Associations of subjective social status with nondaily and daily smoking.

Objectives: To explore associations between subjective social status (SSS) and smoking level among 2274 adult current smokers.

Methods: Associations were investigated using a covariate-adjusted proportional odds cumulative logit model. Moderation (via race/ethnicity or sex) and mediation (via depressive symptoms, social/emotional support, or life satisfaction) were explored in additional models.

Perceptions of addiction, attempts to quit, and successful quitting in nondaily and daily smokers.

We aimed to qualitatively examine differences in perceptions of addiction, attempts to quit, and successful quitting among nondaily versus daily college student smokers. We conducted 16 focus groups with a total of 73 college student smokers from the southeastern U.S.

Factors associated with discontinuation of bupropion and counseling among African American light smokers in a randomized clinical trial.

Background: African Americans are at risk of inadequate adherence to smoking cessation treatment, yet little is known about what leads to treatment discontinuation.

Purpose: The purpose of this study was to examine the factors associated with discontinuation of treatment in African American light smokers (≤10 cigarettes per day).

Methods: Bupropion plasma levels and counseling attendance were measured among 540 African American light smokers in a placebo-controlled randomized trial of bupropion.

Perceived treatment assignment and smoking cessation in a clinical trial of bupropion versus placebo.

Introduction: Psychoactive effects of smoking cessation medi cations such as bupropion may allow participants in smoking cessation clinical trials to correctly guess their treatment assignment at rates greater than chance. Previous research has found an association between perceived treatment assignment and smoking cessation rates among moderate to heavy smokers (≥ 10 cigarettes per day [cpd]) in two bupropion clinical trials.

Methods: The aim of this study was to determine the impact of perceived treatment assignment on end-of-treatment cotinine-verified smoking abstinence at Week 7 and Week 26 among African American light smokers (≤ 10 cpd) enrolled in a double-blind, placebo-controlled study of bupropion.

Adherence to varenicline among African American smokers: an exploratory analysis comparing plasma concentration, pill count, and self-report.

Introduction: Measuring adherence to smoking cessation pharmacotherapy is important to evaluating its effectiveness. Blood levels are considered the most accurate measure of adherence but are invasive and costly. Pill counts and self-report are more practical, but little is known about their relationship to blood levels.
