Researchers at the National Institute on Alcohol Abuse and Alcoholism (NIAAA) examined data from a three-year study of 22,316 drinkers who are now 18 years or older. They looked at the associations between the first incidence of alcohol dependence or abuse and three age-of-first-drink groups—younger than 15, between 15 and 17, and 18 years or older.
Drinking Before Age 15 Increases the Risk of Alcoholism
The scientists were careful to control for other risk factors for developing drinking problems, such as family history, duration of exposure to alcohol and other childhood risk factors. Follow Now: Apple Podcasts / Spotify / Google Podcasts
Impaired Executive Cognitive Function
“Past studies have often suggested that this association might result from common risk factors predisposing people to both early drinking and alcohol use disorders. Although the current study does not provide conclusive evidence that early drinking directly increases alcohol use disorder risk, it suggests that it is premature to rule out the possibility of such a direct effect.” said Deborah A. Dawson, staff scientist at the NIAAA, in a news release. But the question they have not answered is whether the impaired executive cognitive function leads to heavy early-onset drinking, or the early heavy drinking causes the impaired executive cognitive function.
Alcoholism Prevention Should Target Younger Children
Regardless, the NIAAA researchers conclude that prevention programs and public health policies should be targeted at children under age 15 and underage drinking, in general, to try to delay the onset of drinking alcohol as long as possible. “The data support the notion of delaying the onset of drinking behavior as late as possible as an important principle for the prevention of alcohol use disorders later in life,” said NIAAA researcher Howard B. Moss. “More specifically, these findings provide the scientific basis for those prevention programs that focus on decreasing underage drinking, as well as supporting those public-health policies that are geared towards the prevention of underage drinking.”
