A relationship has been shown between vitamin D deficiency and respiratory disorders in neonates. This research was carried out to evaluate the serum level of vitamin D in TTN newborns and their mothers compared to the control group. <jats:bold>Methods<\/jats:bold>: This case-control research was conducted during 2016-2019 in a general hospital affiliated with Mashhad University of Medical Sciences, Iran. Thirty-four infants with TTN and 82 neonates in the control group as well as their mothers were investigated. The levels of umbilical cord serum vitamin D in infants with TTN and also their mothers were compared to the control group. <jats:bold>Results<\/jats:bold>: The mean levels of serum vitamin D in infants with TTN and their mothers were 8.11 \u00b1 4.32 and 12.6 \u00b1 10.12 ng\/mL, respectively (P&lt;0.001), whereas they were 19.21 \u00b1 12.71 and 25.96 \u00b1 16.6 ng\/mL in the newborns of the control group and their mothers, respectively (P&lt;0.001). The mean differences (95% CI) of neonatal and maternal vitamin D level between the two groups were 11.10 (7.92\u201314.28) and 13.36 (7.90\u201318.08), respectively. In the TTN group, 100% of the infants had vitamin D levels less than 30 ng\/mL (79.4% had severe, 17.6% had moderate and 2.9% showed mild deficiency). However, vitamin D levels lower than 30 ng\/mL were observed in 76.4% of the neonates in the control group (28.8% had severe, 31.1% showed moderate and 16.3% had a mild deficiency) (P&lt;0.001). <jats:bold>Conclusion<\/jats:bold>: The serum vitamin D levels of infants with TTN and their mothers were significantly lower than the control group. Therefore, TTN in infants may be reduced through the treatment of vitamin D deficiency in mothers.<\/jats:p>","DOI":"10.34172\/aim.2020.55","type":"journal-article","created":{"date-parts":[[2020,9,4]],"date-time":"2020-09-04T07:25:43Z","timestamp":1599204343000},"page":"530-535","update-policy":"https:\/\/doi.org\/10.34172\/crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Comparison of Umbilical Cord Serum Vitamin D Levels between Infants with Transient Tachypnea of the Newborn and those without Respiratory Distress"],"prefix":"10.34172","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4022-5426","authenticated-orcid":true,"given":"Hassan","family":"Boskabadi","sequence":"first","affiliation":[{"name":"Department of Pediatrics, Neonatal Research Centre, Faculty of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gholamali","family":"Maamouri","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Neonatal Research Centre, Faculty of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Farnaz","family":"Kalani-moghaddam","sequence":"additional","affiliation":[{"name":"Department of pediatrics, Faculty of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammad Hosein","family":"Ataee Nakhaei","sequence":"additional","affiliation":[{"name":"Department of pediatrics, Faculty of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maryam","family":"Zakerihamidi","sequence":"additional","affiliation":[{"name":"Department of Midwifery, Faculty of Medicine, Islamic Azad University, Tonekabon Branch, Tonekabon, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9000-8051","authenticated-orcid":true,"given":"Forough","family":"Rakhshanizadeh","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Faculty of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"20123","published-online":{"date-parts":[[2020,8,1]]},"container-title":["Archives of Iranian Medicine"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.aimjournal.ir\/PDF\/aim-23-530.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/www.aimjournal.ir\/PDF\/aim-23-530.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,9,4]],"date-time":"2020-09-04T07:25:44Z","timestamp":1599204344000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.aimjournal.ir\/Article\/aim-13510"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,8,1]]},"references-count":0,"journal-issue":{"issue":"8","published-online":{"date-parts":[[2020,8]]}},"URL":"https:\/\/doi.org\/10.34172\/aim.2020.55","relation":{},"ISSN":["1029-2977","1735-3947"],"issn-type":[{"value":"1029-2977","type":"print"},{"value":"1735-3947","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,8,1]]},"assertion":[{"value":"Academy of Medical Sciences of the I.R.
