A Proposed Pediatric Clinical Cardiovascular Health Reference Standard

Area of Science:

• Pediatric cardiovascular health research
• Biostatistics and epidemiology
• Public health

Background:

• Clinical cardiovascular health (CVH) in adults integrates four factors: blood pressure, fasting glucose, total cholesterol, and body mass index (BMI).
• A similar comprehensive metric for assessing pediatric cardiovascular health is currently lacking.
• Early identification of cardiovascular risk factors in childhood is crucial for long-term health outcomes.

Purpose of the Study:

• To develop sex-specific, age-based reference charts for clinical cardiovascular health in children and adolescents.
• To provide a standardized tool for assessing pediatric cardiovascular health.
• To facilitate early intervention and lifelong cardiovascular health optimization.

Main Methods:

• Utilized data from six pooled childhood cohorts (19,261 participants, aged 8-19 years, 1972-2010).
• Developed reference standards for fasting glucose and total cholesterol using sex-specific random-effects linear regression models.
• Integrated glucose and cholesterol models with existing reference standards for BMI and blood pressure to create comprehensive CVH charts.

Main Results:

• Generated sex-specific charts displaying smoothed means, percentiles, and standard deviations of CVH for each year of childhood.
• Demonstrated an example calculation of a composite CVH percentile for a 10-year-old girl.
• Established a method to express pediatric CVH as an age- and sex-standardized percentile.

Conclusions:

• Pediatric clinical cardiovascular health charts provide a standardized method for assessing cardiovascular health in children.
• These charts enable clinicians to identify cardiovascular risk and implement preventive strategies from an early age.
• Proactive assessment and intervention in childhood can optimize lifetime cardiovascular health trajectories.
