Chronic diseases include heart disease, cancer, stroke, chronic
obstructive pulmonary disease, and diabetes.
Chronic diseases represent a considerable burden to a country’s
health care system, and are often the leading causes of illness and
death. The World Health
Organization (WHO) estimates that in 2005, of the 58 million deaths
worldwide, 35 million (or 60%) were attributable to chronic diseases
(WHO, 2006). This proportion
is slightly lower than the proportion reported by the Centres for
Disease Control (CDC) in the United States. The CDC estimated that
chronic diseases are responsible for 1.7 million deaths in the
United States annually (CDC, 2004), or roughly, 7 in 10 deaths.
In 2004, 70% of the United States’ $1 trillion budget on
health care was spent on management and treatment of chronic
diseases (CDC, 2004). In
Canada, an estimated 60% of Canadians over the age of 12 have at
least one chronic disease (Schultz & Kopec, 2003), and the annual
cost of caring for individuals with chronic disease is estimated to
be $80 billion (Chronic Disease Prevention Alliance of Canada,
2006).
