Abstract
Background: Cigarette smoking is the most important preventable cause of several diseases such as malignancies, pulmonary and cardiovascular diseases. Smoking cessation is now supported by both behavioral counseling and medical pharmacotherapy and is the only effective approach for slowing down an accelerated decline in forced expiratory volume in one second (FEV1). Our study aims to examine changes in forced expiratory volume in one second (FEV1) after smoking cessation for smokers attending our smoking cessation clinic their correlation to smokers’ demographic characteristics.
Methods: 114 smokers (48 males and 66 females), with a mean age of 48.36±10.49 years, were enrolled. They were classified in 4 groups, according to their age; <40 years (Group Α), 41-50 years (Group Β), 51-60 years (Group C), >60 years (Group D) and underwent Spirometry on the 1st day of visit, one month (2nd visit) and, 3 months later (3rd visit).
Findings: Statistically significant increase in FEV1 values at the 2nd and 3rd visit compared to the 1st visit was observed in smokers who quit smoking in Group Α, B and C (p<0.05). In addition, a statistically significant decrease in FEV1 values at the 2nd and 3rd visit compared to the 1st visit was noticed in smokers who continued smoking in Group B, C and D (p<0.05).
Conclusion: Smoking cessation achieved through smoking cessation support led to the improvement of FEV1 values within 3 months. The greatest benefit was observed in smokers under the age of 60.
