Introduction: Concerns about the quality of life (QoL) of parents of children with autism spectrum disorder have been raised by previous study. Policy decision-makers and healthcare professionals can be better informed about the environmental factors associated with parental QoL, which will enhance outcomes for both parents and children. The objective of this review is to perform a comprehensive review that assesses the environmental relevant factors associated with quality of life (QoL) of parents of ASD children (under 18 years old). Methods: To identify the environmental factors associated with parental QoL, a scoping review was conducted using the Arksey and O'Malley original and enhanced framework. Three electronic database (PubMed, Scopus & WOS) and reference list checks were used in the search. Results: Social support, family support, residential condition, and access to services were all factors linked to the parental quality of life in this group. Conclusions The review highlighted environmental factors as one of the variables that have an association with parental QoL. The results of this analysis also highlighted potential areas of support that have implications on future policy and practices.

Introduction: Air pollutants, including PM2.5, are an increasing threat to public health. Studies have reported the adverse effect of PM2.5 exposures during pregnancy on neurodevelopment in children. We performed a narrative review using the PubMed, Web of Science, and Scopus databases from 2017 to 2022 using keywords such as prenatal, particulate matter, neurodevelopment, and children. This review aims to identify symptoms of impaired neurodevelopment in children associated with prenatal PM2.5 exposure, the association between the timing of prenatal exposure PM2.5 and symptoms of impaired neurodevelopment in children as well as other factors that may influence the association of prenatal PM2.5 exposure and symptoms of impaired neurodevelopment in children Methods: A total of 25 articles were included in this review. Results: Symptoms of neurodevelopmental impairment associated with prenatal exposure to PM2.5 include language, speech, and communication symptoms; motor skills; behaviour and social skills; memory as well as learning/cognitive symptoms. Neurodevelopmental impairments were associated with exposure to PM2.5 across all three trimesters with impairment in communication and behavioural domains predominating in those exposed during the first trimester. Conclusions Generally, males were more susceptible to having neurodevelopmental impairment symptoms compared to females. More information regarding the effect of prenatal PM2.5 exposure on neurodevelopmental domains of children will support public health policies that reduce air pollution and improve children’s health.
