Magnitude of adverse birth outcomes and associated factors of twin pregnancy among pregnant mothers attending at Gondar university comprehensive specialized hospital, Northwest Ethiopia, 2022

Abstract

Abstract Introduction: Twin pregnancies are recognized as high risk pregnancy. Similarly twin pregnancies account for 2 to 4% of the total number of births. Worldwide the number of twin gestations has increased dramatically over the past few decades due to the expansion of assisted reproductive technology and increase in maternal age at conception. It is associated with increased incidence of adverse pregnancy outcomes and risk for neonatal morbidity and mortality. Despite this, there is a paucity of data on the magnitude and associated factors of twin pregnancy. Therefore the aim of this study is to assess the magnitude and associated factors of adverse birth outcomes of twin pregnancy among pregnant mothers attending at Gondar university comprehensive specialized hospital, Northwest Ethiopia from Jan 2016 to Dec 2021. Methods: An institution based cross-sectional study was employed. Data about adverse birth outcomes was collected from mother抯 charts using a structured data extraction sheet. A total of 305 twin deliveries were selected by using systematic random sampling. Bi-variable and multivariable analyses were performed. The results were considered significant at p-value<0.05. Adjusted odds ratio and 95% CI were computed to identify associated factors and determine the strength of association. Results: the overall magnitude of adverse birth outcome was 63.9% Conclusion and recommendations: Twin pregnancy was associated with significantly higher rates of adverse birth outcomes. Among the factors, rural residence, primiparity, having no antenatal care and pregnancy induce hypertension in the current pregnancy are important factors contributing for the adverse birth outcomes. Therefore, it is better to improve the ANC coverage and early detection and treatment of hypertensive disorders of pregnancy. Key words: Birth outcome, Twin pregnancy, Ethiopia, Mother
