       Youth Risk Behavior Surveillance -- United States 1997
       =======================================================

    Too many youth practice behaviors that place them at risk for
    serious injury, sexually transmitted diseases, other preventable
    health problems and even premature death, according to data
    released today from the 1997 Youth Risk Behavior Surveillance
    System (YRBSS), the most comprehensive survey of high school
    student health behaviors, including data for the nation, 36 states
    and territories and 17 cities. The priority health risk behaviors
    monitored include: behaviors that contribute to injury, tobacco
    use, alcohol and other drug use, sexual behaviors, dietary
    behaviors, and physical activity.

    In the U.S., 73% of all deaths among school-age youth and young
    adults result from four causes: motor vehicle crashes, other
    unintentional injuries, homicide, and suicide. Results from the
    YRBSS suggest that many high school students practice behaviors
    that may increase their likelihood of death from these causes --
    such as not wearing seat belts and carrying a weapon. Also,
    substantial health and social problems among youth result from
    unintended pregnancies and sexually transmitted diseases, including
    HIV infection and AIDS. In addition, since 67% of all deaths among
    adults result from heart disease, stroke, and cancer, the YRBSS
    measures risk behaviors such as physical inactivity and poor
    nutrition, which are often initiated during adolescence.

    Considerable variation in the prevalence of risk behaviors occurs
    from state to state. Thirty-four behaviors had a three-fold or
    greater variation among the states. The following ten behaviors had
    a four-fold or greater variation among the states:

    Behaviors that contribute to unintentional and intentional injuries

       - Rarely or never wearing a seat belt -- 6.1% to 36.5%.
       - Driving after drinking alcohol -- 8.1% to 33.2%.

    Tobacco, alcohol, and other drug use

       - Frequent cigarette use -- 7.3% to 27.6%.
       - Current smokeless tobacco use -- 3.4% to 22.5%.
       - Lifetime injected drug use -- 0.8% to 4.2%.
       - Cigarette use on school property -- 6.5% to 25.3%.
       - Smokeless tobacco use on school property -- 1.9% to 15.2%.

    Sexual behaviors

       - Initiated sexual intercourse before 13 years of age -- 3.8% to 21.2%.
       - Currently abstinent --22.9% to 35.7%.

    Physical activity

       - Attended physical education class daily -- 7.3% to 62.2%.
