Relationship between newborn craniotabes and vitamin D status

Area of Science:

• Neonatal Health
• Nutritional Biochemistry
• Pediatric Endocrinology

Background:

• Maternal vitamin D deficiency during pregnancy and infancy is linked to chronic childhood diseases.
• Craniotabes, a skull condition in newborns, has been an area of interest regarding its physiological basis and potential links to nutritional deficiencies.
• Understanding craniotabes is crucial for identifying potential health risks in newborns.

Purpose of the Study:

• To determine if craniotabes in healthy newborns is a physiological condition.
• To investigate the association between craniotabes and vitamin D deficiency in newborns and their mothers.
• To assess whether craniotabes requires specific treatment.

Main Methods:

• 150 healthy newborns (birth weight >2000g) were assessed for craniotabes.
• Newborns were categorized into groups with and without craniotabes.
• Maternal 25-hydroxyvitamin D levels were measured; infant serum calcium, phosphorus, alkaline phosphatase, parathyroid hormone, 25(OH) vitamin D, and urine calcium/creatinine were analyzed.

Main Results:

• Craniotabes was observed in 30% of newborns, with a higher incidence in winter births.
• Infants with craniotabes showed significantly higher parathyroid hormone (PTH) levels.
• Lower vitamin D levels were noted in exclusively breastfed infants, but no significant difference in craniotabes occurrence was found with or without vitamin D supplementation.

Conclusions:

• The direct link between newborn craniotabes and maternal vitamin D deficiency remains unclear.
• Maternal vitamin D deficiency is a persistent issue requiring attention.
• Enhanced strategies for preventing maternal vitamin D deficiency are essential.
