Abstract

Background: Recent cross-sectional evidence suggests that the effect of depression on smoking prevalence and quit ratios differs by race/ethnicity.

Purpose: This study prospectively examined the main and interactive effects of race/ethnicity and depressive symptoms on smoking cessation during a specific quit attempt among smokers receiving cessation treatment.

Methods: Data from a longitudinal study of smokers in treatment were examined using continuation ratio logit modeling. Continuous abstinence across Weeks 1, 2, and 4 post-quit was the outcome variable. Data were collected between March 2005 and November 2007, and the current study analyses were conducted in April 2010.

Results: Depressive symptoms predicted significantly lower cessation rates for whites and African Americans. In contrast, among Latinos there was no relationship between depression and cessation.

Conclusions: This research is the first to prospectively demonstrate a racially/ethnically differentiated effect of depressive symptoms on smoking cessation, and it has implications for targeted smoking-cessation treatments as it indicates that depression may not be a key treatment target for Latinos.
