Exploring the Multivariate Association Between Physical Fitness and Cardiometabolic Risk in Children and Adolescents

Area of Science:

• Pediatric Health
• Cardiovascular Research
• Exercise Science

Background:

• Childhood obesity and cardiometabolic risk are growing public health concerns.
• Understanding the interplay between physical fitness, adiposity, and cardiometabolic health in youth is crucial for prevention strategies.

Purpose of the Study:

• To investigate the multivariate associations between physical fitness components and adiposity with cardiometabolic risk in children and adolescents.
• To identify which fitness markers remain associated with cardiometabolic risk after accounting for adiposity.

Main Methods:

• Cross-sectional study of 6405 participants aged 6-18 years.
• Assessed waist circumference, skinfolds, and various physical fitness measures (e.g., cardiorespiratory fitness, agility).
• Calculated a continuous cardiometabolic risk score (cMetS) and used multivariate pattern analysis across three models.

Main Results:

• Inverse associations with cMetS were observed for several fitness components, particularly cardiorespiratory fitness and agility.
• Cardiorespiratory fitness demonstrated a consistent adiposity-independent association with lower cardiometabolic risk in both males and females.
• Agility also showed an adiposity-independent association with cardiometabolic risk, primarily in males.

Conclusions:

• Cardiorespiratory fitness is the most significant adiposity-independent predictor of cardiometabolic health in youth.
• Agility emerges as another relevant fitness marker associated with cardiometabolic risk.
• These findings underscore the importance of promoting cardiorespiratory fitness and agility for preventing cardiometabolic diseases in children and adolescents.
