Abstract

Introduction: Central obesity is an emerging public health problem in young adults which compromises lung mechanics. Conicity Index (CI) is a simple anthropometric measure to assess central adiposity. The concept of lung age relates to a person’s current lung function at which his/her lung function would be considered abnormal in relation to the present actual age.

Aim: To determine the effect of central obesity by CI on lung age in young adults.

Materials and Methods: A total of 319 young adults in the age group 18-25 years were recruited for this cross-sectional observational study. Written informed consent and institutional ethical clearance (IEC) approval were obtained. Anthropometric parameters were measured and CI was calculated using the following formula: CI = Waist Circumference (WC) (m)/ [0.109 Xv {Bodyweight (kg)/ Height (m)}] where 0.109 is a constant. Spirometry was performed and all the lung volumes and capacities were obtained.

Results: There was a significant increase in mean values of CI in obese young adults compared to non obese (1.36±0.15 and 1.16±0.08, p<0.001). The effect of central obesity on lung age in young adults was compared using an independent t-test. Mean of lung age was significantly higher in centrally obese young adults compared to non obese (24.63±3.33 and 21.30±2.6, p<0.001) which was statistically significant.

Conclusion: Lung age is significantly increased in centrally obese young adults compared to non obese. Hence, lung age can be used as a potential psychological tool to show an individual with central obesity that there is premature aging of their lungs.
