Adherence
There is moderate evidence that sedentary behavior is associated with the incidence of endometrial, colon, and lung cancer, but insufficient evidence to determine if bout length or breaks in sedentary behavior are associated with health outcomes.
Sedentary behavior is linked to higher rates of colon, lung, and endometrial cancer. While we don't yet know if 'breaking up' sitting time helps, reducing your total sitting time is a prudent step for cancer prevention.
GoodSupportsMEDIUM confidence
Moderate evidence indicated sedentary behavior is associated with incident endometrial, colon and lung cancer. Evidence was insufficient to determine if bout length or breaks in sedentary behavior are associated with health outcomes.
Why this rating
Graded as 'moderate' evidence for cancer incidence.

- High amounts of sedentary behavior increase the risk of all-cause mortality, cardiovascular disease (CVD) mortality, and incident type 2 diabetes, with evidence graded as strong for these associations.Strong
- The hazardous effects of sedentary behavior on mortality are more pronounced in physically inactive people, and high levels of moderate-to-vigorous physical activity (MVPA) can attenuate but not fully eliminate the risk associated with high sedentary time.Strong

- Regular physical activity (at least 150 minutes/week of moderate-intensity) reduces all-cause and cardiovascular mortality by 20-30% and lowers the risk of type 2 diabetes by 25-35%.Strong
- Increasing physical activity from a sedentary lifestyle to an active one in middle adulthood significantly reduces the risk of coronary events compared to remaining sedentary.Strong
- Resistance exercise is the only intervention capable of consistently restoring muscle function and strength in sarcopenia, partially overcoming age-related anabolic resistance.Strong
