Abstract

Introduction: Hypertensive disorders in pregnancy lead to serious complications such as bleeding and infection that is associated with increased mortality. This study was performed with the aim of evaluating the association between seasonal patterns and preeclampsia
Methods: This case-control study was performed on 455 pregnant women (205 with preeclampsia and 250 without preeclampsia) who had referred to the maternity of Amol Imam Ali hospital after 20 weeks of gestation from 2008-2013. Data such as demographic characteristics and history of mothers' disease were collected from medical records on file available in the hospital. Data analysis was performed with SPSS software (version 20) and Chi-square, Fisher's exact, Mann–Whitney U tests, simple and multiple logistic regression. PResults: the highest incidence of preeclampsia was in the fall (31.21%) and then in the winter (28.78%). Chi-square test results showed that there was significant relationship between preeclampsia and the history of abortion, diabetes, hypertension and twin pregnancy (P<0.05). Also, Mann–Whitney U results showed that the mean maternal age was 28.61±6.00 years, gestational age 35.75±3.50, and birth weight 2600.73±841.28 in mothers with preeclampsia which were significantly different with healthy women.(p<0/05)
Conclusion: Understanding the relationship between different weather patterns and preeclampsia can be useful in identifying triggers of the risk of preeclampsia. Also, the results of this study can help to design the plans to perform preventive and treatment measures in susceptible pregnant women and decrease serious complications which threaten the mother and fetus.
