Predictors of cessation pharmacotherapy use among black and non-Hispanic white smokers.

INTRODUCTION: Use of pharmacotherapy for smoking cessation improves quit rates, but these treatments are underutilized, particularly among Black smokers. Attitudes toward pharmacotherapy may differ between racial/ethnic minorities and Caucasian smokers. It was hypothesized that Black and non-Hispanic White smokers would differ in their attitudes toward pharmacotherapy and that the association between attitudes toward and actual use of pharmacotherapy would differ by race.
METHODS: The study consisted of a single, cross-sectional telephone-based survey of current smokers (N = 697), which examined the relationship between race, attitudes toward pharmacotherapy, and pharmacotherapy usage in a representative bi-racial sample (39% Black).
RESULTS: Black smokers were significantly less likely to report ever use of pharmacotherapy (23%) than Caucasians (39%; odds ratio [OR] = 0.46; 95% CI: 0.33-0.66). Compared with Caucasians, Blacks had significantly less favorable attitudes toward pharmacotherapy, including disbelief about efficacy (p = .03), addiction concerns (p = .03), harmfulness of pharmacotherapy (p = .008), and need for treatment of any kind to quit smoking (p = .004). In a multiple logistic regression, racial group (Caucasian is referent: OR = 0.55, p = .003), addiction concerns (OR = 0.80, p < .01), and need for treatment of any kind to quit smoking (OR = 1.52, p < .001) were predictive of pharmacotherapy use.
CONCLUSIONS: These findings replicate and build upon previous research demonstrating underutilization of pharmacotherapy and enduring misconceptions about pharmacotherapy, particularly among Black smokers. Regardless of racial group, misconceptions about pharmacotherapy are related to lower rates of use. Efforts to improve understanding about the efficacy and safety of these products are needed to boost utilization and impact cessation rates.
