Adherence
High levels of sedentary behavior (defined as sitting or lying down with energy expenditure of 1.0-1.5 basal metabolic rates) are strongly associated with increased all-cause mortality, cardiovascular disease, and type 2 diabetes in adults, independent of physical activity levels.
If you have a desk job, prioritize breaking up long periods of sitting. The risk of heart disease and early death increases with sitting time even if you exercise. Stand up, walk, or move frequently throughout the day rather than relying solely on your gym session to protect your health.
GoodSupportsHIGH confidence
In adults, we found strong evidence of a relationship between sedentary behavior and all-cause mortality, fatal and non-fatal cardiovascular disease, type 2 diabetes and metabolic syndrome.
Why this rating
Based on systematic reviews of prospective studies with high methodological quality, though causality is inferred from observational data.
