2006-07 Findings

People with Diagnosed Diabetes (Prevalence)

• In 2006-07, after adjusting for changes in the age distribution, the age-standardized prevalence of diagnosed diabetes increased by 4% from the previous year, and by 21% from 2002-03 to 2006-07 (Table 1 and Figure 2).
• Approximately 2 million Canadians aged 1 and older, or about 1 in 16, had diagnosed diabetes (2,086,212 overall—993,805 among girls/women and 1,092,407 among boys/ men). (Table 1)
• The prevalence of diagnosed diabetes among Canadians was 6.2% overall (5.9% of girls/ women and 6.6% of boys/men) (Table 1 and Table 2).
• As anticipated, the prevalence of diagnosed diabetes was significantly lower among children and adolescents (0.3%) than adults (6.4%). The prevalence increased with age among adults from about 2% among individuals in their 30's to about 23%, or 1 in 5, adults aged 75 to 79 years (Table 1, Figure 1, and Figure 3).
• After adjusting for differences in age distributions between provinces and territories, the age-standardized prevalence of diagnosed diabetes was found to be higher in: Newfoundland and Labrador, Nova Scotia, Manitoba, and New Brunswick. Prevalence was lower in the west: Alberta, British Columbia, and Saskatchewan. The prevalence for Ontario was higher than the national average, and for Quebec, prevalence was lower than the national average. The prevalence of obesity, among the provinces and territories, followed a similar pattern; lower in the western provinces than the Canadian average (Figure 3).¹
