Ethnic Trajectories of Aging

描述（由申请人提供）：老年健康轨迹：种族差异老龄化研究越来越关注于检查老龄化与决定身体健康状况的社会因素之间的交叉点。大部分研究都是基于横截面数据。此外，现有的纵向分析主要关注两个时间点之间的转换。这个应用程序分析了健康状况的轨迹，包括白人、非裔美国人和墨西哥裔美国老年人的多重转变。它有三个具体目标。首先，我将研究健康状况的轨迹，以自我评估的健康，残疾水平和种族群体的疾病负担来衡量。其次，我将探讨出生身份在墨西哥裔美国人随着年龄增长的健康轨迹中的作用。将探讨外国出生、在美国生活的时间、移民后的时间和移民时的年龄的影响。最后，我将考虑早期生活的社会经济暴露如何与出生状况相交，从而部分决定了墨西哥裔拉丁美洲人晚年的健康轨迹。为了评估所提出的研究问题，将使用层次线性模型。特别是，按种族身份划分的老年人健康轨迹的变化将用生长曲线表示。用于这些建议的分析的数据将有两个来源。健康与退休研究（HRS）是一项正在进行的，具有全国代表性的公众使用小组研究，抽样年龄在51岁及以上的个人。此外，西班牙裔老年人流行病学研究的既定人口（H-EPESE）将用于验证HRS的发现，因为它的墨西哥裔美国人样本很大。PI: Qui¿ones, Ana R.这项研究与公共卫生的相关性：了解残疾和老年人口下降的趋势对卫生政策制定者至关重要。特别是，确定某些群体的健康状况较其他群体差的老龄化人口所构成的挑战，是一项必要的社会规划工具。这项研究建议检查老年白人、非裔美国人和墨西哥裔美国人的健康趋势，以确定这种衰老的差异模式是否在起作用。

DESCRIPTION (provided by applicant): Trajectories of health in old age: ethnic differences Aging research has been increasingly focused on examining the intersections between aging and social factors involved in determining physical health status. Much of the research is based on cross-sectional data. Further, existing longitiduinal analyses are mostly concerned with transitions between two points in time. This application analyzes trajectories of health status, consisiting of multiple tranisitions among White, African-American and Mexican-origin older Americans. It has three specific aims. First, I will examine trajectories of health status as measured by self-rated health, disability levels, and disease burden by ethnic group. Second, I will explore the role of nativity status on the trajectories of health for Mexican-Americans as they age. The effect of foreign-born, time spent in the U.S., time since migration and age at migration will be explored. Lastly, I will consider how early life socioeconomic exposures intersect with nativity status to partly determine trajectories of health later in life for Mexican-origin Latinos. To evaluate the research questions posed, hierarchical linear models will be used. In particular, changes in health trajectories within an older person by ethnic identity will be represented by growth curves. The data used for these proposed analyses will come two sources. The Health and Retirement Study (HRS) is an ongoing, nationally-representative public use panel study sampling individuals aged 51 and older. In addition, the Hispanic Established Populations for the Epidemiological Study of the Elderly (H-EPESE) will be used to validate findings from the HRS, given its large sample of Mexican-Americans. PI: Qui¿ones, Ana R. Relavance of this research to public health: Understanding the trends of disability and decline in old age is of critical importance to health policymakers. In particular, identifying the challenges posed by an aging population with worse health outcomes for some groups relative to others is a necessary social planning instrument. This research proposes to examine the health trends of older White, African-American and Mexican-Americans to determine whether such differential patterns in aging are at play.
