Abstract

Background: Obesity has become a global epidemic. The Prevalence and severity of obesity in young adult females is increasing worldwide. Along with other organs respiratory system is also compromised. Since the static lung volumes that are obtained by Spirometry are insufficient to conclude on whether the ventillatory abnormality is an obstructive one or a restrictive pattern, dynamic or forced Spirometry is performed. Hence the present study was done to know the Impact of obesity on Dynamic Lung Function Test in young Adult Females. Aims and Objectives: 1. To Compare Dynamic Lung Function Test in obese adult females and non-obese adult female subject. 2. To evaluate the impact of obesity on Dynamic Lung Function Test. Materials and Method: Dynamic 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 obtained and were compared. Criteria for obesity in our study were taken according to chart provided by WHO for categorization of BMI. The Dynamic Pulmonary function test was carried out with computerized Spirometer Eazy on-PC model. Dynamic Lung Function Test parameters were used as measure of lung function. Results: The obese females had FVC ( litres )of 2.31±0.41 whereas corresponding values in non-obese 2.87±0.66. There was statistically highly significant differences between two groups (p<0.01) .The obese females had FEV1 (litres ) of 1.94±0.38 whereas corresponding values in non-obese was 2.4±0.61. There was statistically highly significant differences between two groups (p<0.01). The obese females had FEV1/ FVC(litres ) of 0.83±0.08 whereas corresponding values in non-obese was 0.84±0.11, obese females had less FEV1/FVC ratio compared to non-obese females. Conclusion: In the present study Dynamic Lung Function Test parameters FVC, FEV1 values were significantly reduced in obese females compared to non-obese females, also obese females had lower FEV1/ FVC ratio compared to non-obese females. Obesity had significant impact on Dynamic Pulmonary function tests in young adult females of Hubli city.
