Abstract

This study predicted all-cause mortality based on physical activity level (active or inactive) and waist circumference (WC) in 8208 Canadian adults in Alberta, Manitoba, Nova Scotia, and Saskatchewan, surveyed between 1986–1995 and followed through 2004. Physically inactive adults had higher mortality risk than active adults overall (hazard ratio, 95% confidence interval = 1.20, 1.05–1.37) and within the low WC category (1.51, 1.19–1.92). Detrimental effects of physical inactivity and high WC demonstrate the need for physical activity promotion.
