Abstract

Objective: To investigate the predictors of preeclampsia based on a 10-years case-control study.

Materials and methods: The present retrospective, case-control study was carried out in a referral Hospital in Hamadan, Iran, during 2005-2015. Using a hospital information system (HIS), all the available information on hospitalized preeclamptic patients during 10-years period was collected and all preeclamptic women were qualified for the study as the case group (729 subjects) and the same number of non-preeclamptic women were assigned to the control group. The required data were collected using the researcher-made questionnaire and analyzed using descriptive statistics, chi-square test, independent t-test and logistic regression.

Results: The results show that high age (OR = 1.04), low education (diploma compared to illiterate
OR = 0.51 and middle school education compared to illiterate OR = 0.55), blood group O (AB: OR = 0.32; B: OR = 0.36; A: OR = 0.26) and fertilization during autumn (spring: OR = 0.41; summer: OR = 0.26; autumn: OR = 1.13) could raise the risk of preeclampsia.

Conclusion: High age, low education, blood group O and fertilization in cold seasons could be the risk factors of preeclampsia. Recognizing the risk factors of preeclampsia could help the determination of high risk cases and designing of effective interventions.
