Abstract

Background: The Prevalence and severity of obesity in young adult women is dramatically increasing worldwide. Along with other organs respiratory system is also compromised. Obesity is likely the cause of pulmonary function decline which is linked to early morbidity and mortality. The study was undertaken to assess the Static pulmonary function tests in obese and non -obese young adult women of Hubli city of 18-30 years age group, randomly selected from the general population satisfying inclusion and exclusion criteria. Aims and Objectives: The purpose of this study was to compare Static Lung Volumes and Capacities parameters in obese adult females and non-obese adult female subject, to evaluate the impact of obesity on Pulmonary Function Test Parameters. Materials and Method: Pulmonary Function tests (PFTs) of 50 normal, healthy, non-obese females and 50 healthy but obese females, age group 18-30 years of Hubli city were determined and were compared. Criteria for obesity in our study taken were according to WHO criteria of BMI. The pulmonary function test was carried out with computerized Spirometer Eazy on-PC model. Static Lung Volumes and Capacities parameters were used as measure of lung function. Results: In our study Obese females had VC (litres)of 2.37±0.65, ERV (litres) of 0.4±0.58 , IRV (litres)of 1.11±0.67 , IC(litres) of 1.76±0.2 , TV(litres)of 0.64±0.3 compared to non-obese Females. Static pulmonary function test parameters in Young adult females showed a negative correlation with obesity which was statistically significant Conclusion: In our study it was found that obesity had an inverse association with the Static lung volumes and Capacities parameters as indicated by decrease in VC, IRV, IC, TV. Hence from the present study we conclude that static lung volumes and capacities parameters of obese adult females were significantly reduced when compared to the normal weight counterparts
