Tobacco use is the leading cause of preventable disease and death in the United States; nearly all tobacco product use begins during youth and young adulthood (1,2). CDC and the Food and Drug Administration (FDA) analyzed data from the 2019 and 2020 National Youth Tobacco Surveys (NYTS) to determine changes in the current (past 30-day) use of seven tobacco products among U.S. middle (grades 6-8) and high (grades 9-12) school students. In 2020, current use of any tobacco product was reported by 16.2% (4.47 million) of all students, including 23.6% (3.65 million) of high school and 6.7% (800,000) of middle school students. Electronic cigarettes (e-cigarettes) were the most commonly used tobacco product among high school (19.6%; 3.02 million) and middle school (4.7%; 550,000) students. From 2019 to 2020, decreases in current use of any tobacco product, any combustible tobacco product, multiple tobacco products, e-cigarettes, cigars, and smokeless tobacco occurred among high school and middle school students; these declines resulted in an estimated 1.73 million fewer current youth tobacco product users in 2020 than in 2019 (6.20 million) (3). From 2019 to 2020, no significant change occurred in the use of cigarettes, hookahs, pipe tobacco, or heated tobacco products. The comprehensive and sustained implementation of evidence-based tobacco control strategies at the national, state, and local levels, combined with tobacco product regulation by FDA, is warranted to help sustain this progress and to prevent and reduce all forms of tobacco product use among U.S. youths (1,2).
在美国,吸烟是可预防疾病和死亡的主要原因;几乎所有烟草制品的使用都始于青少年和青年时期(1,2)。疾病预防控制中心和食品药品监督管理局(FDA)分析了 2019 年和 2020 年全国青少年烟草调查(NYTS)的数据,以确定美国中(6-8 年级)和高(9-12 年级)中学生当前(过去 30 天)使用七种烟草制品的情况变化。2020 年,所有学生中有 16.2%(447 万人)报告当前使用任何烟草制品,其中包括 23.6%(365 万人)的高中生和 6.7%(80 万人)的初中生。电子烟(电子烟)是高中生(19.6%;302 万人)和初中生(4.7%;55 万人)中最常用的烟草制品。从 2019 年到 2020 年,高中生和初中生当前使用任何烟草制品、任何可燃烟草制品、多种烟草制品、电子烟、雪茄和无烟烟草制品的人数均有所下降;这些下降导致 2020 年当前青少年烟草制品使用者比 2019 年(620 万人)减少了 173 万人(3)。从 2019 年到 2020 年,香烟、水烟、烟斗烟丝或加热烟草制品的使用没有明显变化。需要在国家、州和地方各级全面和持续实施基于证据的烟草控制策略,并由 FDA 对烟草制品进行监管,以帮助维持这一进展,并防止和减少美国青少年使用所有形式的烟草制品(1,2)。
