Risk factors for autism spectrum disorder in the Thai population.

Unlabelled: Autism spectrum disorder (ASD) is a heterogeneous neurodevelopmental disorder commonly prevalent in children worldwide including Thailand. However, there are very few studies thus far addressing risk factors for ASD in Thai children. This case-control study aims to investigate whether various risk factors especially socioeconomic status, advanced parental age (age >35 years), perinatal factors, maternal autoimmune diseases, and family history of neuropsychiatric illnesses were associated with the risk of having an offspring with ASD.
