Abstract
Aim: There are several factors effecting smoking cessation rates. We aimed to evaluate effect of pulmonary function tests (PFT) on short-term smoking cessation rates.
Material-method: Cases who applied to smoking cessation clinic between January 2012-September 2014,underwent PFT and followed up for at least 3 months were recruited in this retrospective cohort study.The degree of Fagerstrom score, duration of smoking(pack-years), comorbidities were questioned,PFT and end-expiratory carbonmonoxide(CO) were noted at first visit.Following behavioural therapy and prescription of the drugs,cases were followed monthly for 3 months,the second visit being within next 15 days.Cases with CO of 0-5 ppm were considered as quitters.Factors effecting 3-month smoking cessation rates were statistically analysed.
Results: Mean age of 639 cases -389 male(60.9%),250 female(39.1%)- was 41.8±12.2.Mean Fagerstrom score was 6.1±2.3,mean duration of smoking was 27.0±16.5 pack-years.One hundred eighty two(28.5%) cases used prescribed medication and came for follow-up visits. Considering 74 quitters,success rate was 11.5% for the whole study population and was 40.6% for 182 cases who were treated and followed.Among quitters male ratio(p=0.042),age(p=0.000),pack-years(p=0.000),COPD ratio(p=0.019),obstructive PFT rates(p=0.000) were significantly higher and FEV1/FVC was significantly lower(p=0.000).Logistic regression analyses revealed that effect of age and male gender was significant(p=0.000;p=0.049) and effect of obstructive PFT was of remarkable significance(p=0.066).
Conclusion: Short term cessation success is effected by age,male gender,as well as obstructive PFT.These cases deserve special support in smoking cessation clinics.
