The objective of this study was to determine the effect of different parameters on a predictive model of pulmonary function for elementary school children in an area of low air pollution in Taiwan. Healthy children aged 7 to 12 years from three elementary schools in low-air-pollution areas (Da- Chen, Mai-Liau and Tai-Si) participated in the study. A total of 836 children (423 boys and 413 girls) were included in the study. During summer vacation, each child underwent a physical examination including a screening spirometry. A questionnaire regarding respiratory symptoms and indoor air pollutants was also completed by the children's parents. Air monitoring showed that the levels of outdoor pollutants were relatively low. Multiple linear regression analysis was performed with FVC (forced vital capacity) and FEV1 (forced expiratory volume in 1 sec) as dependent variables. Gender, age, height, weight, technician and indoor air pollution parameters were the independent variables. The results showed that gender, height, weight and technician were the most significant variables for predicting FVC and FEV1. The various indoor air pollution parameters seemed to have no influence on the pulmonary function of children, except that mildew in bedrooms mildly decreased FEV1. Regression analysis showed that all the pulmonary function parameters measured had a positive correlation with height, whereas weight correlated only with certain parameters. Because both indoor and outdoor air pollution was relatively low, we suggest that this model could be used as a basic predictive model of pulmonary function for elementary school children in Taiwan.
