The Effects of Body Mass Index on Respiratory Parameters

Abstract

Objective: To assess the correlation of body mass index (BMI) and respiratory parameters determined by spirometry.

Methods: A cross-sectional descriptive study was conducted at Medicine OPD of GP Koirala National Centre for Respiratory Disease, Dulegaunda, Tanahun from December 2021 to February 2022. A total of 95 underweight, normal, overweight, and obese participants, aged between 40 to 73 years were included in the study. BMI was determined by measuring the height and weight of individual patients. Spirometry was performed to determine different respiratory parameters.

Results: Mean age of participants was 56.7 ± 16.4 years with female population constituting 54% of the total population. Most of the study population were of normal weight (n=40) and pre-obese (n=41). An insignificant correlation between BMI and respiratory parameters was determined.

Conclusion: An insignificant correlation between BMI and respiratory parameters was determined in this study.
