Sixty-nine children underwent ambulatory blood pressure monitoring and echocardiography.
No difference in age, body mass index, and left ventricular mass index between groups by ambulatory blood pressure monitoring.
One-third of all children had left ventricular hypertrophy.
Ratio of left ventricular hypertrophy in obese significantly higher than in nonobese.
Left ventricular mass index correlated strongly with body mass index z score but not with any blood pressure parameter.
