Abstract

Introduction: A cross sectional comparative study was carried out on children from a school less than 1km from paddy fields at Tanjung Karang, Selangor Darul Ehsan. Objective: The objective of this study was to find the association between respirable particulates (PM1o) air concentration and the children respiratory health. Material and Method: Seventy seven children from the school located near to paddy fields and exposed to PM10 concentration were randomly selected from the class name list as exposed group while 72 children from the school located further away were also selected randomly as a comparison in this study. Questionnaires were given to the parents to obtain the background information on their children and respiratory history. Children's lung functions were measured by Chest Graph Spirometer and the individual PM10 levels were measured by Gillian personal air sampler. Result: The individual PM10 levels showed a significantly higher (64.71 µg/m3) in the exposed group than the comparative group (43.14 µg/m3) (p<0.001). The findings also showed the lung functions; FVC% predicted (p<0.001) and FEV,% predicted (p<0.001) in the exposed group were significantly lower than the comparative group. The prevalence of abnormal FVC% predicted among exposed group was 66.8% and the comparative group was 31.2%. The prevalence of abnormal FEV,% predicted among exposed group was 66.8% and 33.3% for comparative group. There was an inverse correlation between the children's lung function; FVC¾ predicted (p<0.001) and FEV1% predicted (p=0.001) with PM10 concentration. Respiratory symptoms such as cough (p=0.005), phlegm (p=0.016) and wheezing (p<0.001) were significantly higher in the exposed group than the comparative group. There were significant relationships between PM10 level with cough (p=0.025) and wheezing (p<0.001). Conclusion: From the results, PM10 significantly influenced the exposed children's respiratory health in term of the abnormality of lung functions as well as increment of the reported respiratory symptoms.
