Alcoholism - Risk Factors

Risk Factors

According to the U.S. National Institute of Alcohol Abuse and Alcoholism, about 70% of American adults always drink at low-risk levels or do not drink at all. (Thirty-five percent of Americans do not consume alcohol.) About 28% of American adults drink at levels that put them at risk for alcohol dependence and alcohol-related problems.

Risk factors for alcohol dependence include:

Age

Drinking in Adolescence. About half of under-age Americans have used alcohol. About 2 million people ages 12 - 20 are considered heavy drinkers, and 4.4 million are binge drinkers. Anyone who begins drinking in adolescence is at risk for developing alcoholism. The earlier a person begins drinking, the greater the risk. A survey of over 40,000 adults indicated that among those who began drinking before age 14, nearly half had become alcoholic dependent by the age of 21. In contrast, only 9% of people who began drinking after the age of 21 developed alcoholism.

Young people at highest risk for early drinking are those with a history of abuse, family violence, depression, and stressful life events. People with a family history of alcoholism are also more likely to begin drinking before the age of 20 and to become alcoholic. Such adolescent drinkers are also more apt to underestimate the effects of drinking and to make judgment errors, such as going on binges or driving after drinking, than young drinkers without a family history of alcoholism.

Drinking in the Elderly Population. Although alcoholism usually develops in early adulthood, the elderly are not exempt. In fact, doctors may overlook alcoholism when evaluating elderly patients, mistakenly attributing the signs of alcohol abuse to the normal effects of the aging process.

Alcohol also affects the older body differently. People who maintain the same drinking patterns as they age can easily develop alcohol dependency without realizing it. It takes fewer drinks to become intoxicated, and older organs can be damaged by smaller amounts of alcohol than those of younger people. Also, many of the medications prescribed for older people interact adversely with alcohol. Medications used for arthritis or pain pose a particular danger for interaction with alcohol.
