重要性从2011年到2018年，电子烟在美国年轻人中的普及率有所上升。持续监测电子烟和其他烟草产品在青少年中的使用情况，对于公共卫生政策、规划和监管工作具有重要意义。目的评估2019年美国高中生和中学生电子烟的使用情况，包括使用频率、品牌和风味产品的使用。设计、设置和参与者对参加2019年全国青年烟草调查的19018名具有全国代表性的美国学生进行横断面分析。这项调查是在2019年2月15日至2019年5月24日进行的。MAIN的结果和衡量标准包括：高中生和中学生自我报告的当前(过去30天)电子烟使用估计数；当前电子烟使用者中频繁使用电子烟(>；=过去30天内20天)和常用电子烟品牌；以及按学校级别和常用品牌划分的当前专用电子烟使用者(未使用其他烟草产品)中加味电子烟的使用情况和口味类型。结果本次调查包括10097名高中生(平均年龄16.1[3.0]岁；女性占47.5%)和8837名中学生(平均年龄12.7[2.8]岁；女性占48.7%)。有效率为66.3%。据估计，27.5%(95%可信区间，25.3%~29.7%)的高中生和10.5%(95%可信区间，9.4%~11.8%)的中学生表示目前使用电子烟。在目前的电子烟使用者中，估计有34.2%(95%CI，31.2%~37.3%)的高中生和18.0%(95%CI，15.2%~21.2%)的中学生表示经常使用电子烟，63.6%(95%CI，59.3%~67.8%)的高中生和65.4%(95%CI，60.6%~69.9%)的中学生表示专门使用电子烟。在目前的电子烟使用者中，估计有591%(95%CI，54.8%~63.2%)的高中生和54.1%(95%CI，49.1%~59.0%)的中学生在过去30天内将Juul作为他们经常使用的电子烟品牌；在目前的电子烟使用者中，13.8%(95%可信区间，12.0%~15.9%)的高中生和16.8%(95%可信区间，13.6%~20.7%)的中学生表示没有常用的电子烟品牌。在当前专属电子烟使用者中，估计有72.2%(95%CI，69.1%~75.1%)的高中生和59.2%(95%CI，54.8%~63.4%)的初中生使用加味电子烟，其中水果、薄荷或薄荷，以及糖果、甜点或其他甜食是最常见的口味。结论2019年，高中生和中学生自报电子烟使用率较高，目前许多电子烟用户报告经常使用电子烟，大多数独家电子烟用户报告使用加味电子烟。
IMPORTANCE The prevalence of e-cigarette use among US youth increased from 2011 to 2018. Continued monitoring of the prevalence of e-cigarette and other tobacco product use among youth is important to inform public health policy, planning, and regulatory efforts.OBJECTIVE To estimate the prevalence of e-cigarette use among US high school and middle school students in 2019 including frequency of use, brands used, and use of flavored products.DESIGN, SETTING, AND PARTICIPANTS Cross-sectional analyses of a school-based nationally representative sample of 19 018 US students in grades 6 to 12 participating in the 2019 National Youth Tobacco Survey. The survey was conducted from February 15, 2019, to May 24, 2019.MAIN OUTCOMES AND MEASURES Self-reported current (past 30-day) e-cigarette use estimates among high school and middle school students; frequent use (>= 20 days in the past 30 days) and usual e-cigarette brand among current e-cigarette users; and use of flavored e-cigarettes and flavor types among current exclusive e-cigarette users (no use of other tobacco products) by school level and usual brand. Prevalence estimates were weighted to account for the complex sampling design.RESULTS The survey included 10 097 high school students (mean [SD] age, 16.1 [3.0] years; 47.5% female) and 8837 middle school students (mean [SD] age, 12.7 [2.8] years; 48.7% female). The response rate was 66.3%. An estimated 27.5%(95% CI, 25.3%-29.7%) of high school students and 10.5%(95% CI, 9.4%-11.8%) of middle school students reported current e-cigarette use. Among current e-cigarette users, an estimated 34.2%(95% CI, 31.2%-37.3%) of high school students and 18.0%(95% CI, 15.2%-21.2%) of middle school students reported frequent use, and an estimated 63.6%(95% CI, 59.3%-67.8%) of high school students and 65.4%(95% CI, 60.6%-69.9%) of middle school students reported exclusive use of e-cigarettes. Among current e-cigarette users, an estimated 59.1%(95% CI, 54.8%-63.2%) of high school students and 54.1%(95% CI, 49.1%-59.0%) of middle school students reported JUUL as their usual e-cigarette brand in the past 30 days; among current e-cigarette users, 13.8% (95% CI, 12.0%-15.9%) of high school students and 16.8%(95% CI, 13.6%-20.7%) of middle school students reported not having a usual e-cigarette brand. Among current exclusive e-cigarette users, an estimated 72.2%(95% CI, 69.1%-75.1%) of high school students and 59.2%(95% CI, 54.8%-63.4%) of middle school students used flavored e-cigarettes, with fruit, menthol or mint, and candy, desserts, or other sweets being the most commonly reported flavors.CONCLUSIONS AND RELEVANCE In 2019, the prevalence of self-reported e-cigarette use was high among high school and middle school students, with many current e-cigarette users reporting frequent use and most of the exclusive e-cigarette users reporting use of flavored e-cigarettes.
