Comparison of Two BIA Devices Assessing Body-Fatness in Middle School Students

Article excerpt

The validity of body composition assessment tools for school-aged children is an important applied research topic. Previous studies found the mean differences in percent body fat (%BF) values measured from foot-to-foot bioelectrical impedance analysis (F-BIA) and hand-to-hand (H-BIA) in Japanese men and American college male students. This investigation was to examine if there had differences in %BF estimates measured by two analyzers in middle school students. Participants were the sixth-grade students (N = 146). The study was explained and the informed consent was signed before testing. Omron Body Fat Analyzers were used to measure %BF. Participants were measured following the manufacturer instructions and other guidelines. Pearson's method was used to examine correlations. Differences in variables were tested using t test. Significant level was set at p < .05. Values are presented as means and standard deviations. Data were analyzed using SPSS for Windows. Participants' mean age was 11.91 [+ or -] 0.43 years. The results indicated a significant mean difference in %BF estimated by two devices: 29. …
