Obesity, diet and functional health in African-Americans

描述（由申请人提供）：到2050年，非洲裔美国老年人口将增加两倍以上。目前的证据表明，功能健康的下降在这一群体中比一般美国人更常见，但对可以减少观察到的功能健康下降的可改变的风险因素知之甚少。本研究的目的是确定非裔美国男性和女性的功能健康与体重，脂肪分布，饮食质量和饮酒量的关系。功能性健康与相关暴露之间的关联将进行跨部门、前瞻性的研究，并作为平均年度变化的函数。本研究的数据将来自社区动脉粥样硬化风险（ARIC）队列。参加第4次访视检查（1996-1998年）的1 616名非裔美国妇女和877名非裔美国男子提供了有关功能健康的信息，年龄在54-73岁之间。将使用下肢功能、日常生活活动（ADL）和工具性日常生活活动（ADL）评估功能健康。其他可用数据包括：在访视4之前和访视4时，在9年内以3年的间隔收集体重、身高、腰围和臀围以及饮酒量的总共4个测量值;在25岁时报告体重;以及在访视I时（在结果测量之前9年）进行的66项食物频率问卷。 本提案直接响应PA-01-082，以“......支持研究人员有兴趣进行二次数据分析的数据有关...关于衰老的行为研究”和“...关于老龄化进程和老年人健康和死亡率决定因素的流行病学研究.。"

DESCRIPTION (provided by applicant): The African American elderly population will more than triple by the year 2050. Current evidence indicates that declines in functional health are more common in this group than in Americans in general, yet little is known about modifiable risk factors that could reduce the observed declines in functional health. The purpose of this research is to determine associations of functional health with body weight, fat distribution, diet quality and alcohol consumption in African American men and women. Associations between functional health and the exposures of interest will be examined cross-sectionally, prospectively, and as a function of mean annual changes. Data for this study will come from the Atherosclerosis Risk in Communities (ARIC) cohort. Information on functional health is available from 1,616 African American women and 877 African American men ages 54-73 years who participated in the visit 4 examination (1996-1998). Functional health will be assessed using lower extremity function, activities of daily living (ADLs), and instrumental activities of daily living (ADLs). Other data available include: a total of 4 measures of weight, height, waist and hip circumference, and alcohol consumption collected at 3 year intervals over 9 years prior to visit 4 and at visit 4; reported weight at age 25; and a 66-item food frequency questionnaire administered at visit I (9 years prior to the outcome measures). This proposal is directly responsive to PA-01-082 to "... suport researchers interested in undertaking secondary data analyses of data related to ... behavioral research on aging" and "... epidemiological research on the aging process and on the determinants of health and mortality in older populations ....
