Abstract

PURPOSE: The prevalence of childhood obesity has doubled over the last 30 years. Obesity-associated sequelae in the vasculature begins in the early stages of life. The purpose of this study was to investigate how pulse wave velocity (PWV) and ankle brachial index (ABI) change with height, weight and body mass index (BMI) in obese adolescents.
METHODS
Seventy-nine obese adolescents (group 1: 85thBMI<95th percentile, n=40; group 2 (BMI95th percentile, n=39) were included. The control group(group 3) included 99 healthy adolescents. Brachial-ankle (ba) PWV and ABI were estimated with blood pressure from four extremities. Heart rate (HR), and pre-ejection period/ejection time (PEP/ET) were also estimated. BMI was calculated from individual height and weight. Linear regression analysis was performed to evaluate the correlations between BMI and PWV.
RESULTS
Blood pressure and baPWV were significantly higher in group 2, compared to either group 1 or group 3. However, there was no significant difference in ABI, HR and PEP/ET between the groups. PWV showed linear correlation with both BMI and body weight.
CONCLUSION
Obesity was associated with higher arterial stiffness in adolescents, which was demonstrated by an increase in PWV. There was no significant correlation between obesity and ABI.
