Children and Adolescent Obesity Associates with Pressure-Dependent and Age-Related Increase in Carotid and Femoral Arteries’ Stiffness and Not in Brachial Artery, Indicative of Nonintrinsic Arterial Wall Alteration

Table 3

Correlation analysis between stiffness parameters and blood pressure levels.

	Normal weight				Obesity				(slope differences)

Right common carotid artery distensibility		0.437	<0.001	−4		0.496	<0.001	−5	0.672
Left common femoral artery distensibility		0.467	<0.001	−2		0.518	<0.001	−1	0.502
Right common femoral artery distensibility		0.448	<0.001	1		0.399	<0.001	−1	0.700
Carotid-femoral pulse wave velocity		0.398	<0.001	0.016–0.042		0.433	<0.001	0.013–0.039	0.744
Carotid-radial pulse wave velocity		0.318	<0.001	0.015–0.040		0.359	<0.001	0.011–0.035	0.756

Analysis between arterial stiffness parameters (-axis) and systolic blood pressure levels (-axis). CI: confidence interval. All regressions reached statistical significance (). There were no differences in the slopes (model comparison) between normal weight and obese children. A was accepted as statistically significant.
