Ethnic differences in alcohol treatment outcomes and the effect of concurrent smoking cessation treatment.
The Timing of Alcohol and Smoking Cessation (TASC) Study tested the optimal timing of smoking cessation treatment in an alcohol-dependent population. Previously reported results suggest that providing concurrent smoking cessation treatment adversely affects alcohol outcomes. The purpose of this analysis was to investigate whether there are ethnic differences in alcohol and tobacco outcomes among a diverse sample of alcohol-dependent smokers using data from the TASC trial in which 499 participants were randomized to either concurrent (during alcohol treatment) or delayed (6 months later) smoking intervention. This analysis focused on smokers of Caucasian (n=381) and African American (n=78) ethnicity. Alcohol outcomes included 6 months sustained alcohol abstinence rates and time to first use of alcohol post-treatment. Tobacco outcomes included 7-day point prevalence smoking abstinence. Random effects logistic regression analysis was used to investigate intervention group and ethnic differences in the longitudinally assessed alcohol outcomes. Alcohol abstinence outcomes were consistently worse in the concurrent group than the delayed group among Caucasians, but this was not the case for African Americans. No significant ethnic differences were observed in smoking cessation outcomes. Findings from this analysis suggest that concurrent smoking cessation treatment adversely affects alcohol outcomes for Caucasians but not necessarily for African Americans.
