Serum levels of Vitamin A and Atopic Rhinoconjunctivitis in Swedish adolescents
Aim : Vitamin A plays a role in mucosal immunity and tolerance, but the association between vitamin A status and allergy is still unclear. The aim of the study was to analyze the levels of vitamin A in serum from adolescents with or without atopic rhinoconjunctivitis. Method : Thirteen-year-old chil...

The aim of the study was to analyze the levels of vitamin A in serum from adolescents with or without atopic rhinoconjunctivitis. Method : Thirteen-year-old children with atopic rhinoconjunctivitis (n = 53) and non-allergic, nonsensitized controls (n = 52) were randomly selected from a population based prospective birth cohort comprising 1228 children in Northern Sweden born in 1996-1997.

Results : Multiple logistic regression analysis showed no association between serum vitamin A levels and atopic rhinoconjunctivitis prevalence; OR = 1.00 (95% confidence interval 1.00-1.00), p = 0.81.

Conclusions : Serum levels of vitamin A could neither be positively nor negatively associated with atopic rhinoconjunctivitis in Swedish teenagers.
