Abstract excerpt

Background/Objectives: Accelerometry measures older adult (in)activity with high resolution. Most studies summarize activity over the entire wear time. We extend prior work by analyzing hourly activity data to determine how frailty and other characteristics relate to activity among older adults. Methods: Using wrist accelerometry data collected from the National Social Life, Health and Aging Project (n = 651), a...
