Background: Congenital anomalies, affect millions of babies worldwide with a prevalence ofrn3% and it is estimated that, globally, 303,000 newborns die within the first 4 weeks of life due torncongenital anomalies. In Ethiopia, there are a number of babies are born with congenitalrnanomalies; however, a few studies have been studied regarding the prevalence and risk factorsrnfor the anomalies. Objective: The main objective of this study was to assess the prevalence ofrncongenital anomalies and associated factors among newborns in Bishoftu general hospital,rnOromia, Ethiopia. Methods: descriptive retrospective crossectional study was employed. Therndata entry and analysis was conducted by using SPSS version 24. Categorical variables werernsummarized as proportions and were compared using Pearson’s Chi square test, Crudern(unadjusted) and adjusted odds ratios were calculated to quantify the strength of associationrnbetween the factors and congenital anomalies. The 95% confidence intervals were determinedrnand the factors with a p-value of less than 0.05 were considered to have a significant associationrnwith congenital anomalies. Result: Out of 2218 live births 23 newborns were diagnosed withrncongenital malformations, making the prevalence rate of 1% per 100 live births. The mostrncommon prevalent types of congenital anomaly were anencephaly (30.4%).Maternal age abovern35(AOR =6.5, 95%CI = (2.4-18), P value= 0.001),birth order above 3(AOR=8.4; 95%CI=3.420.7;rnPrnvaluern=0.001),rnbirthrnweightrnlessrnthanrn2.5(AOR=0.3;95%CI=0.1-0.9),Prnvalue=0.037)rnrnandrnrnsingletonrnrnpregnancy(AOR =6.4;95%CI =2-18.9,P value =0.001) had a significant associationrnwith the occurrence of congenital anomalies, whereas maternal use folic acid duringrnpregnancy(AOR=0.036; 95% CI =.0.008-0.15;Pvalue=0.001) had a protective effect againstrncongenital anomalies. Conclusion and recommendation: Congenital anomaly is common and rnaccounts for 1 %( 10/1000 live births) in Bishoftu general hospital and anencephaly is the most rnprevalent type followed by hydrocephalus and spinal bifida. Large community-based studies inrndifferent geographical, environmental and socio-economic settings should be conducted inrnEthiopia to determine the prevalence of congenital anomalies and their associated factors.
