Tobacco control environment in the United States and individual consumer characteristics in relation to continued smoking: Differential responses among menthol smokers?

Abstract Objective We used a consumer panel augmented with state-specific measures of tobacco control activities to examine the main effects and interactions among consumer behaviors, particularly menthol cigarette smoking, and tobacco control environment on cessation over a six-year period. Methods We used the Nielson Homescan Panel, which tracks consumer purchasing behaviors, and tobacco control information matched to panelist zip code. We focused on 1582 households purchasing ≥ 20 packs from 2004 to 2009. Our analysis included demographics; purchasing behavior including menthol versus nonmenthol use (≥ 80% of cigarettes purchased being menthol), quality preferences (average price/pack), purchase recency, and nicotine intake (nicotine levels of cigarettes purchased); and tobacco control metrics (taxation, anti-tobacco advertising, smoke-free policies). Results Menthol smoking (Hazard Ratio [HR] = 0.79, 95% Confidence Interval [CI] 0.64, 0.99), being African American (HR = 0.67, CI 0.46, 0.98), being male (HR = 0.46, CI 0.28, 0.74), higher quality premium preferences (HR = 0.80, CI 0.77, 0.91), lower recency (HR = 1.04, CI 1.02, 1.05), and higher nicotine intake rates (HR = 0.99, CI 0.99, 0.99) were related to continued smoking. No significant interactions were found. Conclusion While there were no interactions between menthol use and effects of tobacco control activities, we did find additional support for the decreased cessation rates among menthol cigarette smokers, particularly in the African American population.
