Autism Comorbidities Reveal Hidden Health Burden in Children
New data highlights gastrointestinal, sleep, feeding, and anxiety disorders as key co-occurring conditions requiring routine screening
Children with autism spectrum disorder show significantly higher rates of gastrointestinal, sleep, feeding, and anxiety disorders compared to neurotypical peers, suggesting the need for routine, integrated screening and care.
Study Details
A large comparative review published in the Journal of Pediatric Health Care analyzed comorbidity patterns in children and adolescents with autism. The study aimed to better understand how frequently additional health conditions occur alongside autism and how these patterns vary by age and gender.
The findings reinforce a growing understanding that autism is not a single, isolated condition but often involves multiple overlapping medical and behavioral challenges.
Methodology
Researchers used electronic health record data collected between 2019 and 2021 from a regional health information exchange in southeastern North Carolina. The dataset included over 222,000 individuals aged 2 to 21 years, generating more than 1.9 million clinical records.
Among this population, 1,793 children were identified with autism. The researchers compared rates of 30 different diagnoses between children with autism and those without, focusing on gastrointestinal issues, feeding disorders, sleep disturbances, and anxiety conditions.
Key Findings
Children aged 5–10 with autism had significantly higher gastrointestinal issues (21.6% vs 5.2%)
Anxiety disorders were notably higher in ages 15–17 (22.1% vs 3.7%)
Sleep problems were elevated in ages 2–4 (14% vs 0.9%)
Feeding issues were also higher in younger children (14% vs 1.4%)
Anxiety peaked in young adults with autism (23.8% vs 5.8%)
Gender differences emerged:
Boys had higher feeding and sleep issues early in life
Girls showed more gastrointestinal issues in mid-childhood
Older girls had higher anxiety rates
Unexpected findings included:
Lack of insomnia among top diagnoses
Higher prevalence of seizure-related conditions
Social factors such as poverty, food insecurity, and lead exposure were more common in children with multiple comorbidities
Implications for Practice
For Patients and Families
This study reinforces that many challenges faced by children with autism may stem from underlying medical conditions that are treatable. Gastrointestinal discomfort, poor sleep, or feeding difficulties can significantly affect behavior, mood, and development.
Early identification and management of these issues may improve quality of life and reduce secondary complications such as anxiety.
For Healthcare Providers
The findings support a shift toward routine, structured screening for comorbidities in children with autism. This includes:
Gastrointestinal evaluation when behavioral symptoms worsen
Sleep assessments as part of routine care
Screening for feeding difficulties in early childhood
Early mental health evaluation, especially during adolescence
The study also highlights the importance of multidisciplinary care models, involving pediatricians, gastroenterologists, neurologists, behavioral specialists, and social services.
Clinicians should also consider social determinants of health, as factors like food insecurity and environmental exposure may influence both diagnosis and outcomes.
