Insights

Low Apgar scores at birth are linked to a higher risk of attention deficit hyperactivity disorder (ADHD) in children. This association suggests potential shared causes or that low Apgar scores may indicate pathways leading to ADHD.

Area of Science:

  • Neonatal Health
  • Child Psychology
  • Epidemiology

Background:

  • Apgar scores assess a newborn's physical condition.
  • Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder.
  • The relationship between Apgar scores and ADHD risk requires further investigation.

Purpose of the Study:

  • To determine if low Apgar scores at 5 minutes post-birth correlate with an increased risk of developing ADHD.
  • To analyze the dose-response relationship between Apgar scores and ADHD incidence.

Main Methods:

  • Nationwide population-based cohort study in Denmark (1988-2001).
  • Inclusion of 980,902 singletons.
  • Follow-up from age 3 until ADHD diagnosis, medication, migration, death, or end of 2006.
  • Cox regression models used to assess the association between Apgar scores and ADHD.

Main Results:

  • An inverse association was observed between Apgar scores and ADHD risk.
  • Children with Apgar scores of 1-4 had a 75% higher risk of ADHD compared to those with scores of 9-10.
  • Children with Apgar scores of 5-6 had a 63% higher risk of ADHD.

Conclusions:

  • Low Apgar scores at 5 minutes are significantly associated with an increased risk of childhood ADHD.
  • The findings suggest potential shared underlying causes for low Apgar scores and ADHD.
  • Low Apgar scores may represent a marker for causal pathways contributing to ADHD development.

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.
