Introduction
Congenital anomaly is a serious global public health problem, because it is a major cause of child mortality and morbidity worldwide. Congenital anomaly causes lifelong disability and considerable impacts on the health care system. In 2015, congenital anomaly is responsible for nearly 276 000 neonatal deaths around the world; 95 % of the deaths come from low-middle income countries (1) (2). Prevalence and pattern of congenital anomalies have been reported in developed countries. However, there are surprisingly few data on this matter in countries with limited resources.
Viet Nam is a low-middle income country with a population of approximately 90 million people and the accurate birth prevalence of congenital anomalies is difficult
