Does Vitamin D Deficiency Contribute to Growing Pains? A Case-Control Study

Area of Science:

• Pediatrics
• Nutritional Science
• Musculoskeletal Health

Background:

• Growing pains (GPs) are common, non-inflammatory musculoskeletal pain syndromes in children aged 4-14 years.
• The potential link between vitamin D deficiency and the development of GPs remains an area of investigation.
• Understanding contributing factors to GPs is crucial for effective management and parental guidance.

Purpose of the Study:

• To investigate the association between vitamin D deficiency and the incidence of growing pains in children.
• To evaluate the effect of vitamin D supplementation on pain reduction in children diagnosed with GPs.
• To compare vitamin D levels and related biochemical markers between children with and without GPs.

Main Methods:

• A 6-month case-control study involving children aged 4-14 years with and without a history of GPs.
• Measurement of serum 25-hydroxyvitamin D (25-OHD), calcium, phosphate, and alkaline phosphatase levels.
• Administration of vitamin D3 supplementation to participants with deficient or insufficient 25-OHD levels.

Main Results:

• High prevalence of insufficient or deficient 25-OHD levels observed in both the GP group (95.6%) and the control group (93.3%).
• No significant correlations were found between serum calcium, phosphate, alkaline phosphatase, and 25-OHD levels in either group.
• Children with sufficient 25-OHD levels experienced pain reduction comparable to those receiving vitamin D supplementation.

Conclusions:

• The study found no significant difference in vitamin D levels between children experiencing growing pains and healthy controls.
• Vitamin D deficiency is highly prevalent in both groups, suggesting it may not be a primary causative factor for GPs.
• Current findings do not support vitamin D supplementation as a targeted intervention for reducing growing pains in children.
