The Manitoba Centre for Health Policy has released the report - Adult Obesity in Manitoba, which can be downloaded here: http://mchp-appserv.cpe.umanitoba.ca/deliverablesList.html.
From MCHP:
"Obesity doesn't kill people directly but is related to the development of a number of poor health outcomes, including high blood pressure and diabetes. These are important because they cause serious problems themselves, and they're related to heart disease and stroke, which are leading causes of death. The scope of the deliverable is to include the analysis of provincial trends of obesity and related chronic diseases over a 10-year period. The findings indicate the impact on the healthcare system from obese and overweight people may not be as significant as expected. Using nationally-administered health surveys from 1989 to 2008 the study found obesity rates increased in Manitoba. Overall, more than a quarter of people in the province are now considered obese. This report also confirms what's been proven in the past - geography, marital status, employment, age, sex, education, smoking, and physical activity level can influence weight."
