Finally, we asked whether risk of young adult AUD increases as a function of cumulative exposure to parental EB. We compared the odds of developing young adult AUD when exposed to parental EB during 2 vs. 1, 3 vs. 1, and 3 vs. 2 time periods. Results (Table 5) demonstrate that a higher degree of exposure confers greater risk. Among those children exposed to parental EB, each period of exposure increased the child’s risk of developing AUD by young adulthood by up to an additional 50%.
