Sedentary Behavior and Physical Functioning in Middle-Age and Older Adults Living in the United States: The Reasons for Geographic and Racial Differences in Stroke Study.

ABSTRACT:

Purpose

Sedentary behavior is associated with poor physical function in older adults, which can lead to accelerated skeletal muscle aging (sarcopenia) and premature mortality. We examined the independent and joint effects of sedentary behavior and moderate to vigorous intensity physical activity (MVPA) with measures of physical functioning.

Methods

We studied 5408 participants in the REasons for Geographic and Racial Differences in Stroke study who wore a hip-mounted accelerometer over seven consecutive days (2009-2013) and had self-reported and directly observed physical function (time walk, chair stand test) measured during an in-home visit conducted from 2013 to 2016.

Results

Greater sedentary time was significantly associated with poorer chair stand and timed walk
