900,000 Days in Hospital: The Annual Impact of Smoking, Alcohol, Diet and Physical Activity on Hospital Use in Ontario


This report describes the proportion of Ontario adults at risk for four health behaviours—smoking, unhealthy alcohol consumption, poor diet and physical inactivity—and estimates the impact of these behaviours on hospital use and hospital costs in Ontario in 2011.

The researchers have created an online calculator to help Ontarians estimate their life expectancy and the amount of time they might expect to spend in hospital due to their habits and lifestyle choices.
