Determinants of serum vitamin D levels in preadolescent cystic fibrosis children.
The effects of liver disease, fat malabsorption and sunlight exposure on serum vitamin D levels were determined in 21 optimally treated preadolescent cystic fibrosis (CF) children over a 12-month period. Manifest liver disease and fat malabsorption appeared not to affect the vitamin D level. However, the level fell significantly in winter, although not below the normal range, suggesting that sunlight exposure is a more important determinant of vitamin D levels in preadolescent CF children than liver disease and fat malabsorption.
