The purpose of this study was to identify trends of tobacco use, among all students and current tobacco users, in a nationally representative sample of high school students from 1999 to 2013.
Trends in individual and concurrent use of cigarettes, cigars, and smokeless tobacco (SLT) products were tested using 8 repeated cross-sections of the YRBS between 1999 and 2013. Tests for effect modification of race/ethnicity and sex were conducted for each trend.
Among all students, there were significant non-linear changes detected for the concurrent use of all 3 products, and the dual use of cigarettes and cigars. Girls significantly increased their use of SLT. Among users, significant changes were detected for each individual product and all combinations. Female users significantly increased their concurrent use of cigarettes and cigars and concurrent use of cigarettes and SLT. Male users significantly decreased their use of cigarettes and cigars.
While the decrease in the youth prevalence of cigarette use is a public health success, there is concern about the increase in non-cigarette products, among tobacco users. These changes further drive increases in the concurrent use of tobacco products, adding to the potential health burden.
本研究旨在确定1999年至2013年全国具有代表性的高中生样本中，所有学生以及当前烟草使用者的烟草使用趋势。
使用1999年至2013年期间青少年风险行为监测系统（YRBS）的8个重复横断面数据，对香烟、雪茄和无烟烟草（SLT）产品的单独使用和同时使用趋势进行了测试。针对每种趋势，进行了种族/民族和性别的效应修饰检验。
在所有学生中，检测到所有三种产品同时使用以及香烟和雪茄同时使用存在显著的非线性变化。女孩使用无烟烟草的情况显著增加。在使用者中，每种单独产品及其所有组合均检测到显著变化。女性使用者同时使用香烟和雪茄以及同时使用香烟和无烟烟草的情况显著增加。男性使用者使用香烟和雪茄的情况显著减少。
虽然青少年吸烟率的下降是公共卫生领域的一项成就，但烟草使用者中使用非香烟产品的情况有所增加，令人担忧。这些变化进一步推动了烟草产品同时使用情况的增加，加重了潜在的健康负担。
