Background: Previous research supports a possible link between low vitamin D levels and atopic disease. However, the association between low vitamin D levels and total and allergen-specific IgE levels has not been studied. Objective: We sought to test the association between serum 25-hydroxyvitamin D (25[OH] D) deficiency (<15 ng/mL) and insufficiency (15-29 ng/mL) and allergic sensitization measured by serum IgE levels in a US nationally representative sample of 3136 children and adolescents and 3454 adults in the National Health and Nutrition Examination Survey 2005-2006. Methods: The association of 25(OH) D deficiency with 17 different allergens was assessed after adjustment for potential confounders, including age; sex; race/ethnicity; obesity, low socioeconomic status; frequency of milk intake; daily hours spent watching television, playing videogames, or using a computer; serum cotinine levels; and vitamin D supplement use. Results: In children and adolescents allergic sensitization to 11 of 17 allergens was more common in those with 25(OH) D deficiency. Compared with sufficient vitamin D levels of greater than 30 ng/mL, after multivariate adjustment, 25(OH) D levels of less than 15 ng/mL were associated with peanut (odds ratio [OR], 2.39; 95% CI, 1.29-4.45), ragweed (OR, 1.83; 95% CI, 1.20-2.80), and oak (OR, 4.75; 95% CI, 1.53-4.94) allergies (P < .01 for all). Eight other allergens were associated with 25 (OH) D deficiency, with P values of less than .05 but greater than .01. There were no consistent associations seen between 25(OH) D levels and allergic sensitization in adults. Conclusion: Vitamin D deficiency is associated with higher levels of IgE sensitization in children and adolescents. Further research is needed to confirm these findings.
