The Association of Accelerated Early Growth, Timing of Puberty, and Metabolic Consequences in Children

Area of Science:

• Pediatric Endocrinology
• Metabolic Health
• Developmental Biology

Background:

• Children born small for gestational age (SGA) exhibit higher risks for metabolic syndrome, type 2 diabetes, insulin resistance, and cardiovascular diseases, particularly with accelerated early growth.
• Premature adrenarche (PA) is also linked to metabolic disturbances and earlier pubertal timing.
• Early pubertal timing in both SGA and PA populations is associated with increased metabolic risks, necessitating further investigation.

Approach:

• This review synthesizes recent research on the relationship between early infantile growth patterns and pubertal timing.
• It examines the association between these developmental factors and the subsequent risk of metabolic syndrome.
• The review aims to elucidate the underlying pathophysiology connecting early growth, puberty, and metabolic health.

Key Points:

• Accelerated early growth and early puberty are identified risk factors for metabolic syndrome.
• SGA children, especially those with catch-up growth, are at higher long-term metabolic risk.
• Early pubertal timing in SGA and PA children correlates with various metabolic risks.

Conclusions:

• Understanding the interplay between early growth, pubertal timing, and metabolic health is crucial for identifying at-risk children.
• Further research into the pathophysiology can inform preventative strategies for metabolic syndrome in vulnerable pediatric populations.
• This review highlights the need for continued investigation into the long-term metabolic consequences of early developmental trajectories.
