E-cigarettes are a popular mode of delivery for nicotine, tobacco and cannabis. The prevalence of vaping among youth is increasing and this review aims to identify features of the neighbourhood environment, e.g., retailers, advertisements, and policies, that are associated with youth vaping. We included 48 studies. Of these, approximately 40% and 60% reported that presence of e-cigarette retailers, and advertisements, was associated with statistically higher odds of e-cigarette use in youth, respectively. Approximately 30% of studies reported that policies affecting e-cigarette availability were associated with statistically lower odds of vaping. Identifying these influential features of the neighbourhood environment will help formulate appropriate policies to reduce e-cigarette use among youth. • E-cigarettes are a popular mode of delivery for nicotine, tobacco and cannabis and prevalence of vaping among youth is increasing. • This review identifies features of the neighbourhood environment, e.g., retailers, advertisements, and policies, that are associated with vaping among youth. • Approximately 40% of included studies reported that interaction with e-cigarette retailers, was associated with statistically higher odds of e-cigarette use in youth. • Approximately 60% of included studies reported that interaction with e-cigarette advertisements was associated with statistically higher odds of e-cigarette use in youth,. • Approximately 30% of studies reported that policies affecting e-cigarette availability were associated with statistically lower odds of vaping. • More research with objective measures is needed, and identifying influential elements of the neighbourhood environment will help formulate appropriate policies to reduce e-cigarette use among youth.

Exposure assessment in the context of mobility-oriented health research often is challenged by the type of spatial measurement technique used to estimate exposures to environmental features. The purpose of this study is to compare smartphone global positioning system (GPS), shortest network path mobility, and buffer-based approaches in estimating exposure to outdoor food and beverage advertising among a sample of 154 teenagers involved in the SmartAPPetite study during 2018 in London, Ontario, Canada. Participants were asked to report their home postal code, age, gender identity, ethnicity, and number of purchases they had made at a retail food outlet in the past month. During the same time period, a mobile phone application was used to log their mobility and specifically record when a participant was in close proximity to outdoor advertising. The results of negative binomial regression modelling reveal significant differences in estimates of advertising exposure, and the relationship to self-reported purchasing. Spatial exposure estimation methods showed differences across regression models, with the buffer and observed GPS approaches delivering the best fitting models, depending on the type of retail food outlet. There is a clear need for more robust research of spatial exposure measurement techniques in the context of mobility and food (information) environment research. • Exposure to outdoor food and beverage advertising has little association with purchasing among adolescents. • Comparison of GPS, network paths, and residential buffers in measuring exposure to outdoor food and beverage advertising. • Residential buffers and GPS delivered the best-fitting models, dependent on the type of retail food outlet under study.
