ASSOCIATION BETWEEN BODY MASS INDEX (BMI), BODY FAT PERCENTAGE AND PULMONARY FUNCTIONS IN OBESE, OVERWEIGHT AND NORMAL WEIGHT ADOLESCENTS
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2018, Vol 7, Issue 44
Abstract
BACKGROUND Abdominal obesity may influence the lung function through a mechanism that restricts descent of diaphragm and limits lung expansion compared to overall adiposity, which may compress the chest wall. Multiple measures of adiposity showed significant inverse relationship with both spirometry and static lung volumes. However, only a few studies have considered the associations between body fat distribution, body composition and lung function in young adults. The aim of the study was to find out whether there was any correlation between the Body Mass Index, Body Fat Percentage and FVC, FEV1 and FEF25-75 in underweight, normal weight and overweight adolescents. MATERIALS AND METHODS 158 students consisting of 90 boys and 68 girls in the age group of 18 to 19 years were included in the study. They were classified into underweight, normal weight and overweight groups according to WHO guidelines. The body fat percentage was measured by using Harpenden skinfold caliper and FVC, FEV1 and FEF25-75 were assessed by using RMS Helios 702 electronic spirometer. RESULTS The FEF25-75 values were low in the overweight than in the normal weight subjects. FVC, FEV1 and FEF25-75 had a negative correlation with BMI and the body fat percentage in males. The underweight males had a positive significant correlation between BMI, body fat percentage and FVC, FEV1 and FEF25-75. In females, only FEF25-75 had a significant correlation with BMI and the body fat percentage. CONCLUSION There was a significant difference in the FVC, FEV1 and the FEF25-75 values between the underweight, normal weight and the overweight subjects. Body fat percentage had a stronger correlation than BMI.
