Which of the following factors is NOT commonly recognized as a risk factor for Autism?

High birth weight is not commonly recognized as a risk factor for autism. While various prenatal and perinatal factors have been studied in relation to autism spectrum disorder (ASD), high birth weight does not have a consistent association with increased risk for autism.

On the other hand, maternal age of 40 and up and paternal age of 50 and up have been identified in research as potential risk factors for autism due to the increased likelihood of genetic mutations or complications that can arise with advanced parental age. The use of misoprostol during pregnancy has also been linked to an elevated risk of various developmental issues, including autism, as it can affect fetal development. Thus, in the context of recognized risk factors for Autism, high birth weight stands out as not being connected to an increased risk for developing the disorder.
