  美国食品药品管理局Karen A. Cullen联合美国疾病预防控制中心Brian A. King小组研究了2020年电子烟在美国年轻人中的使用情况。这一研究成果于2020年11月5日在线发表于《美国医学会杂志》。

  2011-2020年,美国年轻人吸电子烟率逐年上升。继续监测年轻人中电子烟和其他烟草产品的使用情况,对于宣传公共卫生政策、规划和监管工作尤为重要。

  2020年2月15日至5月24日,研究组对参加2020年全国青年烟草调查的19018名6至12年级的美国各校学生进行横断面分析。对他们的电子烟使用频率、品牌和口味进行统计和分析。

  调查对象包括10097名高中生,平均年龄为16.1岁,和8837名初中生,平均年龄为12.7岁。调查有效率为66.3%。据估计,27.5%的高中生和10.5%的初中生自述目前在吸电子烟。在这些吸电子烟的学生中,估计有34.2%的高中生和18.0%的初中生经常吸电子烟,63.6%的高中生和65.4%的初中生只吸电子烟。

  59.1%的高中生和54.1%的初中生表示在过去一月内经常吸JUUL牌的电子烟,13.8%的高中生和16.8%的初中生则表示并未固定吸某个品牌。在只吸电子烟的学生中,72.2%的高中生和59.2%的初中生吸调味电子烟,其中水果、薄荷醇或薄荷、糖果、甜点或其他甜食口味最受欢迎。

  研究组得出结论,2020年高中生和初中生电子烟使用率较高,很多学生经常吸,且大多数吸调味电子烟。

  Abstract:

  Importance The prevalence of e-cigarette use among US youth increased from 2011 to 2020. 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 2020 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 2020 National Youth Tobacco Survey. The survey was conducted from February 15, 2020, to May 24, 2020.

  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 2020, 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.
