Overweight and obese make up majority in Ontario

Overweight and obese make up majority in OntarioNew analysis of a landmark health survey by the University of Ottawa Heart Institute (UOHI) shows that 70% of Ontario adults are either overweight or obese, and have a strong prevalence of high blood pressure that could lead to heart attack or stroke. The research, led by Dr. Frans Leenen of the Heart Institute's Hypertension Unit, adds new information to a limited amount of Canadian data on obesity and high blood pressure. The analysis further strengthens the link between high blood pressure and above normal Body Mass Index (BMI), a formula for body composition calculated by height and weight. "Obesity is rapidly increasing in Canada because we are eating far more than our bodies require. We know better than ever that even being overweight creates other problems such as diabetes and high cholesterol levels and thereby endangers cardiovascular health," said Dr. Leenen. "Public health strategies to reduce the growing epidemic of obesity would also reduce the burden of high blood pressure and other negative effects leading to heart disease." Study results were published this week in the American Journal of Hypertension (AM J Hypertens 2010; 23: 1000-1006). They represent the latest analysis from the Ontario Survey on the Prevalence and Control of Hypertension, the first comprehensive assessment of high blood pressure in Canada since 1992
