Can moving more cancel out sitting too much?
Do the associations of sedentary time with colorectal cancer risk differ by physical activity level and vice versa? A cross-sectional study of two large population-based surveys.

Surprising Findings
High physical activity reduced CRC risk by up to 92% even among those sitting 8+ hours daily.
Common advice says 'sit less.' This shows you can sit all day and still be protected—if you move enough. It overturns the assumption that reducing sitting is the only solution.
Practical Takeaways
Aim for at least 2000 MET-min/week of physical activity (e.g., 30 min brisk walking 5x/week + 30 min jogging 2x/week) to neutralize the cancer risk from sitting.

People who are more physically active tend to have a lower risk of developing colorectal cancer, while those who spend more time sitting have a higher risk.
Adults who sit for more than 8 hours a day but engage in at least 2000 MET-minutes of physical activity per week have a significantly lower risk of developing colorectal cancer compared to those who are less active.
Adults who are not physically active and sit for more than 8 hours a day have a higher risk of developing colorectal cancer, with the risk being higher in U.S. populations than in Korean populations.
People who engage in at least 2000 MET-minutes of physical activity per week and sit less than four hours per day have a lower risk of developing colorectal cancer compared to those who are less active or more sedentary.
People who sit for long periods and are not physically active may have a higher risk of colorectal cancer, and this risk appears to be even higher for Black and Asian individuals compared to others.
