Correlates of extended sitting time in older adults: an exploratory cross-sectional analysis of the Canadian Community Health Survey Healthy Aging Cycle.
OBJECTIVE
Sitting time has been identified as an independent predictor of health; however, little is known of the determinants of extended sitting time among older adults. The purpose of this study was to identify potential sociodemographic, physical environment, health-related and psychosocial correlates of extended sitting time among older adults living independently in the community.


METHODS
Data from adults over the age of 65 from the Canadian Community Health Survey (Healthy Aging Cycle, 2008-2009) were used for analysis (n = 14,560). Self-reported sitting time (<4 or ≥4 h/day) was the main outcome.


RESULTS
Age, retirement status, dwelling type, chronic disease, perceived health, body mass index, mood disorder and sense of belonging to community were associated with sitting for 4 or more hours/day. Very low, but not low or moderate, physical activity (OR 1.43; CI 1.19-1.72) was associated with sitting for 4 or more hours/day when compared to those classified as having high physical activity.


CONCLUSIONS
Several specific correlates of extended sitting time were identified among older males and females; these findings have implications for public health strategies targeting older adults.
