It is well recognized that both short-term (days) and longer-term (months or years) variations in temperature are associated with variations in risk of morbidity and mortality.
Quantify the burden of diseases from extreme weather
Investigate the effectiveness of public health interventions in reducing the health impact of extreme weather
Information on various meteorological conditions (e.g., temperature, precipitation, humidity) from all weather stations across Ontario is included in ONPHEC1.
ONPHEC studies that have assessed the effects of weather on chronic disease include:
Increased coronary heart disease and stroke-related hospitalizations from cold and hot temperatures in Ontario, Canada
Risk of hospital admissions for hypertensive diseases, diabetes, and arrhythmia attributable to low and high temperatures: a population-based study
Assessment of the impact of cold and hot temperatures on mortality: a population-based study
