A more comprehensive understanding of the factors regarding weight control in individuals with overweight or obesity after quitting smoking is needed. The study aimed to analyze the changes of in-treatment variables during a smoking cessation intervention and examine their impact on weight.
A total of 120 individuals who smoke with overweight or obesity (M = 31.75 ± 4.31; 54.16 % female) participated in a cognitive-behavioral therapy for smoking cessation and weight control or the same treatment plus contingency management. Weight, smoking variables (cotinine and continuous abstinence), eating behaviors (appetite, grazing), exercise, and sleep were assessed weekly throughout the treatment.
More participants gained weight over time with reduced nicotine use or abstinence. There was a tendency during treatment to increase appetite and exercise time, while grazing episodes and sleeping hours remained stable. Higher baseline weight (p < .001), greater cotinine reduction (p = .021) and time (p = .009) were associated with greater weight gain, while more hours of exercise (p = .003), no appetite changes (p = .003) and diminished appetite (p < .001) were associated with less gain over the treatment. Both treatment conditions showed similar results in all in-treatment variables.
Individuals with overweight and obesity with higher baseline weight and higher baseline cotinine levels during smoking cessation interventions may require special attention to improve weight outcomes. Exercise and appetite regulation may be useful for mitigating weight gain in smoking cessation interventions for individuals with overweight or obesity.
需要更全面地了解超重或肥胖的吸烟者戒烟后控制体重的相关因素。本研究旨在分析戒烟干预过程中治疗变量的变化，并研究其对体重的影响。
共 120 名超重或肥胖的吸烟者（M=31.75±4.31；54.16%为女性）参加了认知行为疗法戒烟和体重控制治疗，或接受相同的治疗加附带管理。每周评估体重、吸烟变量（可替宁和持续戒断）、饮食行为（食欲、乱吃）、运动和睡眠。
随着尼古丁使用量的减少或戒断，更多的参与者体重增加。治疗期间食欲和运动时间有增加的趋势，而乱吃和睡眠时间保持稳定。较高的基线体重（p<.001）、较大的可替宁减少（p=.021）和时间（p=.009）与体重增加较多有关，而更多的运动时间（p=.003）、食欲无变化（p=.003）和食欲减退（p<.001）与治疗期间体重增加较少有关。两种治疗条件在所有治疗变量中均显示出相似的结果。
在戒烟干预中，基线体重较高和可替宁水平较高的超重和肥胖者可能需要特别注意以改善体重结局。运动和食欲调节可能有助于减轻超重或肥胖者戒烟干预中的体重增加。
