Abstract

Objective: Weight gain (WG) is one of the most widespread consequences of smoking cessation, although there is a great variability of post-cessation weight changes among smokers. Its approach is critical because it depicts an important barrier to trying to quit smoking and because it has been considered as a long-term predictor of relapse. Notwithstanding, little is known about post-cessation WG specifically among depressed smokers. The current study sought to: (1) describe the WG at posttreatment and follow-ups in smokers with depression, (2) examine the predictors of posttreatment WG, and (3) analyze whether post-cessation WG predicts smoking relapse at 6-month follow-up. Methods: The sample was comprised of 125 smokers with depression who achieved tobacco abstinence at posttreatment following a psychological smoking cessation intervention. Smoking abstinence was biochemically verified through carbon monoxide and urine cotinine. Multiple linear and hierarchical logistic regressions were conducted to examine predictors of WG at posttreatment and tobacco relapse at 6-month follow-up, respectively. Results: Abstinent participants gained an average of 3.55 kg at 6-month follow-up compared to 1.49 kg among participants who relapsed. Greater nicotine dependence (β = .372, p = .001) and diastolic pressure at baseline (β = .252, p = .021) predicted higher WG at end of treatment. WG at posttreatment increased the likelihood of relapse 6 months later (B = .303, OR = 1.354; 95% CI [1.006, 1.822]). Limitations: Weight concerns, disordered eating, and BMI were not recorded, and they could be related to the present findings. Conclusions: These results suggest that individuals with depression during treatment for smoking cessation should be regularly screened and offered treatment to prevent WG.

摘要

目的：体重增加（WG）是戒烟最普遍的后果之一，尽管吸烟者戒烟后体重变化存在很大差异。它的方法至关重要，因为它描绘了尝试戒烟的一个重要障碍，并且因为它被认为是复发的长期预测因素。尽管如此，人们对戒烟后 WG 尤其是抑郁吸烟者的情况知之甚少。目前的研究旨在：(1) 描述抑郁症吸烟者治疗后的工作量和随访情况，(2) 检查治疗后工作量的预测因素，以及 (3) 分析戒烟后工作量是否可以预测 6 个月时复吸的情况跟进。方法：样本由 125 名患有抑郁症的吸烟者组成，他们在接受心理戒烟干预后在治疗后实现了戒烟。通过一氧化碳和尿液可替宁对戒烟进行生化验证。进行多重线性和层次逻辑回归，分别检查治疗后 WG 和 6 个月随访时烟草复发的预测因子。结果：在 6 个月的随访中，戒烟的参与者平均体重增加了 3.55 公斤，而复发的参与者平均体重增加了 1.49 公斤。较大的尼古丁依赖性 ( β = .372, p = .001) 和基线舒张压 ( β = .252, p = .021) 预测治疗结束时的体重增加。治疗后的 WG 增加了 6 个月后复发的可能性 ( B = .303，OR  = 1.354；95% CI [1.006，1.822])。局限性：体重问题、饮食失调和体重指数没有记录，它们可能与目前的发现有关。结论：这些结果表明，在戒烟治疗期间患有抑郁症的个体应定期筛查并提供治疗以预防 WG。
