Bupropion and Weight Control for Smoking Cessation
The purpose of this study is to determine whether the addition of bupropion (Zyban) to
cognitive behavioral therapy (CBT) will enhance longer-term tobacco abstinence in women.
cognitive behavioral therapy (CBT) will enhance longer-term tobacco abstinence in women.
Although rates of smoking have declined, the decrease in prevalence has been much less
pronounced in women than in men, and women are particularly vulnerable to ongoing
smoking-related morbidity and mortality. One important reason for gender differences in
smoking cessation is concern about cessation-related weight gain among women, which is
associated with poorer cessation outcome. We previously documented that cognitive behavior
therapy to minimize weight concerns (CBT) was effective in promoting cessation and
controlling weight gain among weight concerned women smokers. The current study is a
randomized, double-blind, controlled trial to determine whether the addition of bupropion
(Zyban) to CBT (12 sessions over 14 weeks, with 6 booster sessions) will enhance longer-term
abstinence. Bupropion was the clear medication of choice for this trial because it is
efficacious in promoting smoking cessation, attenuates cessation-related weight gain
(particularly in women), and relieves negative mood, which appears more common in
weight-concerned women. Four hundred fifty weight concerned women smokers will be randomized
to either CBT for weight concerns plus standard cessation or standard smoking cessation only
and six months of either bupropion (Zyban) or placebo (2 x 2 design). Primary outcome will
be rates of smoking abstinence at 1 year and time to relapse across the four treatment
conditions. In addition, we will determine the effects of these treatments on tobacco
withdrawal, mood, and weight. Results of this investigation will provide information on the
relative efficacy of the CBT intervention and bupropion alone and in combination and the
utility of drug and counseling strategies that are specifically tailored for a high-risk
population.
