Sedentary behavior is associated with increased mortality and cardiometabolic risk, independent of moderate-to-vigorous physical activity levels, but causal direction remains uncertain due to reliance on self-reported data.
Even if you exercise regularly, try to break up long periods of sitting. Stand up, move around, or perform light activities frequently throughout the day to mitigate potential risks associated with prolonged sedentary time.
ModerateSupportsMEDIUM confidence
a growing body of epidemiological literature over the past 5–10 years has described the associations between sedentary behaviour and increased risks of all-cause mortality and cardiometabolic diseases... with plausible biological mechanisms (eg, lipoprotein lipase regulation) proposed from animal studies.
Why this rating
The paper reviews observational studies with limitations in measurement (self-report) and design (cross-sectional).

More from this paper
- Accelerometers provide objective, feasible measurements of physical activity and sedentary behavior in large-scale epidemiological studies, overcoming the limitations of self-report.Good
- Current physical activity guidelines exclude light-intensity activity because existing evidence relies on imprecise self-reports rather than objective data, not because light-intensity activity lacks health benefits.Moderate
