟议的研究是针对先前研究中无处不在的环境暴露的指定规定，提供有关活动空间环境的确切测试，以解释跨性别饮食和PA 中年的变化。中心假设是活动空间环境暴露有助于饮食和PA行为的人之间和内部差异都更加强烈地影响这些行为仅比居民 - 邻居环境。利用时间自我调节理论，我们还假设活动空间环境暴露对饮食和PA的影响更大自我调节能力 - 影响一个人努力调节能力的特质或状态因素行为 - 减少了。对510名拉丁裔，非裔美国人和白人成年人的深入，严格的研究提出了40-64。我们将使用尖端的地理学生态瞬间结合评估（GEMA）方法：全球定位系统（GPS）位置跟踪；基于智能手机饮食，宾夕法尼亚州和状态因素的迷你服务；和加速度计，以及三个24小时饮食召回，人体测量值和特征和其他因素的问卷。每日精致的例行程序，瞬时活动空间措施将根据其运动的空间范围得出暴露时间。将测量居民和活动空间环境的多个功能使用GIS，包括健康和不健康食品的绝对和相对可用性，步行，娱乐活动资源可用性（例如公园，健身设施，绿色）和犯罪。这是第一次创新研究将采用GEMA采用动态的环境暴露方法来提供证据环境在中期的饮食和饮食中和人际关系之间的作用，一个关键时期种族/种族多样的样本。因此，它将导致急需的环境转变行为的决定因素是研究的，对该领域产生了持久的影响。我们的研究很重要，因为结果可以为新目标提供生活方式和基于地点的干预措施，以改善中年的健康并为更好的后期健康奠定了基础。
