Introduction prenatal development could be considered normal or abnormal. Abnormal development occurs because of interference of normal development from genetic disorders, environmental factors, and multifactorial inheritances during the critical period of embryogenesis. The present study was aimed at evaluating the prevalence and patterns of birth defects among newborns in southwestern Ethiopia. Methods institutions-based cross-sectional study design was conducted in six purposively selected hospitals in southwestern Ethiopia based on their caseload. The study included data's from 2011 to 2015, during which 45,951 deliveries were recorded. All records of births in the selected hospitals were screened from medical records to identify the presence and types of birth defects. Results out of twenty-one different birth defects identified, nearly half of them belong to anencephaly and hydrocephalus. Five types of birth defects, namely: anencephaly (25.0%), hydrocephalus (24.6%), spina bifida (13.1%), meningomyelocele (7.1%), and umbilical hernia (4.8%) accounted for about three-fourths (75%) of all recorded birth defects. The prevalence rate of birth defects at birth was 55 per 10,000 births. Conclusion in the present study, the neural tube defects were identified to be the most prevalent. Nearly equal proportions of birth defects occurred among male and female newborns. The majority of the mothers who gave birth to newborns with birth defects were younger than 35 years. The high prevalence of birth defects revealed in this study call for the need to implement urgent prevention strategies including but not limited to the provision of sustained family planning, youth education and antenatal care services, and strict observation of rational medication use during pregnancy to curb the possible occurrences of the birth defect.

Background : Intrauterine development can be considered as normal development as well as abnormal development. Abnormal development commonly called birth defects occur because of interference of normal development from genetic disorders, environmental factors and the combination of both genetic and environment factors during the critical period of embryogenesis. The present study aimed to evaluate the prevalence and patterns of birth defects at birth in Southwestern Ethiopia. Methods : Institutions based cross-sectional study design was used. Six hospitals were selected from the existing hospitals in southwestern Ethiopia purposively based on case load. The study was conducted from September 2011 to December 2015 during which 45,951 deliveries were attained. All records of births that were occurred in the selected hospitals during the study period were identified from medical records, to locate the birth defect records.Results : Twenty-one different birth defects were recorded. Of these, 49.6 % of the birth defects recorded were Anencephaly and Hydrocephalus. Five types of birth defects namely: Anencephaly (25.0%), Hydrocephalus (24.6%), Spinal bifida (13.1%), Meningomyelocele (7.1%), and Umbilical hernia (4.8 %) accounted about three-fourth (75%) of all recorded birth defects. The present study revealed that the prevalence of the birth defects at birth was found to be 5.5 per 1000 births. Among twenty one birth defects identified in this study, the neural tube defects were the most frequent with prevalence rate of 4.1 per 1000 birth followed by gastrointestinal defects (0.7 per 1000 births)Conclusions: As compared to other study, the prevalence of birth defect identified in the present study was found to be higher. The neural tube defects were the most prevalent with the frequency of 4.05 cases per 1000.The present study also identified that nearly equal proportions of birth defect occurred among males and females newborns. The majority of the mother who gave birth to birth defects was younger than 35 years old. As the birth defect was found to be a main cases of infant mortality and morbidity, there need to an urgent interventions to control the cases.
