Diabetes Mellitus (DM) was listed as the primary cause for 929 deaths in Simcoe Muskoka between 2007 and 2012 and was the sixth leading cause of death during that time period. Mortality figures that are based on diabetes as the primary cause of death underestimate the true impact of diabetes on mortality. This is because the medical complications associated with diabetes put individuals with the disease at increased risk of premature death compared to people without the illness. According to a 2011 report produced by the Public Health Agency of Canada, at least one in ten adult deaths can be attributed to diabetes. However, the DM mortality rate based on primary cause of death remains a commonly used indicator at the provincial, national and international levels.
The age-standardized mortality rate for DM in Simcoe Muskoka for all ages and sexes in 2012 was 26.0 (21.8, 30.1) per 100,000 population, which was significantly higher than the Ontario rate of 20.4 (19.6, 21.1) per 100,000 population.
