Insights

Children with attention-deficit/hyperactivity disorder (ADHD) have a higher likelihood of experiencing infectious diseases (IDs). Healthcare providers should consider this association in pediatric care.

Area of Science:

  • Pediatric Health
  • Epidemiology
  • Infectious Diseases

Background:

  • Infectious diseases (IDs) represent a significant health burden in children.
  • Previous studies indicate a link between pediatric attention-deficit/hyperactivity disorder (ADHD) and specific infectious diseases.

Purpose of the Study:

  • To investigate the association between pediatric ADHD and the overall incidence of infectious diseases.
  • To determine if ADHD increases the risk for various pediatric infections.

Main Methods:

  • A population-based case-control study utilized Electronic Medical Records (EMRs) from Leumit Health Services (LHS).
  • The study included children and adolescents aged 5-18 years from January 1, 2006, to June 30, 2021.
  • Cases met ADHD criteria; controls were randomly selected (2:1 ratio) and matched by demographics. Diagnoses used ICD-9/10 criteria.

Main Results:

  • The study included 18,756 ADHD cases and 37,512 controls, with similar demographics.
  • Children with ADHD showed significantly higher rates of all infectious diseases compared to controls.
  • Specific infections with increased risk included acute respiratory infection (OR=1.4), acute gastroenteritis (OR=1.3), salmonellosis (OR=2.8), and urinary tract infection (OR=1.3).
  • Children with ADHD received anti-infective medications more frequently and had more physician visits.

Conclusions:

  • Findings suggest a significant association between infectious diseases and pediatric ADHD.
  • Healthcare providers should be aware of the increased risk of infections in children with ADHD.

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....

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.

Conduct Disorder01:28

Conduct Disorder

Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...

Oppositional Defiant Disorder01:30

Oppositional Defiant Disorder

A persistent pattern of angry or irritable mood, defiant behavior, or vindictiveness characterizes Oppositional Defiant Disorder (ODD). Symptoms must occur over at least six months, involve interactions with individuals beyond siblings, and meet specific diagnostic criteria to be clinically significant. The disorder affects emotional regulation, social interactions, and behavior, often manifesting early in life and influencing long-term development and functioning.

Immunodeficiency Diseases01:25

Immunodeficiency Diseases

Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...

Causality in Epidemiology01:21

Causality in Epidemiology

Causality or causation is a fundamental concept in epidemiology, vital for understanding the relationships between various factors and health outcomes. Despite its importance, there's no single, universally accepted definition of causality within the discipline. Drawing from a systematic review, causality in epidemiology encompasses several definitions, including production, necessary and sufficient, sufficient-component, counterfactual, and probabilistic models. Each has its strengths and...
