^a Glucose concentration cutoff at ≥110 mg/dL: 0 = below cutoff; 1 = above cutoff.

^b HOMA-IR cutoff of ≥2.5 was at the 57th percentile for this population (0 = below cutoff, 1 = above cutoff). The corresponding 57th percentile glucose concentration in this population was 88 mg/dL.

^c Waist circumference cutoff for MetS was >75th percentile when matched for age, sex and race: 0 = below cutoff; 1 = above cutoff.

^d HDL-C cutoff for MetS was <50 mg/dL: 0 = above cutoff; 1 = below cutoff.

^e Triglycerides cutoff for MetS was ≥100 mg/dL: 0 = below cutoff; 1 = above cutoff.

^f BP cutoff for MetS: sBP and/or dBP >90th percentile when matched for age, sex, and height: 0 = below cutoff; 1 = above cutoff.
