Normal Predicted Values of Pulmonary Function of the Primary School Children in Rural Area and Sensitive Index of Respiratory Symptoms / 예방의학회지

ABSTRACT

Pulmonary function tests were conducted on 815 healthy primary school children (390 males and 425 female) in rural area using Collins Survey Spirometer (warren E. collins, Inc, U. S. A.) with X-Y Recorder. Respiratory symptoms(cough, sputum, sore throat, chest pain, chest tightness, dyspnea, coryza) were surveyed by the interviews. Multiple regression analysis and regression diagnostics were done for prediction equations of FVC, FEV1, PEFR and FEF25-75% . FVC, FEV1, PEFR and FEF25-75% values in 3 groups of children classified by the number of symptom were compared each other through standard variable value. FVC, FEV1, PEFR and FEF25-75% showed highly significant correlation with age, height and weight. Prediction equations for FVC, FEV1, PEER, FEF25-75% are functions of height only in both male and female children aged between 6 and 12 years old. PEFR showed a significant difference related with the number of symptom in female. These results suggest that the PEFR is sensitive PFT parameter in this study.
