Disparities in Smoking Cessation Between African Americans and Whites: 1990-2000

Abstract

Objectives. We examined disparities in smoking cessation rates between African Americans and Whites from 1990 through 2000. Methods. We performed an analysis of smoking cessation with data from the National Health Interview Surveys of 30,660 African American and 209,828 Whites, 18 to 64 years old, with adjustment for covariates in multiple logistic regression models. Results. Whites were significantly more likely than African Americans to be former smokers, and this disparity in the quit ratio persisted from 1990 through 2000. After adjustment for covariates, disparities were substantially reduced especially among women. Among former smoker, African Americans were significantly more likely than Whites to have quit successfully within the past 10 years. Conclusion. Statistical adjustment for covariates reduces African American-White disparities in quit ratios, and recent cessation patterns suggest possible future reductions in disparities.
