We investigated the aggregation of the tracking effect of blood pressure (BP) with overweight and metabolic abnormalities in young subjects followed-up for a 10-year-period (The Rio de Janeiro Study). 215 young subjects (116M) had their BP and body mass index (BMI) obtained at their schools in 1987/88 (12.69±1.65y) and at the hospital in 1997/98 (21.60±2.01y). BP was measured 3 times, and the third measure was used for analysis. Subjects were considered normotensive when BP percentile was ≤ 50 at school or < 140/90 mmHg at the hospital; hypertensive when BP percentile ≥ 95 at school or ≥ 140/90 mmHg at the hospital. The cut-off points for BMI were 85th percentile at school or 25 kg/m2 at the hospital. Cholesterol (C), tryglicerides (TG), LDL-C, HDL-C, glucose and insulin (I) were measured after 12h of fasting, at the hospital. The main results were: 1) After 10 years, 95 (93.1%) normotensive remained normotensive (GI); 38 (34.9%) hypertensive remained hypertensive (G2); 7 normotensive became hypertensive (G3) and 71 hypertensive became normotensive (G4); 2) In G1, 81.1% remained without overweight; in G2, 31.6% remained overweight and 26.3% became overweight; in G3, 28.6% remained overweight; and in G4, 60.6% remained without overweight and 12.7% were no longer overweight (χ2=43.89, p
