Life Expectancy Calculator
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. We calculat ed the risk of death for Ontarians who responded to Canadian Community Health Surveys from 2001 to 2008 and agreed to have their responses linked to their personal health information. There were approximately 1 million person-years of follow-up and over 9000 deaths in the development and validation datasets. The study adjusted for a wide range of risk factors, in addition to health behaviours and was published in PLoS Medicine.

The original life expectancy calculator was developed using Canadian Community Health Surveys from 2001 to 2005 (550 000 person-years of follow-up, with over 6000 deaths). For more information about the original study see www.publichealthontario.ca or www.ices.on.ca.

Stroke Calculator
The stroke calculator was created with the Stroke Population Risk Tool (SPoRT). SPoRT is a predictive risk algorithm that estimates the risk of hospitalized stroke based on healthy living and other sociodemographic and health indicators. Risk of stroke was assessed for 82 259 Ontarians who responded to Canadian Community Health Surveys from 2001 to 2005 and agreed to have their responses linked to their personal health information. People were followed for over 668 000 person years, with over 3 236 incident stroke events observed. The study adjusted for a wide range of risk factors, in addition to smoking, physical activity, diet, alcohol and stress. For more information, see the PLoS One Study here.

Health Care Cost Calculator
The health use calculator was based on the largest study to directly link healthy living and sociodemographic indicators to comprehensive health care. Health care costs for hospital, drugs, physician services and other government-funded health care were examined for 80,000 Ontarian respondents of the Canadian Community Health Survey who agreed to have their responses linked to their personal health information. In total, there was $430 billion in Ontario government-funded health care from 2004 to 2013. We observed a $4.9 Billion decrease in health care expenditure from improving healthy living over the ten-year study. For more information, see the report here.

Air Pollution for Life Expectancy Calculator
The effect of long-term exposure to air pollution and risk of dying was examined for over 2.5 million Canadian adults who completed the 1991 long-form census. People were followed for over 36 million person-years, with over 300 000 deaths observed. Residential postal codes of person for each year, during sixteen years of follow-up, allowed Dr. Crouse and his collaborators to estimate each person’s exposure to fine particulate matter (PM2.5), ozone (O3), and nitrogen dioxide (NO2). Annual average pollutant concentrations were derived from data from ground-based air pollution monitors, satellite measurements, and atmospheric models. For more information about the study see ehp.niehs.nih.gov.

Nursing Home Calculator
The nursing home calculator was developed using a statistical model to estimate the risk of death and hospital admission for 53,739 people newly admitted to long-term care facilities in Ontario. We measured adjusted rates of hospital admissions and mortality, per 1000 person-years (PY) of follow-up, among for-profit and not-for-profit facilities at 3, 6, and 12 months post-admission. Rates were measured post-admission and until discharge or death, whichever came first. See www.jamda.com.

Hospital Use Calculator
900,000 Days in Hospital: The annual impact of smoking, alcohol, diet, and physical activity on hospital use in Ontario. The hospital use calculator is from this report. For more information see www.ices.ca.
