Key result
Childhood obesity, high BMI, large waist circumference, and adverse lipid profiles were significantly correlated with increased arterial stiffness measured by pulse wave velocity.
Why the study?
Childhood obesity accelerates arterial stiffness and increases arterial pressure, prompting investigation into pulse wave analysis as a measure of vascular wall impairment in obese children.
Does pulse wave analysis (PWA) identify vascular wall impairment and correlate with metabolic risk factors in obese children?
Observational (n=60)
Does pulse wave analysis (PWA) identify vascular wall impairment and correlate with metabolic risk factors in obese children?
Pulse wave analysis is a useful non-invasive tool to assess vascular health and arterial stiffness in obese children, correlating well with metabolic risk factors.
May support PWA for vascular assessment in obese children; leaves open outcome prediction and intervention effects.
Childhood obesity speeds up the development of arterial stiffness and progressively increases the values of arterial pressure. The purpose of this study is to investigate the value of using pulse wave analysis (PWA) to measure arterial stiffness as a sign of vascular wall impairment in obese children. The research was focused on 60 subjects: 33 obese and 27 normal-weight. Ages ranged from 6 to 18 years old. PWA includes parameters such as pulse wave velocity (PWV), augmentation index (AIx), peripheral and central blood pressure (SBP, DBP, cSBP, cDBP), heart rate, and central pulse pressure (cPP). The device used was a Mobil-O-Graph. Blood parameters were taken from the subject's medical history, not older than 6 months. A high BMI and a large waist circumference are linked to a high PWV. The levels of LDL-c, triglycerides (TG), non-HDL-c, TG/HDL-c ratio, and total cholesterol-HDL-c ratio significantly correlate to PWV, SBP, and cSBP. Alanine aminotransferase is a reliable predictor of PWV, AIx, SBP, DBP, and cDBP, while aspartate aminotransferase is a significant predictor of AIx, mean arterial pressure (MAP), cSBP, and cPP. 25-OH-Vitamin D negatively correlates with PWV, SBP, and MAP and significantly predicts the MAP. Cortisol and TSH levels are not significant to arterial stiffness in obese children without specific comorbidities and neither is fasting glucose in obese children without impaired glucose tolerance. We conclude that PWA contributes valuable data regarding patients' vascular health and should be considered a reliable tool in the management of obese children.

Mihuţa et al. (2023) conducted an observational in Childhood obesity (n=60). Childhood obesity vs. Normal-weight was evaluated on Arterial stiffness parameters (PWV, AIx, SBP, DBP, cSBP, cDBP, heart rate, cPP). Childhood obesity, high BMI, large waist circumference, and adverse lipid profiles were significantly correlated with increased arterial stiffness measured by pulse wave velocity.
