Defining Vitality: Associations of Three Operational Definitions of Vitality with Disability in Instrumental Activities of Daily Living and Frailty among Elderly Over a 3-Year Follow-Up (MAPT Study).

ABSTRACT:

Objectives

This study aimed to examine the associations of three operational definitions of vitality with variation in instrumental activities of daily living (IADL) and frailty over a 3-year follow-up among non-demented, community-dwelling elderly.

Design

Observational study.

Setting and participants

1,679 elderly >70y (64.7% female) participants of the Multidomain Alzheimer Preventive Trial (MAPT).

Measurements

Vitality was defined as a psychological concept using three items from the Geriatric Depression Scale; as a physical construct using the highest quartile for hand grip strength; and as global physiological reservoir using a combination of good physical and cognitive functions. Variables were assessed at baseline, 6, 12, 24 and 36 months of follow-up.
