To (i) estimate the prevalence of adolescent vaping in 47 lower-middle, upper-middle and high-income countries, and (ii) test the association between implementation of World Health Organisation (WHO) tobacco control policies and adolescent e-cigarette use (also known as vaping) in 44 countries where implementation data were available.
Cross-sectional surveys.
A total of 47 lower-middle, upper-middle and high-income countries.
A total of 151 960 adolescents (typically ages 13-15) who participated in WHO's Global Youth Tobacco Survey between 2015 and 2018.
Prevalence of past-30-day vaping and past 30-day frequent vaping (≥10 days) were estimated from the surveys. Data on the implementation of six tobacco control measures including monitoring, smoke-free policies, cessation programs, warning about the dangers of tobacco, advertising bans and taxation were taken from WHO's report on global tobacco epidemic.
The overall weighted prevalence of adolescent vaping and frequent vaping in the past 30 days was 8.6% (95% CI, 8.3-8.9) and 1.7% (95% CI, 1.6-1.8), respectively. For five of WHO's policies (monitoring, smoking-free environment, cessation programs, health warning and advertising bans), their association with adolescent vaping was inconclusive because of large variation of their effects across countries. Higher tax on combustible tobacco products was associated with higher adolescent vaping (> = 75% tax vs < 25% tax; odds ratio = 2.58; 95% CI, 1.25-5.21).
In 47 lower-middle, upper-middle and high-income countries from 2015 to 2018, ~1 in 12 (8.6%) adolescents reported vaping in the past 30 days, but prevalence of frequent vaping was low (1 in 60; 1.7%). A higher tobacco tax was associated with higher adolescent vaping.
(i) 估计 47 个中下等、中上收入和高收入国家青少年吸电子烟的流行率，以及 (ii) 在 44 个有实施数据的国家中检验世界卫生组织 (WHO) 烟草控制政策的实施与青少年电子烟使用（也称为吸电子烟）之间的关联。
横断面调查。
共 47 个中下等、中上收入和高收入国家。
2015 年至 2018 年间参加了 WHO 全球青年烟草调查的共 151960 名青少年（通常为 13-15 岁）。
从调查中估计过去 30 天吸电子烟和过去 30 天频繁吸电子烟（≥10 天）的流行率。WHO 全球烟草流行报告中获取了 6 项烟草控制措施的实施数据，包括监测、无烟政策、戒烟计划、烟草危害警告、广告禁令和税收。
青少年过去 30 天吸电子烟和频繁吸电子烟的总体加权流行率分别为 8.6%（95%CI，8.3-8.9）和 1.7%（95%CI，1.6-1.8）。对于 WHO 的 5 项政策（监测、无烟环境、戒烟计划、健康警告和广告禁令），由于各国之间效果的巨大差异，它们与青少年吸电子烟的关联尚无定论。对可燃烟草产品征收更高的税与青少年吸电子烟的比例更高有关（≥75%税 vs <25%税；比值比=2.58；95%CI，1.25-5.21）。
在 2015 年至 2018 年间的 47 个中下等、中上收入和高收入国家中，约 12 名青少年（8.6%）报告在过去 30 天内吸电子烟，但频繁吸电子烟的比例较低（1 名/60 名；1.7%）。较高的烟草税与青少年吸电子烟的比例更高有关。
