Sleep-wake disturbances in sedentary community-dwelling elderly adults with functional limitations.

ABSTRACT:

Objectives

To evaluate sleep-wake disturbances in sedentary community-dwelling elderly adults with functional limitations.

Design

Cross-sectional.

Setting

Lifestyle Interventions and Independence in Elder (LIFE) Study.

Participants

Community-dwelling persons (mean age 78.9) who spent fewer than 20 min/wk in the previous month engaged in regular physical activity and fewer than 125 min/wk of moderate physical activity, and had a Short Physical Performance Battery (SPPB) score of <10 (N = 1,635).

Measurements

Mobility was evaluated according to 400-m walk time (slow gait speed defined as <0.8 m/s) and SPPB score (≤ 7 defined moderate to severe mobility impairment). Physical inactivity was defined according to sedentary time, as a percentage of accelerometr
