(1), “The effect of place of residence and lifestyle on vitamin D deficiency in pregnancy: Comparison of eastern and western parts of Turkey”. The authors discussed the prevalence and the predictive factors of vitamin D deficiency in pregnancy and the compliance with “The National Vitamin D Support Program” in Turkey’s easternmost and westernmost provinces. They found that clothing style, seaside holiday duration, consuming fish, living in high-altitude cold regions, and 1200 IU/day vitamin D supplementation affected vitamin D levels. They also showed that vitamin D deficiency in pregnancy is high in Turkey. They recommended increasing compliance with “The National Vitamin D Support Program” at the followup of all pregnant women.eninfo:eu-repo/semantics/openAccessLetter1542642652-s2.0-84919765118Q3163940WOS:000420676800015N/A
