Canada Obesity Trends
According to Statistics Canada’s published data for 2005, the rate of Canadians in the obese category (BMI higher than 30kg/m2) has almost doubled between 1978 and 2005, rising from 13.8% to 24.3% of the adult population that is almost 1 in 4 individuals. In 2005, the number of obese Canadians 18 or older was 5.5 million; 36% of the adult population was considered overweight; and 39% had a healthy weight. Underweight individuals represented 2% of the population.
In Québec, the proportion of obese individuals was 22% in 2004. Even though this is still lower than the national percentage, the gap is rapidly being filled. The Montréal and Québec regions are less affected, whereas Abitibi-Témiscamingue, Outaouais and the Gaspé peninsula are the most affected. British Columbia is the only province with obesity prevalence lower than Québec’s.
Over the last decade in the United States, the increase in obesity has been definitely more significant that in Canada. The American statistics show, using measuring tools similar to those used in Canada, that 30% of the adult population (18 or older) was considered obese in 2004.
