Longer ‘Sitting’ Times Linked to Higher Cancer Risk for Women

After taking into account body mass index, physical activity and other factors, women who spend more of their leisure time sitting may face a higher cancer risk, according to new research from the American Cancer Society.

The study is based on data collected from more than 146,000 men and women enrolled in the American Cancer Society Cancer Prevention Study II Nutrition Cohort.

For women, longer sitting times were associated with a 10 percent higher risk of all cancers, and multiple myeloma, breast and ovarian cancers, in particular.

No such association was found for men.

The ACS, in their guidelines for cancer prevention, recommends reducing the amount of time spent sitting.

The findings were published in the journal Cancer Epidemiology Biomarkers & Prevention.
