Objective: To describe the prevalence and change in prevalence of electronic nicotine delivery systems (ENDS) use in youth by country and combustible smoking status. Methods: Databases and the grey literature were systematically searched to December 2015. Studies describing the prevalence of ENDS use in the general population aged ≤20 years in a defined geographical region were included. Where multiple estimates were available within countries, prevalence estimates of ENDS use were pooled for each country separately. Results: Data from 27 publications (36 surveys) from 13 countries were included. The prevalence of ENDS ever use in 2013–2015 among youth were highest in Poland (62.1%; 95%CI: 59.9–64.2%), and lowest in Italy (5.9%; 95%CI: 3.3–9.2%). Among non‐smoking youth, the prevalence of ENDS ever use in 2013–2015 varied, ranging from 4.2% (95%CI: 3.8–4.6%) in the US to 14.0% in New Zealand (95%CI: 12.7–15.4%). The prevalence of ENDS ever use among current tobacco smoking youth was the highest in Canada (71.9%, 95%CI: 70.9–72.8%) and lowest in Italy (29.9%, 95%CI: 18.5–42.5%). Between 2008 and 2015, ENDS ever use among youth increased in Poland, Korea, New Zealand and the US; decreased in Italy and Canada; and remained stable in the UK. Conclusions: There is considerable heterogeneity in ENDS use among youth globally across countries and also between current smokers and non‐smokers. Implications for public health: Population‐level survey data on ENDS use is needed to inform public health policy and messaging globally.
