Background: Young adulthood provides an enormous opportunity to alter trajectories of smoking behaviour for a large public health impact., Objective: The purpose of this study was to examine correlates of perceived barriers to quitting smoking and reasons to quit in a sample of young adult current and former smokers., Methods: This study used data from the 2011 National Young Adult Health Survey, a random-digit-dial cellphone survey. Participants were US young adult current smokers aged 18-34 (n = 699) and young adults who were either current smokers who had made a quit attempt in the past-year (n = 402) or former smokers (n = 289). Correlates of barriers to quitting smoking and reasons for quitting smoking were assessed using bivariate and multivariable analyses., Results: More than half of current smokers identified 'loss of a way to handle stress' (59%) and 'cravings or withdrawal' (52%) as barriers to quitting. Female gender, daily smoking and intention to quit remained significantly associated with endorsing 'loss of a way to handle stress' as a barrier to quitting in multivariable analyses. The two most popular reasons for quitting smoking were physical fitness (64%) and the cost of tobacco (64%)., Conclusion: These findings highlight barriers to cessation and the reasons that young smokers give for quitting. This information may be helpful to physicians as they counsel their young adult patients to quit smoking., (© The Author 2016. Published by Oxford University Press. All rights reserved.

Background: Tobacco use remains high among blue-collar workers, the health consequences of which may be compounded by occupational dust exposure. Detailed data on tobacco use among workers in dusty industries are lacking. Methods: The 2006 to 2012 National Survey on Drug Use and Health was used to compare current tobacco use prevalence [including cigarettes, smokeless tobacco (SLT), and both (dual use)] among male workers in three dusty industries to all other employed men using bivariate and multivariate analysis. Results: Smoking rates were high among extraction (39.9%) and construction (38.5%) workers. Increased odds of SLT (odds ratio = 3.3) and dual use (odds ratio = 2.6) were observed among dusty-industry workers compared with other employed men. The prevalence of any tobacco use was unexpectedly high among extraction workers (60.4%). Conclusions: Disparities in tobacco use behaviors by industry may point to opportunities for targeted workplace tobacco cessation programs. [ABSTRACT FROM AUTHOR]
