Screening for hypovitaminosis D was performed at the time of first trimester routine scan between 11 and 13 weeks of gestations. Women were offered measurement of serum 25-hydroxyvitamin D (25[OH]D). Levels of 25(OH)D are interpreted as follows: 12 to &lt;20\u2009ng\/mL: Vitamin D insufficiency;\u2009&lt;\u200912\u2009ng\/mL: Vitamin D deficiency. Women with Vitamin D insufficiency or deficiency were offered daily oral supplementation at the dose of 2.000 UI, along with folic acid. The primary outcome was the prevalence of hypovitaminosis D in our cohort.<\/jats:p><jats:p>During the study period, between January 2023 and January 2024, 250 pregnant women were included in the study and screened for 25(OH)D. More than half of the screened women had 25(OH)D\u2009&lt;\u200920\u2009ng\/mL, with a prevalence of &lt;12\u2009ng\/mL of 14%.

The overall rate of preterm delivery before 37 weeks was 8.4%, whereas the incidence of preeclampsia was 2.8%. Rate of preterm delivery was higher in women who did not received supplementation (9.5 vs. 30.8%), but the study was not powered for such comparison.<\/jats:p><jats:p>Hypovitaminosis D has high prevalence in pregnant women.
