Implication

Cohort study reveals reduced smoking cessation rates in depressed individuals, indicating that depressive symptoms hinder long-term quitting success.

Key Points

To evaluate the relationship between depressive symptoms and the dynamics of cigarette smoking, particularly smoking prevalence and long-term cessation rates.
Analyzed cross-sectional data from the first National Health and Nutrition Examination Survey and longitudinal data from the Epidemiologic Follow-up Study with 9 years of follow-up.
Assessed depressive symptoms using the Center for Epidemiologic Studies Depression Scale, setting a score of 16 or greater as the cutoff for depression.
Evaluated cessation rates using a Cox proportional hazards model adjusted for baseline amount smoked, sex, age, and educational attainment.
Cross-sectional analysis demonstrated that current smoking prevalence increased and the quit ratio decreased with higher depressive symptom scores.
In the longitudinal cohort, the estimated 9-year quit incidence was 9.9% for depressed smokers versus 17.7% for nondepressed smokers.
Depressed smokers were 40% less likely to quit smoking than nondepressed smokers after multivariable adjustment (relative risk, 0.6).
