ABSTRACT
OBJECTIVE:
We aimed to explore the risk factors that may lead to vitamin D deficiency in pregnant women living in moderately high-altitude regions.METHODS:
The study was conducted prospectively between November 2012 and July 2013. City of Erzurum is located at an altitude of 1900-2200 m, north Turkey at 39°4' latitude. Healthy mothers that gave birth after completing 37th week of their pregnancies and healthy neonates weighting >2500 g were included in the study. For 25-hydroxyvitamin D (25(OH)D) analyses venous blood samples of 2 ml were obtained from the umbilical cord and the mother. Questionnaires were developed covering the demographical characteristics and possible risk factors for mothers.RESULTS:
Totally 81 mothers and neonates were included into the study. The mean 25(OH)D level of mothers was 7.1 ± 6.5 ng/ml. It was noted that 45 (55.7%) mothers had severe deficiency. Multivariate linear regression analysis showed that the dressing style and the level of sunlight received by the house were independent factors affecting the level of 25(OH)D.CONCLUSION:
Our findings showed that cultural factors had significant effects on vitamin D levels. We believe that appropriate dose of vitamin D prophylaxis should be administered to pregnant women, considering the risk factors as well as the geographical features.Palavras-chave
