Seven More Years: The Impact of Smoking, Alcohol, Diet, Physical Activity and Stress on Health and Life Expectancy in Ontario


This report examines the burden of five behavioural health risks—smoking, unhealthy alcohol consumption, poor diet, physical inactivity and high stress—and their impact on life expectancy and health-adjusted life expectancy in Ontario. The findings of this joint study by ICES and Public Health Ontario expand our understanding of healthy living by quantifying the impact of the five health risks on Ontarians’ overall health.
