Insights

Children with developmental coordination disorder (DCD) engage in less moderate to vigorous physical activity (MVPA), impacting their health. Interventions should consider strength, activity types, and family factors to boost MVPA and well-being.

Area of Science:

  • Pediatric Health
  • Exercise Science
  • Developmental Pediatrics

Background:

  • Motor proficiency is linked to physical activity levels in children.
  • Children with developmental coordination disorder (DCD) may face higher risks of inactivity and associated health issues like cardiovascular disease.
  • Understanding physical activity patterns in DCD is crucial for targeted health interventions.

Purpose of the Study:

  • To compare physical activity patterns, body composition, strength, and cardiovascular fitness in children with and without DCD.
  • To identify factors influencing moderate to vigorous physical activity (MVPA) in children with DCD.
  • To inform strategies for promoting health benefits of MVPA in this population.

Main Methods:

  • A comparative study involving 18 children aged 7-11 years, with and without DCD (n=9 per group).
  • Assessment of motor coordination, physical activity levels (MVPA), strength, cardiovascular fitness, body mass index (BMI), and relevant family factors.
  • Statistical analysis to compare groups and identify correlations between MVPA and other measured variables.

Main Results:

  • Children with DCD exhibited significantly lower MVPA levels compared to their peers without DCD.
  • Children with DCD presented with higher BMIs and reduced strength and cardiovascular fitness.
  • Strength, types of activities engaged in, and family factors were significantly correlated with MVPA in children with DCD.

Conclusions:

  • Children with DCD are at a disadvantage regarding MVPA, potentially increasing their risk for chronic health conditions.
  • Interventions aimed at increasing MVPA in children with DCD should incorporate strategies focusing on improving strength and diversifying activity types.
  • Family involvement, including parental perception of motor abilities and parental participation in activities, plays a significant role in promoting MVPA for children with DCD.

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.
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.
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;...
