Research on Pulmonary Functions and It s Influence Factors in Korean and Chinese Schoolchildren

To evaluate the health effects caused by air pollution, we conducted a preliminary study on pulmonary function and it s related factors as a first year s work of a cooperative research project between Korea and China. 200 schoolchildren, grade 3 to 6, from two schools on Beijing and Helong in China were recruited to perform the pulmonary function test(PFT). A questionnaire concerning medical history and potential influence factors(such as passive smoking, heating or cooking fuels, use a stove or keep a pet in indoor, crowding within a room, and family income) was filled out by children s parents. Regression analysis was utilized to determine which potential influence factors were significantly correlated with PFT measure(FVC and FEV1). We also compared the pulmonary functions of Chinese children with those of other studies of Korean children. The results of regression analysis between potential influence factors and PFT measure were not statistically significants. As the results of comparison of the pulmonary functions(controlled by height, weight, and age) of Chinese children with those of other studies of Korean children, FVC and FEV1 were lower in Korean children(FVC 0.015L, FEV1 0.026L in boys; FVC 0.128L, FEV1 0.136L in girls) compared with Chinese children. In this study, we could not present causation between air pollution and health effect because of some limitations(such as absent of air pollution data), but the results will be used usefully for design of next year s study which is to assess acute effect of air olution(especially, PM10, PM2.5) on pulmonary function.
