Lung-Chang Chien (Environmental and Occupational Health) co-authored "Geospatial Associations Between Tobacco Retail Outlets and Current Use of Cigarettes and e-Cigarettes among Youths in Texas," which has been published in the Journal of Biometrics and Biostatistics. The study analyzed students in grades 6, 8 and 10 from selected schools in four Texas counties from 2014-15 and the presence of at least one tobacco retail outlets (TRO) within half a mile of the school. The study 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. The result provides evidence of the influence of TRO on smoking prevalence among students, and reveals potential high-risk areas. The finding can help interventions carried out in schools located in potential high-risk areas.
