- Abstract
Lung function test results of children with respiratory diseases were usually compared with the reference values from equipment software. In this cross-sectional study the lung function of children with respiratory problems was compared to the specific reference values for healthy Estonian children. The description of the group was made by univariate analyses. When comparing the observed data with the Estonian reference values, standardized residuals and the statistical significance of differences by the Student t-test were calculated. SR for the observed forced vital capacity and the peak expiratory flow data of boys and girls mostly fit into ±2 when the children are shorter than 140 cm. The taller (older) the child was, the more observed forced vital capacity data underfitted the reference values. SR of the observed forced expiratory volume in one second showed the deviation from ±2 mostly into the negative side, larger in boys than in girls. SR for the observed forced expiratory flows when 50% of FVC remains to be exhaled (MEF50) rarely deviated into the positive direction. The deviation turned from ±2 into the negative direction when the height of boys and girls exceeded about 120 cm. SR for the observed forced expiratory flows when 25% of FVC remains to be exhaled (MEF25) showed an excess of residuals on the negative side, especially among girls. Statistically significant differences among observed and predicted lung function values were found in all the parameters but not for FEVC and FEV1 in girls by the Student t-test. The decreased lung function indices of children turned to medical care with respiratory problems were established when comparing their data with the healthy Estonian children.
