Smoking Patterns and Their Relationship to Drinking in First-Year College Students
Menée à partir d'enquêtes en ligne auprès d'étudiants effectuant leur première année d'enseignement supérieur, cette étude américaine analyse leurs comportements tabagiques et la relation entre leur consommation d'alcool et leur fréquence tabagique
Introduction: Unlike older smokers, young adult smokers frequently engage in light and intermittent smoking. It remains unclear how stable such smoking patterns are over time, as substantial variability exists between these smokers. This study identified subgroups of college student smokers based on the trajectory of their smoking frequency during the first year of college, thereby examining stability versus instability over time. We then tested if the interplay between drinking and smoking differed in the identified groups, so as to determine the relative role drinking may play in intermittent versus more regular smoking. Methods : Incoming college students at 3 institutions completed online biweekly surveys of their daily substance use throughout the first year of college. Students who reported smoking at least 1 cigarette during this year (n = 266) were included in analyses (70% female, 74% White). Results : Group-based trajectory modeling identified 5 groups of smokers, 3 of which maintained their smoking frequency throughout the year (77%), and 2 groups of infrequent smokers showed significant trends (11% increasing, 12% decreasing). Notably, nondaily smoking was maintained at different specific frequencies (e.g., 1 vs. 3 days per week). Identified groups differed in the relationship between drinking and smoking, where cooccurrence was particularly strong in infrequent smokers, and trends in smoking quantity differed between groups. Conclusions : While there was a diversity of smoking patterns in the sample, patterns of intermittent smoking remain relatively stable for a majority of students throughout the year. Intervention messages targeting drinking and smoking should be tailored based on smoking frequency.
