Background: This study has been performed to compare the pulmonary functions of healthy adolescents studying in schools situated in highly polluted areas with those studying in schools of low polluted areas of south western Punjab.

Methods: This study was conducted in various schools located at Faridkot and Bathinda city. These places had been identified by the Punjab Pollution Control Board (PPCB) as having low and high air pollution levels respectively. Study Population divided into two groups that is Group A: 300 children from schools situated in Bathinda city. Group B:  301 children from schools situated in Faridkot city. Spiro Excel spirometer was used, and following parameters were obtained: FVC, FEV₁, FEV₁% (relation of FEV₁ to FVC), PEFR, FEF25-75%.

Results: FVC was low in males and females in the high polluted group as compared in the low polluted group (p = 0.042; significant; males) (p = 0.039; significant; females). FEV₁ was low in males and females in high polluted group as compared in low polluted group (p = 0.003; significant; males) (p = 0.026; significant; females). In this study only, males showed a significant fall in mean percentage of FEF25-75%. PEFR was low in males in high polluted group as compared to that in low polluted group (p = 0.007; significant) while in females it was insignificant.

Conclusions: It is concluded that in South Western Punjab, air pollution has detrimental effect on pulmonary functions (FVC, FEV₁, FEV₁%, FEF25-75% and PEFR) in healthy adolescents.


Pulmonary Function, FVC, FEV1, FEV1 %, FEF₂₅₋₇₅%, PEFR.
