Insights
Paternal use of selective serotonin reuptake inhibitors (SSRIs) before conception is linked to a higher risk of attention-deficit/hyperactivity disorder (ADHD) in children. This association may stem from the conditions for which SSRIs are prescribed.
Area of Science:
- Reproductive Health
- Pediatric Neurology
- Psychopharmacology
Background:
- Maternal selective serotonin reuptake inhibitor (SSRI) use during pregnancy is a known risk factor for attention-deficit/hyperactivity disorder (ADHD) in offspring.
- The potential impact of paternal SSRI use on ADHD risk in children remains less understood.
Purpose of the Study:
- To investigate whether paternal SSRI use in the period preceding conception increases the risk of ADHD in offspring.
- To quantify the association between paternal SSRI exposure and ADHD diagnosis in children.
Main Methods:
- A large-scale Danish cohort study included 781,470 singletons born between 1996 and 2008, with follow-up data extending to 2013.
- Children exposed to paternal SSRI use within 3 months before conception were identified.
- Cox regression analysis was employed to calculate hazard ratios (HR) for ADHD, adjusting for potential confounding factors.
Main Results:
- Paternal SSRI use in the 3 months before conception was associated with a 26% increased risk of ADHD in offspring (HR = 1.26).
- Exposure during the period of 12 to 3 months before conception showed a HR of 1.35, while exposure in the last 3 months yielded a HR of 1.31.
- A total of 7,216 children were born to fathers using SSRIs before conception, with 12,520 children diagnosed with ADHD.
Conclusions:
- Paternal SSRI use prior to conception is associated with a mildly increased risk of ADHD in offspring.
- The observed association may be influenced by the underlying medical conditions necessitating SSRI treatment in fathers.
Objectives:
It has been shown that maternal prenatal exposure to selective serotonin reuptake inhibitors (SSRIs) may be a risk factor for attention-deficit/hyperactivity disorder (ADHD) in offspring. Our goal was to examine whether paternal SSRI use before conception increases the risk of ADHD in offspring.
Methods:
On the basis of Danish national registers, we conducted a cohort study of 781 470 singletons born between 1996 and 2008 with follow-up throughout 2013. The children whose fathers used SSRIs during the last 3 months before conception were identified as the exposed. Cox regression was used to estimate the hazard ratio (HR) of ADHD.
Results:
A total of 7216 children (0.92%) were born to fathers who had used SSRIs during the last 3 months before conception. There were 12 520 children diagnosed with ADHD. Compared with unexposed children, the exposed had a 26% increased risk of ADHD (HR = 1.26, 95% confidence interval [CI]: 1.06-1.51) after adjusting for potential confounders. When extending the exposure window to 1 year before conception, paternal use of SSRIs only during the period of 12 to 3 months before conception was associated with the HR of 1.35 (95% CI: 1.10-1.66), whereas paternal use of SSRIs only during the last 3 months before conception was associated with a similarly increased risk of ADHD (adjusted HR = 1.31, 95% CI: 0.95-1.82).
Conclusions:
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.
