Through a cross-sectional study, 79 patients with FA, from ages 2 to 15 years, were assessed and followed up in a reference out-patient clinic, in Sao Paulo, Brazil. Clinical and biochemical data were collected for analysis of 25(OH)D, calcium, phosphorus, phosphatase, parathyroid hormone (PTH), and high-sensitivity C-reactive protein (hs-CRP). The cut-off point used for vitamin D deficiency was 25(OH)D \u2264 20 ng\/mL. Vitamin D deficiency was detected in 45.6% of patients with a median age of 6.9 years (Interquartile range [IQR] 4.7; 10.2). The median serum 25(OH)D concentration was 21.1 ng\/ mL (IQR 17.8; 26.0). Multivariate linear regression was performed considering serum vitamin D level as a dependent variable. Allergy to multiple foods (inverse) and length of sun exposure (direct), but not nutritional status, were independently associated with serum 25(OH)D levels (P = 0.034 and P = 0.014, respectively). Patients with cow\u2019s milk allergy also showed lower vitamin D concentrations in comparison with other FA (19.1 ng\/mL [IQR 16.6; 24.4] vs 22.2 ng\/mL [IQR 18.1; 27.1] [P = 0.056]). Vitamin D deficiency affected about half of individuals with FA. Multiple food allergy was associated with lower vitamin D concentrations, reinforcing the importance of monitoring vitamin D status in patients with FA.<\/jats:p>","DOI":"10.15586\/aei.v50i6.571","type":"journal-article","created":{"date-parts":[[2022,11,1]],"date-time":"2022-11-01T17:44:23Z","timestamp":1667324663000},"page":"10-16","source":"Crossref","is-referenced-by-count":9,"title":["Vitamin D deficiency in children and adolescents with food allergy"],"prefix":"10.15586","volume":"50","author":[{"given":"Andressa","family":"Pereira","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Raquel","family":"Mendon\u00e7a","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fernando","family":"Fonseca","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M\u00e1rcia","family":"Mallozi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roseli","family":"Sarni","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"6228","published-online":{"date-parts":[[2022,11,1]]},"container-title":["Allergologia et Immunopathologia"],"original-title":[],"link":[{"URL":"https:\/\/all-imm.com\/index.php\/aei\/article\/download\/571\/1010","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/all-imm.com\/index.php\/aei\/article\/download\/571\/1011","content-type":"text\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/all-imm.com\/index.php\/aei\/article\/download\/571\/1012","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/all-imm.com\/index.php\/aei\/article\/download\/571\/1010","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,11,2]],"date-time":"2022-11-02T17:43:59Z","timestamp":1667411039000},"score":1,"resource":{"primary":{"URL":"https:\/\/all-imm.com\/index.php\/aei\/article\/view\/571"}},"subtitle":["Association with number of allergens, sun exposure and nutritional status"],"short-title":[],"issued":{"date-parts":[[2022,11,1]]},"references-count":0,"journal-issue":{"issue":"6","published-online":{"date-parts":[[2022,11,1]]}},"URL":"https:\/\/doi.org\/10.15586\/aei.v50i6.571","relation":{},"ISSN":["0301-0546"],"issn-type":[{"value":"0301-0546","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,11,1]]}}}
