Chronic Diseases and Injuries

Chronic diseases are the leading cause of death and disability in Ontario. Four risk factors (unhealthy eating, physical inactivity, harmful use of alcohol, and tobacco use) are major contributors to the burden of chronic diseases, such as cancer, cardiovascular disease, respiratory disease, and diabetes. In addressing chronic diseases and their risk factors, public health must consider health equity and the socio-ecological context.

Injury prevention is an important public health as preventable injuries from falls, motor vehicle collisions, alcohol and substance misuse, drowning, pedestrian injuries, poisoning and burns are a leading cause of morbidity and mortality among children and youth.
