Brief Summary
- 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.

Outcome Measures
Primary Outcomes (1)
To compare the effectiveness of standard of care therapy, in terms of change in CARS score after 6 months follow up, in two groups of children with autism spectrum disorder, during months with high air pollution and low air pollution, based on AQI
Difference in the change in mean CARS score between the two groups at 6 months follow up
6 months
Secondary Outcomes (6)
To compare the effectiveness of standard of care therapy, in terms of change in CARS score after 12 months follow up, in two groups of children with autism spectrum disorder, during months with high air pollution and low air pollution, based on AQI
12 months
To compare the impact on cognitive ability, as measured in terms of change in DQ/SQ/IQ after 6 months follow up, in two groups of children with autism spectrum disorder, during months with high air pollution and low air pollution, based on AQI
12 months
To compare the impact on sleep habits, as measured in terms of change in CSHQ score after 6 months follow up, in two groups of children with autism spectrum disorder, during months with high air pollution and low air pollution, based on AQI
12 months
To compare the impact on behavioral profile, as measured in terms of change in CBCL score after 6 months follow up, in two groups of children with autism spectrum disorder, during months with high air pollution and low air pollution, based on AQI
12 months
To assess the corelation between the air quality parameters (PM2.5, PM10) and the severity of autism spectrum disorder/sleep issues/behavioural issues and cognition at the end of 6 months follow up
12 months
- +1 more secondary outcomes
Study Arms (2)
Children with autism spectrum disorder followed up during the months with lower air pollution
* First group of children with autism spectrum disorder who meet the inclusion and exclusion criteria will be enrolled in the study after due informed consent in the month of April 2025. * The children will be followed up for a period of 6 months till September 2025 when they will be evaluated for primary outcome- CARS-2 score and other secondary outcomes-behavioural issues/sleep issues/cognitive ability. * They will further be followed up for the next 6 months till March 2026 to be evaluated for secondary outcomes.
Children with autism spectrum disorder followed up during the months with higher air pollution
* Second group of children with autism spectrum disorder who meet the inclusion and exclusion criteria will be enrolled in the study after due informed consent in the month of October 2025. * The children will be followed up for a period of 6 months till March 2026 when they will be evaluated for primary outcome- CARS-2 score and other secondary outcomes-behavioural issues/sleep issues/cognitive ability. * They will further be followed up for the next 6 months till September 2026 to be evaluated for secondary outcomes.
Interventions
standard of care therapy with behavioural and occupational therapy along with other pharmacological therapy as required

Biospecimen
Three millilitres of blood sample will be collected from every 5th patient from each group, at the end of 6 months follow up,. Samples will be collected only from those patients who provide consent for the same. A total of 10 samples, 5 from each group will be collected and analysed.
