Purpose: To determine how the association between cigarette smoking and other risky behaviors, such as substance use, violence, and risky sexual practices, has changed between 1991 and 2003.
Methods: Youth Risk Behavior Surveys (YRBS) from 1991 to 2003 were analyzed. For each cohort, logistic regression models controlling for gender, race/ethnicity, and school grade were used to describe the associations between smoking and other risky behaviors. Changes in the odds ratios over time were confirmed with a trend analysis.
Results: The strength of the relationship between smoking and other risky behaviors increased for lifetime number of sexual partners (1991 odds ratio [OR] 1.49; 2003 OR 1.61 (p < .001)), sexual partners in the past 3 months (1991 OR 1.77; 2001 OR 2.05 (p < .001)), and never wearing a bicycle helmet 1991 OR 1.40; 1997 OR 5.94 (p < .001). Increases were also seen for binge drinking, and physical fighting. The association between cigarette smoking and marijuana use decreased slightly.
Conclusions: Future prevention efforts and tobacco intervention programs should recognize that current adolescent smokers are even more likely to engage in risky sexual behavior, risky alcohol-related behaviors, and to not use a seatbelt or bicycle helmet than were adolescents in the early nineties.
