Abstract
IntroductionTo identify the geospatial association between the presence of tobacco retail outlets (TRO) around schools’ neighborhoods, and current use of cigarettes and e-cigarettes among adolescents in four counties in Texas.MethodsStudents in grades 6, 8 and 10th were surveyed in their schools in 2014–2015. The schools’ addresses was geocoded to determine the presence of at least one TRO within half a mile of the school. Two outcomes were considered: past 30-day use of (a) cigarettes and (b) e-cigarettes. Bayesian structured additive regression models and Kriging methods were used to estimate the geospatial associations between the presence of TRO and use in three counties: Dallas/Tarrant, Harris, and Travis.ResultsWe observed a geospatial association between the presence of TRO around the schools and current use of cigarettes in the eastern area of Dallas County and in the southeastern area of Harris County. Also, a geospatial association between the presence of TRO around the schools and current use of e-cigarettes was observed in the entire Tarrant County and in the northeastern area of Harris County.ConclusionsThere were geospatial associations between the presence of TRO around some schools and cigarette/e-cigarette use among students, but this association was not consistent across all the counties. More research is needed to determine why some areas are at higher risk for this association.

Summary
To identify the geospatial association between the presence of tobacco retail outlets (TRO) around schools’ neighborhoods, and current use of cigarettes and e-cigarettes among adolescents in four counties in Texas. Several studies have examined the prevalence of cigarette and e-cigarette use in the U.S The Population Assessment of Tobacco and Health (PATH) study in 2013–2014 assessed a representative sample of youth 12–17 years old in the U.S [6,7]. PATH reported that while 13.4% and 10.7% were ever users of cigarettes and e-cigarettes, respectively, 4.6% and 3.1% of participants were past 30-day users. During the academic year of 2014– 2015, the Texas Adolescent Tobacco and Marketing Surveillance System (TATAMS) examined a representative sample of students enrolled in 6th, 8th and 10th grades [8]. TATAMS reported that 10.9% and 19.5% were ever users while 3.5% and 7.4% were past 30-day users of cigarettes and e-cigarettes respectively. TATAMS had a higher prevalence of current use of cigarette (5.3%) and e-cigarette (10.6%) than PATH after the age-standardization to the PATH population
