Insolation effect on vitamin D supply in children during sanatorium treatment

Area of Science:

• Pediatrics
• Nutritional Science
• Environmental Health

Background:

• Vitamin D is crucial for children's health.
• Sunlight exposure is a primary source of Vitamin D.
• Sanatorium stays can influence children's environmental exposure.

Purpose of the Study:

• To assess serum 25-hydroxyvitamin D3 levels in children aged 5-7 years.
• To correlate vitamin D levels with isolation conditions and solar radiation.
• To evaluate vitamin D sufficiency during a specific period in a sanatorium setting.

Main Methods:

• Serum 25-hydroxyvitamin D3 (25/OH/D3) levels were measured.
• Data collected from 58 children aged 5-7 years.
• Study conducted in Kołobrzeg from April 1 to September 30, 1981.

Main Results:

• Sufficient vitamin D supply was observed only from June to September.
• No correlation between solar radiation and vitamin D levels in other months.
• Exogenous vitamin D administration was discontinued prior to and during the study.

Conclusions:

• Seasonal variations significantly impact vitamin D levels in children.
• Solar radiation alone may not guarantee adequate vitamin D levels.
• Further research is needed on vitamin D supplementation strategies for children in institutional settings.
