Abstract

Introduction: Epidemiological studies have provided evidence that exposure to indoor particulate matter (PM10) and indoor volatile organic compounds (VOCs) may decrease the lung function among children. Objective: The objective of this study was to determine the exposure of indoor PM10 and indoor VOC and its association to the preschool children respiratory health in urban and rural area in Selangor. Material and method: Purposive sampling method was used where 96 selected respondents from both urban and rural were chosen. Personal and sociodemographic background, and other related information were adopted from standardized and structured questionnaire of American Thoracic Society. Personal air sampling pumps were used to measure indoor PM10 in the respondents' house while PbbRAE Portable VOC Monitor is used to measure the indoor VOC. Lung function was measured using Chest Graph Spirometry. Result: The indoor PM10 level at home is higher in the urban area with mean (76.61±17.53 ug/nr') compared to the rural area (48.37±8.33 ug/rrr') with p<O.OOl. Indoor VOC indicate a highly significant difference (p<O.OOI) between urban 0.083 (0.025) ppm and rural area 0.035 (0.020) ppm. Study also showed that the lung function; FVC% predicted(Z=- 4.514, p<O.OOI)and FEV1% predicted(Z=-5.509, p<O.OOI)were significantly lower in the rural area than the urban area. The prevalence of abnormal FVC% predicted among urban group was 75% and the rural group was 37.5%. The prevalence of abnormal FEV1% predicted among urban group was 75% and the rural group was 33.3%. There was an inverse correlation for PM10 concentration between the children's lung function; FVC% predicted(r= - 0.209, p<0.041) and FEV1% predicted(r= - 0.258, p< 0.001). For VOCs, there were no correlation between VOCs and children's lung function. Respiratory symptoms which include cough (X2=40.2, p<O.OOI), phlegm (X2=37.76, p<O.OOI) and wheezing (X2=50.35, p<O.OOI) were significantly higher among children in the urban area compared to the rural area. There was significant relationship between high PM10 levels for cough (X2=4.547, p<0.033) and chest tightness (p<0.022). There was no significant relationship between respiratory symptoms and VOCs concentration. Conclusion : From the result, it can be conclude that PM10 does affect the abnormality of lung function and increased the respiratory health symptoms. Keywords: Children, lung function. PM10, VOCs, respiratory symptoms
