Abstract
Pulmonary functions are affected by variables like age, sex, height, weight, and geographic location. Our
study aims to establish predicted equations for pulmonary functions in normal South Indian adolescent
population. 400 subjects were grouped into pre & peripubertal (10-14 years) and pubertal (15 to 18 years)
age categories. Anthropometric data collected, PFT assessed using portable data logging Spirometer MIR
II. Mean FVC and FEV1 values were 2.80 L, 2.49 L in boys and 2.34 L, 2.12 L in girls respectively. Predicted
equations for both adolescent age groups were generated by using linear regression analysis. PFT were
significantly different in both age categories in boys and girls. PFT increased with increasing age and
significantly correlated with the anthropometric parameters. Region specific and age specific predicted
equations for PFT are generated from this study.
