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.

Autism Spectrum Disorder01:19

Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
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: Introduction01:29

Asthma-I: Introduction

Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Asthma I: Introduction01:28

Asthma I: Introduction

Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...

Asthma-II: Pathophysiology and Classification

Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
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 Management01:20

Asthma: Pathogenesis and Management

Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
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.

Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....
