*All children underwent a detailed physical examination by a pediatric endocrinologist (that included assessment of blood pressure and skin sensitivity), specific serum and urinary biochemical tests (including a complete renal function and microalbuminuria), and complete ophthalmic evaluation. ** According to CDC growth charts (Kuczmarski and cols., 2002 [30]) adapted for Brazilian children (Silva and cols., 2010 [31]). *** Children not presenting Tanner stage M1P1 (females) or G1P1 (males) were excluded. **** Blood pressure was measured with suitable cuffs and classified according to systolic and diastolic curves, specific for each age, gender, and height, in agreement with the curves of the Second Task Force on Blood Pressure Control in Children (1996). High blood pressure was diagnosed when the percentiles of systolic and/or diastolic readings were above the 95th percentile for age and sex, on at least three occasions. If the readings were between the 90th and 95th percentiles, the blood pressure was considered to be normal-high, and when below the 90th percentile, it was considered normal.
