Summary: | Introduction: In India, undernutrition coexists with obesity,
thus demonstrating a “double burden of the disease.” The
effect of the increased BMI and the body fat percentage on the
pulmonary functions has been studied extensively. The effect of
undernutrition and mild weight gain on the pulmonary functions
needs attention.
Objectives: The aim of this study was to investigate 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: 180 students who consisted of 90
boys and 90 girls in the age group of 18 to 21 years, who were
in three BMI ranges were enrolled. They were classified into
underweight, normal weight and overweight groups according
to the WHO guidelines. The body fat percentage was measured
by using the bioelectric impedance method and FVC, FEV1
and
FEF25-75 were assessed by using MIR-SPIROLAB-II as per the
ATS guidelines.
Results: The mean values of FVC and FEV1 were less in the
underweight and overweight subjects and the difference was
significant across the BMI ranges. 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. BMI as well as the body fat
percentage had a significant negative correlation with FVC and
FEV1
in the overweight group. A significant positive correlation
was observed between BMI, body fat percentage and FCV
and FEV1
. Body fat percentage had a stronger correlation than
BMI. FEF25-75 had a strong negative correlation with the body fat
percentage only in the overweight group. |
