Adverse associations of sedentary behavior with cancer incidence and all-cause mortality: A prospective cohort study.

ABSTRACT:

Background

Inconsistent results have been reported in developed countries for relationships between sedentary behavior and cancer incidence and mortality, and evidence from the Chinese population is scarce.
