Prehypertension in outpatient obese children.

PH was observed in 79 OB children (17.7%) and in 2 (1.5%) controls. Among OB children, those with PH had greater percentage of males (P < 0.05), higher level of body mass index (BMI) (P < 0.001), waist circumference (W c ) (P < 0.005), and HOMAIR (P < 0.001), compared to PH− children. The two groups did not differ for eGFR and LV function. At logistic regression analysis, PH was independently associated with male gender (P < 0.025) and HOMA IR (P < 0.002). Gender analysis showed that boys with PH presented higher levels of BMI (P < 0.005), W c (P < 0.01), HOMA IR (P < 0.001), and triglycerides (P < 0.005) compared to PH − boys. Females with PH were older and in more advanced postpubertal stage, had higher BMI, W c (P < 0.05, for all), and HOMA IR (P < 0.025), compared to PH − girls.
