ASSOCIATION OF BODY MASS INDEX WITH LUNG FUNCTION IN PRE- PUBERTAL GIRLS IN VADODARA DISTRICT

Abstract

Introduction: Among the various investigations available, pulmonary function test (PFT) is a one of the important tool for the assessment of pulmonary function. There must be differences in reference values in India between different state, different region for spirometric parameters.

Methodology: The present study was conducted among normal healthy pre pubertal girl in Vadodara region. The study was conducted among pre pubertal girls (10-12 yrs). Standard anthropometric measurements weight (kg), height (cm), was measured in a beam balance. Minimum three readings were given and best of the three was chosen for analysis, based on standardization of spirometry study based on ATS/ERS task force series and various other studies.

Results: Mean age of the participants was 11.36 (±0.69) years. Similarly mean height, weight, BMI and BSA was 134.8(±8.91) cm, 28(±5.9) kg, 15.29(±2.02) (Kg/m²), and 1.02(±0.13) (m²) respectively. There were 27(60 %) participants with BMI <18 and 18(40%) participants with BMI >18. There was significant statistical association between BMI and FEV1 (%), FEV1/FVC (%), PEFR (%) (P < 0.05).

Conclusion: There is significant relation between pulmonary function and BMI in pre pubertal girls. As BMI increase lung function tends to be decrease as compared to those who have low BMI.
