Environmental risk factors stressors in the diatheses stress model or part of the pre-disposition depending on when they operate on the individual. Maternal smoking in 1st trimester: elevated risk that child will have the symptoms of autism, maternal anxiety, relationship between the two caesarean delivery: whatever it is that required a caesarean is what"s contributing to symptoms.
