title: Sedentary Behavior and Cardiovascular Risk in Older Adults: a Scoping Review.
abstract: Sedentary behavior is an emerging risk factor for cardiovascular disease (CVD) and may be particularly relevant to the cardiovascular health of older adults. This scoping review describes the existing literature examining the prevalence of sedentary time in older adults with CVD and the association of sedentary behavior with cardiovascular risk in older adults. We found that older adults with CVD spend >75 % of their waking day sedentary, and that sedentary time is higher among older adults with CVD than among older adults without CVD. High sedentary behavior is consistently associated with worse cardiac lipid profiles and increased cardiac risk scores in older adults; the associations of sedentary behavior with blood pressure, CVD incidence, and CVD-related mortality among older adults are less clear. Future research with larger sample sizes using validated methods to measure sedentary behavior are needed to clarify the association between sedentary behavior and cardiovascular outcomes in older adults.
