Low Apgar scores linked to higher risk of ADHD
Findings of a population-based cohort study indicate that a low Apgar score at 5 minutes in newborns is associated with a higher risk of attention-deficit/hyperactivity disorder (ADHD) in childhood.
Findings of a population-based cohort study indicate that a low Apgar score at 5 minutes in newborns is associated with a higher risk of attention-deficit/hyperactivity disorder (ADHD) in childhood.
Danish researchers studied the association between Apgar scores at 5 minutes and ADHD in 980,902 singletons born from 1988 to 2001. All children were monitored from age 3 years to a first diagnosis of hyperkinetic disorder, first medication for ADHD, migration, death, or end of 2006, whichever came first.
The risk of ADHD increased with decreasing Apgar scores at 5 minutes, independent of potential confounding factors such as low birth weight, prematurity, ADHD comorbidities, family history of mental illness, maternal socioeconomic status, and maternal smoking. The risk of ADHD was 75% higher in children with Apgar scores of 1 to 4 and 63% higher in those with scores of 5 to 6 compared with children with scores of 9 or 10 at 5 minutes.
According to the researchers, their findings, together with previous observations, indicate that the Apgar score may be useful in predicting subtler neurodevelopment disabilities such as ADHD.
