Obesity, diet and functional health in African-Americans

描述（由申请人提供）：到2050年，非裔美国老年人口将增加两倍以上。目前的证据表明，功能健康下降在这一群体中比一般美国人更常见，但对可改变的风险因素知之甚少，这些因素可以减少观察到的功能健康下降。本研究的目的是确定非裔美国男性和女性的体重、脂肪分布、饮食质量和饮酒与功能性健康的关系。功能性健康与感兴趣的暴露之间的关联将被横断面、前瞻性和作为平均年变化的函数进行检查。本研究的数据将来自社区动脉粥样硬化风险（ARIC）队列。1996-1998年，参加第4次访问检查的1 616名非裔美国妇女和877名54-73岁非裔美国男子提供了有关功能性健康的信息。功能性健康将通过下肢功能、日常生活活动（ADLs）和日常生活工具活动（ADLs）进行评估。其他可获得的数据包括：共4项体重、身高、腰围和臀围，以及在就诊4之前和就诊4时每3年收集一次的饮酒量；25岁时的体重报告；并在第一次访问时（结果测量前9年）进行66项食物频率问卷调查。

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 ....
