Abstract :

ABSTRACT: The present study was planned to study correlation between pulmonary function tests (PFT’s) and BMI in young adult males. DESIGN: 6 months cross–sectional study Methods: The selected group of subjects were categorized into normal weight and overweight based on BMI. Before proceeding to the test a detailed clinical history was elicited followed by detailed clinical examination to rule out any illness/underlying disorders. RESULTS: In the normal BMI group the mean of FEV1 was 3.19 ,it was 2.58 in the overweight group and was 2.41 in the obese group. FEV1/FVC% in normal BMI group was 95.92, it was 94.87 in the overweight group and was 94.69 in the obese group. In the normal BMI group, the mean for PEFR was 429.12, it was 367.86 in the overweight group and was 316.32 in the obese group. CONCLUSION: Obesity influences the respiratory function enhancing dyspnoea and increasing both cardiac load and respiratory muscle fatigue of the thoracic wall and the diaphragm due to the higher pressure exerted by intra abdominal adipose accumulation. In the present study, clear association was found between indices of spirometry i.e. FVC, FEV1 and PEFR and increasing BMI in overweight and obese study group of young adult males as compared to young adult males of normal BMI.
