Insights

Low Apgar scores at birth are linked to increased attention-deficit/hyperactivity disorder (ADHD) symptom severity in diagnosed children. This highlights the importance of prenatal and perinatal care for ADHD risk and management.

Area of Science:

  • Neurodevelopmental disorders
  • Pediatric neurology
  • Perinatal health

Background:

  • Adverse pregnancy and delivery events are associated with attention-deficit/hyperactivity disorder (ADHD).
  • Previous research explored the link between Apgar scores and ADHD risk.
  • The current study investigates Apgar scores in relation to ADHD symptom severity.

Purpose of the Study:

  • To examine the association between Apgar scores and ADHD symptom severity in children diagnosed with ADHD.
  • To determine if Apgar scores predict the intensity of ADHD symptoms.

Main Methods:

  • Compared ADHD symptom severity in children with low (≤6) versus higher (≥7) Apgar scores.
  • Recruited participants from an ADHD clinic.
  • Assessed symptom severity while participants were off medication.

Main Results:

  • Children with low 1-minute Apgar scores exhibited more severe ADHD symptoms.
  • Severity was measured using the Child Behaviour Checklist, Conners' Global Index for Parents, and DSM-IV hyperactivity counts.
  • Significant associations were found for all measures (P = 0.02, <0.01, <0.01).

Conclusions:

  • Low 1-minute Apgar scores are significantly associated with increased ADHD symptom severity.
  • These findings emphasize the critical role of optimal pregnancy and perinatal care.
  • Apgar scores may serve as an early indicator for potential ADHD symptom intensity.

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....
