Background: Air pollution is one of the world's most serious environmental problems. Air pollution has many negative health effects on the general population, especially children, individuals with underlying chronic disease, and the elderly. The aims of this study were to evaluate the effects of traffic-related pollution on the exacerbation of asthma and development of respiratory infections in schoolgoing children in Agra, suffering from asthma compared with healthy subjects, and to estimate the association between incremental increases in principal pollutants and the incidence of respiratory symptoms. Materials and Methods: We enrolled 702 children aged 6–18 years in this prospective study. A total of 342 children with asthma and 360 healthy subjects were monitored for 6 months from September 2013 to February 2014. Clinical data were combined with the results obtained using an air pollution monitoring system of the five most common pollutants. A total of 328 children with asthma and 345 healthy subjects completed follow-up. Results: Children with asthma reported significantly more days of fever (P <0.001) and cough (P < 0.001), episodes of rhinitis (P = 0.087), asthma attacks (P < 0.001), episodes of pneumonia (P < 0.003), and hospitalizations (P = 0.01). In the asthma cohort, living close to the street with a high traffic density was a risk factor for asthma exacerbations (odds ratio [OR] = 1.79; 95% confidence interval [CI], 1.13–2.84), whereas living near green areas was found to be protective (OR = 0.50; 95% CI, 0.31–0.80). Conclusion: There is a significant association between traffic-related pollution and the development of asthma exacerbations and respiratory infections in children suffering from asthma. These findings suggest that environmental control may be crucial for respiratory health in children with the underlying respiratory disease.
