Twin study of caffeine use, ADHD, and disrupted sleep in ABCD youth.

Conclusions: In a sample of preadolescent twin pairs from the ABCD Study, we did not observe evidence that caffeine use was quasi-causally associated with disrupted sleep at this early developmental stage. However, caffeine use and disrupted sleep emerged with shared etiologic influences. In sum, this study sets the stage for examining these dynamic patterns in future examinations of this critical and timely ABCD study sample, as genetic and environmental influences on behavior are known to change throughout development.
