Longitudinal changes in physical function and physical activity in older adults.

ABSTRACT:

Background

physical function (PF) and physical activity (PA) both decline as adults age and have been linked to negative outcomes, including dementia, depression and cardiovascular diseases. Although declines in each are associated with numerous negative outcomes, the longitudinal relationship between these two measures is unclear.

Objective

to examine the dynamic, bidirectional associations between declines in PF and PA.

Design

prospective cohort.

Setting

the Monongahela-Youghiogheny Healthy Aging Team (MYHAT) study.

Subjects

about 1,404 men and women, 76.96 ± 7.2 years, 62.4% female and 95.2% white.

Methods

over nine annual assessment cycles, PF was evaluated via the timed Up-and-Go task and PA via a self-reported questionnaire. Piecewise latent
