项目摘要

DESCRIPTION (provided by applicant): Understanding Disparities in Obesity and Its Comorbidities in the U.S. Obesity/overweight has become a public health crisis in the U.S., and currently affects 2/3 of adults and 1/3 of children. Obesity can serve as a good indicator of unhealthy lifestyles such as unhealthy diet and inadequate physical activity (PA), two key modifiable risk factors for many chronic diseases including Type 2 diabetes (T2D) and hypertension (HBP). National data show large ethnic/SES disparities in obesity, T2D, HBP and healthcare. Obesity is believed as the result of a large number of biological, behavioral, social, environmental and economic factors and the complex interactions between them that promote a positive energy balance. The determinants of these disparities are still poorly understood. Many speculations have been made regarding the major contributors based on a growing body of literature, which has focused largely on individual factors such as SES, body image, and lifestyle factors and in some recent studies regarding selected community characteristics. Our understanding of the relative contribution of these factors, the interplay between them, and the social, economic and environmental context on individual-level behaviors is limited. Our proposed 3-year study is a systematic investigation based on data collected from national surveys, large cohort studies and other sources and aims to understand the causes of ethnic/SES disparities in obesity and its co-morbidities (T2D and HBP) as well as the related health care in the U.S., both adults and children. We will use an interdisciplinary approach to study the determinants at the individual-, family-, and community- level using several sophisticated statistical methods: Aim 1: To study the modifiable determinants of ethnicity/SES disparities in obesity and main co-morbidities. We will study the contributions (in absolute and relative terms) of risk factors at the individual-, family-, and community-level, including psychosocial, behavioral, environmental, economic, and policy factors. Aim 1a: Study the contribution of individual-level (e.g., diet, PA, SES, social support, psychosocial factors), and family-level variables (e.g., SES, participation in food assistance programs, resemblance between parents and their children in diet, PA, and weight status); Aim 1b: Study the contribution of social context factors (e.g., food outlets, fitness facilities, food prices, community characteristics, school PE and recess policies, school food service). Aim 1c: Consider all related factors at multi-levels simultaneously to study their relative contributions. Aim 1d: Using similar approaches study T2D and HBP. Aim 1e: Conduct ecological/ aggregated analysis to study the underlying causes of the disparities at the state and metropolitan statistical area (MSA) levels. Aim 2: To study the influence of primary healthcare on the disparities of obesity and the causes of health care (related to obesity) disparities. Aim 3: To conduct simulation analyses using systems analysis approaches to examine the effects of potential interventions and scenarios for helping eliminate the ethnicity/SES disparities. Findings of this study will help achieve several of the objectives specified in the NIH PAR, and help direct future interventions to eliminate health disparities. PUBLIC HEALTH RELEVANCE: The proposed 3-year study is a systematic investigation based on data from national surveys and other sources to understand the individual-, family-, and community-level causes of ethnic/SES disparities in obesity and its co-morbidities including type 2 diabetes and hypertension as well as the related health care in the U.S. using an interdisciplinary approach.

描述（由申请人提供）：了解美国肥胖及其合并症的差异。肥胖/超重已成为美国的公共卫生危机，目前影响了三分之二的成年人和三分之一的儿童。肥胖可以作为不健康生活方式的良好指标，如不健康的饮食和身体活动不足（PA），这是许多慢性疾病（包括2型糖尿病（T2 D）和高血压（HBP））的两个关键可改变的风险因素。国家数据显示，在肥胖、2型糖尿病、高血压和医疗保健方面存在巨大的种族/社会经济地位差异。肥胖被认为是大量生物，行为，社会，环境和经济因素以及它们之间促进积极能量平衡的复杂相互作用的结果。对这些差异的决定因素仍然知之甚少。许多猜测已经作出了关于主要贡献者的基础上越来越多的文献，其中主要集中在个人因素，如社会经济地位，身体形象，生活方式的因素，并在最近的一些研究中选择的社区特征。我们对这些因素的相对贡献、它们之间的相互作用以及社会、经济和环境背景对个人行为的影响的理解是有限的。我们提出的3年研究是一项系统性研究，基于从全国调查、大型队列研究和其他来源收集的数据，旨在了解肥胖及其合并症（T2 D和HBP）的种族/SES差异的原因，以及美国的相关医疗保健，包括成人和儿童。我们将使用跨学科的方法来研究在个人，家庭和社区水平的决定因素，使用几个复杂的统计方法：目的1：研究种族/SES差异的肥胖和主要的合并症的可修改的决定因素。我们将研究风险因素在个人，家庭和社区层面的贡献（绝对和相对），包括心理，行为，环境，经济和政策因素。目标1a：研究个人层面的贡献（例如，饮食、PA、SES、社会支持、心理社会因素）和家庭水平变量（例如，SES，参与食品援助计划，父母和他们的孩子在饮食，PA和体重状况方面的相似性）;目标1b：研究社会背景因素的贡献（例如，食品店、健身设施、食品价格、社区特色、学校体育和课间休息政策、学校食品服务）。目标1c：同时考虑多个水平的所有相关因素，以研究它们的相对贡献。目的1d：使用类似的方法研究T2 D和HBP。目标1 e：进行生态/综合分析，研究州和大都市统计区（MSA）一级差异的根本原因。目的2：研究初级卫生保健对肥胖差异的影响，以及肥胖相关卫生保健差异的原因。目标三：使用系统分析方法进行模拟分析，以检查潜在干预措施和情景的效果，以帮助消除种族/社会经济地位差异。这项研究的结果将有助于实现NIH PAR中规定的几个目标，并有助于指导未来的干预措施，以消除健康差距。公共卫生相关性：这项拟议的3年研究是一项系统性调查，基于国家调查和其他来源的数据，以了解肥胖及其合并症（包括2型糖尿病和高血压）的种族/SES差异的个人，家庭和社区层面的原因，以及美国使用跨学科方法的相关医疗保健。
