In the present study, we aimed to determine the prevalence of vitamin D deficiency in neonates hospitalized in an intensive care unit (NICU) and its association with clinical neonatal outcomes.\r\nMaterials and methods: A prospective cross-sectional study was carried out on all neonates hospitalized in the NICU of Children's Medical Center over a period of one year (January\u2013December 2018). Immediately on admission, a serum sample for vitamin D measurement was obtained with another routine blood sampling. Demographic and clinical data including sex, gestational age, the season of birth, serum levels of vitamin D and calcium, the causes of hospitalization, age at admission and neonatal outcomes including length of hospital stay and mortality during hospitalization were assessed.\r\nResults: One hundred neonates entered the study. Vitamin D deficiency and insufficiency were present in 95% of neonates. There was a significant association between vitamin D status and birth during winter (p=0.014); hypocalcemia (p=0.025) and older age at NICU admission (p&lt;0.001). The mean value of vitamin D in term neonates was significantly lower than in preterm neonates (p=0.031). There were no correlations between length of hospital stay and neonatal mortality rate with vitamin D status (p=0.876).\r\nConclusion: Vitamin D deficiency and insufficiency were highly prevalent among NICU patients. Maternal vitamin D supplementation during pregnancy may prevent or reduce the risk of low levels of vitamin D in neonates.<\/jats:p>","DOI":"10.18502\/jfrh.v15i2.6450","type":"journal-article","created":{"date-parts":[[2021,6,16]],"date-time":"2021-06-16T08:29:01Z","timestamp":1623832141000},"source":"Crossref","is-referenced-by-count":9,"title":["Serum Vitamin D Deficiency in NICU Hospitalized Neonates and Its Association with Neonatal Outcomes"],"prefix":"10.18502","author":[{"given":"Ziba","family":"Mosayebi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Setareh","family":"Sagheb","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mahsa","family":"Mirzendedel","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amir Hossein","family":"Movahedian","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"7770","published-online":{"date-parts":[[2021,6,16]]},"container-title":["Journal of Family and Reproductive Health"],"original-title":[],"link":[{"URL":"https:\/\/publish.kne-publishing.com\/index.php\/JFRH\/article\/download\/6450\/6202","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/publish.kne-publishing.com\/index.php\/JFRH\/article\/download\/6450\/6202","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,10,5]],"date-time":"2026-10-05T12:06:54Z","timestamp":1791202014000},"score":1,"resource":{"primary":{"URL":"https:\/\/publish.kne-publishing.com\/index.php\/JFRH\/article\/view\/6450"},"secondary":[{"URL":"https:\/\/jfrh.tums.ac.ir\/index.php\/jfrh\/article\/view\/1600","label":"UNIVERSITY"},{"URL":"https:\/\/publish.kne-publishing.com\/index.php\/JFRH\/article\/view\/6450","label":"PUBLISHER"}]},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,6,16]]},"references-count":0,"URL":"https:\/\/doi.org\/10.18502\/jfrh.v15i2.6450","relation":{"has-preprint":[{"id-type":"doi","id":"10.21203\/rs.3.rs-33326\/v1","asserted-by":"object"}]},"ISSN":["1735-9392","1735-8949"],"issn-type":[{"value":"1735-9392","type":"electronic"},{"value":"1735-8949","type":"print"}],"subject":[],"published":{"date-parts":[[2021,6,16]]}}}
