Weight Concerns and Use of Cigarettes and E-Cigarettes among Young Adults.

Higher weight concerns have been associated with higher cigarette smoking, particularly among women, partly because smoking is perceived to limit appetite for food. E-cigarettes are increasingly used as an alternative to combustible cigarettes and are widely believed to be less harmful than cigarettes. Currently it is not known whether weight concerns are associated with e-cigarette use among young adults. In this study, we tested the association between weight concerns and cigarette and e-cigarette use and use susceptibility among young adults. Cross-sectional data were collected from college students (N = 470; M age = 20.9; SD = 2.1; 65% women). Results indicated that weight concerns were significantly associated with lifetime and current cigarette smoking status, current cigarette smoking frequency and cigarette use susceptibility (among never smokers), adjusting for demographics variables. Weight concerns were not associated with lifetime or current e-cigarette use status or e-cigarette use susceptibility, adjusting for demographics and cigarette use status. However, higher weight concerns were associated with higher frequency of current e-cigarette use, adjusting for demographic variables and current cigarette smoking frequency. These findings imply that even though weight concerns may not motivate e-cigarette use as strongly as cigarette use, weight concerns may influence higher intensity of e-cigarette use among users.
