Abstract
Objective: To determine the effect of comorbidity as well as other demographic, pulmonary function test and smoking- related parameters on smoking cessetion.
Methods: Between May-2013 – December-2013, smokers followed at least for one month were included. The demographic data, comorbid diseases, PFTs, smoking history and medication were recorded. The effect of comorbid disease as well as demographics, PFTs, smoking-related parameters on smoking cessetion were analyzed. Chi-square and Mann Whitney –U tests were used in statistical analysis.
Results: For 206 smokers, median follow up was 3 months and 121(58.7%) were male, 85(41.3%) were female. Mean age was 41.3±12.2 (16-79). Smoking history was 27.6 pack-years while mean Fagerstrom Dependence Score was 6.3. Comorbid disease was existing in 124(60.2%) cases. Physchiatric diseases 43(20.9%) were the leading comorbid disease followed by heart failure and hypertension (6.7% and 8.3% respectively). Of the cases, 74.8% has been discontinued even in the first month of follow-up and 1 month quitting rate (out of 206 patients) was 21.4% while it was 10.2% for 3 months (out of 128 patients). Comorbid diseases showed no statistically significant effect on quitting rates. Considering for 3-months-period, quitters were older (mean age:51.8 vs. 40.4; p=0.003), more heavy smokers ( 40.5 vs. 27.1 pack-years; p=0.006) and with lower FEV1/FVC ratio (71.9 vs. 77.9; p=0.049)
Conclusion: Many of the smokers who attempted to quit has failed in following smoking cessetion program. Comorbidity was not found to be effecting quitting rates. Older and more heavy smokers as well as smokers with relatively lower FEV1/FVC ratio were found to be more succesive in quitting smoking.
