Objective: We aimed to reveal the prevalences of vitamin D deficiency and severe deficiency in pregnant women who applied for routine examination in our study. Material and Methods: Between January 2015 and January 2018, 635 healthy pregnant women who applied to our clinic for the first trimester routine pregnancy examination were included in the study. The age, place of residence, season in which the material was taken, 25 - OH vitamin D levels were reached. Vitamin D level under 10 ng/ml was accepted as severe deficiency, 10 - 30 ng/ml insufficiency and 30 - 100 ng/ml normal. Results: Vitamin D deficiency was detected in 58.1 % and severe deficiency was found in 36.9 %, while vitamin D levels were normal in only 5 % of the patients. Vitamin D levels were significantly lower in the 35 years old group (95.8 % - 90.9 %) (p = 0.03). There was no statistical correlation between the place of residence and vitamin D (94.6 % - 95.7 %) (p = 0.529). We found abnormal vitamin D results in winter and autumn season (98 % - 99.4 % versus 89.4 % - 93.3 %) (p = 0,000). Conclusion: We observed that vitamin D deficiency and severe deficiency, which have serious maternal and neonatal effects, are quite common in our society (95 %). We are in the belief that how much decrease in negative maternal and perinatal outcomes have been observed with the ‘Vitamin D Supplement Programme in Pregnancy’ hold by T.C. Ministry of Health, via using 1200 IU vitamin D perday from 12 week of pregnancy until postpartum 6th month, by cross-sectional studies and if the first 6 year results are in positive direction, deficiency must be replaced according to age, season, and the geographic region with more effective methods.
