Background
Use and effectiveness of tobacco quitlines by weight is unknown.
Purpose
Determine if baseline weight is associated with treatment engagement, cessation or weight gain following quitline treatment.
Methods
Quitline participants (n=595) were surveyed at baseline, three and six months.
Results
Baseline weight was not associated with treatment engagement. In unadjusted analyses, overweight smokers reported higher quit rates and were more likely to gain weight after quitting than obese or normal weight smokers. At three months, 40% of overweight vs. 25% of normal weight or obese smokers quit smoking (p=0.01); 42% of overweight, 32% of normal weight, 33% of obese quitters gained weight (p=0.05). After adjusting for covariates, weight was not significantly related to cessation (approaching significance at six months, p=.06) or weight gain.
Conclusions
In the first quitline study of this kind, we found no consistent patterns of association between baseline weight and treatment engagement, cessation or weight gain.
