Association of Ambient Air Quality with Pulmonary Function of Youngster Footballers

Air pollution has remained a major health concern in Kolkata. The present study was carried out to analyze the association between the levels of air pollutants and pulmonary function of youngster footballers living in two different air pollutant zones of Kolkata, West Bengal. Air pollution data of the two ambient air quality-monitoring stations located at Rabindrabharati and Victoria Memorial was collected for the period from January 2012 to March 2012. Study was conducted on two hundred and twenty boys of the age range 14-16 years living within 3km radius of the two monitoring stations. Sample consisted of 60 footballers (30 from Rabindrabharati and 30 from Victoria Memorial) and 160 sedentary boys (80 from Rabindrabharati and 80 from Victoria Memorial). They were investigated for their spirometric lung functions by the method and technique recommended by American Thoracic Society. Results were expressed as mean ± SD and independent samples T test was conducted to compare between two groups. Results revealed that particulate matter (PM10), oxides of sulfur (SO2) concentrations were significantly higher in Rabindrabharati zone, whereas no significant differences were noted in oxides of nitrogen (NO2) and carbon monoxide (CO) concentrations though values were higher at Rabindrabharati than Victoria Memorial. Forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), forced mid expiratory flow (FEF25-75%), maximum voluntary ventilation (MVV) were significantly lower both in footballers (P<0.05) and sedentary boys (P<0.01) of Rabindrabharati zone. Exposure to high air pollutant concentration might be associated with reduced pulmonary function in both sedentary and trained boys in spite of the fact that regular participation in training program may improve pulmonary function.
