COMPARATIVE ANALYSIS OF LUNG AGING PROCESS IN OBESE AND NONOBESE ADULTS IN A TERTIARY CARE HOSPITAL

Introduction: Obesity has a mass loading effect of adiposity on the thoracic cage and abdomen can have an effect on respiratory mechanics leading to decreased chest wall and lung compliance, decreased pulmonary gas exchange, limitations in exercise capacity and altered pulmonary physiology.The aim of the study is compare the influence of obesity in lung aging process in a tertiary care hospital in South India. Methods: A hospital based prospective comparative study was conducted in Department of Respiratory Medicine, Chettinad Hospital & Research Institute for which about 150 students were recruited. Results: The study revealed that lung age increases 15.85 % with statistical significance (p=0.001) eventually compared with the chronological age. But in the non-obese group there were no significant changes.Conclusion:In present study it has been concluded that obesity with increasing BMI have direct effect on lung aging process along with reducing lung volumes leading to airway/restrictive lung disease in their future.
