 DESCRIPTION (provided by applicant): This R21 is directly responding to the PAR-12-197 on Improving Diet and Physical Activity Assessment. Research suggests that the environment influences lifestyle behaviors and contributes to racial and socioeconomic inequities in health, but overall, results are inconsistent and effect sizes are small. One potential explanation is measurement error in environmental exposures. Despite that many individuals spend considerable time outside their immediate neighborhood, most research has solely measured environmental exposures in a respondent's residential space and failed to take into account daily mobility. The objective of the proposed R21 is to examine the joint spatial and temporal stability of activity spaces (AS) derived from GPS data in a racially/ethnically and socioeconomically diverse sample of adults. Specific aims are: 1. Determine the optimal number and combination of days of GPS tracking needed to represent an individual's AS by testing the temporal stability within a person across days, types of days (e.g., weekend, weekdays), and between weeks. 2. Determine the sufficiency of using only one time period for GPS tracking by examining the temporal stability of an individual's AS within and between seasons. 3. As an exploratory aim, we will compare participant AS as derived from GPS tracking with those derived from questionnaires, with comparisons based on AS overlap, size, and environmental attributes. To achieve these aims, we will conduct GPS tracking with a socio-economically diverse sample of 144 African American, Mexican American, and white adults in Chicago for 30 days at baseline, with a second wave on a sub-sample six months later. We will measure physical activity using accelerometry and dietary intakes using multiple 24-hour dietary recalls. GIS will be used to construct measures of AS (e.g., route network buffer, kernel density estimation) and environmental attributes. This study will address key barriers to the advancement of a next generation of studies on the environment and lifestyle behaviors utilizing AS. Findings will supply essential information for a planned R01 on influences of AS environment attributes on lifestyle behaviors in a population-based multiethnic sample of adults.

 描述（由适用提供）：此R21直接负责PAR-12-197，以改善饮食和体育锻炼评估。研究表明，环境会影响生活方式的行为，并导致健康和社会经济不平等，但总的来说，结果是不一致的，效果大小很小。一种潜在的解释是环境暴露的测量误差。尽管许多人在附近的附近度过了相当长的时间，但大多数研究仅测量了负责任的居住空间中的环境暴露，并且未能考虑到每日流动性。所提出的R21的目的是检查在大致/种族和社会经济多样化的成年人样本中，来自GPS数据的活动空间的关节空间和临时稳定性（AS）。具体目的是：1。确定代表个人所需的GPS跟踪天数的最佳数量和组合，通过测试一个人，几天，几天（例如，周末，周）和几周之间的人的临时稳定性。 2.通过检查个人在季节内和季节之间的临时稳定性，确定仅使用一段时间进行GPS跟踪的安全性。 3。作为探索目的，我们将比较从GPS跟踪中衍生的参与与来自问卷调查的参与，并基于AS重叠，大小和环境属性的比较。为了实现这些目标，我们将通过144名非裔美国人，墨西哥裔美国人和芝加哥的白人成年人在基线上进行30天的社会经济多样性样本进行GPS跟踪，第二波在六个月后进行了第二波浪潮。我们将使用多个加速度测量法和饮食摄入量来测量体育活动。 24小时的饮食召回。 GIS将用于构建AS的度量（例如，路由网络缓冲区，内核密度估计）和环境属性。这项研究将介绍有关利用AS的下一代研究和生活方式行为的下一代研究的关键障碍。调查结果将为计划中的R01提供基本信息，以了解基于人群的成年人多民族样本中对环境行为的影响。
