Abstract: | The authors followed 64,322 children and mothers enrolled in the Danish National Birth Cohort (DNBC; 1996-2002) for average 12.7 years to investigate whether acetaminophen use in pregnancy is associated with increased risk of ASD in the offspring. Information on acetaminophen use was collected prospectively from three computer-assisted telephone interviews. Records from the Danish hospital and psychiatric registries were used to identify diagnoses of ASD. At the end of follow up, 1,027 (1.6%) children were diagnosed with ASD, 345 (0.5%) with infantile autism. It was found that 31% of ASD (26% of infantile autism) have also been diagnosed with hyperkinetic disorders. More than 50% women reported ever using acetaminophen in pregnancy. The authors used Cox proportional hazards model to estimate hazard ratio (HR) and 95% confident interval (CI). Prenatal use of acetaminophen was associated with an increased risk of ASD accompanied by hyperkinetic symptoms (HR = 1.51 95% CI 1.19-1.92), but not with other ASD cases (HR = 1.06 95% CI 0.92-1.24). Longer duration of use (i.e., use for >20 weeks in gestation) increased the risk of ASD or infantile autism with hyperkinetic symptoms almost twofold. Maternal use of acetaminophen in pregnancy was associated with ASD with hyperkinetic symptoms only, suggesting acetaminophen exposure early in fetal life may specifically impact this hyperactive behavioral phenotype. |
