The second stage includes the incidence of clinical symptoms. one of the causes of its incidence is vitamin D deficiency. This study was performed with the aim to evaluate the relationship between serum level of vitamin D and preeclampsia in pregnant women.
Methods: This case - control study was done on 50 pregnant women with severe preeclampsia and gestational age below 34 weeks and 100 non-preeclampsia pregnant women to delivery department of Besat Hospital in 2011.Data collection tool in this study was a questionnaire that was designed based on the variables. Blood sample was taken from all the research units to measure level of vitamin D. Maternal serum levels of 25-hydroxyvitamin D was measured by radio immunoassay method. in the laboratory. Data analysis was performed using SPSS software (version 18), Chi-square, Fisher exact, Independent t, and Kolmogorov-Smirnov tests.
Results: Vitamin D deficiency was observed in 80% of cases and 75% of controls. The mean of 25-hydroxyvitamin D in the case group was 11.0 ± 9.4 (ml / ng) and in control group was 16.3 ± 10.0, which had statistically significant difference (p=0.003).
Conclusion: vitamin D level of most pregnant women was lower than normal. According to the findings of this study, D deficiency can be considered as a risk factor for preeclampsia. Although, more cohort studies are needed to confirm this.
