The National Institutes of Health estimates that nearly 17.6 million Americans are either alcoholics or alcohol abusers. The many risks associated with alcoholism are concerning – for a variety of reasons – to family members of alcoholics. Chief among their concerns is the inheritability of alcoholism.
For decades, scientists have been studying and documenting the fact that alcoholism runs in families. Recently, they have discovered a genetic link which proves relatives of alcoholics are at greater risk of becoming alcoholics themselves. Most of the studies have been conducted using twins – both identical and fraternal. They have found that there are greater incidents of alcoholism in identical twins, who share the same genetic makeup. This genetic link is not the only factor, but it is a strong one. Studies have found that children of alcoholics are about four times more likely to have alcohol-related problems than the general population. There is also a greater tendency towards behavioral and emotional problems.
The environment in which a person grows up also strongly influences his alcohol-related risks. Studies have found four contributing factors to a child’s risk of developing alcoholism:
The discovery is not meant to be a dire prophecy for those who have an alcoholic in their families. Rather, it should serve as a warning, and compel those at greatest risk to take preventative steps.
Young people who have an alcoholic parent or grandparent should avoid drinking at an early age. Not only is underage drinking illegal, but studies have shown that people who begin drinking during adolescence are much more likely to become alcoholics.
If you are an adult whose family has a history of alcoholism, avoid excessive drinking. The U.S. Department of Health defines “moderate” drinking as no more than one drink per day for women, and no more than two drinks per day for men. Consider talking to a health care professional about your family history and your concerns.
