We investigated patterns and correlates of multiple, adult-onset cancer risk factors (MCRFs) among adolescents. Baseline data from an intervention efficacy trial were analyzed to examine patterns of co-occurring MCRFs and sociodemographic and theoretical (e.g., prevention self-efficacy) correlates of MCRFs among adolescents (N = 50) age 13 – 21. The mean total MCRFs was 4.6 (SD = 1.6; range 0–9). The most common risk factors were intentions to use alcohol (n = 40, 80%), < 5 daily servings of fruits/vegetables (n = 40, 80%), and lifetime alcohol use (n = 38, 76%). MCRFs commonly co-occurred, suggesting a clustered risk profile. Greater age (B = 0.19 95% CI 0.01, 0.38) and lower prevention self-efficacy (B = −0.16, 95% CI −0.02, −0.30) were significantly (p < 0.05) associated with MCRFs. Multiple health behavior change interventions are needed to prevent accumulation of risk factors as youth mature. Self-efficacy may be an important target for prevention interventions.
