Given the increased prevalence of non-daily smoking and changes in smoking patterns, particularly among young adults, we examined correlates of smoking level, specifically motives for smoking, and readiness to quit smoking among 2682 college undergraduates who completed an online survey. Overall, 64.7% (n = 1736) were non-smokers, 11.6% (n = 312) smoked 1-5 days, 10.5% (n = 281) smoked 6-29 days and 13.2% (n = 353) were daily smokers. Ordinal regression analyses modeling smoking level indicated that correlates of higher smoking level included having more friends who smoke (β = 0.63, 95% CI 0.57-0.69) and more frequent other tobacco use (β = 0.04, 95% CI 0.02-0.05), drinking (β = 0.04, 95% CI 0.02-0.07) and binge drinking (β = 0.09, 95% CI 0.06-0.13). Bivariate analyses indicated that daily smokers (versus the subgroups of non-daily smokers) were less likely to smoke for social reasons but more likely to smoke for self-confidence, boredom, and affect regulation. Controlling for sociodemographics, correlates of readiness to quit among current smokers included fewer friends who smoke (P = 0.002), less frequent binge drinking (P = 0.03), being a social smoker (P < 0.001), smoking less for self-confidence (P = 0.04), smoking more for boredom (P = 0.03) and less frequent smoking (P = 0.001). Specific motives for smoking and potential barriers to cessation particularly may be relevant to different groups of college student smokers.
鉴于非每日吸烟的流行率增加以及吸烟模式的变化，特别是在年轻成年人中，我们调查了 2682 名大学生在线调查对象的吸烟水平、吸烟动机以及戒烟准备情况的相关因素。总体而言，64.7%（n=1736）为不吸烟者，11.6%（n=312）为 1-5 天吸烟，10.5%（n=281）为 6-29 天吸烟，13.2%（n=353）为每日吸烟者。对吸烟水平进行的有序回归分析表明，更高的吸烟水平与以下因素有关：有更多吸烟的朋友（β=0.63，95%置信区间为 0.57-0.69），更频繁地使用其他烟草制品（β=0.04，95%置信区间为 0.02-0.05），饮酒（β=0.04，95%置信区间为 0.02-0.07）和狂饮（β=0.09，95%置信区间为 0.06-0.13）。单变量分析表明，与非每日吸烟者相比，每日吸烟者更不可能出于社交原因而吸烟，但更有可能出于自信、无聊和情绪调节等原因而吸烟。在校正社会人口统计学因素后，当前吸烟者戒烟准备情况的相关因素包括：吸烟朋友较少（P=0.002），狂饮较少（P=0.03），社交吸烟者（P<0.001），因自信而吸烟较少（P=0.04），因无聊而吸烟较多（P=0.03）和吸烟频率较低（P=0.001）。特定的吸烟动机和潜在的戒烟障碍可能与不同群体的大学生吸烟者有关。
