Insights

The prevalence of developmental delay (DD) in children aged 0-6 years in Taiwan increased significantly from 1997 to 2008. Boys showed a higher prevalence of DD compared to girls, highlighting a critical concern for early intervention strategies.

Area of Science:

  • Pediatrics
  • Public Health
  • Epidemiology

Background:

  • Developmental delay (DD) affects a significant number of children globally.
  • Understanding the prevalence and trends of DD is crucial for public health planning and resource allocation.
  • Taiwan's National Health Insurance Research Database provides a robust dataset for longitudinal studies on child health.

Purpose of the Study:

  • To estimate the prevalence of developmental delay (DD) in children aged 0-6 years in Taiwan.
  • To analyze age-period trends in the diagnosis of DD within the study population.
  • To identify disparities in DD prevalence based on sex.

Main Methods:

  • Utilized a longitudinal dataset from Taiwan's National Health Insurance Research Database (1997-2008).
  • Included 2,308,790 children aged <6 years at baseline, followed until age 5.
  • Analyzed annual prevalence rates and sex-specific prevalence ratios.

Main Results:

  • The prevalence of DD in children aged 0-6 years increased from 0.16% to 3.25% between 1997 and 2008.
  • A consistent increasing trend in DD prevalence was observed over the 12-year study period.
  • Boys exhibited a 2.13 times higher prevalence of DD compared to girls.

Conclusions:

  • Developmental delay prevalence in Taiwanese children shows a significant upward trend.
  • Sex is a significant factor influencing DD prevalence, with boys being more affected.
  • Further research is needed to understand the gap between early treatment rates and DD prevalence for effective intervention.

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.

Intellectual Disability

Intellectual disability (ID) is a neurodevelopmental condition characterized by deficits in intellectual and adaptive functioning that manifest during the developmental period. This condition encompasses challenges in reasoning, memory, problem-solving, and learning, accompanied by impairments in everyday life skills, such as communication, self-care, and social interactions. Intellectual disability affects approximately 1% of the population in the United States, impacting an estimated 5...

Learning Disabilities

Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.

Introduction to Developmental Psychology

Developmental psychology explores the changes and continuities in human abilities throughout life, encompassing physical, cognitive, linguistic, and social dimensions. Human development is not restricted to growth, but includes aspects of decline, particularly in physical abilities as individuals age. Developmental psychologists seek to understand how people change as they age and how their mental and social skills evolve.Developmental MilestonesA key concept in developmental psychology is...

Three Developmental Domains

Human development is typically examined across three main domains: physical, cognitive, and socio-emotional. These domains represent the significant areas of change and continuity throughout the lifespan, from infancy to late adulthood.
Physical Development
Physical processes, also known as maturation, encompass the biological changes that occur across an individual's life. These changes begin with genetic inheritance and continue through various stages, including growth in height and weight,...

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.
