Type of Fuel Consumed and Frequency of Lorry Passing Associated with Allergic Rhinitis and Asthma Symptoms in Children

Allergic diseases are prevalent in children and their prevalence and severity are different in dissimilarareas of the world. many studies have been carried out regarding the inspection of the causativeenvironmental factors such as air, foods and environmental allergens. in this study, using the isaacstandardized method, the relation between asthma and allergic rhinitis symptoms with the kind of fuelconsumed at homes and the frequency of lorry passing through the streets next to the houses in 3000children aged 6-7 years and 3000 children 13-14 years was investigated. the results indicated that inthe children aged 6-7 years, the prevalence of asthma and allergic rhinitis had a meaningful relationwith the type of fuel consumed at homes (p<0.05), so that the less pollutant fuel resulted in lesssymptoms. the evidence suggested that in both age group, when there was lorry passing all day long,there were more wheezing and allergic rhinitis symptoms, and the difference was meaningfulregarding allergic rhinitis (p< 0.05). the study reveals that indoor and outdoor air pollution isassociated with increase in the prevalence of allergic diseases in children. therefore, it seems that thesetypes of air pollution can be a cause of increase of the allergic cases in childhood.
