Health, Aging, and Body Composition Study
The objectives of the HEALTH ABC were:
- To assess the association of baseline body weight, lean body mass, body fat, and bone mineral content with incidence of functional limitation, incidence and change in severity of weight-related health conditions, recovery of physical function after an acute event, baseline measures of strength, fitness and physical performance, gender, ethnicity and socioeconomic status;
- To assess the contribution of episodes of severe acute illness in healthier older persons to changes in body weight, bone mineral content, lean body mass and body fat, and the relationship of these episodes to risk of functional limitation and recovery;
- To assess the impact of weight-related comorbid illness on the risk of functional limitation and recovery;
- To assess the ways in which physiologic mediators of change in body composition influence and are influenced by changes in health in older adults and contribute to change in body composition;
- To understand how changes in body composition affect weight-related cardiovascular disease risk factors such as lipids, blood pressure and glucose tolerance;
- To assess the interdependency of behavioral factors, such as nutrition and physical activity, co-morbid health conditions, and their association with change in body composition in old age;
- To provide a firm scientific basis for understanding issues related to weight recommendations in old age through increased knowledge of the potential trade-offs between weight and risk of functional limitation, disability, morbidity and death;
- To provide information critical for developing effective strategies for the maintenance of health in older persons.
