BEYOND RACE--EXPLAINING INEQUALITY MANIFESTED AS OBESITY

描述（改编自研究者摘要）：健康不平等 与种族/族裔、收入和教育有关的歧视继续是 美国人口。不平等的一个重要表现是， 慢性病危险因素流行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， 仍然没有完全理解为什么差距持续存在，而且在某些情况下正在扩大。 本申请建议通过将注意力集中在 超重和体育活动和不活动的模式在美国青年， 他们从青春期过渡到成年期，使用的数据来自 国家青少年健康纵向研究的三个浪潮（补充） 健康）。该申请建议研究超重和活动，因为 超重和活动是两个最大的可改变的风险因素， 心血管疾病和糖尿病。添加健康数据非常适合于此 研究，因为他们来自一个纵向的，基于人口的调查， 包括大量的少数民族样本，并提供深入的SES和背景数据。 主要目标是找出造成男女平等差距的具体因素。 通过研究社会经济， 人口、社区、家庭和个人因素起作用或相互作用， 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， 从青春期到青年期的过渡期的活动/不活动， 拟议的项目将侧重于分析模式和决定因素， 活动/不活动和超重的动态。它还将审查 在青春期早期建立的模式持续到 成年这将包括对初始状态和因素的分析， 在过渡期（即第二波和第三波之间）运行， 影响地位变化，包括审查这些因素 与初始特征相互作用以影响变化。 最后，利用添加健康特殊样本的兄弟姐妹对， 拟议的项目将确定社会经济和背景因素， 解释了兄弟姐妹超重和活动模式的差异。这 这项工作将提供重要的见解，在相对重要的遗传和 超重和活动的环境决定因素。

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.
