The Effect of Prices on Cigarette Use Among Youths in the Global Youth Tobacco Survey
ABSTRACT INTRODUCTION: We estimate the impact of cigarette prices on youth smoking in 38 countries of the Global Youth Tobacco Survey. METHODS: We use a 2-part model of cigarette demand. In the first part, we estimate the impact of prices on the decision to smoke. Conditional on smoking, we then estimate the effect of price on the number of cigarettes smoked. We employ 2-way fixed effects to address country-level time-invariant heterogeneity and control for an array of local-level variables to address local-level heterogeneity. RESULTS: The estimated total price elasticity is -1.5 for a sample that contains both high-income and low- and middle-income countries. Constraining the sample to only low- and middle-income countries, we find a total price elasticity of -2.2, suggesting that smoking among youths in low-income countries is more responsive to cigarette price changes. CONCLUSION: Cigarette price increases are highly effective in reducing smoking prevalence and consumption among youths globally, and particularly among youths in low- and middle-income countries.

ABSTRACT: This study examines lowest cigarette prices in all tobacco retail outlets in Washington D.C. (n=750) in relation to the type and number of high schools nearby, controlling for confounders. The lowest overall and Newport menthol prices were significantly lower at outlets near public non-charter and charter schools compared with outlets near private schools. Given higher smoking prevalence and more price-sensitive youth subgroups in U.S. public schools, exposure to low prices may contribute to tobacco-related health disparities in minority and low-income populations. Tobacco taxes combined with policies to minimize the increasing use of price as a marketing tool are critical.Health & Place 01/2015; 31. DOI:10.1016/j.healthplace.2014.12.002 · 2.44 Impact Factor

ABSTRACT: Evidence on the relationship between cigarette prices and adult smoking in low- and middle-income countries (LMICs) is relatively limited. This study offers new descriptive evidence on this relationship using data from a set of 13 LMICs. We use Global Adult Tobacco Survey (GATS) cross-country data from approximately 200,000 participants aged 15 and older. Estimates on the relationship between prices and adult smoking were obtained from logit models of smoking participation and ordinary least squares models of conditional cigarette demand. Higher prices were associated with lower demand across countries, in terms of both smoking prevalence and daily number of cigarettes smoked among smokers. Our estimates suggest that the total price elasticity of cigarette demand in LMICs is approximately -0.53. We find that higher socioeconomic status (SES), represented through wealth and education effects is associated with lower chance of smoking overall, but among existing smokers, it may be associated with a larger number of cigarettes smoked. After controlling for a set of individual demographic and country characteristics, cigarette prices retain a significant role in shaping cigarette demand across LMICs. Because higher SES is associated with a reduced chance of smoking overall but also with increased daily consumption among current smokers, optimal tobacco tax policies in LMICs may face an added need to accommodate to shifting SES structures within the populations of these countries.Nicotine & Tobacco Research 01/2014; 16 Suppl 1:S10-5.

ABSTRACT: Purpose Sound public health policy is based on relevant and timely information. A brief review of the history of youth tobacco control illustrates the central role of epidemiology to inform policy choices and evaluate their consequences. Methods A narrative review was conducted. Results Epidemiologic studies have shown that most smokers begin as adolescents or young adults and individuals who reach their mid-twenties as non-smokers are unlikely to ever become smokers. This key recognition made it clear that long-term tobacco control must prevent initiation of smoking among youth. Over time, tobacco use prevention interventions have evolved, increasing in reach and effectiveness as they moved from initially focusing on the individual to an approach that targets both populations and communities. Effective interventions for preventing youth smoking include raising tobacco prices, clean indoor air laws, and intensive mass media campaigns. Conclusions Great strides have been made in youth tobacco control but 18% of high school students continue to smoke. It is up to epidemiologists, fellow scientists, practitioners, and advocates to assure that strategies that are known to work are fully implemented as well as to continue to find more successful solutions that can further lower the incidence of youth smoking initiation and can address new tobacco products and changing contexts.Annals of Epidemiology 04/2014; DOI:10.1016/j.annepidem.2014.03.005 · 2.15 Impact Factor
