Sexual Behavior. Surveys of adolescents suggest that alcohol use is associated with risky sexual behavior and increased vulnerability to coercive sexual activity. Among adolescents surveyed in New Zealand, alcohol misuse was significantly associated with unprotected intercourse and sexual activity before age 16 (60). Forty-four percent of sexually active Massachusetts teenagers said they were more likely to have sexual intercourse if they had been drinking, and 17 percent said they were less likely to use condoms after drinking (61).
Risky Behavior and Victimization. Survey results from a nationally representative sample of 8th and 10th graders indicated that alcohol use was significantly associated with both risky behavior and victimization and that this relationship was strongest among the 8th-grade males, compared with other students (62).
Puberty and Bone Growth. High doses of alcohol have been found to delay puberty in female (63) and male rats (64), and large quantities of alcohol consumed by young rats can slow bone growth and result in weaker bones (65). However, the implications of these findings for young people are not clear.
Prevention of Adolescent Alcohol Use
Measures to prevent adolescent alcohol use include policy interventions and community and educational programs. Alcohol Alert No. 34: Preventing Alcohol Abuse and Related Problems (66) covers these topics in detail.

Youth Drinking: Risk Factors and Consequences--A Commentary by
NIAAA Director Enoch Gordis, M.D.
Alcohol, the most widely used and abused drug among youth, causes serious and potentially life-threatening problems for this population. Although alcohol is sometimes referred to as a "gateway drug" for youth because its use often precedes the use of other illicit substances, this terminology is counterproductive; youth drinking requires significant attention, not because of what it leads to but because of the extensive human and economic impact of alcohol use by this vulnerable population.
For some youth, alcohol use alone is the primary problem. For others, drinking may be only one of a constellation of high-risk behaviors. For these individuals, interventions designed to modify high-risk behavior likely would be more successful in preventing alcohol problems than those designed solely to prevent the initiation of drinking. Determining which influences are involved in specific youth drinking patterns will permit the design of more potent interventions. Finally, we need to develop a better understanding of the alcohol treatment needs of youth. Future questions for scientific attention include, what types of specialized diagnostic and assessment instruments are needed for youth; whether treatment in segregated, "youth only" programs is more effective than in general population programs; and, irrespective of the setting, what types of specific modalities are needed by youth to increase the long-term effectiveness of treatment.
