Data are % (95% CI).
Non-Asians were categorized as underweight (BMI <18.5 kg/m2), normal weight (18.5–24.9 kg/m2), overweight (25.0–29.9 kg/m2), and obese class 1–4 (30.0–34.9, 35.0–39.9, 40.0–49.9, ≥50.0 kg/m2), and Asians were categorized as underweight (<18.5 kg/m2), normal weight (18.5–22.9 kg/m2), overweight (23.0–27.4 kg/m2), and obese class 1–4 (27.5–32.4, 32.5–37.4, 37.5–47.4, ≥47.5 kg/m2).
P for trend across BMI categories was adjusted for multiple comparisons using the FDR method.
