First, demographic features were obtained then, maternal serum vitamin D concentration was measured by enzyme-linked immunoassay and cervical length was measured via transvaginal sonography according to fetal maternal foundation guideline and appropriate statistical test was used to analyze the correlation between maternal vitamin D level and cervical length in mid-pregnancy.\r\nResults: It was shown that 29.6% and 25.4% of participants had vitamin D deficiency and insufficiency, respectively. Spearman\u2019s test found no significant correlation between maternal vitamin D level and cervical length in mid-pregnancy. Moreover, cervical length and maternal vitamin D level had no association with maternal BMI.\r\nConclusion: Although maternal vitamin D level and its sufficiency status was not associated with cervical length in mid- pregnancy, as a trend toward decreased maternal serum vitamin D level by advancing gestational age was observed. It may be concluded that it is prolonged vitamin D deficiency during gestation that may lead to cervical length shortening and subsequent preterm delivery later in gestation.\r\n\u00a0<\/jats:p>","DOI":"10.18502\/jfrh.v16i4.11360","type":"journal-article","created":{"date-parts":[[2022,12,13]],"date-time":"2022-12-13T02:34:55Z","timestamp":1670898895000},"source":"Crossref","is-referenced-by-count":0,"title":["Could Maternal Vitamin D Concentration Affect Cervical Length in Mid-Pregnancy?
