What Increases the Risk for Alcohol Use Disorder?
A person’s risk for developing AUD depends in part on how much, how often, and how quickly they consume alcohol. Alcohol misuse—defined as drinking in a manner, situation, amount, or frequency that could cause harm to the person who drinks or to those around them—over time increases the risk of AUD. Alcohol misuse includes binge drinking and heavy alcohol use. Other factors also increase the risk of AUD, such as:
Drinking at an early age. A recent national survey found that among people ages 26 and older, those who began drinking before age 15 were more than three times as likely to report having AUD in the past year as those who waited until age 21 or later to begin drinking.3 The risk for females in this group is higher than that of males.
Genetics and family history of alcohol problems. Genetics play a role, with hereditability accounting for approximately 60%; however, like other chronic health conditions, AUD risk is influenced by the interplay between a person’s genes and their environment. Parents’ drinking patterns may also influence the likelihood that a child will one day develop AUD.
Mental health conditions and a history of trauma. A wide range of psychiatric conditions—including depression, post-traumatic stress disorder, and attention deficit hyperactivity disorder—are comorbid with AUD and are associated with an increased risk of AUD. People with a history of childhood trauma are also vulnerable to AUD.
