Abstract

Sastav tijela je puno bolji pokazatelj stupnja uhranjenosti nego indeks tjelesne mase, zato što pretilost nije definirana kao povećana tjelesna masa nego kao povećani udio masnog tkiva u tjelesnoj masi. Cilj ovog rada bio je usporediti Bland-Altman metodom vrijednosti udjela masnog i mišićnog tkiva izmjerenih BIA-ACC uređajem te dijagnostičkom vagom OMRON BF500 metodom bioelektrične impedancije u studentske populacije. U istraživanju je sudjelovalo 139 studenata (124 ţene i 15 muškaraca) Prehrambeno-biotehnološkog fakulteta Sveučilišta u Zagrebu. Dobiveni podaci su analizirani i grafički obrađeni u programu IBM SPSS Statistics 22.0. Spearmanov koeficijent korelacije korišten je za procjenu povezanosti između dviju metoda za procjenu sastava tijela, a Bland-Altman metoda za procjenu suglasnosti između njih. Prema rezultatima Bland-Altman analize može se zaključiti da su metode suglasne za osobe s adekvatnim sastavom tijela, ali u osoba s prevelikim ili premalim udjelom masnog tkiva te s velikom mišićnom masom može doći do pogreške prilikom mjerenja.

Abstract (english)

Body composition is a much better indicator of classification of weight than the body mass index because obesity is not defined as increased body weight but as increased proportion of adipose tissue in body mass. The aim of this study was to compare by Bland-Altman method the values of adipose and muscle tissue content measured by BIA-ACC device and diagnostic scale OMRON BF500 by bioelectric impedance among student population. The study involved 139 students (124 women and 15 men) of Faculty of Food Technology and Biotechnology, University of Zagreb. Collected data were analyzed and graphically processed in IBM SPSS Statistics 22.0. The Spearman correlation coefficient was used to estimate the correlation between the two methods for estimating body composition and the Bland-Altman method was used to estimate the agreement between them. Based on the results of Bland-Altman analysis, it can be concluded that the methods are consistent for people with adequate body composition, but in people with too much or too little adipose tissue and with a large muscle mass an error may occur during the measurement.
