*Oral glucose tolerance test was performed in 194 children; disturbed glucose metabolism was defined in the other children by impaired fasting glucose or hyperinsulinaemia (⩾15 mU/l for prepubertal children, ⩾30 mU/l for pubertal children, ⩾20 mU/l for postpubertal children).
BP, blood pressure; chol, cholesterol; WC, waist circumference.
