Identifying trends in smoking behaviors among youth cigarette smokers could inform youth policy and interventions.
Using 2011-2018 National Youth Tobacco Survey data, logistic/linear regressions were used to analyze trends in smoking frequency, intensity, age of first cigarette use, and electronic cigarette (e-cigarette) use frequency among current smokers. Stratified analyses were conducted among male, female, middle school, and high school students and race and ethnicity subgroups separately.
From 2011 to 2018, there was a decrease in smoking ≥10 days (50.0% to 38.3%), ≥20 days (37.2% to 26.3%), and 30 days (26.6% to 18.2%) among current smokers. Smoking prevalence decreased among male, female, high school, non-Hispanic white, and non-Hispanic other students. Overall, light smoking (≤5 cigarettes per day [CPDs]) increased (76.6% to 82.7%), and moderate smoking (6-10 CPDs) decreased (10.7% to 8.3%). Trends in light, moderate, and heavy smoking varied by demographic groups. Age at first cigarette use increased among female (12.28 to 13.29), high school (12.91 to 13.18), and non-Hispanic other students (11.64 to 12.83) and decreased among male students (12.90 to 12.57). From 2014 to 2018, there was an increase in e-cigarette use frequency for ≥10 days (20.8% to 40.9%), ≥20 days (13.5% to 31.7%), and all 30 days (9.3% to 22%).
From 2011 to 2018, current youth cigarette smokers smoked fewer days and fewer CPDs, and age of first cigarette use increased. However, over time, male youth smoked more heavily and started smoking earlier. E-cigarette use increased from 2014 to 2018. Differences by demographic characteristics can inform future research and interventions.
了解青少年吸烟者吸烟行为的趋势可以为青少年政策和干预措施提供信息。
使用 2011-2018 年全国青少年烟草调查数据，采用逻辑/线性回归分析了当前吸烟者吸烟频率、吸烟强度、首次吸烟年龄和电子烟使用频率的趋势。分别对男、女、中学和高中学生以及种族和族裔亚组进行了分层分析。
从 2011 年到 2018 年，当前吸烟者吸烟≥10 天（50.0%至 38.3%）、≥20 天（37.2%至 26.3%）和 30 天（26.6%至 18.2%）的比例有所下降。男性、女性、高中生、非西班牙裔白人和其他非西班牙裔学生的吸烟率均有所下降。总体而言，轻度吸烟（≤5 支/天[CPD]）有所增加（76.6%至 82.7%），中度吸烟（6-10 CPD）有所减少（10.7%至 8.3%）。轻、中、重度吸烟的趋势因人口统计学群体而异。女性（12.28 至 13.29）、高中生（12.91 至 13.18）和其他非西班牙裔学生（11.64 至 12.83）的首次吸烟年龄增加，而男学生（12.90 至 12.57）的首次吸烟年龄减少。从 2014 年到 2018 年，电子烟使用频率≥10 天（20.8%至 40.9%）、≥20 天（13.5%至 31.7%）和所有 30 天（9.3%至 22%）的比例有所增加。
从 2011 年到 2018 年，当前青少年吸烟者吸烟天数和每天吸烟量减少，首次吸烟年龄增加。然而，随着时间的推移，男性青少年吸烟量增加，开始吸烟的年龄更早。从 2014 年到 2018 年，电子烟的使用有所增加。人口统计学特征的差异可以为未来的研究和干预措施提供信息。
