1. Air quality is a growing concern for health and environment and is one of the modifiable environmental factors. There is growing evidence that a complex interplay of genetic and epigenetic factors like environmental factors, underlies the pathophysiology of ASD. Behavioural issues, sleep habits and cognitive abilities play a significant role in the quality of life of both the affected children and their caregivers 2. Few studies have shown that there is an increased incidence of ASD in children born to mothers exposed to higher levels of air pollution in pregnancy. However, no studies on the effect of air quality on the severity of autism. There are limited studies on the association of air pollution with childhood behaviour and cognitive abilities, especially in neurodevelopmental disorders. No evidence on the impact of air quality on the effectiveness of therapy/standard of care in children with autism, as well as on their sleep habits and behaviour. Our study aims to add to this growing body of evidence of the effect of air pollution on ASD in children.
