adiposity rebound
The normal increase in BMI that occurs around 5-7 years of age after the initial decline in early childhood.
Full Definition
Adiposity rebound refers to the physiological increase in body mass index (BMI) that typically occurs between 5-7 years of age, following the natural decline in BMI that begins around 1-2 years of age. This rebound represents a normal developmental milestone in body composition changes during childhood. Early adiposity rebound (occurring before age 5) is associated with increased risk of later obesity and metabolic complications. The timing of adiposity rebound is influenced by genetic factors, nutrition, and physical activity patterns. In pediatric endocrinology, monitoring adiposity rebound timing can help identify children at risk for future weight-related health problems.
Usage
Usage note: Distinguish from pathological weight gain; emphasize normal developmental nature when appropriate.
