A Study on Effects of Severity of Cigarette Smoking On Lung Functions of Adult Population in North Gujarat Region.

ABSTRACT

Backgrounds And Objectives: Tobacco consumption in different forms is a common addiction in the socio-economically handicapped population in many developing countries there are few data on the uantitative effects of cigarette smoking on lung function in young adults. These effects are important in the understanding of the early stages of chronic airflow obstruction. Material and method: Our study was performed on a total of 100 subjects (50 control and 50 were cigarette smokers) with the age group between 15-40 years were selected. Smokers were categorized into mild, moderate and severe smokers on the basis of number of cigarette smoke per day. Computerised spirometery examination was performed on both control and smokers. Results and Interpretation: We observed an inverse dose–response relation between smoking and FEV1, FVC, FEV1/FVC, PEFR; FEF etc. severe smokers had a low FEV1, PEFR, and FVC than control group. Conclusion: Cigarette smoking has a dose related adverse effect on the evolution of ventilatory lung function in young adulthood. Cigarette smoking is associated with evidence of airway obstruction and slowed growth of lung function in adults, exposure to cigarette smoke led to a greater increase in the number of mucus- producing tracheal goblet cells that enhanced the airway obstruction that may be the cause for decline in the lung functions.
