(MPoRT) Mortality Population Risk Tool

"Unhealthy behaviours place a major burden on Canadian life expectancies," said lead author Dr. Doug Manuel, senior scientist at The Ottawa Hospital and professor at The University of Ottawa, and a senior core scientist at the Institute for Clinical Evaluative Sciences (ICES). "This study identified which behaviours pose the biggest threat."

‍
‍The study found:
• 26 % of all deaths are attributable to smoking
• 24 % of all deaths are attributable to physical inactivity
• 12 % of all deaths are attributable to poor diet
• 0.4 % of all deaths are attributable to unhealthy alcohol consumption

‍

The life expectancy calculator was developed using a statistical model to estimate the risk of death associated with smoking, unhealthy alcohol consumption, poor diet, and physical inactivity in Ontario. "Our approach is a new way of measuring the impact of health problems on life expectancy," said Dr. Manuel. "In an era of big data, we should be moving beyond the old methods that have remained largely unchanged for the past 60 years."
