We aimed to assess the recent levels of knowledge and attitudes toward tobacco smoking among adolescents aged 12-16 years in 2010-2019, and to examine trends from 1999 to 2019.
We used the most recent data from 145 countries/territories (hereafter "countries") that conducted at least one Global Youth Tobacco Survey (GYTS) between 2010 and 2019 to assess the current levels of knowledge and attitudes toward tobacco smoking among adolescents aged 12-16 years. And 112 countries that conducted at least three GYTS surveys from 1999 to 2019 were used to assess the trends among adolescents aged 12-16 years over time.
Among 570,492 adolescents from 145 countries, 13.9% (95% , 11.9%-15.8%) incorrectly believed that tobacco smoking was not harmful, and 16.1% (95% , 15.2%-16.9%) believed that exposure to secondhand smoke was not harmful. A substantial proportion believed that quitting smoking was easy (42.5%; 95% , 36.9%-48.0%) or that short-term smoking was safe if followed by quitting (40.2%; 95% , 39.1%-41.3%). Additionally, 25.8% (95% , 24.8%-26.8%) believed that tobacco smoking helps young people feel more comfortable, 26.4% (95% , 24.8%-28.0%) believed that it helps them make more friends, and 15.8% (95% , 14.6%-17.0%) believed that it makes them appear more attractive. Among 1,734,258 adolescents from 112 countries, 67.9% of countries showed increasing or stable trends in the belief that smoking is not harmful, 75.9% for the belief that secondhand smoke exposure is not harmful, 38.4% for short-term smoking being safe, 32.1% for quitting being easy, and 69.6, 43.8, and 44.6% for the beliefs that smoking helps with comfort, making friends, and appearing attractive, respectively, from 1999 to 2019.
Incorrect beliefs and positive attitudes toward tobacco smoking were prevalent among adolescents worldwide. Moreover, these beliefs and attitudes toward tobacco smoking have either persisted or increased in most included countries over time. Targeted interventions and policies are needed to reduce these and promote accurate knowledge about tobacco use and its harmful effects.
我们旨在评估2010 - 2019年12至16岁青少年对吸烟的最新知识水平和态度，并研究1999年至2019年的趋势。
我们使用了145个国家/地区（以下简称“国家”）的最新数据，这些国家在2010年至2019年期间至少进行了一次全球青少年烟草调查（GYTS），以评估12至16岁青少年对吸烟的当前知识水平和态度。并且使用了112个在1999年至2019年期间至少进行了三次GYTS调查的国家，来评估12至16岁青少年随时间的趋势。
在来自145个国家的570,492名青少年中，13.9%（95% ，11.9% - 15.8%）错误地认为吸烟无害，16.1%（95% ，15.2% - 16.9%）认为接触二手烟无害。很大一部分人认为戒烟容易（42.5%；95% ，36.9% - 48.0%），或者认为短期吸烟后再戒烟是安全的（40.2%；95% ，39.1% - 41.3%）。此外，25.8%（95% ，24.8% - 26.8%）认为吸烟能帮助年轻人感觉更舒适，26.4%（95% ，24.8% - 28.0%）认为能帮助他们交到更多朋友，15.8%（95% ，14.6% - 17.0%）认为能让他们看起来更有吸引力。在来自112个国家的1,734,
