Smoking cessation and oxidative stress, and effects of lifestyle.

戒烟对氧化应激的改善已有报道，主要是在健康受试者的干预研究中。目前的研究评估了戒烟诊所受试者的氧化应激水平。氧化应激的变化是根据研究对象的年龄、性别、身体活动水平、酒精摄入量、咖啡摄入量和身体质量指数等特征来评估的。受试者的每个特征都有相当大的差异。几个特征与氧化应激水平的变化有关，结果与先前的研究一致。几个性状对戒烟过程中氧化应激的变化起到了调节作用。

The improvement of oxidative stress by smoking cessation has been previously reported, mainly in intervention studies among healthy subjects. The current study evaluate the level of oxidative stress among subjects in smoking cessation clinics. The change in oxidative stress was evaluated according to the traits of subjects including age, sex, level of physical activity, alcohol intake, coffee consumption and BMI.Each trait of subjects varied in considerable degree. Several traits was associated with the change in the level of oxidative stress, and the results were in accordance with the previous studies. Several traits acted as effect modifiers for the change of oxidative stress in the process of smoking cessation.
