Abstract

Purpose: The purpose of our study is to provide useful information for measurement
methods of childhood obesity and to provide clinical significance of bioelectrical
impedance analysis.
Methods: We measured height, weight, waist to hip ratio, skinfold thickness and
bioelectrical impedance from 206 elementary students in Kwangju from May to July
1997.
Results: In males; 1) There were statistically high correlations between triceps
skinfold thickness and body mass index (BMI), percentage of body fat (%BF), weight,
Rohler index (RI), total fat weight (TFW), waist to hip (W/H) ratio, height, lean body
mass (LBM) (all, p<0.001). 2) There were statistically high correlations between
subscapular skinfold thickness and BMI, RI, weight, %BF, TBW (all, p<0.001). 3) There
were statistically high correlations between %BF and BMI, triceps skinfold thickness, RI,
TFW, subscapular skinfold thickness, weight (all, p<0.001).
In females; 4) There were statistically high correlations between triceps skinfold
thickness and BMI, weight, LBM, height, %BF (all, p<0.001). 5) There were statistically
significant correlations between subscapular skinfold thickness and BMI, weight, LBM,
RI, height. 6) There were statistically high correlations between percentage of body fat
and BMI, RI, triceps skinfold thickness.
The percentage of body fat according to the bioelectrical impedance analysis highly
correlated with that calculated by skinfold thickness in males (r=0.57, p<0.01) and in
females (r=0.30, p<0.01).
Conclusion: The results of our study suggests that bioelectrical impedance analysis is
a useful method of estimating body fat in the childhood obesity.
