PURPOSE: In India smoking is a common habit prevalent in both urban and rural areas. Cigarette smoking has extensive effects on respiratory function and is clearly implicated in the etiology of a number of respiratory diseases, chronic bronchitis, emphysema, and bronchial carcinoma. Because of the long delay between the cause and full effect, people tend to misjudge the hazards of tobacco To study the effects of type, quantity and duration of smoking on the pulmonary function tests.(FEV1 ,FVC, FEV1/FVC%, PEFR, FEF25%, FEF50%, FEF75%, FEF25-75%)
METHODS: The pulmonary functions were done on a computerized spirometer in 300 subjects comprising of 150 smokers and 150 non smokers attending department of pulmonary medicine
RESULTS: Amongst 300 study subjects, 114 (38%) had normal lung functions whereas 186 (62%) had impaired lung functions, out of which 134 (72.04%) were smokers and only 52 (27.95%) were non-smokers.The association between smoking and impaired PFT was statistically highly significant. In this study bidi smoking was most common. Almost all the pulmonary function parameters were significantly reduced in smokers and obstructive pulmonary impairment was commonest.Respiratory symptom like cough, expectoration, breathlessness were more in smokers as compared to non-smokers. In smokers, restrictive and mixed pattern in majority seen among heavy smokers 60% and 80% respectively. Obstructive pattern in majority seen with moderate smokers 45.6% and normal pattern only with light smokers.
CONCLUSIONS: Tobacco smoking in any form, bidi, cigarette or both has significantly deleterious effects on pulmonary functions. The smoking epidemic is so huge that every effort is needed to launch effective campaign to protect our people and maintain a good quality health life.
CLINICAL IMPLICATIONS: Spirometry by a trained health professional gives an indication of lung health by measuring airway obstruction. As a screening tool in smokers it has the potential to detect early changes before any significant symptoms are evident.It has been seen smokers diagnosed with COPD stopped smoking significantly more often than those with normal lung function.
