Abstract Background Congenital anomaly is a partial or complete structural and/or functional defect during intrauterine life. Globally, major congenital anomalies account for 6% of all newborns among which about 94% of cases occurred in developing countries. In spite of its public health importance, very limited studies are reported in Ethiopia, and hardly any study in Arsi Zone. Objectives To determine the predictors of congenital anomalies among newborns in Arsi Zone Public Hospitals, Southeast Ethiopia. Methods A multi-center institutional-based case-control study was conducted in 418 (105 cases and 313 controls) of newborns in Arsi Zone Public Hospitals. Descriptive analysis, binary and multivariable logistic regressions were implemented. Results In this study, women who have been drinking alcohol during pregnancy were 3.48 times more prone to have newborns with congenital anomalies than their counterparts (AOR = 3.48; 95% CI: 1.38, 8.74). The likelihood of having a newborn with congenital anomalies was six and four times higher for women who had a maternal illness (AOR = 6.10; 95%CI: 2.39, 15.57) and chewing khat during pregnancy (AOR = 4; 95%CI: 1.49, 10.65), respectively. Moreover, the lack of folic acid supplementation and pesticides during pregnancy were 3.25 and 4.76 times more likely to experience a newborn with congenital anomalies, respectively. Conclusion Alcohol drinking, maternal illness, khat chewing, and chemical exposure during pregnancy had a significant association with the occurrence of congenital anomalies. While, taking folic acid supplements had a protective effect. Health experts and the community should take these factors into consideration and act accordingly.
