Minority Predoctoral Fellowship Program

描述（由申请人提供）：拟议研究的目的是使用残疾过程模型来检查社区特征影响老年墨西哥裔美国人残疾发展和死亡风险的机制。该项目将使用来自西班牙裔老年人流行病学研究（Hispanic EPESE）的纵向数据，这是一个居住在西南五个州的3050名老年墨西哥裔美国人的概率样本。这些数据将进行地理编码，并与1990年和2000年美国人口普查数据合并。主要结局包括残疾和死亡率，次要结局包括医疗状况、认知和感觉障碍以及下肢功能。以下是拟议项目的具体目标：目标1。确定社区社会经济特征和社区同化（墨西哥裔美国人较低的集中百分比）是否与残疾过程模型（病理>>>损伤>>>功能限制>>>残疾）和死亡率阶段相关。目标2。确定1990年至2000年间墨西哥裔美国人的社区社会经济特征和百分比集中度的变化是否与残疾过程模型的各个阶段（病理b> b>损伤>>>功能限制>>>残疾）和死亡率相关。

DESCRIPTION (provided by applicant): The purpose of the proposed research is to use the Disablement Process model to examine mechanisms through which neighborhood characteristics influence the development of disability and the risk of mortality in older Mexican Americans. This project will use longitudinal data from the Hispanic Established Population for the Epidemiological Study of the Elderly (Hispanic EPESE), a probability sample of 3,050 older Mexican Americans residing in five southwestern states. These data will be geocoded and merged with 1990 and 2000 US Census data. Primary outcomes include disability & mortality while secondary outcomes include medical conditions, cognitive & sensory impairments, and lower body function. The following are specific aims for the proposed project: Aim 1. Determine whether neighborhood socioeconomic characteristics and neighborhood assimilation (lower percent concentration of Mexican Americans) are associated with stages of the Disablement Process model (pathology >>> impairment >>> functional limitation >>> disability) and mortality. Aim 2. Determine whether changes in neighborhood socioeconomic characteristics and percent concentration of Mexican Americans between 1990 and 2000 correlate with stages of the Disablement Process model (pathology >>> impairment >>> functional limitation >>> disability) and mortality.
