Waist circumference and waist-hip ratio as a predictor of respiratory risk factor

Divyashree, Suhas Y Shirur, Veena H Chandregowda.

Abstract
Background: The prevalence of Abdominal Obesity as well as of Generalized Obesity are high in India. Obesity can directly alter respiratory physiology through a variety of processes and can lead to reduction in lung function. The quantity and location of body fat alter the impact of obesity on pulmonary function. Waist circumference (WC) links to intra-abdominal and subcutaneous fat and it is a better scale of intra-abdominal fat.

Aim and Objectives: (1) To determine the effect of anthropometric parameters like WC, waist-hip ratio (WHR) on timed vital capacity in adult. (2) To determine the difference in timed vital capacity between males and females.

Materials and Methods: 150 apparently healthy adults aged 20–40 years were selected for the study. WC, Waist-hip ratio were measured. Pulmonary functions such as Forced Vital Capacity, Forced Expiratory Volume in one second, (FEV1/FVC%) were recorded using Computerized Spirometer (RMS HELIOS 401). Data were statistically analyzed by unpaired t-test, Karl Pearson’s coefficient of correlation test, statistical significance was considered for P < 0.05.

Results: FVC, FEV1 were significantly declined in both male and female subjects in the group II compared to group I in terms of both WC and WHR. FVC, FEV1were significantly higher in males when compared with females. Significant negative correlation observed between FVC and FEV1 values with Group II of WC and WHR.

Conclusion: To conclude obesity even in the absence of specific pulmonary disease, alters the pulmonary function, that can lead to long-term consequences. Regular exercise, yoga, pranayama help to reduce weight and improve breathing by strengthening respiratory muscles.

Key words: Waist Circumference; Waist Hip Ratio; Timed Vital Capacity
