  1. CHMS Canadian Health Measures Survey; HAC: Healthy Alberta Communities
  2. aValues were adjusted for age, community of residence, smoking status, physical activity level, fruit and vegetable consumption, self-reported health, and self-reported BMI
  3. bTotal household population aged 18 to 79, except those meeting the CHMS exclusion criteria [78]
  4. cValues are from the CHMS cycle 1 data tables [30]
  5. dValues are from the CHMS cycle 2 data tables [11]
  6. eBlood pressure (BP) was classified as normal (systolic BP < 130 mmHg and/or diastolic BP < 85 mmHg), high-normal (systolic BP = 130–139 mmHg and/or diastolic BP = 85–89 mmHg), or stage 1 hypertension (systolic BP = 140–159 mmHg and/or diastolic BP = 90–99 mmHg) [32]
  7. fUse with caution, data with a coefficient of variation from 16.6 % to 33.3 % [11, 30]
  8. gBMI was calculated from measured height and weight and classified as: normal weight (18.5–24.9 kg/m2), overweight (25.0–29.9 kg/m2), obese class I (30.0–34.9 kg/m2), obese class II (35.0–39.9 kg/m2), and obese class III (≥40.0 kg/m2) [33]
  9. n/aToo unreliable to be published, data with a coefficient of variation >33.3 %, suppressed due to extreme sampling variability [11, 30]
