Background

Tobacco use is a leading preventable cause of morbidity and mortality worldwide. Little is known about recent prevalence and trends in tobacco use among adolescents globally. We aimed to assess the recent global prevalence of tobacco use in young adolescents and the secular trends in prevalence between 1999 and 2018.

Methods

We used the most recent Global Youth Tobacco Surveys data on adolescents aged 13–15 years from 143 countries or territories that had done at least one survey between Jan 1, 2010, and Dec 31, 2018, to assess the recent prevalence of tobacco use; and data from 140 countries that had done two or more surveys between Jan 1, 1999, and Dec 31, 2018, to assess the trends in the prevalence of tobacco use.

Findings

530 234 adolescents were included from the 143 countries that had done at least one survey between 2010 and 2018. 1 192 312 adolescents were included from the 140 countries that had done two or more surveys between 1999 and 2018. The most recent global prevalence of cigarette smoking was 11·3% (95% CI 10·3–12·3) in boys and 6·1% (5·6–6·6) in girls, based on cigarette smoking on at least 1 day during the past 30 days, 6·0% (5·5–6·6) and 2·6% (2·4–2·9) based on smoking on at least 3 days, and 4·2% (3·8–4·6) and 1·6% (1·4–1·8) based on smoking on at least 6 days. The most recent prevalence of the use of tobacco products other than cigarettes (eg, chewing tobacco, snuff, dip, cigars, cigarillos, pipe, electronic cigarettes) on at least 1 day during the past 30 days was 11·2% (9·9–12·6) in boys and 7·0% (6·4–7·7) in girls. The most recent prevalence of any tobacco use on at least 1 day during the past 30 days was 17·9% (16·1–19·6) in boys and 11·5% (10·5–12·4) in girls. The prevalence of cigarette smoking on at least 1 day during the past 30 days decreased between the first and last surveys in 80 (57·1%) of 140 countries, was unchanged in 39 countries (27·9%), and increased in 21 countries (15·0%). However, the prevalence of the use of tobacco products other than cigarettes was unchanged or increased in 81 (59·1%) of 137 countries.

Interpretation

The global prevalence of tobacco use among adolescents aged 13–15 years was substantial. Although the prevalence of cigarette smoking decreased over time in the majority of countries, the prevalence of the use of other tobacco products increased or did not change in the majority of countries during the past two decades. These findings re-emphasise the need to strengthen tobacco control efforts among young adolescents globally.

1999-2018年，143个国家的13-15岁青少年中烟草使用的流行率和趋势：全球青年烟草调查的结果

背景

吸烟是世界范围内发病率和死亡率的主要可预防原因。对于全球青少年中最近的烟草使用率和趋势知之甚少。我们的目标是评估1999年至2018年之间全球青少年吸烟的最新流行率以及流行趋势的长期趋势。

方法

我们使用了来自143个国家或地区的13至15岁青少年的最新全球青年烟草调查数据，这些数据在2010年1月1日至2018年12月31日期间进行了至少一项调查，以评估最近的烟草使用率；以及来自140个国家/地区的数据，这些国家/地区在1999年1月1日至2018年12月31日期间进行了两次或更多次调查，以评估烟草使用流行趋势。

发现

来自143个国家/地区的530234名青少年在2010年至2018年之间进行了至少一项调查。包括来自140个国家/地区的1192312名青少年，这些国家在1999年至2018年之间进行了两次或多次调查。根据过去30天内至少1天的吸烟情况，男孩的吸烟率为11·3％（95％CI 10·3–12·3），女孩的为6·1％（5·6–6·6）天，基于至少三天的吸烟量，分别有6·0％（5·5–6·6）和2·6％（2·4–2·9），还有4·2％（3·8–4· 6）和至少吸烟6天后吸烟的1·6％（1·4-1–8）。在过去30天内，至少有1天最近使用除香烟以外的烟草产品（例如咀嚼烟草，鼻烟，蘸水，雪茄，小雪茄，烟斗，电子烟）的流行率为11·2％（9·男孩为9–12·6），女孩为7·0％（6·4–7·7）。在过去30天内，至少1天吸烟的最新流行率是男孩为17·9％（16·1–19·6），女孩为11·5％（10·5–12·4） 。在140个国家中的80个（57·1％）的首次调查和最后一次调查之间，过去30天中至少1天的吸烟率下降了，在39个国家（27·9％）中没有变化，而在21个国家中上升了21个国家（15·0％）。但是，在137个国家中，有81个国家（59·1％）使用了除卷烟以外的烟草产品的流行率没有变化或上升。在21个国家/地区有所增加（15·0％）。但是，在137个国家中，有81个国家（59·1％）使用了除卷烟以外的烟草产品的流行率没有变化或上升。在21个国家/地区有所增加（15·0％）。但是，在137个国家中，有81个国家（59·1％）使用了除卷烟以外的烟草产品的流行率没有变化或上升。

解释

全球13至15岁青少年吸烟的流行率很高。尽管在大多数国家中，吸烟的流行率随时间而下降，但在过去的二十年中，大多数国家中使用其他烟草产品的流行率增加了或没有改变。这些发现再次强调了在全球范围内加强青少年控制烟草工作的必要性。
