New data on trends in obesity in Canada

Canadian Medical Association Journal

Peter Katzmarzyk and Caitlin Mason report on their analysis of data from 7 national surveys on the trends in overweight and obesity in the general Canadian population from 1985 to 2003. Although the prevalence of overall obesity is known to have increased, they wanted to see if the same has been true for each of the 3 classes of obesity, especially the more extreme classes. The proportion of Canadians with class II and III obesity has increased, from 1% in 1985 to 4.3 % in 2004, an over 400% increase in 10 years.
