From: The association between obesity and blood pressure in Thai public school children

Criteria BMI for age and gender p-value WC p-value
Under weight Normal Over weight Obese < P75 ≥ P75
Normal 62 (100.0) 375 (96.9) 102 (97.1) 106 (73.1) < 0.001 508 (97.3) 131 (76.6) < 0.001
Pre-hypertension 0 (0.0) 6 (1.6) 2 (1.9) 19 (13.1)   9 (1.7) 18 (10.5)  
Hypertension 0 (0.0) 6 (1.6) 1 (1.0) 20 (13.8)   5 (1.0) 22 (12.9)  
  1. Data are presented as n (%) and were calculated by χ2 test. SBP, systolic blood pressure and DBP, diastolic blood pressure ≥ P90 but less than P95 was defined as pre-hypertension; ≥ P95 was defined as hypertension with boys and girls.
