  1. Co-occurrence of health-risk behaviors among adolescents in the United States.

    Article - En anglais


    Although it is common for adolescents to experiment with several health-risk behaviors before reaching adulthood, little is known about the co-occurrence of these behaviors.

    The purposes of this study were to determine the co-occurrence of specific health-risk behaviors among a nationally representative sample of adolescents, and to examine whether the distribution of multiple risk behaviors varies by age, sex, and school enrollment status.


    This study analyzed survey data from a United States national probability sample (n=10,645) of youth aged 12-21 years.

    Survey items measuring current seat belt use, weapon carrying, tobacco, alcohol, and other drug use, and sexual behavior were included in the analysis.


    The majority of adolescents aged 12-17 years did not engage in multiple health-risk behaviors.

    However, the prevalence of multiple risk behaviors increased dramatically with age.

    While only 1 in 12 adolescents aged 12-13 years engaged in two or more of these behaviors, one-third of those aged 14-17 years and half of the college-aged youth (18-21 years) did so.

    Male respondents and out-of-school youth aged 14-17 years were more likely to engage in multiple health-risk behaviors than were other respondents.


    These results suggest that the likelihood that adolescents engage in multiple health-risk behaviors is related to age and that many adolescents engage in these behaviors serially rather than at the same time.
