Results: Of 17 total analyses of quit attempts, nine (including the ITC US Survey) observed that African American smokers were more likely than whites to attempt to quit during a given year; seven found no differences. Whites were more likely than African Americans to be abstinent in five of six retrospective cohort analyses and in two of five considered community-and population-based cohort studies. Four of these 11 analyses, including one from the ITC US Survey, found no differences. Conclusions: Of 11 population-or community-based analyses, all seven that found significant differences indicated that whites were more likely to quit than African Americans. These findings, combined with the similar results from population-based birth cohort analyses, support the conclusion that white smokers are more likely to quit than African American smokers. Efforts to encourage and support quitting among all tobacco users remain a priority. Implications: This article provides a review of the literature on smoking cessation among African American and white smokers, and adds new analyses that compare quit attempts and abstinence between US African Americans and whites. Results demonstrate a clear distinction between the findings of cross-sectional and retrospective cohort studies with those of cohort studies. Reasons for these differences merit further study.

Our pilot results demonstrate that in a regional sample of primary care providers, providers rarely ask patients about their military history; however, they feel it is important information for patient care. While further study is needed, it may be necessary to provide education, specifically pertaining to military culture and health-related sequelae, to address barriers that may be limiting PCPs' provision of care for this population.
