*The denominator varies by condition owing to missing data.
†Overweight = body mass index (BMI) 25–29.9, obese = BMI ≥ 30.
‡Value indicates meaningful effect size (i.e., at least a weak association). Cramér’s phi (denoted as φc) values between 0.10 and 0.20 indicate a weak association, between 0.20 and 0.40 a moderate association, between 0.40 and 0.60 a strong association and above 0.60 a very strong association.
