Insights

This study identified key risk factors for suspected developmental delay (SDD) in 2-year-olds. Early screening and interventions targeting factors like maternal education and home environment can improve child development outcomes.

Area of Science:

  • Pediatrics
  • Developmental Psychology
  • Public Health

Background:

  • Child development is crucial for lifelong potential.
  • Epidemiological studies identify factors influencing development.
  • Early identification of developmental delays is essential for timely intervention.

Purpose of the Study:

  • To identify risk factors for suspected developmental delay (SDD) at age 2 years.
  • To inform public health policies and pediatric interventions for preventing developmental delays.
  • To analyze a comprehensive set of maternal, child, and environmental factors associated with SDD.

Main Methods:

  • Utilized data from the 2004 Pelotas Birth Cohort in Brazil.
  • Administered the Battelle Screening Developmental Inventory (BSDI) at age 2 years.
  • Employed multivariable Poisson regression with confounder adjustment to determine risk factors.

Main Results:

  • 3.3% of children screened positive for SDD.
  • Key risk factors included early screening positive results, low Apgar scores, low maternal education, lower socioeconomic status, gestational diabetes, short birth intervals, lack of story-telling, limited home literature, low birth weight, preterm birth, insufficient antenatal care, prior hospitalization, and male sex.
  • Prevalence ratios (PR) and 95% confidence intervals [95% CI] were calculated for each factor.

Conclusions:

  • Identified multiple modifiable and non-modifiable risk factors for SDD.
  • Findings can guide targeted interventions to support child development.
  • Highlights the importance of socioeconomic and environmental factors in early childhood development.

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.
Introduction to Developmental Psychology01:27

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...
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.
Socioemotional Development during Infancy01:30

Socioemotional Development during Infancy

Socio-emotional development in infancy is primarily shaped by early emotional responses and social connections, with temperament playing a central role. Temperament refers to the consistent patterns in an individual's emotional and behavioral responses, observable even in infancy. By examining temperament, researchers can better understand an infant's unique ways of interacting with the world, influencing subsequent personality and socio-emotional growth.

Bias in Epidemiological Studies

Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:
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;...
