Mortality in Relation to Changes in a Healthy Aging Index: The Health, Aging, and Body Composition Study

Baseline scores on a Healthy Aging Index (HAI), including five key physiologic domains, strongly predict health outcomes. This study aimed to characterize 9-year changes in a HAI and explore their relationship to subsequent mortality. Data are from the Health, Aging, and Body Composition study of well-functioning adults aged 70–79 years.
