  • Is the cigarette price effect nonlinear?

    This poster will explore whether the impact of cigarette price on cigarette sale and consumption changes as the price level increase. We will use a variety of models, statistical methods and data sources to detect the potential nonlinear price impact.

  • Knowledge and beliefs about electronic cigarettes among quitline cessation staff

    Introduction Smokers are asking health practitioners for guidance about using e-cigarettes as an aid to quitting. Several studies have surveyed physicians. However, in North America many smokers seek help from telephone quitlines rather than physicians. The objective of the current study was to assess quitline counselors’ perceptions of e-cigarettes and what they tell callers about these products. Methods An online cross-sectional survey, conducted in 2014 with 418 quitline counselors in the U.S. and Canada, measured perceptions of e-cigarettes: (1) use as a quitting aid; (2) safety; (3) professional guidance given and organizational guidance received; (4) regulation. The response rate was 90.1%. Analyses included calculating standard errors and 95% confidence intervals around summary statistics. Results Nearly 70% of counselors believed that e-cigarettes are not effective quitting aids. Most believed e-cigarettes are addictive (87%) and that secondhand exposure to vapor is harmful (71%). Counselors reported that callers ask for advice about e-cigarettes, but few counselors recommended e-cigarettes (4%). Counselors (97%) reported being instructed by quitline employers to explain to clients that e-cigarettes are not FDA-approved; 74% were told to recommend approved quitting aids instead. Most counselors (> 87%) believed e-cigarettes should be regulated like cigarettes in terms of advertising, taxation, access by minors, and use in public places. Conclusions Quitline counselors view e-cigarettes as ineffective quitting aids, potentially dangerous, and in need of greater regulations. Counselors can influence how treatment seekers view e-cigarettes, therefore it is imperative that quitlines stay abreast of emerging data and communicate about these products in ways that best serve clients.

  • Logistic regression with multiple random effects: A simulation study of estimation methods and statistical packages.

    Several statistical packages are capable of estimating generalized linear mixed models and these packages provide one or more of three estimation methods: penalized quasi-likelihood, Laplace, and Gauss-Hermite. Many studies have investigated these methods' performance for the mixed-effects logistic regression model. However, the authors focused on models with one or two random effects and assumed a simple covariance structure between them, which may not be realistic. When there are multiple correlated random effects in a model, the computation becomes intensive, and often an algorithm fails to converge. Moreover, in our analysis of smoking status and exposure to anti-tobacco advertisements, we have observed that when a model included multiple random effects, parameter estimates varied considerably from one statistical package to another even when using the same estimation method. This article presents a comprehensive review of the advantages and disadvantages of each estimation method. In addition, we compare the performances of the three methods across statistical packages via simulation, which involves two- and three-level logistic regression models with at least three correlated random effects. We apply our findings to a real dataset. Our results suggest that two packages-SAS GLIMMIX Laplace and SuperMix Gaussian quadrature-perform well in terms of accuracy, precision, convergence rates, and computing speed. We also discuss the strengths and weaknesses of the two packages in regard to sample sizes.

  • Master Settlement Agreement Compliance Tobacco Directories: A Tool to Track Tribally Manufactured Cigarettes

    To our knowledge, no research has been conducted utilizing the MSA Compliance Tobacco Directories. In July 2014, the latest Tobacco Directories were identified for 43 states and the District of Columbia. Colorado archival tobacco directories were extracted since 2003 for case study analysis. Tribal manufacturers and brands were identified in the directories, and mapped by state using ArcGIS 10.2 software. Analysis of Tobacco Directories offers an innovative approach to help inform regulators and tribal leaders about the market. More research is needed to understand adherence to the Tobacco Directories by manufacturers and retailers, and their usefulness as a research tool to the tobacco control community.
