Childhood obesity and central precocious puberty

Area of Science:

• Pediatric Endocrinology
• Metabolic Disorders
• Public Health

Background:

• Childhood obesity is a global health issue with a known link to central precocious puberty (CPP).
• The precise biological mechanisms connecting obesity and CPP remain unclear.
• Early puberty can lead to significant health issues in adulthood.

Purpose of the Study:

• To review current research on how childhood obesity influences the hypothalamic-pituitary-gonadal axis and pubertal timing.
• To explore the roles of key metabolic factors and signaling pathways in this association.
• To summarize strategies for preventing and treating both childhood obesity and CPP.

Main Methods:

• Literature review of recent studies on childhood obesity and central precocious puberty.
• Focus on adipokines (leptin, ghrelin), insulin, ceramides, and signaling pathways (AMPK/SIRT, mTOR).
• Analysis of the integration between peripheral metabolism and central neuroendocrine regulation.

Main Results:

• Childhood obesity impacts the hypothalamic-pituitary-gonadal axis through metabolic mediators like leptin, insulin, and ceramides.
• Signaling pathways such as AMPK/SIRT and mTOR are critical in integrating metabolic signals that influence pubertal onset.
• Obesity-related metabolic dysregulation is a key factor in the development of CPP.

Conclusions:

• Understanding the interplay between metabolic factors and neuroendocrine pathways is crucial for addressing the link between obesity and CPP.
• Preventing childhood obesity and CPP offers substantial benefits for long-term health.
• Further research and societal attention to metabolic stress in children are needed to prevent comorbidities.
