The frequency and risk factors of allergy and asthma in children with autism--case-control study
Insights
Children with autism experience asthma and allergies at rates similar to neurotypical children. Parental allergy, particularly the father's, is a risk factor for allergies in autistic children.
Area of Science:
- Pediatric Allergy
- Autism Spectrum Disorder Research
- Childhood Comorbidities
Background:
- Autism Spectrum Disorder (ASD) evolution can be influenced by co-occurring conditions.
- Allergic diseases are highly prevalent in children and may impact ASD symptoms.
- Understanding the relationship between allergies and autism is crucial for comprehensive care.
Purpose of the Study:
- To compare the frequency of asthma and allergic diseases in children with autism versus controls.
- To identify risk factors for allergic diseases and asthma in both groups.
Main Methods:
- A case-control study involving 96 children with autism and 192 matched controls.
- Analysis conducted separately for autism and control groups to enable comparison.
- Matched controls by year of birth, gender, and physician's practice.
Main Results:
- No statistically significant difference in asthma or allergic disease frequency between children with autism and controls.
- Asthma affected 5.2% of children with autism and 4.7% of controls; allergies affected 25.0% and 21.9%, respectively.
- Father's history of allergy/asthma was a risk factor for allergies in children with autism.
Conclusions:
- Children with autism exhibit similar rates of asthma and allergies compared to children without autism.
- Allergic diseases in the father represent a significant risk factor for developing allergies in children with autism.
Introduction:
The evolution of autistic disorders in children depends on many factors, like concomitance of the other diseases, which can escalate the autistic symptoms. One of those groups are allergic diseases, which have one of the highest prevalence rates in children.
Objectives:
The aim of this analysis was to determine the frequency of asthma and allergy in children with autism in comparison to controls and the risk factors of allergic diseases and asthma in both groups.
Material And Methods:
Study population included 96 cases diagnosed with childhood or atypical autism and 192 controls matched individually by year of birth, gender and physician's practice. The analysis was performed in each group separately giving possibility to compare the results between study groups.
Results:
The frequency of asthma and allergic diseases in both groups has not revealed any statistically significant differences. Children with autism have been affected by asthma in 5,2% and by allergy in 25,0%, controls in 4,7% and 21,9% respectively. All cases of asthma was diagnosed in boys, commonly allergy was also more frequent in boys than girls in both studied groups. However those differences was statistically insignificant. The father's allergy and asthma was revealed as a risk factor of allergy in children with autism. In controls additionally allergy or asthma diagnosed in mother or grandparent increased risk of allergy in children.
Conclusions:
Children with autism were affected by asthma and allergy with similar frequency like children without autistic disorders. Allergy in father was the risk factor of allergic diseases in children with autism.

Autism Spectrum Disorder
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.
Asthma-I: Introduction
Asthma I: Introduction
Asthma-II: Pathophysiology and Classification
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:
Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
