    Article - En anglais


    To examine the evolution of risk behaviors over 2 years among a community-based cohort of low-income African American preadolescents and young adolescents enrolled in a randomized trial of an acquired immunodeficiency syndrome risk reduction intervention.


    Longitudinal, community-based cohort.


    Nine recreation centers serving 3 public housing developments.


    Three hundred eighty-three African American youths aged 9 through 15 years at baseline.


    Frequency distributions, X2 analyses, and regression analyses regarding 10 risk behaviors were conducted.

    To assess whether a specific risk behavior or its protective (nonrisk) behavioral analogue, composing a risk-nonrisk behavioral complex (eg, was sexually active and was sexually abstinent or used drugs and refrained from drugs), was stable over time, K values were determined for the 10 risk-nonrisk behavioral complexes.

    Main Outcome Measures 

    Instrument assessing risk behaviors administered at baseline and every 6 months aurally and visually via talking computer.


    The prevalence of sexual intercourse, cigarette smoking, alcohol consumption, and drug use increased notably over time.

    Drug use increased from a 6-month cumulative prevalence of 7% at baseline to 27% at the 24-month follow-up (P<. 001). (...)
