Arizona Study Finds BMI Changes in Adolescents Treated with Bupropion SR for Smoking Cessation

Adolescents who are overweight and smoke present significant health challenges because of their lasting effects on overall health. Weight gain after smoking cessation is a barrier to quitting as well as a negative consequence to health. A study by researchers at the University of Arizona Mel and Enid Zuckerman College of Public Health found that adolescents treated with bupropion SR for smoking cessation reported changes in the body mass index (BMI) z-scores.

The adolescent smokers participated in a dose-ranging clinical trial of bupropion SR (150 mg/day and 300 mg/day) for smoking cessation. A total of N = 296 adolescent smokers (placebo n = 100, 150 mg/day n = 101, 300 mg/day n = 95) with a BMI z-score of 0.5 (sd: 1.4), 0.5 (sd: 1.3), and 0.5 (sd: 1.2) in the placebo, 150 mg/day, and 300 mg/day groups, respectively, were followed for 6 months.

Adolescents in the 300 mg/day group had a significant reduction in BMI z-score 6 weeks after quitting (β = −0.16, CI = (−0.29, −0.04), P-value = 0.01). This result was not sustained at the 6-month follow-up.

A reduction in BMI z-score during smoking cessation with bupropion has important implications for the future of adolescent smoking cessation. These results are particularly relevant for adolescents who have either overweight, obese or who have reservations about quitting for fear of gaining weight or BMI.
