描述(改编自调查者摘要)：健康中的不平等 与种族/族裔、收入和教育有关的问题继续成为 美国人口。不平等的一个重要表现是实质性的 慢性病风险因素患病率的种族和民族差异， 发病率和死亡率。尽管对这种差异进行了广泛的研究，但它 人们仍然不完全理解为什么差距持续存在，在某些情况下差距还在扩大。 此应用程序建议通过关注以下内容来研究此问题 美国年轻人的超重和体力活动和不活动的模式 他们从青春期过渡到成年，使用了来自 全国青少年健康纵向研究的三次浪潮(新增 健康)。该应用程序建议研究超重和运动，因为 超重和运动是两个最大的可修改的风险因素 心血管疾病和糖尿病。添加健康数据非常适合于此 因为他们来自一项纵向的、基于人口的调查 包括大量少数群体样本，并提供深入的SES和背景数据。 主要目标是找出造成这一差距的具体因素。 少数族裔人口的健康结果，通过观察社会经济， 人口、社区、家庭和个人因素作用或相互作用影响 超重和活动模式。 在充分记录了超重和肥胖的流行模式之后 从青春期过渡到青壮年的活动/不活动， 拟议项目将侧重于对模式和决定因素的分析。 运动/不运动和超重的动态变化。它还将检查 在青春期早期形成的模式持续到什么程度 成人期。这将包括对初始状态和以下因素的分析 在过渡期间(即在第二波和第三波之间)运行以 影响地位的变化，包括审查这些因素是如何 与初始特征相互作用以影响变化。 最后，利用兄弟姐妹对的Add Health特殊样本， 拟议的项目将确定社会经济和背景因素， 解释了兄弟姐妹在超重和活动模式上的差异。这 这项工作将为我们提供关于基因和 超重和运动的环境决定因素。

DESCRIPTION (adapted from investigator's abstract): Inequality in health related to race/ethnicity, income and education continues to characterize the U.S. population. One important manifestation of inequality is the substantial racial and ethnic differences in prevalence of chronic disease risk factors, morbidity and mortality. Despite extensive research on such differentials, it still is not fully understood why gaps persist, and are in some cases widening. This application proposes to study this issue by focusing attention on overweight and patterns of physical activity and inactivity in U.S. youths as they make the transition from adolescence to adulthood, using data from the three waves of the National Longitudinal Study of Adolescent Health (Add Health). The application proposes to study overweight and activity because overweight and activity are two of the top modifiable risk factors for cardiovascular disease and diabetes. Add Health data are well suited for this research because they come from a longitudinal, population-based survey that includes large minority samples and provides in-depth SES and contextual data. The main goal is to identify specific factors that account for the disparity of health outcomes in minority populations by looking at how socioeconomic, demographic, community, family and individual factors act or interact to affect overweight and activity patterns. After fully documenting patterns of prevalence of overweight and activity/inactivity over the transition from adolescence to young adulthood, the proposed project will focus on an analysis of the patterns and determinants of the dynamics of activity/inactivity and overweight. It also will examine the extent to which patterns established in early adolescence persist into adulthood. This will include an analysis of initial status and factors that operate during the transition period (i.e. between waves two and three) to influence change in status, including an examination of how such factors interact with initial characteristics to affect change. Finally, taking advantage of the Add Health special sample of sibling pairs, the proposed project will identify socioeconomic and contextual factors that account for sibling differences in overweight and patterns of activity. This work will provide important insights in the relative importance of genetic and environmental determinants of overweight and activity.
