Associations of Accelerometer-Measured Physical Activity With Dementia, Anxiety, and Depression Among Older Adults.

ABSTRACT:

Background

Higher physical activity (PA) is associated with better neuropsychiatric health, but prior studies have been limited by cross-sectional designs, self-reported PA measures, and small numbers of older individuals. We examined associations between baseline and changes in accelerometer-measured moderate-vigorous PA (MVPA) with neuropsychiatric health among individuals aged ≥ 70 years in the National Health and Aging Trends Study.

Methods

We used the average daily minutes of accelerometer-measured MVPA above a validated threshold of 2184 counts per minute as a continuous measure at baseline for the exposure variable. For longitudinal analyses, we categorized change in MVPA as follows: an increase of > 20 min/day over 1 year, a decrease of > 20 min/day over 1 year, and
