Cardiometabolic Risk Variables in Preadolescent Children: A Factor Analysis

Area of Science:

• Pediatric cardiology
• Cardiovascular health
• Metabolic health

Background:

• Atherosclerosis accelerates in preadolescence due to poor lifestyle behaviors.
• Cardiometabolic risk factors cluster, but studies often overlook preadolescents or specific measures.
• Novel inclusion of glycated hemoglobin and central hemodynamic measures in pediatric research.

Purpose of the Study:

• To investigate the underlying factors of cardiometabolic health in preadolescent children.
• To identify distinct components of cardiometabolic risk in this age group.
• To differentiate the roles of glycated hemoglobin and fasting blood glucose in glycemic control.

Main Methods:

• Cross-sectional study of 392 New Zealand children (9.5 years old, 50% girls).
• Principal component analysis applied to various cardiometabolic risk variables.
• Inclusion of central systolic blood pressure, augmentation index, glycated hemoglobin, and fasting blood glucose.

Main Results:

• Four factors explained 60% of the variance: blood pressure, adiposity, lipids, and vascular.
• Blood pressure included central and peripheral measures.
• Adiposity comprised waist circumference, BMI, and glycated hemoglobin; lipids included cholesterol fractions; vascular included augmentation index, heart rate, and fasting blood glucose.

Conclusions:

• A single factor does not define cardiometabolic health in preadolescents.
• Identified factors align with adolescent findings, with vascular factors primarily driven by augmentation index.
• Glycated hemoglobin and fasting blood glucose load separately, indicating distinct roles in chronic versus short-term glycemic control.
