The association between parental ADHD and adverse outcomes in children: Evidence from a Swedish nationwide register-based study

ASSOCIATION BETWEEN PARENTAL ADHD AND ADVERSE OFFSPRING OUTCOMES: EVIDENCE FROM A NATIONWIDE SWEDISH REGISTER-BASED STUDY

Parental ADHD is associated with an increased risk across psychiatric, behavioral, and somatic outcomes in children, with the highest risk when both parents have an ADHD diagnosis.

The study aimed to examine the association between parental attention-deficit/hyperactivity disorder (ADHD) and a broad range of psychiatric, behavioral, and somatic outcomes in children, and to assess whether these associations differed between maternal and paternal ADHD. Linked Swedish national registers were used to examine 1.16 million children born between 2000 and 2014; 32,170 children had a mother with an ADHD diagnosis, 29,699 had a father with an ADHD diagnosis, and 4,425 had two parents with an ADHD diagnosis. Children with and without parental ADHD were compared across 24 outcomes using matched Cox regression. For psychiatric outcomes, hazard ratios (HRs) were 1.50 (95% confidence interval 1.43 to 1.57) for autism, 1.45 (1.38 to 1.51) for anxiety, 1.32 (1.21 to 1.45) for conduct disorder, 1.31 (1.24 to 1.38) for major depressive disorder, and 1.27 (1.16 to 1.40) for tic disorder; the HR for intellectual disability was 0.92 (0.84 to 1.00). For behavioral outcomes, HRs were 1.38 (1.25 to 1.52) for assault or victimization, 1.35 (1.23 to 1.47) for poisoning, 1.20 (1.12 to 1.28) for intentional self-harm, 1.20 (1.12 to 1.29) for suicidal behavior, 1.16 (1.11 to 1.20) for traumatic brain injury, 1.09 (1.08 to 1.11) for accidental injury, 1.05 (1.04 to 1.07) for falls, and 1.04 (1.01 to 1.08) for transport-related injuries. Among somatic conditions, the highest risk was observed for sleep disorders (HR 1.51; 1.43 to 1.59), followed by asthma at 1.25 (1.22 to 1.28), obesity at 1.24 (1.18 to 1.31), autoimmune diseases at 1.16 (1.10 to 1.22), viral infections at 1.16 (1.14 to 1.19), bacterial infections at 1.14 (1.12 to 1.16), and gastrointestinal autoimmune diseases at 1.12 (1.03 to 1.22). The confidence intervals for epilepsy, 1.05 (0.96 to 1.15), and type 1 diabetes, 1.01 (0.90 to 1.15), included 1. In conclusion, parental ADHD is associated with an increased risk across psychiatric, behavioral, and somatic outcomes in children, with the highest risk when both parents have ADHD; these findings indicate that the impact extends beyond ADHD itself to encompass broader health and developmental vulnerabilities.
