The study was conducted by taking a blood sample of 4,200 women who were pregnant at the age of 21 weeks. The blood sample measured its vitamin D levels, then noted. After the baby is born, it is repeated at once with a sample of the baby’s blood.
The study did not stop there, but after 6 years later the study was done again to see the condition of the baby who has grown. Are there any symptoms of autism suffered by children who have been part of the study or not.
From studies of blood samples and their vitamin D levels, as well as the existing condition of autism symptoms, it was concluded that mothers with vitamin D deficiency were more likely to have children with autism.
It is not experienced by mothers who have high levels of vitamin D because their children do not have symptoms of autism, as reported by Good Housekeeping page.
The results of this study are related to previous studies, which mentions that vitamin D has a role that is not small in the phase of brain formation when the fetus in the womb.
When the mother lacks vitamin D, then the baby is not only at risk of experiencing autism, but also asthma or schizophrenia.
