这项调查研究提供了具有全国代表性的青少年尼古丁电子烟最新趋势估计，电子烟危害的感知风险，电子烟材料的可及性，以及特定电子烟品牌和口味的使用趋势。重要性美国青少年尼古丁电子烟在2017年至2019年期间以创纪录的速度增长，促使新的国家政策减少青少年首选电子烟产品的口味。目的评估2017年至2020年美国青少年尼古丁电子烟产品的流行率、感知危害和可及性。设计，设置和参与者这项调查研究包括来自监测未来的数据，该数据从2017年到2020年对10年级和12年级的学生（结果汇总年级，n = 94 320）进行了年度，跨部门，以学校为基础的全国代表性调查。主要结果和措施自我报告的尼古丁vaping的流行率;最常使用的vaping品牌和风味;尼古丁vaping的感知风险;以及感知获得vaping设备，vaping尼古丁溶液和调味溶液的容易程度。结果2020年，监测未来调查了10年级和12年级的8660名学生，其中50.6%（95% CI，47%-54%）为女性，13%（95% CI，8%-21%）为非西班牙裔黑人，29%（95% CI，21%-40%）为西班牙裔，53%（95% CI，42%-63%）为非西班牙裔白色人。2020年，过去30天使用尼古丁蒸汽烟的患病率为22%（95% CI，19%-25%），过去12个月使用的患病率为32%（95% CI，28%-37%），终身使用的患病率为41%（95% CI，37%-46%）;这些水平与2019年相比没有显著变化。在2019年至2020年期间，每日尼古丁电子烟（过去30天中>= 20天使用）从9%（95%CI，8%-10%）显著下降至7%（95%CI，6%-9%）。JUUL品牌在过去30天的使用率从2019年的20%（95%CI，18%-22%）下降到2020年的13%（95%CI，11%-15%），而其他品牌的使用率则有所增加。在2020年过去30天内使用电子烟的年轻人中，最常使用的口味是水果，占59%（95% CI，55%-63%），其次是薄荷，27%（95% CI，24%-30%）和薄荷醇7%（95% CI，5%-9%）;与2019年相比，报告容易获得电子烟设备和尼古丁溶液的人数明显减少; 80%（95%CI，75%-84%）的人报告说，他们可以很容易地得到烟草或薄荷醇以外的电子烟味道。在所有年轻人中，从2019年到2020年，偶尔和定期使用尼古丁电子烟的风险都有所增加。从2017年到2019年，美国青少年尼古丁电子烟的增长趋势在2020年停止，包括每日电子烟的下降。从2019年到2020年，一些电子烟产品的感知可及性下降，以及尼古丁电子烟的感知风险增加。然而，青少年尼古丁电子烟仍然非常普遍，口味仍然很容易获得，JUUL使用率的下降被其他品牌的使用率增加所抵消。问题2017年至2020年美国青少年尼古丁电子烟的流行趋势如何？在这项对8660名10年级和12年级学生的调查研究中，2017年至2019年青少年电子烟的增加在2020年停止。JUUL品牌使用量的显著下降被其他电子烟品牌使用量的显著增加所抵消。这意味着青少年尼古丁vaping仍然非常普遍，这项研究发现，22%的青少年在2020年的过去30天内吸食尼古丁。
This survey study presents nationally representative estimates of recent trends in adolescent nicotine vaping, perceived risk of harm from vaping, accessibility of vaping materials, as well as trends in use of specific vaping brands and flavors.Importance US adolescent nicotine vaping increased at a record pace from 2017 to 2019, prompting new national policies to reduce access to flavors of vaping products preferred by youth. Objective To estimate prevalence, perceived harm, and accessibility of nicotine vaping products among US adolescents from 2017 to 2020. Design, Setting, and Participants This survey study includes data from Monitoring the Future, which conducted annual, cross-sectional, school-based, nationally representative surveys from 2017 to 2020 of 10th- and 12th-grade students (results pooled grades, n = 94 320) about vaping and other topics. Main Outcomes and Measures Prevalence of self-reported nicotine vaping; vaping brand and flavor used most often; perceived risk of nicotine vaping; and perceived ease of getting vaping devices, nicotine solutions for vaping, and flavored solutions. Results In 2020, Monitoring the Future surveyed 8660 students in 10th and 12th grade, of whom 50.6% (95% CI, 47%-54%) were female, 13% (95% CI, 8%-21%) were non-Hispanic Black, 29% (95% CI, 21%-40%) were Hispanic, and 53% (95% CI, 42%-63%) were non-Hispanic White. Nicotine vaping prevalence in 2020 was 22% (95% CI, 19%-25%) for past 30-day use, 32% (95% CI, 28%-37%) for past 12-month use, and 41% (95% CI, 37%-46%) for lifetime use; these levels did not significantly change from 2019. Daily nicotine vaping (use on >= 20 days of the last 30 days) significantly declined from 9% (95% CI, 8%-10%) to 7% (95% CI, 6%-9%) over 2019 to 2020. JUUL brand prevalence in the past 30 days decreased from 20% (95% CI, 18%-22%) in 2019 to 13% (95% CI, 11%-15%) in 2020, while use of other brands increased. Among youth who vaped in the past 30 days in 2020, the most often used flavor was fruit at 59% (95% CI, 55%-63%), followed by mint at 27% (95% CI, 24%-30%) and menthol at 7% (95% CI, 5%-9%); significantly fewer reported easy access to vaping devices and nicotine solutions compared with 2019; and 80% (95% CI, 75%-84%) reported they could easily get a vaping flavor other than tobacco or menthol. Among all youth, perceived risk of both occasional and regular nicotine vaping increased from 2019 to 2020. Conclusions and Relevance Increasing US adolescent nicotine vaping trends from 2017 to 2019 halted in 2020, including a decline in daily vaping. Decreases in perceived accessibility of some vaping products, as well as increases in perceived risk of nicotine vaping, occurred from 2019 to 2020. Yet, adolescent nicotine vaping remains highly prevalent, flavors remain highly accessible, and declines in JUUL use were countered by increased use of other brands.Question How has nicotine vaping prevalence trended among US adolescents from 2017 to 2020? Findings In this survey study of 8660 10th- and 12th-grade students, increases in teenage vaping from 2017 to 2019 halted in 2020. Significant declines in use of the JUUL brand were countered by significant increases in use of other vaping brands. Meaning Adolescent nicotine vaping remains highly prevalent, and this study found that 22% of teenagers vaped nicotine in the past 30 days in 2020.
