ABSTRACT

Cigarette smoking is the most important risk factor for COPD. Cessation of smoking is the most effective way for prevention or treatment of COPD. The study group consisted of 160 patients which was divided into 2 equal groups [intervention and control]. Sampling method was simple. In intervention group counseling for cessation of smoking was performed. The data were collected by use of the questionnaires, Fagrostrom test, registered FEV[1] rate and smoking rate. Measurement of FEV[1] before and 3 months after the study, was performed by using a hand spirometer device. Data were analyzed by means of descriptive and inferential methods, such as x[2] exact fisher test, t-test and ect... usting SPSS Statistic program. After 3 months of study, reduction in smoking rate in intervention group was%66, while this figure for control group was 41.3% [p=0.001]. 41.3% and 26.3% of the subjects of the intervention and control groups respectively, quitted smoking. 3 months after study the rate of FEV[1] in intervention group was significantly [%13.2] higher than those of control group [0.5%] which revealed a significant statistical difference [p<0.05%].The result of this study supported the use of such measures encouraging cessation of smoking which can lead to an increase in FEV[1] and a decrease in FEV[1] reduction with improvement of pulmonary function in COPD patients
