Abstract
Objectives. We examined socioeconomic disparities in a community-based tobacco dependence treatment program. Methods. We provided cognitive-behavioral treatment and nicotine patches to 2739 smokers. We examined treatment use, clinical and environmental, and treatment outcome differences by socioeconomic status (SES). We used logistic regressions to model end-of-treatment and 3- and 6-month treatment outcomes. Results. The probability of abstinence 3 months after treatment was 55% greater for the highest-SES than for the lowest-SES (adjusted odds ratio [AOR] = 1.55; 95% confidence interval [CI] = 1.03, 2.33) smokers and increased to 2.5 times greater for the highest-SES than for the lowest-SES smokers 6 months after treatment (AOR = 2.47; 95% CI = 1.62, 3.77). Lower-SES participants received less treatment content and had fewer resources and environmental supports to manage a greater number of clinical and environmental challenges to abstinence. Conclusions. Targets for enhancing therapeutic approaches for lower socioeconomic groups should include efforts to ensure that lower-SES groups receive more treatment content, strategies to address specific clinical and environmental challenges associated with treatment outcomes for lower-SES smokers (i.e., higher dependence and stress levels and exposure to other smokers), and strategies to provide longer-term support.
