Heart, body, and soul: impact of church-based smoking cessation interventions on readiness to quit.
BACKGROUND
Given the relatively low spontaneous quit rates and poor treatment outcomes among African American smokers, this study was designed to evaluate the effects of a multimodal culturally relevant intervention for smoking behavior change compared with a self-help strategy among urban African Americans in Baltimore churches.


METHODS
This randomized controlled trial in urban African American churches used the stages of change model to compare the effectiveness of two interventions in moving smokers along a continuum toward smoking cessation. Twenty-two churches were randomly assigned to either an intensive culturally specific intervention or a minimal self-help intervention. Smokers were interviewed at baseline church health fairs and at a 1-year follow-up. Self-reported quitters at follow-up were evaluated using saliva cotinine and exhaled carbon monoxide levels (CO). Stages of change were measured by applying a standardized stages of change instrument to individual interview response sequences. Analysis compared the two intervention groups at 1-year follow-up with baseline stages. Outcomes included quit rates and positive progress along the stages of change.


RESULTS
Multiple logistic regression results, controlling for intrachurch correlation and demographic and baseline smoking characteristics, showed that the multimodal cultural intervention group was more likely to make positive progress along the stages of change continuum, compared with self-help intervention group (OR = 1.68; P = 0.04). Church denomination and intervention status interacted in the multivariate model; Baptists in the intensive intervention were three times (OR = 3.23; P = 0.010) more likely to make progress than all the other denomination groups.


CONCLUSIONS
The multimodal culturally relevant intervention was more likely than a self-help intervention to positively influence smoking behavior. This is the first community-based intervention study to report progress along the stages of change as a process-oriented measure of success. It is notable that a spiritually based model focusing on environmental sanctions was more likely than a standard church disseminated self-help intervention to positively influence smoking behavior in an urban African American population.
