Diabetes mellitus is a challenging chronic health condition at the forefront of attention of the healthcare system. Important estimates quantifying how diabetes prevalence varies by age are available for the general population, but these estimates are poorly characterized among autistic adults. Improved diabetes prevalence and likelihood estimates…

Autism has been associated with increased mortality risk among adult populations, but little is known about the mortality risk among children and young people (0-24 years). We used a 15-year nationwide birth cohort study using linked health and non-health administrative data to estimate the mortality risk among Autistic children and young people…

This study estimated the prevalence of autism spectrum disorder in a 5-year inpatient cohort of children and adolescents diagnosed with first-episode psychosis in two Hong Kong teaching hospitals, and explored the clinical characteristics predicting first-episode psychosis-autism spectrum disorder comorbidity. The autism spectrum disorder…

There is a long tradition of research into autistic people's executive function skills. Yet, despite decades of research on EF in autism, the existing literature remains contradictory and 'confusing', with a large -- and unresolved -- discrepancy between small-to-moderate effect sizes demonstrated on laboratory-based EF tasks and large effect…

Motor stereotypies are frequently reported in individuals with autism spectrum disorder, but determinants of stereotypies remain poorly understood. In this study, a randomized sample of children with diagnosis of autism spectrum disorder was investigated to identify the prevalence and determinants of stereotypies. A total of 134 children who…

Obsessive-compulsive disorder commonly co-occurs with autism. Research characterising the interplay between restricted, repetitive behaviours, activities and interests related to autism and obsessive-compulsive disorder symptoms has used theory-driven, bottom-up methodology. This study aimed to interview autistic adults about the subjective…

In the past 40 years, accumulating evidence suggested that autistic individuals are at an increased risk of suicidal thoughts and behaviors. This study examined the occurrence of various potential risk factors for lifetime suicidal behavior and suicidal thoughts in the past month in a Dutch cohort (Netherlands Autism Register) of autistic…

Autistic children often have comorbid somatic problems. However, in adulthood, this has been much less studied. We investigated the associations between autistic symptoms and irritable bowel syndrome, food allergy, pain, and fatigue in adulthood and examined sex and life-course differences herein. A total of 35,048 adults aged from 18 to 90 from…

Fragile X syndrome (FXS), the leading heritable cause of intellectual disability, has a co-occurrence rate of autism spectrum disorder (ASD) estimated at ~60%. The onset and rates of motor development in FXS are slower relative to neurotypical development, and even more so in the context of co-occurring FXS + ASD. Extant evidence suggests these…

Shared family meals are associated with family functioning and thought to protect against disordered eating in families with neurotypical children. Limited research, however, has examined the mealtime structure or experience in families with children with autism (Autism spectrum condition) and/or attention deficit hyperactivity disorder, despite…

Autism spectrum disorder is a neurodevelopmental condition characterized by social communication difficulties and restricted, repetitive behaviors. Autism spectrum disorder is highly co-morbid with other neuro-psychiatric disorders such as attention deficit hyperactivity disorder, anxiety, and depression. However, research on post-traumatic stress…

Mental health conditions such as anxiety, depression, aggression, and inattention are common in autistic youth and are challenging to treat by community providers. We aim to parse the heterogeneity of autism based on dimensions of executive function and determine whether specific executive function profiles are differentially related to…

Despite very high rates of suicidal thoughts and behaviors (STB) in autistic adults, the key psychosocial drivers of this phenomenon remain unknown. To investigate, we examined how lifetime stressor exposure and severity, which have been found to predict STB in non-autistic populations, related to STB in a multinational dataset of 226 autistic…

Research shows significant rates of depressive symptoms in people with autistic spectrum disorder and intellectual disabilities. Finding factors related to the development of depression in autism spectrum disorder and intellectual disability is necessary. Emotion regulation is associated with depression in autism spectrum disorder and intellectual…

Autism spectrum disorder shares many symptoms with other mental health disorders, and comorbid disorders such as mood and anxiety disorders are common, making the diagnostic process challenging. We aimed to explore the diagnostic accuracy of two standard autism spectrum disorder diagnostic instruments and to identify those behavioral items that…
