The incidence of birth defects refers to the ratio of the number of birth defects cases to the number of births in the current year, expressed as a percentage. [ 1]
The incidence of birth defects is influenced by many factors. With the improvement of people's quality of life, there should be fewer and fewer birth defects. However, due to the acceleration of industrialization and urbanization, problems such as environmental pollution and food processing pollution will follow. So it increases the probability of birth defects. In addition, with the progress of medical technology, the intervention of birth defects is becoming more and more common, and at the same time, birth defects that cannot be detected by the original technology and equipment can be detected gradually. So the incidence of birth defects will be higher and higher.
