Minority Predoctoral Fellowship Program

描述(由申请人提供)：拟议的研究目的是使用残疾过程模型来检查社区特征通过哪些机制影响墨西哥裔美国老年人的残疾发展和死亡风险。该项目将使用西班牙裔老年人流行病学研究(西班牙裔EPESE)的纵向数据，这是居住在西南部五个州的3050名老年墨西哥裔美国人的概率样本。这些数据将被地理编码，并与1990年和2000年美国人口普查数据合并。主要结果包括残疾和死亡率，而次要结果包括医疗条件、认知和感觉障碍以及下半身功能。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(墨西哥裔美国人的百分比较低)是否与残疾进程模式的阶段(病理和功能障碍)和死亡率有关。目的2.确定1990至2000年间墨西哥裔美国人社区社会经济特征和集中度的变化是否与残疾进程模式的阶段(病理和功能障碍)和死亡率有关。

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.
