Tobacco use is the leading cause of preventable disease and death in the United States; if current smoking rates continue, 5.6 million Americans aged <18 years who are alive today are projected to die prematurely from smoking-related disease. Tobacco use and addiction mostly begin during youth and young adulthood. CDC and the Food and Drug Administration (FDA) analyzed data from the 2011-2015 National Youth Tobacco Surveys (NYTS) to determine the prevalence and trends of current (past 30-day) use of seven tobacco product types (cigarettes, cigars, smokeless tobacco, electronic cigarettes [e-cigarettes], hookahs [water pipes used to smoke tobacco], pipe tobacco, and bidis [small imported cigarettes wrapped in a tendu leaf]) among U.S. middle (grades 6-8) and high (grades 9-12) school students. In 2015, e-cigarettes were the most commonly used tobacco product among middle (5.3%) and high (16.0%) school students. During 2011-2015, significant increases in current use of e-cigarettes and hookahs occurred among middle and high school students, whereas current use of conventional tobacco products, such as cigarettes and cigars decreased, resulting in no change in overall tobacco product use. During 2014-2015, current use of e-cigarettes increased among middle school students, whereas current use of hookahs decreased among high school students; in contrast, no change was observed in use of hookahs among middle school students, use of e-cigarettes among high school students, or use of cigarettes, cigars, smokeless tobacco, pipe tobacco, or bidis among middle and high school students. In 2015, an estimated 4.7 million middle and high school students were current tobacco product users, and, therefore, continue to be exposed to harmful tobacco product constituents, including nicotine. Nicotine exposure during adolescence, a critical period for brain development, can cause addiction, might harm brain development, and could lead to sustained tobacco product use among youths. Comprehensive and sustained strategies are warranted to prevent and reduce the use of all tobacco products among U.S. youths.
吸烟是美国可预防疾病和死亡的主要原因;如果目前的吸烟率持续下去,预计今天在世的 560 万年龄<18 岁的美国人将因与吸烟有关的疾病而过早死亡。吸烟和成瘾主要发生在青少年和青年时期。疾病预防控制中心和食品药品监督管理局(FDA)分析了 2011-2015 年全国青少年烟草调查(NYTS)的数据,以确定美国中(6-8 年级)和高中(9-12 年级)学生目前(过去 30 天)使用七种烟草制品(香烟、雪茄、无烟烟草、电子烟[用于吸烟的水烟袋]、水烟管[用于吸烟的烟草水烟袋]、烟斗烟草和比迪烟[小进口卷烟包装在 tendu 叶])的流行率和趋势。2015 年,电子烟是中(5.3%)和高(16.0%)中学生中最常用的烟草制品。在 2011-2015 年期间,中学生和高中生中目前使用电子烟和水烟管的人数显著增加,而传统烟草制品(如香烟和雪茄)的使用率下降,导致整体烟草制品使用量没有变化。在 2014-2015 年期间,中学生中目前使用电子烟的人数增加,而高中生中目前使用水烟管的人数减少;相比之下,中学生中水烟管的使用率没有变化,高中生中电子烟的使用率也没有变化,中高中生使用香烟、雪茄、无烟烟草、烟斗烟草或比迪烟也没有变化。2015 年,估计有 470 万中学生和高中生是目前的烟草制品使用者,因此继续接触到有害的烟草制品成分,包括尼古丁。青少年时期(大脑发育的关键时期)接触尼古丁会导致成瘾,可能损害大脑发育,并导致青少年持续使用烟草制品。需要采取全面和持续的策略,防止和减少美国青少年使用所有烟草制品。
