Clinical longitudinal standards for height and height velocity for North American children

Area of Science:

• Pediatric endocrinology
• Growth and development studies

Background:

• Accurate growth assessment is crucial for monitoring child development.
• Existing growth charts may not adequately represent diverse maturation patterns.

Purpose of the Study:

• To present new longitudinally-based height and height velocity charts for North American children.
• To provide centiles for different maturation timings (early, middle, late).

Main Methods:

• Utilized a review of longitudinal growth studies to define curve shapes.
• Incorporated National Center for Health Statistics data for prepubertal and adult height centiles.
• Developed charts applicable across the entire growth period, including puberty.

Main Results:

• Longitudinally-based height and height velocity centile charts are provided.
• Charts differentiate between early, middle, and late maturing children.
• The charts are designed for tracking individual growth trajectories.

Conclusions:

• These charts offer a valuable tool for pediatricians and researchers.
• They facilitate precise monitoring of growth and response to interventions.
• The charts support individualized assessment of child development in North America.
