Disparities in smoking cessation between African Americans and Whites: 1990-2000.

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 30660 African Americans and 209828 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.
