Does vitamin D have a potential role in precocious puberty? A meta-analysis

Area of Science:

• Pediatric Endocrinology
• Nutritional Science
• Public Health

Background:

• Precocious puberty is a pediatric endocrine condition linked to adverse health outcomes.
• Low vitamin D levels have been anecdotally associated with precocious puberty, but evidence is conflicting.
• Understanding the role of vitamin D is crucial for managing this condition and its long-term effects.

Approach:

• A comprehensive meta-analysis was conducted, searching multiple databases up to October 2022.
• Evaluated vitamin D concentrations in precocious puberty patients versus controls.
• Assessed the risk of precocious puberty associated with low vitamin D and the impact of vitamin D supplementation in patients undergoing treatment.

Key Points:

• Children with precocious puberty exhibit significantly lower serum vitamin D levels compared to healthy peers.
• Low vitamin D levels increase the risk of developing precocious puberty.
• Combined treatment with gonadotropin-releasing hormone analogue (GnRHa) and vitamin D improved hormonal profiles, reduced bone age, and increased predicted adult height compared to GnRHa alone.

Conclusions:

• Vitamin D may play a significant role in the development and management of precocious puberty.
• Further large-scale clinical trials are warranted to validate these findings and establish definitive treatment guidelines.
• This research highlights vitamin D as a potential therapeutic target for precocious puberty.
