Why Some Adolescents Drink
April, 2009 marks the 22nd year of Alcohol Awareness Month.
Tarzana Treatment Centers is participating with a series of articles meant to inform and educate the general public about alcohol abuse, dependence and treatment. Considering that over 21 million Americans meet the criteria for alcohol abuse and over 53 million admit to past-month binge drinking, not to mention the many loved ones affected by each, our efforts are worthwhile.
Any parent should find the information below useful. It is from a 2006 report released by the National Institute on Alcohol Abuse and Alcoholism. This section can help parents of teens identify possible signs of adolescent alcohol abuse, and to discuss alcohol education or treatment if necessary. Parents of younger children may find ways to prevent future problems.
There is also information for those with alcoholism in the family already. While genetics play a part in alcoholism, there are other factors to consider in preventing teen alcohol abuse.

WHY DO SOME ADOLESCENTS DRINK?
As children move from adolescence to young adulthood, they encounter dramatic physical, emotional, and lifestyle changes. Developmental transitions, such as puberty and increasing independence, have been associated with alcohol use. So in a sense, just being an adolescent may be a key risk factor not only for starting to drink but also for drinking dangerously.
Risk-Taking—Research shows the brain keeps developing well into the twenties, during which time it continues to establish important communication connections and further refines its function. Scientists believe that this lengthy developmental period may help explain some of the behavior which is characteristic of adolescence—such as their propensity to seek out new and potentially dangerous situations. For some teens, thrill-seeking might include experimenting with alcohol. Developmental changes also offer a possible physiological explanation for why teens act so impulsively, often not recognizing that their actions—such as drinking—have consequences.
Expectancies—How people view alcohol and its effects also influences their drinking behavior, including whether they begin to drink and how much. An adolescent who expects drinking to be a pleasurable experience is more likely to drink than one who does not. An important area of alcohol research is focusing on how expectancy influences drinking patterns from childhood through adolescence and into young adulthood. Beliefs about alcohol are established very early in life, even before the child begins elementary school. Before age 9, children generally view alcohol negatively and see drinking as bad, with adverse effects. By about age 13, however, their expectancies shift, becoming more positive. As would be expected, adolescents who drink the most also place the greatest emphasis on the positive and arousing effects of alcohol.
Sensitivity and Tolerance to Alcohol—Differences between the adult brain and the brain of the maturing adolescent also may help to explain why many young drinkers are able to consume much larger amounts of alcohol than adults before experiencing the negative consequences of drinking, such as drowsiness, lack of coordination, and withdrawal/hangover effects. This unusual tolerance may help to explain the high rates of binge drinking among young adults. At the same time, adolescents appear to be particularly sensitive to the positive effects of drinking, such as feeling more at ease in social situations, and young people may drink more than adults because of these positive social experiences.
Personality Characteristics and Psychiatric Comorbidity—Children who begin to drink at a very early age (before age 12) often share similar personality characteristics that may make them more likely to start drinking. Young people who are disruptive, hyperactive, and aggressive—often referred to as having conduct problems or being antisocial—as well as those who are depressed, withdrawn, or anxious, may be at greatest risk for alcohol problems. Other behavior problems associated with alcohol use include rebelliousness, difficulty avoiding harm or harmful situations, and a host of other traits seen in young people who act out without regard for rules or the feelings of others (i.e., disinhibition).
Hereditary Factors—Some of the behavioral and physiological factors that converge to increase or decrease a person’s risk for alcohol problems, including tolerance to alcohol’s effects, may be directly linked to genetics. For example, being a child of an alcoholic or having several alcoholic family members places a person at greater risk for alcohol problems. Children of alcoholics (COAs) are between 4 and 10 times more likely to become alcoholics themselves than are children who have no close relatives with alcoholism. COAs also are more likely to begin drinking at a young age and to progress to drinking problems more quickly.
Research shows that COAs may have subtle brain differences which could be markers for developing later alcohol problems. For example, using high-tech brain-imaging techniques, scientists have found that COAs have a distinctive feature in one brainwave pattern (called a P300 response) that could be a marker for later alcoholism risk. Researchers also are investigating other brainwave differences in COAs that may be present long before they begin to drink, including brainwave activity recorded during sleep as well as changes in brain structure and function.
Some studies suggest that these brain differences may be particularly evident in people who also have certain behavioral traits, such as signs of conduct disorder, antisocial personality disorder, sensation-seeking, or poor impulse control. Studying how the brain’s structure and function translates to behavior will help researchers to better understand how predrinking risk factors shape later alcohol use. For example, does a person who is depressed drink to alleviate his or her depression, or does drinking lead to changes in his brain that result in feelings of depression?
Other hereditary factors likely will become evident as scientists work to identify the actual genes involved in addiction. By analyzing the genetic makeup of people and families with alcohol dependence, researchers have found specific regions on chromosomes that correlate with a risk for alcoholism. Candidate genes for alcoholism risk also have been associated with those regions. The goal now is to further refine regions for which a specific gene has not yet been identified and then determine how those genes interact with other genes and gene products as well as with the environment to result in alcohol dependence. Further research also should shed light on the extent to which the same or different genes contribute to alcohol problems, both in adults and in adolescents.
Environmental Aspects—Pinpointing a genetic contribution will not tell the whole story, however, as drinking behavior reflects a complex interplay between inherited and environmental factors, the implications of which are only beginning to be explored in adolescents. And what influences drinking at one age may not have the same impact at another. As Rose and colleagues show, genetic factors appear to have more influence on adolescent drinking behavior in late adolescence than in mid-adolescence.
Environmental factors, such as the influence of parents and peers, also play a role in alcohol use. For example, parents who drink more and who view drinking favorably may have children who drink more, and an adolescent girl with an older or adult boyfriend is more likely to use alcohol and other drugs and to engage in delinquent behaviors.
Researchers are examining other environmental influences as well, such as the impact of the media. Today alcohol is widely available and aggressively promoted through television, radio, billboards, and the Internet. Researchers are studying how young people react to these advertisements. In a study of 3rd, 6th, and 9th graders, those who found alcohol ads desirable were more likely to view drinking positively and to want to purchase products with alcohol logos. Research is mixed, however, on whether these positive views of alcohol actually lead to underage drinking.
