从2002年到2018年，在成年早期（18-23岁）和青春期（18岁以下）开始吸烟的吸烟者比例是否有所增加？在这项包括71756名年龄在22岁至23岁的年轻人的重复横断面研究中，从2002年到2018年，在成年早期开始吸烟的曾经吸烟者的比例增加了一倍多，从成年早期过渡到每天吸烟的人的比例也从2002年的38.7%增加到2018年的55.9%。这些发现表明，预防吸烟的努力通常以青少年为目标，应该扩大到年轻人，他们占新吸烟者的比例越来越大。本横断面研究评估了2002年至2018年早期成人（18-23岁）与青少年（年龄<18岁）开始吸烟和向日常吸烟过渡的趋势。成功地降低青少年吸烟率可以反映完全预防开始吸烟或将开始吸烟的年龄从青春期转移到成年早期。评估2002年至2018年早期成人（18-23岁）与青少年（18岁以下）开始吸烟和向日常吸烟过渡的趋势。开始吸烟的年龄和向每日吸烟过渡的年龄是由全国药物使用和健康调查（2002-2018）确定的，这是一项代表美国人口的年度、基于人群的重复横断面研究。本横断面分析仅限于2002年至2018年调查期间年龄在22至23岁之间完成调查的年轻人，以限制潜在的年龄相关回忆偏倚。对曾经吸烟者中开始吸烟的年龄进行回顾性评估；评估每日吸烟者向每日吸烟过渡的年龄。数据分析时间为2019年6月至2020年7月。调查日历年（2002 - 2018）。主要结局是人口加权吸烟率、青少年（年龄<18岁）和成年早期（年龄18-23岁）开始吸烟和向日常吸烟过渡。在71756名22至23岁的年轻人（38 226名女性[50.5%]）中，曾经吸烟的患病率从2002年的人口加权估计值74.6% （95% CI, 73.1%-75.9%）下降到2018年的51.4% (95% CI, 49.3%-53.5%) （P < 0.001）。日吸烟率同样从2002年的41.1% （95% CI, 39.1%-43.1%）下降到2018年的20.2% (95% CI, 18.6%-21.8%) （P < 0.001）。然而，在48015名曾经吸烟者中，在成年早期（18-23岁）开始吸烟的比例在此期间从2002年的20.6% （95% CI, 18.5%-22.8%）增加到2018年的42.6% (95% CI, 39.6%-45.7%) （P < 0.001）。同样，在24490名日常吸烟者中，成年早期过渡到日常吸烟的比例从2002年的38.7% （95% CI, 35.9%-41.6%）增加到2018年的55.9% (95% CI, 52.0%-59.8%) （P < 0.001）。开始吸烟者和大多数新的日常吸烟者中有很大一部分现在是年轻人，反映了从青春期到成年早期的转变，这一人群曾被认为超过了开始吸烟的关键危险期。有必要扩大长期以来对青少年监测和预防的重视，使其包括青年人口。
Has the proportion of cigarette smokers initiating smoking in early adulthood (ages 18-23 years) vs adolescence (age <18 years) increased from 2002 to 2018? In this repeated cross-sectional study including 71 756 young adults aged 22 to 23 years, the proportion of ever smokers who initiated cigarette smoking in early adulthood more than doubled between 2002 and 2018, and the proportion of daily cigarette smokers who transitioned to daily smoking in early adulthood also increased from 38.7% in 2002 to 55.9% in 2018. These findings suggest that smoking prevention efforts typically targeting adolescents should be expanded to address young adults, who account for an increasing and substantial proportion of new smokers. This cross-sectional study assesses trends in early adult (ages 18-23 years) vs adolescent (age <18 years) cigarette smoking initiation and transition to daily cigarette smoking from 2002 to 2018. Success in reducing the prevalence of adolescent smoking could reflect complete prevention of smoking initiation or a shift in the age of cigarette smoking initiation from adolescence into early adulthood. To assess trends in early adult (ages 18-23 years) vs adolescent (age <18 years) cigarette smoking initiation and transition to daily cigarette smoking from 2002 to 2018. Ages at initiation of smoking and the transition to daily smoking were ascertained from the National Survey on Drug Use and Health (2002-2018), an annual, population-based, repeated cross-sectional study representative of the US population. This cross-sectional analysis was restricted to young adults who completed the survey at ages 22 to 23 years during survey years 2002 to 2018 to limit potential age-related recall bias. Retrospectively collected age of cigarette smoking initiation was assessed among ever cigarette smokers; age of transition to daily smoking was assessed among ever daily cigarette smokers. Data analysis was performed from June 2019 to July 2020. Calendar year of survey (2002 to 2018). The main outcomes were population-weighted cigarette smoking prevalence and cigarette smoking initiation and transition to daily smoking in adolescence (age <18 years) vs early adulthood (ages 18-23 years). Among 71 756 young adults aged 22 to 23 years (38 226 women [50.5%]), ever cigarette smoking prevalence decreased from a population-weighted estimate of 74.6% (95% CI, 73.1%-75.9%) in 2002 to 51.4% (95% CI, 49.3%-53.5%) in 2018 (P < .001). Daily smoking prevalence rates similarly decreased from 41.1% (95% CI, 39.1%-43.1%) in 2002 to 20.2% (95% CI, 18.6%-21.8%) in 2018 (P < .001). However, among 48 015 ever smokers, the proportion initiating smoking in early adulthood (ages 18-23 years) increased over this time, from 20.6% (95% CI, 18.5%-22.8%) in 2002 to 42.6% (95% CI, 39.6%-45.7%) in 2018 (P < .001). Similarly, among 24 490 daily cigarette smokers, the proportion who transitioned to daily smoking in early adulthood increased from 38.7% (95% CI, 35.9%-41.6%) in 2002 to 55.9% (95% CI, 52.0%-59.8%) in 2018 (P < .001). A substantial proportion of beginning smokers and most new daily smokers are now young adults, reflecting a shift from adolescence to early adulthood, a population segment once considered beyond the critical risk period for cigarette smoking onset. Expanding the long-standing emphasis on adolescent surveillance and prevention in adolescence to include the young adult population is warranted.
