Abstract :
Introduction: Evidence suggests a high prevalence of calcium and vitamin D deficiencies exists in both pregnant women and babies. Adequate intake of micronutrients has great importance especially during pregnancy and lactation period. Thus, the present study aimed at assessing the effect of vitamin D and calcium-vitamin D on pregnancy and birth outcomes (including duration of pregnancy, type of delivery and infant anthropometric indicators). Methods: A randomized, controlled, clinical, triple-blind trial conducted on 126 pregnant women referring to Tabriz health centers in 2013-14. Subjects were allocated into three groups using block randomization. Interventional groups received vitamin D, calcium-vitamin D and placebo pills daily for 60 days. ANCOVA and Chi-square tests were used for data analysis. Results: By controlling BMI before and during pregnancy, there were no significant differences between the group in average neonatal weight, height and head circumference, duration of pregnancy, type of delivery and gestational age at the time of delivery. Conclusion: The results show that calcium-vitamin D and vitamin D have no effect on duration of pregnancy, type of delivery and infant anthropometric indicators.
