Oxygen deprivation during labor may also contribute to the development of autism. The etiology of autism is not yet fully understood. It is mainly considered to be a mental disorder caused by the interaction of genetic factors as well as environmental factors on the central nervous system. Some unfavorable factors during pregnancy can increase the chance of autism, such as the mother’s advanced age during pregnancy, the father’s age at the time of the mother’s pregnancy; the mother’s preterm miscarriage during pregnancy, viral infection, emotional instability, lack of oxygen or suffocation at the time of birth, etc., can increase the chance of autism. However, lack of oxygen at birth does not necessarily cause autism, it is only a high risk factor, but a more severe lack of oxygen at birth can lead to damage to brain cells, which can cause some sequelae. Such as common cerebral palsy, aspiration pneumonia, epilepsy, and even death. Therefore, for pregnant women who are ready to give birth in late pregnancy, we should pay attention to an abnormal symptom of the fetus, and once the labor starts, we should pay attention to go to the hospital in time, and carry out the delivery under the guidance of professional doctors.
