DESCRIPTION (provided by applicant): In a prospective longitudinal study, it is hypothesized that the built environment's walkability will impact the social environment's collective efficacy, and that these environmental variables together will influence physical activity. Controlling for diet, physical activity is hypothesized to predict adiposity, inflammation, and insulin resistance; and these in turn will predict progression in metabolic syndrome indicators. While these relationships have been tested separately, this application proposes an integrated and interdisciplinary test of the relationship among these variables. Hispanic immigrants are selected for this study because Hispanics have disproportionately high rates of diabetes. Moreover, for very recent immigrants, weight increases rapidly as a function of time in the US. The study proposes to explore trajectories of cultural change - and their impact on diet and physical activity - as a mechanism by which 'time in the US' may bring about its deleterious health outcome for this population. A sample is proposed that is uniquely suited to investigate this phenomenon in Hispanics, as well as the impact of the built environment on physical activity and health outcomes: Cuban immigrants within 90 days of arrival to the US. This sample addresses in part the self- selection bias that characterizes most built environment studies, because, when these individuals arrive in Miami-Dade County, they typically move to a neighborhood not of their choosing. Therefore, an ideal natural experiment occurs in which a naive sample in relation to non-walkable environments is distributed across a variety of walkability conditions. Participants will be 390, 30-45 year-old recent immigrants who do not meet criteria for metabolic syndrome. Built environment's walkability will be assessed through self-reports, and objectively using the .25 mile radius surrounding the participant's residence. Participants will be assessed on self-reported measures of collective efficacy, physical activity, diet, and biculturation, and objective measures of physical activity, adiposity, inflammation, insulin resistance, and metabolic syndrome indicators. Variables in the primary analyses will be continuously distributed. Growth curves will be estimated using growth curve methodology in a structural equations framework using Mplus 3.

描述（由申请人提供）：在一项前瞻性纵向研究中，假设建筑环境的步行性将影响社会环境的集体效力，并且这些环境变量共同影响体育活动。控制饮食，假设体育活动可以预测肥胖，炎症和胰岛素抵抗。这些反过来将预测代谢综合征指标的进展。尽管这些关系已分别测试，但该应用程序提出了对这些变量之间关系的综合和跨学科测试。这项研究之所以选择西班牙裔移民，是因为西班牙裔人的糖尿病发生率高。此外，对于最近的移民，随着时间的时间函数，体重迅速增加。该研究建议探索文化变革的轨迹及其对饮食和体育锻炼的影响 - 作为一种机制，“美国时间”可能会给该人群带来有害的健康结果。提出了一个样本，非常适合研究西班牙裔现象，以及建筑环境对体育活动和健康结果的影响：到达美国后的90天内，古巴移民。该示例部分介绍了大多数建筑环境研究的自我选择偏见，因为当这些人到达迈阿密戴德县时，他们通常会搬到不选择的社区。因此，发生了一个理想的自然实验，其中在各种步行性条件下分布了与不可行动环境相关的幼稚样本。参与者将是390、30-45岁的最近移民，他们不符合代谢综合征标准。建筑环境的步行性将通过自我报告进行评估，并使用参与者住所周围的.25英里半径客观地进行评估。参与者将根据自我报告的集体疗效，体育锻炼，饮食和双文化的措施进行评估，以及对体育活动，肥胖，炎症，胰岛素抵抗和代谢综合征指标的客观度量的评估。主要分析中的变量将连续分布。将使用MPLU 3中的结构方程框架中使用生长曲线方法来估计生长曲线。
