Sedentary Behavior and Physical Activity Are Independent Predictors of Successful Aging in Middle-Aged and Older Adults

Abstract

Background. Sedentary behavior is emerging as an important risk factor for poor health. Physical activity has proven to be important in determining overall successful aging (SA) among older adults; however, no data exists on the influence of sedentary behavior on SA. The purpose of this analysis was to determine whether there is an association between sedentary behavior and successful aging, independent of physical activity levels. Methods. 9,478 older (M = 4,245; F = 5,233) and 10,060 middle-aged (M = 4.621; F = 5,439) adults from the Healthy Aging cycle of the Canadian Community Health Survey were analyzed. Multivariate logistic regressions were conducted with SA and its three components as outcomes while physical activity and sedentary behavior were entered as main exposures. Results. Among older adults, compared to those who were sedentary (4 hours or more/day), those who were moderately (2–4 hours/day) and least sedentary (<2 hours/day) were 38% (OR: 1.38; CI: 1.12–1.69) and 43% (OR: 1.43; CI: 1.23–1.67) more likely to age successfully, respectively. Among middle-aged adults, those who were least sedentary were 43% (OR: 1.43; CI: 1.25–1.63) more likely to age successfully. Conclusions. These novel findings suggest that sedentary activities are significantly associated with lower odds of SA among middle-aged and older adults, potentially in a dose-dependent manner.

Guidelines for Adult Stroke Rehabilitation and Recovery

“…Less sedentary behavior has been found to be an independent predictor of successful aging among individuals ≥45 years of age. 781 Moreover, prolonged bouts of sedentary behavior and total amount of physical inactivity appear to be independently related to risk factors associated with metabolic syndrome (eg, increased waist circumference, body mass index, triglycerides, and plasma glucose). 782 To date, little research has been conducted on patterns of sedentary behavior after stroke.…”

“…A cohort study reported that people after stroke (n=25) spent less time being physically active and had fewer breaks in sedentary behavior at 1 week, 3 months, and 6 months after stroke compared with nondisabled control subjects matched by age, sex, and body mass index. 781 Intervention strategies are needed to break the relentless poststroke cycle of reduced physical activity leading to further reductions in functional capacity and heightened risk of secondary complications. The central role that aerobic exercise plays in improving cardiorespiratory fitness is well known and strongly supported by evidence.…”

“…25 For this study, data collected during sleep were excluded. Using the energy expenditure (EE) data from the SWA, we categorized PA intensity into three levels: mild, moderate, and vigorous PA. 26 Mild PA consisted of activities yielding an EE of 1.6-2.9 metabolic equivalents (METs); moderate PA, an EE of 3.0-4.9 METs; and vigorous activity, an EE of 5.0 METs or more. 27,28 Procedures…”

When More Than Exercise Is Needed to Increase Chances of Aging in Place: Qualitative Analysis of a Telehealth Physical Activity Program to Improve Mobility in Low-Income Older Adults (Preprint)

“…[2] The World Health Organization calls for a 10% increase in physical activity (PA), and encourages community-based collaborations to formulate evidence based, cost-effective means to achieve this goal. [3] PA can decrease the chance of falls, [4] cardiovascular disease, [5] and arthritis pain. [6][7][8] PA can increase memory performance [9] and improve functioning with arthritis.…”
