The Economic Burden of Excess Weight
Excess Weight is a leading cause of type 2 diabetes in Canada
- 62% of type 2 diabetes is attributable to excess weight.
- 18% is attributable to physical inactivity.
- 8% is attributable to tobacco smoking.
Are Canadians showing any changes in lifestyle choices?
Dr Krueger referred to Canadian Community Health Survey data from 2001 to 2014 for Canadians aged 20 to 64. Indeed, Canadians have made some positive lifestyle changes.
- Tobacco smoking was reduced from 24.8% to 16.2%.
- Physical inactivity was reduced from 55% to 47%.
Excess Weight has remained the biggest challenge
During the same time period, obesity has increased from 15.3% to 20.6%. This is a total of 4,557,000 Canadians. Most importantly, the prevalence of individuals with the highest levels of obesity has more than doubled. Both the health and economic burdens associated with obesity increase dramatically as weight increases.
In the editorial, Dr Krueger highlighted the successful strategies that have been used to reduce tobacco smoking in Canada. Cessation efforts have spanned the past 60 years, and have encompassed taxation, advertising and clinical practice.
