Searches were not limited by date, language, country or peer-reviewed status.Study selection After screening for quality, studies that examined the relationship between tobacco outlet density and adolescents’ past-month smoking were selected for inclusion.Data extraction Two investigators screened study abstracts and full texts and independently extracted data. Consensus was reached at each stage.Data synthesis Random-effects meta-analyses were conducted on 11 studies that provided 13 effect sizes. Results showed that there was a significant association between tobacco outlet density around homes and adolescents’ past-month smoking behaviour, with an overall effect size of OR=1.08 (95% CI 1.04 to 1.13; P<0.001; I2=0%). For density around schools, the association was not statistically significant (OR=1.01, 95% CI 0.98 to 1.03; P=0.53; I2=39%).Conclusions These findings suggest that exposure to tobacco outlets near home environments may be important for understanding adolescents’ past-month smoking. Restricting access to tobacco outlets and controlling the number of outlets in residential areas may be an effective preventive strategy to help reduce adolescents’ smoking. %U https://tobaccocontrol.bmj.com/content/tobaccocontrol/early/2018/03/08/tobaccocontrol-2017-054065.full.pdf
