Abbreviations: CI, confidence interval; yrs, years.

Body mass index (weight in kilograms divided by height in meters squared) estimates were calculated from self-reported weight and height. Underweight and normal weight = BMI <25, overweight = BMI 25.0–29.9, and has obesity = BMI ≥30.

Physical activity level definitions: active (meeting the aerobic physical activity guideline of 150 minutes/week of moderate-intensity physical activity, 75 minutes/week of vigorous-intensity physical activity, or an equivalent combination); insufficiently active (some activity, but not enough to meet active definition); and inactive (no leisure-time physical activity for at least 10 minutes).
