Association of body mass index with pulmonary function parameters in females with non-obstructive airway disease identified by spirometric protocols attending Bankura Sammilani Medical College

Background: The effect of body mass index (BMI) on the incidence and prevalence of airway obstructive diseases-asthma, chronic bronchitis, and emphysema—is not clear. The nature of the relationship between BMI and airway obstructive diseases are also complicated by the potential effect respiratory symptoms can have on appetite and physical activity. Aims: Proposed study was to find out the association between body mass index and lung functions in females with Non-obstructive airway disease identified by spirometric protocols. Materials and Methods: A retrospective analysis of the spirometry data obtained between August 2018 and January 2019 was conducted in the Physiology Department, B. S. Medical College, Bankura for six months. In this study above 200 test results over female subjects were taken from study database. Out of those 138 test results of Non-obstructive airway disease were included considering inclusion and exclusion criteria. Results: The Study shows PEFR and FEF75% have significant positive correlation with BMI of underweight. But in normal subject’s significant positive correlation between FEV1/FVC, FEF25-75%, PEFR, PIFR, FEF25%, and FEF50% with BMI were observed. In overweight there were significant negative correlation observed between FEV1, FEF25-75%, PIFR and FEF50% with BMI. Conclusion: Our study showed that clear association was found between pulmonary function parameters and BMI in females with non-obstructive airway disease
