Abstract

Abstract: Neighborhood characteristics are associated with self-reported sedentary behavior (SB) in older adults. However, self-report measures are not able to accurately assess total sitting time nor detailed patterns of SB. This analysis explores the relationship between device-based SB variables from activPAL and neighborhood characteristics (demographics) in the ACT cohort. Neighborhood characteristics were assessed with the modified Physical Activity Neighborhood Environment Scale (PANES; scored 1.0-4.0, higher score, higher walkability). Data were analyzed using linear regression models adjusted for demographic factors. Higher PANES score was associated with higher daily steps (+1180 daily steps/point on PANES, p<0.001) and sit-to-stand transitions (+2.7 daily transitions/point on PANES, p=0.004). Confirming other studies, neighborhood walkability promotes physical activity. A novel finding was that sitting interruptions, which can only be assessed with devices, were also associated with higher neighborhood walkability, while total sitting time was not.
