Background: Obesity is an important health problem in the world, but also growing fast in the developing countries like India. Specifically, central obesity is associated with greater health risk than lower body obesity. Obesity is measured using waist circumference (WC) and body mass index (BMI). The association between body mass index, waist circumference and dynamic pulmonary function test (PFT) varies in different populations and shows controversial results.Methods and Materials: Present study covered 150 healthy sedentary employees of age group (30-40) years, who worked in an air conditioned environment of a private motor vehicle centers at Jabalpur for a minimum of six years. Their anthropometric measurements- height, weight, waist-hip circumference, chest expansion are measured to calculate body mass index, waist-hip ratio and total body fat%. Spirometry was performed after informed consent in all these subjects. FEV1, FVC, FEV1/FVC ratio, PEFR, FEF 25-75 was recorded. Results: When PFT variables of low BMI and overweight BMI group was compared with that of normal BMI group, the result shows inverse relation between BMI, WC and FEV1/FVC which indicates an obstructive airway diseases and it would be worsen in genetically prone high BMI subjects. FEF25-75 varies proportionately with increasing BMI indicates deteriorating lung functions. Conclusions: An attempt was done to bring awareness about variation of lung functions with increase in BMI and WC. Life style modifications and interventions to keep BMI and WC at normal level might help us in moving forward for eradication of obesity and impairment of pulmonary functions.
