Peak expiratory flow rates in age matched smokers and non-smokers in a tertiary care hospital

Introduction: Tobacco smoking is a major risk factor for various respiratory diseases in humans. PEFR is a useful parameter to monitor airway obstruction, its severity, variation and evaluation of treatment. Aim of the study: The aim of this study was to assess the PEFR in age-matched asymptomatic smokers and non-smokers. Materials and methods: Study was conducted in 50 asymptomatic smokers and 50 healthy nonsmokers. PEFR recording was done using Wright's peak flow meter. Results: On comparing the anthropometric indices, mean weight of the smokers was 61.23 whereas it was 66.88 in nonsmokers which was statistically significant. Mean PEFR of smokers was 354.16 and that of nonsmokers was 409.60 which were significant. Smokers smoking for less than 10 years had a mean PEFR of 368 as against the PEFR of 308 in those with smoking history for more than 10 years. Beedi smokers had the lowest mean PEFR of 256.5 when compared to cigarette smokers mean PEFR of 352.60. Conclusions: Smoking had a significant impact on the lung function of smokers even though they are asymptomatic. Smokers had a significant reduction in their weight too. Smoking for a longer duration of years affects both cigarette and beedi smokers but the worst was with the Beedi smokers. PEFR is an easy and effective method of detecting deterioration in lung function in OPD setting thus helping to create awareness among smokers to quit smoking as early as possible.
