ABSTRACT
Obesity is a global health hazard. As standards of living are continuing to rise, weight gain and obesity are posing a growing threat to health in countries all over the world. These obese individuals are at increased risk of morbidity and mortality because of its relationship with various metabolic disorders. It is also known to cause alterations in pulmonary functions, so the present study was planned to assess the effect of obesity on pulmonary function tests in young adult females of 18 to 25 years. Based on body mass index (BMI) participants were divided in to two groups. Both groups were age and physical activity matched. Pulmonary function tests were recorded using computerized spirometry. Results when analyzed statistically using students “t” test showed that there was a significant decrease in expiratory reserve volume in obese individuals compared to controls. Other tests were not significant. This result shows that obesity has an impact on respiratory functions even in younger age group hence we have to safeguard against the hazards of obesity by taking corrective steps through our health programs.
