Family structure and alcohol use disorder: a register-based cohort study among offspring with and without parental alcohol use disorder.

The prevalence of non-intact family structure appears to be higher in offspring of parents with alcohol use disorder (AUD) than among offspring from the general population. Parental AUD appears to be associated with increased risk of offspring AUD, and non-intact family structure appears to be associated with increased risk of offspring AUD regardless of parental AUD.
