Diabetes occurs when the body does not produce enough insulin, or when the insulin produced is not used effectively. Diabetes may lead to a reduced quality of life as well as complications such as heart disease, stroke and kidney disease.Note 1
Survey respondents were asked to report if they had been diagnosed with diabetes by a health professional. Included in the rates were:
- type 1, which is usually diagnosed in children and adolescents;
- type 2, which usually develops in adulthood; and
- gestational diabetes, which occurs during pregnancy.
In 2014, 6.7% of Canadians aged 12 or older (2.0 million people) reported that they had diabetes. This was not a significant change from 2013, though it was higher than diabetes rates between 2001-2009 and 2011.
Throughout the period from 2001 to 2014, males were more likely than females to report that they had diabetes. In 2014, the rates were 7.5% for males, compared with 5.8% for females (Chart 1).
The rate of diabetes among males and females increased with age up to age 74.Note 2 For those aged 75 or older, the rate did not increase significantly (Chart 2).
In the younger age groups (those aged 12 to 44), males and females had roughly the same rates of diabetes. After the age of 45, males were more likely than females to report a diagnosis of diabetes (Chart 2).
In addition, Canadians 18 or older who were obeseNote 3 were more likely than those who were not obeseNote 3 to report that they had been diagnosed with diabetes. In 2014, 14.6% of obese Canadians 18 or older had diabetes, compared with 5.2% of those who were not obese.
The proportion of residents aged 12 and older who reported being diagnosed with diabetes was lower than the national average (6.7%) in:
- Manitoba (5.6%)
- Alberta (5.0%)
- British Columbia (5.5%)
The proportion of residents who reported being diagnosed with diabetes was higher than the national average in:
- Newfoundland and Labrador (9.0%)
- Nova Scotia (8.2%)
- New Brunswick (8.4%)
- Ontario (7.4%)
Residents of the other provinces and territoriesNote 4 reported rates that were about the same as the national average.
Because diabetes is strongly related to age, provinces and territories with disproportionately younger populations are expected to have lower diabetes rates than the national average. The reverse is true for provinces and territories with older populations. To remove the effect of different age distributions when making provincial comparisons, please refer to the CANSIM table 105-0503 for the age standardized rates.
