A Comparative Study of Maximum Voluntary Ventilation in Overweight & Obese Adult Males

Abstract

Introduction : Obesity is a global ep idemic. It is characterized by excessive fat accumulation in the body, which affects multiple organs including the respiratory system by various mechanisms. The Prevalence and severity of obesity in young adults is increasing worldwide. The lung functions can be measured by spirometry. The Maximum Voluntary Ventilation test evaluates the respiratory endurance and is influenced by the lung and chest compliance, control of breathing and airway resistance. Aim : The purpose of this study was to compare the Maximum Voluntary Ventilation parameter in obese, overweight and non-obese adult males and to evaluate the impact of obesity on MVV. Methodology: A cross-sectional study was conducted among seventy-six adult males of Western Rajasthan in the age group ranging 18-25 years were performed on a spirometer, who were further divided into three groups based on Body Mass Index (criteria for Asian Indians) two groups based on WHR (waist-hip ratio). The observed data were statistically analyzed using ANOVA, Post-Hoc test and Linear Regression test. Results: In our study , we found a significant reduction in MVV values in overweight and obese. The obese males had MVV (L/Min) of 68 ± 10.80; overweight males of 78.77 ± 17.93 whereas corresponding values in non-obese were 112.61 ± 19.42. According to ANOVA, a highly-significant (HS) difference among the three groups (p˂0.01) . The multiple regression method reveals a negative correlation with MVV which is highly-significant (p<0.01) . Conclusion: Our study concluded that the impairment of Pulmonary Function is strongly associated with adult overweight and obese males. The reduction in BMI by reducing weight can reduce morbidity.
