Prolonged Leisure-Time Sitting Tied to Increased Mortality Risk
Increase in all-cause, cardiovascular disease, cancer, diabetes, kidney disease, suicide, COPD mortality
FRIDAY, June 29, 2018 (HealthDay News) -- Prolonged leisure-time sitting is associated with increased risk of mortality, according to a study published online in the American Journal of Epidemiology.
Alpa V. Patel, Ph.D., from the American Cancer Society in Atlanta, and colleagues examined the correlations of leisure-time sitting with risk of specific causes of death. Data was used from a prospective U.S. cohort including 127,554 men and women who were free from major chronic disease at study entry. During 21 years of follow-up (1993 to 2014), 48,784 people died.
The researchers found that prolonged leisure-time sitting (6+ hours versus <3 hours/day) correlated with increased risk of all-cause, cardiovascular disease, cancer, diabetes, kidney disease, suicide, chronic obstructive pulmonary disease, pneumonitis due to solids and liquids, liver and other digestive disease, Parkinson's disease, Alzheimer's disease, nervous disorders, and musculoskeletal disorders mortality after multivariable adjustment. The association was independent of moderate-vigorous activity level.
"These findings provide additional evidence for associations between a broad range of mortality outcomes and prolonged sitting time," the authors write. "Given the pervasive nature of sitting in contemporary lifestyle, this study further supports that encouraging individuals to reduce sedentary time may provide health benefits."
