Introduction: Pre-eclampsia (PE) is a public health problem especially in developing countries due to its incidence and severity. It is responsible for high maternal and perinatal morbidity and mortality. Accordingly, the objective of this work was to study the factors associated with the occurrence of maternal and perinatal complications of preeclampsia. Method: This was an analytical cross-sectional study with prospective and retrospective data collection including all patients, pregnant or postpartum, admitted for preeclampsia to the maternity ward of the Yaoundé Central Hospital. It took place over a period of seven (07) months. The data collected was analyzed using CS Pro 7.4, SPSS 20.0 and Microsoft Office Excel 2010 software. We compared the group with complications to the group without complications. We calculated the odds ratio to look for associations between variables and their 95% confidence intervals. The threshold for statistical significance was set at p < 0.05. Results: We recruited 214 cases of preeclampsia in our series. There were maternal complications in 44.4% of cases, dominated by eclampsia (31.8%). We recorded 07 maternal deaths, representing a maternal lethality of 3.3%. We had at least one perinatal complication in 105 cases (49.1%). The predominant perinatal complication was prematurity. We recorded 32 cases of intrauterine fetal demise and 13 cases of early neonatal death, giving
