Abstract

Objective: To understand how factors at multiple levels of influence impact adolescent smoking initiation. Method: Data from the Minnesota Adolescent Community Cohort, a population-based cohort, were analyzed. Adolescents were recruited from randomly selected geopolitical units (GPUs) in Minnesota at ages 12 to 13 (n = 1953), and were surveyed every six months (2000-2006) until 18. The association between baseline social factors and smoking initiation was analyzed using logistic regression. Linear regression was used to analyze predictors and age of initiation among smokers (n = 603). Results: Higher proportion of 15-16. year-olds who smoke at the area-level (GPU) was associated with younger initiation (15.47 vs 15.87, p < .05). Higher proportion of the population employed and higher median household income were associated with older initiation (15.90 vs. 15.56 p < .05). Parent education, living with parents or siblings who smoke, living in homes that allow smoking, and having friends who smoke at baseline were associated with smoking initiation or younger initiation (p < .05). Participants whose parents had less than a high school education were 1.6 times more likely than those with college educated parents to have smoked at least a whole cigarette (CI = 1.06, 2.26). Conclusion: Factors at multiple levels of influence effect adolescent smoking initiation. Smoking by older age peers and lower SES predicts earlier smoking.
