Miscarriage is the most common complication of pregnancy. Moreover, vitamin D deficiency is a prevalent concern among women of reproductive age, particularly in the Arab world, where the link between vitamin D deficiency and miscarriage is still unknown. This study was conducted to determine the relationship between vitamin D and miscarriage by comparing the concentration of vitamin D among women with spontaneous abortion and pregnant women. A total of 80 subjects were enrolled in this study and divided into two groups. The first group included 40 women with spontaneous abortions aged between 18 and 40 years. The second group included 40 pregnant women without previous history of miscarriages. Total 25-hydroxy vitamin D (25-OH-VD) measurement was estimated with a Dry Fluorescence Immunoassay analyzer using the Lansionbio LS-1100 instrument. The relationship between the five age groups and the vitamin D status of women with spontaneous abortion was not significant (p>0.05). There was no significant relationship between the miscarriage trimesters and vitamin D status (p>0.05) and between the five age groups (p>0.05). In our study, 95% of women with spontaneous abortion had vitamin D deficiency, compared to only 17.5% of pregnant women. A normal range of vitamin D improves the growth of the fetus and prevents pregnancy complications and miscarriage, promoting the growth of blood vessels in the placenta and improving the function of immune cells.
