TL;DR: Lower, not higher, socioeconomic status was associated with an increased risk of ASD, and studies finding the opposite may be underestimating the burden of ASD in lower SES groups.

TL;DR: Children with ASD and ASD traits have higher depressive symptom scores than the general population by age 10 years, which persist to age 18 years, particularly in the context of bullying, which could be a target for interventions.

TL;DR: Depression is overrepresented in autism spectrum disorders, and this higher risk may not be explained by shared familial liability; research identifying modifiable pathways may help develop preventive interventions.

TL;DR: Social communication impairments are an important autistic trait in relation to suicidality and future research identifying other potentially modifiable mechanisms may lead to interventions against suicidal behavior in this high-risk group.

TL;DR: Rates of almost all individual anxiety disorders were raised, notably obsessive–compulsive disorder and phobic anxiety disorders, and were more common in full siblings and half-siblings of people with ASD.
