FUNCTIONAL STATUS IN MIDDLE AND LATER LIFE HISPANICS

这项以西班牙裔为基础的纵向人群研究的主要目的是 (in特别是墨西哥裔美国人），年龄在50岁及以上， 功能状态和影响的身体或社会风险因素 功能状态 在过去二十年中， 美国老年人的比例和数量正在创造 对慢性病、残疾和其他疾病造成的负担的高度关切 对老年人及其家人和医疗人员造成的 护理系统。 这些人口增长是成比例的 在少数民族中更大：西班牙裔老年人的数量， 例如，在1970年至1990年期间增加了75%。 因为西班牙裔有 糖尿病、高血压和肥胖症的发病率较高， 西班牙裔的健康往往集中在心血管疾病和相关的 中年人的话题。 尽管其发病率很高， 残疾的后果，没有研究已发表的协会 任何这些条件和功能状态或身体状况之间 在中年和晚年的西班牙裔美国人中的表现。 拟议 纵向研究为期四年。 受试者将 随访36个月。 共有700名受试者（ 包括来自墨西哥的100名受访者）。 两项措施 将在基线（t1）和t2时获得。 一个进化的模型 功能将被测试。 该模型包括三个主要阶段， 独立、亚临床残疾和残疾。 描述性 将使用统计学来表征研究人群。 纵向分析各项指标和措施的变化， 使用标准技术进行，例如回归平均值。

The primary aim of this longitudinal population-based study of Hispanics (in particular Mexican Americans) aged 50 and older is to examine functional status and physical or social risk factors that influence functional status. Dramatic increases in the past two decades in the proportion and number of elderly in the United States are creating heightened concern about the burdens posed by chronic disease, disability and functional impairment on the elderly, their families and the medical care system. These population increases have been proportionately greater among ethnic minorities: the number of Hispanic aged, for example, increased by 75% between 1970 and 1990. Because Hispanics have higher prevalence of diabetes, hypertension and obesity, research on Hispanic health has tended to focus on cardiovascular disease and related topics in middle age populations. Despite their high prevalence and disabling consequences, no research has been published on the association between any of these conditions and functional status or physical performance in middle aged and late life Hispanics. The proposed longitudinal study will be conducted over four years. Subjects will be followed for a period of 36-months. A total of 700 subjects (this total includes 100 respondents from Mexico) will be included. Two measures will be obtained: at baseline (t1) and at t2. A model of evolution of function will be tested. This model consists of three primary stages, independence, subclinical disability and disability. Descriptive statistics will be used to characterize the study population. Longitudinal analysis of change of the various indexes and measures will proceed using standard techniques, e.g. regression to the mean.
