The aim of this study was to evaluate some antropometric and clinical parameters in children with cystic fibrosis. Studies involved 34 patients with cystic fibrosis: 13 girls (38.24%) and 21 boys (61.76%) in the age of 6 to 18 (x +/- SD = 12 +/- 3,12 lat).
Variables: antropometric measurements (height, body weight, circumference of the chest), spirometry, 6 minute walkin test (6MWT), pulse oximetry had been measured for 4 consecutive years. Significant difference was found in dynamics of change of body weight in boys with cystic fibrosis in comparison with healthy boys in the age: 9-11 and 12-14 ( p< 0,001 and p< 0,03 respectively). Analogous differences were found in: dynamics of change of height in girls with cystic fibrosis in comparison to healthy girls in the age 12-14 (p<0.05) and in boys with cystic fibrosis in comparision to healthy boys in the age 9-11 (p< 0.001). Significant changes were observed in values of FEV1 and FVC EX in consecutive 4 years of observation (p<0.002) and p<0.002 respectively). Loss of saturation in subjects during 6 MWT was significant (p< 0,001); (x=2.69%). The mean of oxygen arterial blood saturation was 96.44% (initial level); 93.75% (post-test levels). There was correlation between the post-test level of saturation and circumference of the chest in girls with cystic fibrosis.
