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…

Purpose: Almost all epidemiologic studies estimating autism spectrum disorder (ASD) prevalence have focused on school-age children. This study provides the first population-based data on the prevalence and expression of ASD among adolescents in a large US metropolitan region. Methods: Active multiple source ASD surveillance of adolescents aged…

Objective: Accumulating evidence indicates high rates of major depressive disorder (MDD) in children and adolescents with ADHD. This systematic review and meta-analysis aimed to examine the rate of depression in children and adolescents with ADHD who are without intellectual disability (ID). Method: A comprehensive search of six databases…

The prevalence of autism spectrum disorder (ASD) has increased in recent decades, much of which is related to changes in diagnostic criteria, and greater awareness among professionals and parents. Using a prospective cross-sectional study design, this study explores the prevalence of ASD among 173 adolescents admitted to two psychiatric facilities…

Our objective was to examine occurrence of both conditions in Medicaid; and compare Medicaid service use and cost, and chronic conditions among adults with Down syndrome and autism to those with Down syndrome alone and those with autism alone. We used ICD9 and ICD10 codes in Medicaid claims and encounters from 2011 to 2019 to identify autism and…

According to the Gallaudet Research Institution's most recent Annual Survey of Deaf and Hard of Hearing Children and Youth (2013), almost 40% of d/DHH students nationwide receive special education…

People with intellectual disabilities (ID) are vulnerable to multiple long-term conditions (MLTC). However, in the UK, there are no individual strategies tailored for them. This study synthesised evidence on prevalence of MLTC in people with ID alongside risk factors, outcomes and preventative strategies. The scoping review used the tool Abstrackr…

Recent research has suggested that people with autism spectrum disorder may be disproportionately at risk of substance use disorders. This study analyzed national-level Medicaid Claims data to compare substance use disorder prevalence among Medicaid enrollees with autism spectrum disorder (N = 388,426) and a random sample of enrollees without…

Autistic youth and youth with ADHD have heightened rates of bullying victimization, anxiety, and depression. The purpose of this research is to use nationally representative US data to (1) estimate the prevalence of anxiety and depression among bullied neurodivergent youth and (2) investigate whether the association between bullying victimization…

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…

Background: Suicidality in individuals with intellectual disability is a critical but under-researched area. This systematic review aims to synthesize existing literature on the prevalence, risk factors, and interventions for suicidality among individuals with intellectual disability. Methods: Adhering to the PRISMA guidelines, a comprehensive…

Prevalence of hearing loss in children with autism spectrum disorder (ASD) is uncertain, as it is more challenging to assess hearing function in children with developmental difficulties (DD). We aimed to determine the prevalence and profiles of hearing loss in preschool children with ASD in a Southeast-Asian population who passed newborn hearing…

Co-occurring intellectual/developmental disability (IDD) and overweight/obesity (OW/OB) is an important consideration of IDD psychiatric care. The relationship between OW/OB and comorbid diagnoses of Autism Spectrum Disorder (ASD) and/or IDD remains inadequately described in existing literature. The purpose of this study is to explore these…

Objective: The current study aimed to elucidate characteristics of co-occurring ADHD and anxiety in a community-based sample of children. Previous work has highlighted the prevalence and associated impairment of each condition alone, but less research has focused on the co-occurrence of these disorders. Method: The present study first sought to…
