Abstract

Introduction: Preeclampsia is one of the common diseases in pregnancy and has several etiologies including seasonal changes, day-night duration and temperature changes. If there was a relationship, preventive measures are recommended in these seasons; therefore, this study was performed with aim to evaluate the effect of age and season on preeclampsia incidence.
Methods: In this descriptive-analyzing study, 264 preeclampsia cases who had been admitted in gynecology ward of Imam-Reza hospital during 3 years. Control group consisted of 10829 deliveries without any complication in these three years. The age and season of disease incidence were recorded for each group. Data was analyzed by SPSS software (version 15), and Chi-square test, Pearson correlation and ANOVA. PResults: Preeclampsia incidence rate was 2.37% in this study. Preeclampsia incidence was 12.5% in mothers 35 years, and 2.22% in mothers aged 15-35 years. There was significant difference between preeclampsia incidence at both reproductive ending and the group of 15 to 35 years (P=0.000). The highest preeclampsia prevalence was reported in March (3.55%) and the least prevalence in July (1.44%). Prevalence of preeclampsia was highest in winter (3.25%) and lowest in summer (1.64%). Significant difference was observed in preeclampsia incidence between winter and summer (P=0.000)
Conclusion: Prevalence of preeclampsia was higher in both ends of reproductive age. Preeclampsia prevalence was higher in cold seasons and lower in warm seasons
