This recent study explored the relationship between prenatal alcohol exposure (PAE) and sleep disturbances in more than 10,000 adolescents aged 12–13 years using data from the Adolescent Brain Cognitive Development (ABCD) Study. The researchers examined whether even low-to-moderate alcohol exposure during pregnancy was associated with later sleep difficulties. Findings showed that adolescents with prenatal alcohol exposure experienced higher rates of parent-reported sleep problems, particularly related to sleep–wake transitions, excessive daytime sleepiness, and sleep breathing concerns. The study adds to growing evidence that there may be no known safe level of alcohol exposure during pregnancy.
Three Key Takeaways
- Even low-to-moderate prenatal alcohol exposure was linked to sleep difficulties in adolescence.
Adolescents with any prenatal alcohol exposure experienced greater overall sleep disturbances compared to those without exposure.- The most impacted sleep areas were sleep–wake transitions, excessive daytime sleepiness, and sleep breathing.
The study found increased problems with fragmented sleep, unusual sleep behaviours, and daytime fatigue among youth with prenatal alcohol exposure.- Exposure early in pregnancy may be particularly important.
Youth whose prenatal alcohol exposure occurred before pregnancy recognition appeared to have more sleep-related concerns, reinforcing concerns about alcohol use during early fetal development.
