5�C24.99), overweight (BMI = 25.0�C29.99), or obese (BMI > 30.0). Chi-square tests and ANOVA were used to compare across these weight categories on the initial demographic variables as well as tobacco history, weight concerns, motivation, selleck kinase inhibitor and depressive symptoms. To evaluate gender differences, a general linear model was fit, with terms for gender, BMI group, and the gender by BMI group interaction. In addition, two-sample tests of weight concerns by gender were conducted separately for normal weight, overweight, and obese participants based on the general model. RESULTS Descriptive information as well as information on the smoking history and current smoking behavior of participants is shown in Table 1. As planned, we obtained a sample comprised of 34.6% (n = 206) normal weight, 30.

6% (n = 182) overweight, and 34.8% (n = 207) obese quitline callers. There were no differences in age, race, ethnicity, educational background, depressive symptoms, tobacco use frequency, duration of smoking, number of previous quit attempts or maximum weight gain in previous quit attempts across weight categories. In addition, overweight and obese smokers did not differ from normal weight smokers on motivation to quit smoking. Table 1. Demographic Information and Weight Concerns by Weight Category Smoking-Related Weight Concerns Smoking-related weight concerns differed across the weight categories. As shown in Figure 1, quitline callers who were obese reported significantly greater concern about postcessation weight gain than did either normal weight or overweight callers, F(2, 592) = 20.

35, p < .0001. Similarly, obese smokers reported feeling significantly less confident in their ability to maintain their weight without smoking than did normal weight or overweight callers, F(2, 592) = 7.67, p = .0005. Figure 1. Weight concerns by weight status. There also were differences by weight categories in the amount of weight smokers were willing to tolerate after quitting. Smokers of normal weight were willing to tolerate significantly larger weight gains than were either overweight or obese smokers, F(2,574) = 30.59, p < .0001. Indeed, normal weight smokers were willing to tolerate a 7.0kg weight gain (7.0��5.6kg) compared to 4.6 (��4.7) and 3.4 (��3.5) kg among overweight and obese smokers. Gender Differences in Smoking-Related Weight Concerns There were significant gender differences in weight and weight gain concerns.

A significantly greater proportion of female relative to male callers were obese (38.2% vs. 28.4%, p = .011). Female callers also consistently endorsed greater concern about postcessation weight gain than did males, F(1,588) = 24.04, p < .0001. In addition, as shown in Table Dacomitinib 2, the gender effect is more prominent among normal and overweight smokers. There were no differences in motivation to quit smoking, however, between men and women. Table 2.
