Worldwide medical insurance customers might be interested to learn that the risk of developing alcohol use disorders (AUDs) can be passed from parents to offspring.
The research, due to be published in the journal Alcoholism: Clinical & Experimental Research, looked at a large population-based sample of Danish parents.
It found that, regardless of other significant predictors such as gender, parental social status and parental psychiatric hospitalisation with other diagnoses, children of parents with AUDs were more likely to have alcohol problems themselves.
Erik Lykke Mortenson, association professor in medical psychology at the University of Copenhagen and corresponding author of the study, said that the study is unusual in its scope.
He explained: "Longitudinal population studies are both expensive and take a long time to complete.
"In some countries it may also be a problem to follow several generations through decades. But in Denmark we have personal identification numbers and national health registries."
