- Abstract
INTRODUCTION: Children are vulnerable to the effects of air pollution because of immature organ system and immune system. Air pollutants can lead to both upper and lower respiratory tract symptoms. METHODOLOGY: Adolescents in the age group of 10-19 years children from residential areas with established maximal and low pollution levels as reported by State Pollution Control Board were included in the study using age-, sex-, weight-, and height-matched case-control study design. For the assessment of respiratory dysfunction, the values of forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), FEV1/FVC, and forced expiratory flow (FEF) 25%-75% were included in this study. Odds ratio with 95% confidence interval was calculated to ascertain the strength of association. RESULTS: The distribution of abnormalities for a restrictive pattern in males in polluted group was 42% as compared to 29% in low polluted group (P = 0.007). The mean values of pulmonary function parameters FVC, FEV1, FEV1/FVC, and FEF 25%-75% (expressed as percentage of predicted values) were compared in two groups, a deficit of approximately 4.5%, 6%, 1.06%, and 3.4% was observed in males versus 4.9%, 6.3%, 2.44%, and 2.4%, respectively for females. CONCLUSION: There is a statistically significant difference in the pulmonary functions in the polluted versus less polluted areas with the children being affected in a harmful manner in the former areas.
