Tobacco smoking remains the leading preventable cause of death among American women. Aerobic exercise has shown promise as an aid to smoking cessation because it improves affect and reduces nicotine withdrawal symptoms. Studies outside the realm of smoking cessation have shown that yoga practice also reduces perceived stress and negative affect.
This pilot study examines the feasibility and initial efficacy of yoga as a complementary therapy for smoking cessation. Fifty-five women were given 8-week group-based cognitive behavioral therapy for smoking cessation and were randomized to a twice-weekly program of Vinyasa yoga or a general health and wellness program (contact control). The primary outcome measure was 7-day point prevalence abstinence at the end of treatment validated by saliva cotinine testing. Longitudinal analyses were also conducted to examine the effect of intervention on smoking cessation at 3- and 6-month follow-up. We examined the effects of the intervention on potential mediating variables (e.g., confidence in quitting smoking, self-efficacy), as well as measures of depressive symptoms, anxiety, and perceived health (SF-36).
At end of treatment, women in the yoga group had a greater 7-day point-prevalence abstinence rate than controls (odds ratio [OR], 4.56; 95% CI, 1.1-18.6). Abstinence remained higher among yoga participants through the six month assessment (OR, 1.54; 95% CI, 0.34-6.92), although differences were no longer statistically significant. Women participating in the yoga program also showed reduced anxiety and improvements in perceived health and well-being when compared with controls.
Yoga may be an efficacious complementary therapy for smoking cessation among women.
吸烟仍然是美国女性的主要可预防死因。有氧运动已被证明是戒烟的辅助手段，因为它可以改善情绪并减轻尼古丁戒断症状。在戒烟领域之外的研究表明，瑜伽练习也可以减轻感知压力和负面情绪。
这项初步研究考察了瑜伽作为戒烟辅助疗法的可行性和初步疗效。55 名女性接受了为期 8 周的团体认知行为疗法戒烟，并随机分为每周两次的 Vinyasa 瑜伽计划或一般健康和保健计划（接触对照组）。主要结局测量是治疗结束时通过唾液可替宁检测验证的 7 天点患病率戒烟率。还进行了纵向分析，以研究干预对 3 个月和 6 个月随访时戒烟的影响。我们检查了干预对潜在中介变量（例如戒烟信心、自我效能感）的影响，以及抑郁症状、焦虑和感知健康（SF-36）的测量。
在治疗结束时，瑜伽组的女性 7 天点患病率戒烟率高于对照组（比值比[OR]，4.56；95%置信区间，1.1-18.6）。在 6 个月评估时，瑜伽参与者的戒烟率仍然较高（OR，1.54；95%置信区间，0.34-6.92），尽管差异不再具有统计学意义。与对照组相比，参加瑜伽计划的女性焦虑程度也有所降低，感知健康和幸福感也有所改善。
瑜伽可能是女性戒烟的有效辅助疗法。
