Diabetes in Canada: An interactive report on key statistics: Technical notes

Prevalence of individuals aged 18-79 years with diabetes (self-reported, measured, medication use) who had measured systolic blood pressure/diastolic blood pressure below 130/80 mm Hg.

Types of diabetes are combined. Gestational diabetes, pregnant women and respondents with missing laboratory blood test data are excluded.

Obesity: Prevalence of individuals aged 18 years and older with/without diabetes (self-reported) with an adjusted BMI greater or equal to 30.0 kg/m².

Overweight: Prevalence of individuals aged 18 years and older with/without diabetes (self-reported) with an adjusted BMI score greater or equal to 25.0 kg/m² but less than 30.0 kg/m²

BMI calculations are based on self-reported height and weight and adjusted to respondent bias to more closely approximate measured values.
