The children born to mothers without folic acid (FA) and micronutrient supplementation during pregnancy had more severe social cognition impairments, social communication impairments, autism behaviour mannerisms, developmental delays in adaptive and gross motor behaviour and gastrointestinal problems than children born to mothers who used FA and micronutrient supplements (P＜0.05). Interestingly, there was an association between maternal micronutrient supplementation and vitamin A (VA), vitamin D (VD) and folate levels in the ASD children (P<0.05), and levels of these vitamins also were associated with symptoms of ASD. Maternal FA and/or micronutrient supplementation may potentially moderate the symptoms of ASD. Interrupting the chain of micronutrient deficiencies between pregnant mothers and children may be beneficial in improving symptoms of ASD.
