Depressive symptoms are consistently shown to be related to poor smoking cessation outcomes. Aerobic exercise is a potential treatment augmentation that, given its antidepressant and mood enhancing effect, may bolster cessation outcomes for smokers with elevated depressive symptoms. Lower enjoyment of physical activity may inhibit the acute mood enhancing effects of aerobic exercise. The current study investigated the associations between depressive symptoms, physical activity enjoyment and the acute mood experience from exercise among low-active smokers with elevated depressive symptoms.
Daily smokers with elevated depressive symptoms (N=159; = 45.1, = 10.79; 69.8% female) were recruited for a randomized controlled exercise-based smoking cessation trial. Participants self-reported levels of depressive symptoms, physical activity enjoyment, and rated their mood experience (assessed as "mood" and "anxiety") before and after a standardized aerobic exercise test.
Hierarchical regression analysis revealed that depressive symptom severity accounted for significant unique variance in physical activity enjoyment ( =.041, = -2.61, = .010), beyond the non-significant effects of gender and level of tobacco dependence. Additionally, physical activity enjoyment was a significant mediator of the association between depressive symptom severity and acute mood experience ("mood" and "anxiety") following the exercise test.
Physical activity enjoyment may explain, at least in part, how depressive symptom severity is linked to the acute mood experience following a bout of activity. Interventions that target increasing physical activity enjoyment may ultimately assist in enhancing the mood experience from exercise, and therefore improve smoking cessation likelihood, especially for smokers with elevated depressive symptoms.
抑郁症状一直被证明与戒烟效果不佳有关。有氧运动是一种潜在的辅助治疗方法，鉴于其抗抑郁和改善情绪的作用，可能会提高抑郁症状较高的吸烟者的戒烟成功率。对体育活动的较低享受度可能会抑制有氧运动对情绪的急性改善作用。本研究调查了抑郁症状、体育活动享受度与抑郁症状较高的低活动水平吸烟者运动后急性情绪体验之间的关联。
招募了抑郁症状较高的每日吸烟者（N = 159；平均年龄 = 45.1岁，标准差 = 10.79；69.8%为女性）参与一项基于运动的随机对照戒烟试验。参与者自我报告抑郁症状水平、体育活动享受度，并在标准化有氧运动测试前后对他们的情绪体验（评估为“情绪”和“焦虑”）进行评分。
分层回归分析显示，抑郁症状严重程度在体育活动享受度方面解释了显著的独特方差（β = 0.041，t = -2.61，p = 0.010），超出了性别和烟草依赖水平的非显著影响。此外，体育活动享受度是运动测试后抑郁症状严重程度与急性情绪体验（“情绪”和“焦虑”）之间关联的显著中介变量。
体育活动享受度可能至少部分解释了抑郁症状严重程度与一次活动后急性情绪体验之间的联系。旨在提高体育活动享受度的干预措施最终可能有助于增强运动带来的情绪体验，从而提高戒烟可能性，尤其是对于抑郁症状较高的吸烟者。
