Background: The higher risk of death resulting from excess adiposity may be attenuated by
physical activity (PA). However, the theoretical number of deaths reduced by eliminating
physical inactivity compared with overall and abdominal obesity remains unclear. Objective:
We examined whether overall and abdominal adiposity modified the association between
PA and all-cause mortality and estimated the population attributable fraction (PAF) and the
years of life gained for these exposures. Design: This was a cohort study in 334,161 …
