There are few studies on the vitamin D status in preeclamptic women. The objective of this case-control study was to determine vitamin D status, in preeclamptic women and compare it with that of healthy pregnant controls. Forty preeclamptic women, aged 18 to 45yr and forty age- and pregnancy weight-matched healthy controls participated in the study. Serum 25-hydroxy vitamin D (25(OH)D) levels were meas­ured and its levels of <10, 10-30, 30-90 and >90 nanogram per milliliter (ng/ml) were considered as vitamin D deficiency, insufficiency, sufficiency, and toxicity, respectively. Sixty and forty percent of preeclamptic women were vitamin D deficient and insufficient, while in the control group they were 10% and 90%, respectively. No significant difference was found in the median intake of vitamin D between preeclamptic and non preeclamptic women (1.45 and 1.20µg/day respectively), but serum 25(OH)D concentration was significantly lower in preeclamptic cases compared to controls (10.09 ± 6.66 and 15.73 ± 5.85ng /ml respectively, P= 0.002). Vitamin D deficiency is common among preeclamptic and non-preeclamptic pregnant women in the north-west of Iran. Preeclampsia can cause decreasing of serum level of 25(OH)D.
