What the study found
The study found no support for an association between labor epidural analgesia, a pain-relief method used during childbirth, and autism spectrum disorder (ASD) in offspring.
Why the authors say this matters
The authors say the findings address recent concerns about a possible link between labor epidural analgesia and ASD, and they conclude that their results do not support such an association.
What the researchers tested
The researchers analyzed mother-child pairs from the Study to Explore Early Development, a US multisite case-control study conducted from 2007 to 2020. They compared reported labor epidural analgesia use during childbirth with ASD status, which was determined by trained psychologists using the Autism Diagnostic Observation Schedule and Autism Diagnostic Interview-Revised.
What worked and what didn't
Among 2039 ASD cases and 3171 controls, labor epidural analgesia use was similar in both groups, at 66% and 67%. The crude odds ratio was 0.97 and the adjusted odds ratio was 1.02, both with confidence intervals that included no association. Sensitivity analyses were generally consistent, although some subtle associations appeared when the analysis was limited to vaginal deliveries and then weakened after additional adjustment for fetal distress, induced or augmented labor, and prolonged labor.
What to keep in mind
The abstract does not describe additional limitations beyond the subgroup analyses. The findings are based on this study's sample and methods, including case-control data and the specific ASD assessment tools used.
Key points
- The study found no support for an association between labor epidural analgesia and ASD in offspring.
- The analysis included 2039 ASD cases and 3171 controls from a US multisite case-control study.
- Labor epidural analgesia use was similar in cases and controls: 66% versus 67%.
- The adjusted odds ratio was 1.02, with confidence intervals that included no association.
- Sensitivity analyses were generally consistent, though subgroup findings in vaginal deliveries weakened after further adjustment.
