Higher time spent in sedentary behavior is associated with increased risk of all-cause mortality, cardiovascular disease (CVD) morbidity, and CVD mortality in adults, independent of moderate-to-vigorous physical activity (MVPA).

Minimize prolonged sitting. Break up long periods of sitting with light activity or standing. While meeting physical activity guidelines is essential, reducing total sedentary time offers additional cardiovascular protection.

GoodSupportsHIGH confidence
Evidence is accumulating that sedentary behavior might be associated with increased cardiovascular-specific and overall mortality... evidence is still accumulating regarding the strength of the association... and the support for dose-response relationships that demonstrate sedentary behavior to be an independent risk factor for adverse health outcomes.

Why this rating

Based on multiple large prospective cohort studies and meta-analyses, though the authors note that biological mechanisms are still evolving.
