<p>The Health Aging and Body Composition (Health ABC) Study is a NIA-sponsored cohort study of the factors that contribute to  incident disability and the decline in function of healthier older persons, with a particular emphasis on changes in body composition  in old age.  Between 4/15/97 and 6/5/98 the Health ABC study has recruited 3,075 70-79 year old community-dwelling adults  (41% African-American), who were initially free of mobility and activities of daily living disability. The key components of  Health ABC include a baseline exam, annual follow-up clinical exams, and phone contacts every 6 months to identify major health  events and document functional status between clinic visits.</p>  <p>The core yearly examination for HEALTH ABC includes measurement of body composition by dual energy x-ray absorptio-metry (DXA),  walking ability, strength, an interview that includes self-report of limitations, and a medication survey, weight. At baseline, visceral  adiposity was measured by computerized tomography (CT). Provision has been made for banking of blood specimens and extracted DNA  (HealthABC repository). The overall goal of this project is to identify genetic determinants of visceral adiposity. Genetic samples  from 2932 unrelated participants were evaluated with a genome-wide scan.</p>
