The effects of heavy drinking extend beyond those who use alcohol, a new study reports. Each year, one in five American adults are harmed as a result of someone else's drinking. People report threats of harassment, vandalism, physical aggression, financial and family problems, and harm from DUIs as main problems associated with other people's drinking. Researchers say the type of harm experienced differ by gender, with women more likely to report financial or family problems, and men reporting physical aggression and vandalism more often. Women are more likely to experience harm as a result of a family member's drinking, while men are more likely to be harmed as a result of alcohol use by a person outside the family. Even those who don't drink heavily are at three times higher risk of antisocial behaviors.
18 genetic variants have been identified which appear to be associated with alcohol use disorder and heavy drinking. Of these genes, five were overlapped, eight were associated with heavy consumption and five were linked to an increased risk of AUD. The study concluded that while heavy drinking is a risk factor for alcoholism, it is not a sufficient cause of the disorder.
