Leisure Time Sitting Risks for Site-Specific Cancers

Are there risks for just sitting?

Publish date:: July 7, 2015

Longer leisure time spent sitting was associated with a higher risk of cancer in women, but not in men. These conclusions are according to a study of 69,260 men and 77,462 women who were cancer-free and enrolled in a cancer-prevention nutrition study. Researchers found:

After adjusting for physical activity, body mass index, and other factors, longer leisure time spent sitting was associated with a 1.10 relative risk (RR) of total cancer in women, but not in men.
In women, sitting time was associated with RRs of:
- 1.65 for multiple myeloma
- 1.10 for invasive breast cancer
- 1.43 for ovarian cancer
In men, there were no associations between sitting time and site-specific cancers.
