HealthDay News — Paternal use of selective serotonin reuptake inhibitors (SSRIs) before conception is associated with increased risk of attention-deficit/hyperactivity disorder (ADHD) in offspring, according to a study published online in Pediatrics.
Fen Yang, from Fudan University in Shanghai, and colleagues conducted a cohort study involving 781,470 singletons born between 1996 and 2008 who were followed through 2013. Children whose fathers used SSRIs during the 3 months preceding conception were identified as exposed.
The researchers found that 0.92% of children were born to fathers who had used SSRIs during the 3 months prior to conception. Overall, 12,520 children were diagnosed with ADHD. After adjustment for potential confounders, exposed children had a 26% increased risk of ADHD compared with unexposed children (hazard ratio [HR], 1.26; 95% CI, 1.06-1.51). When extending the exposure window to 1 year before conception, similarly increased risk of ADHD was seen for paternal use of SSRIs only during the period of 12 to 3 months before conception and during the last 3 months before conception (adjusted HRs, 1.35 [95% CI, 1.10-1.66] and 1.31 [95% CI, 0.95-1.82]).
“The mildly increased risk of ADHD in offspring associated with paternal SSRI use before conception could probably be due to the underlying indications related to SSRI use,” the authors write.
