目的观察无呼吸道症状吸烟者肺功能的改变情况及其对戒烟的影响效果。方法选择128例无呼吸道症状吸烟患者,对其进行肺功能检测,而后予以戒烟干预措施,干预后再次观察肺功能改变情况以及评价其生活质量,随访观察其戒烟及复吸情况。结果与干预前比较,干预后各烟龄患者的PEF、MEF75、MEF50、MEF25、躯体功能、社会功能以及整体健康状况均升高明显,差异有统计学意义(P<0.05)。与随访3个月比较,随访6个月时患者戒烟的有效率升高明显,复吸率降低明显,差异均有统计学意义(P<0.05)。结论无呼吸道症状的吸烟者存在肺功能异常现象,戒烟干预可缓解其肺功能下降趋势,提高生活质量。
Objective To observe the change of pulmonary function in smokers without respiratory symptoms and its effect on smoking cessation. Methods A total of 128 patients with respiratory symptoms were selected for lung function test and then quit smoking interventions. The changes of lung function and quality of life were observed again after intervention. The smoking cessation and relapse were observed. Results Compared with pre-intervention, the PEF, MEF75, MEF50, MEF25, body function, social function and overall health status of patients of different smoking ages were significantly increased after intervention (P <0.05). Compared with 3 months after follow-up, the effective rate of smoking cessation significantly increased at 6 months follow-up, and the relapse rate was significantly lower (P <0.05). Conclusions There is an abnormal lung function in smokers without respiratory symptoms. Smoking cessation can relieve the decline of lung function and improve the quality of life.
