To determine magnitude and associated factors ofadverse perinatal outcomes oflate term and post term pregnanciesamong women who delivered inUniversity of Gondar specialized hospital, north west Ethiopia, from March to October 2021

Abstract

ABSTRACT Introduction: Postterm pregnancy is defined as a pregnancy that has reached or extend beyond 294 days or 42 weeks of gestation. Worldwide the incidence of post term pregnancy varies and ranges from 1.16% to 8.94%.Postterm pregnancy is associated with significant perinatal complications like increased perinatal mortality, oligohydramnios, meconium-stained amniotic fluid, low 5-minute APGAR Objective: The objective of this study is to determinethe magnitude and associated factors of adverse perinatal outcomes of late term and postterm pregnanciesamong women who deliveredatUniversity of Gondar specializedhospital, northwest Ethiopia, 2021. Methods:comparative cross-sectional study was conducted From March to October 2021 with sample size of 274participants whodelivered in the study period. Semistructured

questionnaire and data collection check listwas used to collect the data. Descriptive statistics will be performed to describe the characteristics of the study populations and multivariable logistic regression model was constructed to identify covariates significantly associated with the outcome variables. Statistical significance will be declared at P-value<0.05 and the AOR with 95% confidence levelwas used to determinethe strength of association. Result: The magnitude of adverse perinatal outcome is 33.9% The adverse perinatal outcome in late term pregnancy is 28.5% vii Adverse perinatal outcome in post term pregnancy39.4% Teenage pregnancy Conclusion:Adverse perinatal outcome is significantly higher in post term pregnancy as compared to late term pregnancy. There is high prevalence of MSAF and meconium aspiration which is directly associated with increased risk of perinatal morbidity and mortality. So, elective induction of labor at 41weeks of gestation may be considered to decrease complications associated with post term pregnancy.it is also higher in teenagers and district and zonal health officers should give education about reproductive health family planning. Key words: post term pregnancy, late term pregnancy, perinatal outcome, Ethiopia.
