The use of tobacco products during adolescence increases the risk for adverse health effects and lifelong nicotine addiction. In 2014, an estimated 4.6 million middle and high school students were current users of any tobacco product, of whom an estimated 2.2 million were current users of two or more types of tobacco products. Symptoms of nicotine dependence are increased for multiple tobacco product users compared with single-product users. CDC and the Food and Drug Administration (FDA) analyzed data from the 2014 National Youth Tobacco Survey (NYTS) to determine how frequently (the number of days in the preceding 30 days) U.S. middle school (grades 6–8) and high school (grades 9–12) students used cigarettes, e-cigarettes, cigars, and smokeless tobacco products. Among current users (≥1 day during the preceding 30 days) in high school, frequent use (≥20 days during the preceding 30 days) was most prevalent among smokeless tobacco users (42.0%), followed by cigarette smokers (31.6%), e-cigarette users (15.5%), and cigar smokers (13.1%); a similar pattern was observed for those who used during all 30 days. Among current users in middle school, frequent use was greatest among smokeless tobacco users (29.2%), followed by cigarette smokers (20.0%), cigar smokers (13.2%) and e-cigarette users (11.8%). Current use of two or more types of tobacco products was common, even among students who used tobacco products 1–5 days during the preceding 30 days: 77.3% for cigar smokers, 76.9% for cigarette smokers, 63.4% for smokeless tobacco users, and 54.8% for e-cigarettes users. Preventing youths from initiating the use of any tobacco product is important to tobacco use prevention and control strategies in the United States. Monitoring the frequency and patterns of tobacco use among youths, including the use of two or more tobacco products, is important to inform evidence-based interventions to prevent and reduce all forms of tobacco use among youths.
青少年使用烟草制品会增加不良健康后果和终生尼古丁成瘾的风险。2014 年,估计有 460 万中学生和高中生是任何烟草制品的当前使用者,其中估计有 220 万是两种或两种以上类型烟草制品的当前使用者。与单一产品使用者相比,多产品使用者出现尼古丁依赖症状的频率更高。美国疾病控制与预防中心(CDC)和食品药品监督管理局(FDA)分析了 2014 年全国青少年烟草调查(NYTS)的数据,以确定美国中学生(6-8 年级)和高中生(9-12 年级)使用香烟、电子烟、雪茄和无烟烟草制品的频率(在过去 30 天内的天数)。在高中的当前使用者(≥过去 30 天内的 1 天)中,在过去 30 天内经常使用(≥20 天)的情况在无烟烟草使用者中最为普遍(42.0%),其次是香烟吸烟者(31.6%)、电子烟使用者(15.5%)和雪茄吸烟者(13.1%);在过去 30 天内所有时间都使用的人中也观察到了类似的模式。在中学生中的当前使用者中,经常使用的是无烟烟草使用者(29.2%),其次是香烟吸烟者(20.0%)、雪茄吸烟者(13.2%)和电子烟使用者(11.8%)。即使在过去 30 天内使用烟草制品 1-5 天的学生中,同时使用两种或两种以上类型的烟草制品也很常见:雪茄吸烟者占 77.3%,香烟吸烟者占 76.9%,无烟烟草使用者占 63.4%,电子烟使用者占 54.8%。防止青少年开始使用任何烟草制品对于美国的烟草使用预防和控制策略非常重要。监测青少年包括使用两种或两种以上烟草制品在内的烟草使用频率和模式,对于制定基于证据的干预措施以预防和减少青少年的所有形式的烟草使用非常重要。
