*BMI categories: normal (BMI 18.5–24.9), overweight (BMI 25.0–29.9), obese (BMI ≥ 30.0), obese class I (BMI 30.0–34.9), obese class II (BMI 35.0–39.9) and obese class III (BMI ≥ 40.0).
†Data with a coefficient of variation from 16.6%–33.3% should be interpreted with caution. 
‡Data suppressed because of extreme sampling variation.
