Adherence
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.
If you sit a lot, exercise is crucial to mitigate the risk, but it may not fully erase it. Aim for at least 150 minutes of moderate-to-vigorous activity per week, but also try to stand up and move frequently during the day.

There was strong evidence that the hazardous effects of sedentary behavior are more pronounced in physically inactive people.
Why this rating
Graded as 'strong' evidence for the interaction.

- 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
- 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.Good
