A family-based multicomponent lifestyle modification intervention with the goal to increase the consumption of fruits and vegetables and and meet physical activity recommendations.

Measure of insulin in the blood after fasting.

Measure of blood sugar (glucose) after fasting.

Nuclear magnetic resonance (NMR) measures of lipoprotein (low-density lipoprotein [LDL], high-density lipoprotein [HDL], very-low density lipoprotein [VLDL]) particle number and size will be assessed.

PWA will be assessed by a central aortic pressure waveform synthesized from the measured brachial artery pressure waveform via a standard blood pressure cuff inflation/deflation and blood pressure monitoring.

Carotid-to-femoral PWV will be measured by simultaneously recording electrocardiography (ECG) and a carotid or femoral pressure waveform via a standard blood pressure cuff inflation/deflation and blood pressure monitoring. The distance from the carotid measurement point to the sternal notch will be subtracted from the distance from the sternal notch to the femoral measurement point and used as propagation distance. PWV will be calculated as propagation distance/time delay. PWV is a measure of regional stiffness of the aorta.

The FMD technique will be employed by assessing the diameter and blood flow velocity of the artery located in the upper arm via ultrasonography. FMD will be used as a measure of endothelial-dependent vessel function and will be expressed as a percent change from baseline, normalized for shear rate calculated from blood flow velocity and vessel diameter data.
