Contributing factors to perinatal mortality among women who gave birth at the Jimma University Medical Centre, southwest Ethiopia

Perinatal mortality remains a challenge worldwide, particularly in developing countries. Although significant achievements have been made to reduce neonatal mortality worldwide, in the last two decades there was a total of 5.3 million neonatal deaths and stillbirths each year. This study aims to assess the magnitude of perinatal mortality and its contributing factors among births at the Jimma University Medical Centre in Ethiopia. A facility-based cross-sectional study was conducted between January and April 2017. Convenience sampling was used to select study participants and data were collected using interviewer-administered pretested structured questionnaires. Descriptive statistics were used to analyse the data, with the chi-square test used to assess the relationship between each factor and outcome. Statistical significance was set at P<0.05. The rate of perinatal death was 107 per 1000 births, of which 39.2%, 25.9% and 34.9% were fresh stillbirths, macerated stillbirths and early neonatal deaths respectively. The majority (77.8%) of stillbirths occurred before the study participant reached the hospital and 64.3% of stillbirths had low birth weight. Hyaline membrane disease (27.6%) and meconium aspiration syndrome (20.7%) were the two most common causes of early perinatal death. Obstetric complications contributed to 89.6% of perinatal deaths. Stillbirth was significantly associated with a lack of education (P=0.036). The rate of perinatal mortality was high among women with their first pregnancy (53.0%) and those who had no previous pregnancy-related problems (79.5%), and was significantly associated with mechanical causes and antepartum haemorrhage (P=0.015). The findings indicated that the rate of perinatal mortality was high at the Himma University Medical Centre. Improving maternal education and health services in rural areas are important steps to prevent poor perinatal outcomes. Facilitating transport and improving referral procedures may help to prevent mechanical complications, which are the most common cause of perinatal death, particularly fresh stillbirths which, in the present study, often occurred before a participant arrived at the hospital.
