Demographic factors including gestational age, birth weight, gender, delivery mode, parity, vitamin D supplementation during pregnancy and severity of TTN were recorded. <b><i>Results:<\/i><\/b> The serum levels of 25(OH)D<sub>3<\/sub> were significantly lower in infants with TTN compared to infants with no respiratory distress (p < 0.01). There was no statistically significant difference in serum Ca, P and ALP levels between the groups while the serum levels of PTH were significantly higher in the study group (p < 0.01). No correlation was found between the serum 25(OH)D<sub>3<\/sub> levels and severity of TTN. Vitamin D supplementation (400 IU\/day) during pregnancy did not affect the serum levels of newborns. <b><i>Conclusion:<\/i><\/b> Our data suggests that lower 25(OH)D<sub>3<\/sub> serum levels are associated with an increased risk of TTN and vitamin D may have a role in the pathogenesis of TTN.<\/jats:p>","DOI":"10.1159\/000358521","type":"journal-article","created":{"date-parts":[[2014,5,14]],"date-time":"2014-05-14T06:42:50Z","timestamp":1400049770000},"page":"397-401","source":"Crossref","is-referenced-by-count":7,"title":["Association
