Object: Obesity is defined as $quot;heperaccumulation of bodyfat$quot;. So in diagnosis of obesity, the accurate measurement of body fat is very important. The recent development of bioelectrical impedance analysis(BIA) method made it possible to analyze percent body fat more easily. We performed this study for two purposes. The first is to evaluate the precision error of percent body fat measurement by bioelectrical impedance analysis(Inbody 2.0,Biospace Seoul Korea) method. The second is to evaluate the correlation between densitometry and bioelectrical impedance analysis(BIA), body mass index(BMI) and Broca's method in body composition analysis. Method: To evaluate the precision error of BIA method, 7 health subjects(M;3, F;4) were selected. Percent body fat measurement by BIA rnethod was performed one time a day for 10 days. To evaluate the correlation between densitometry and BIA(Inbody2.0, Seoul Korea), BMI, and Broca method, 23 health subjects(M;10, F;13) were se)ected. To these subjects we measured height, weight, and percent body fat by RIA and densitometry. The Brozek's formula was used for percent body fat calculation by hydrodensitometry method. To assess the precision error of the measurement, we performed descriptive analysis by using SPSS statistic package. To assess the correlation, we performed bivariate correlation analysis and age controlled partial correlation analysis. Results: The precision error of BIA method in percent body fat measurement was 3.4%. The precision error of densitometry method was 3.0%. In bivariate correlation analysis, there were statisticaily significant correlation between densitometry and B1A method(r=0.85, p$lt;0.001). In bivariate correlation analysis, there were no statistically significant correlatton between densirornetry and BMI, BROCA method. In age controlled partial correlation analysis, there were statistically significant correlatton between densitometry and BIA, BMI and Broca's method. The correlation coefficients were 0.82(p$lt;0.001), 0.46(p=0.038), and 0.44(p=0.048) respectively. Conclusion: Precision error of BIA(Inbody 2.0) method was 3.4%. The correlation of between densitometry and BIA was statistically more significant than that of between densitometry and BMI, and Brocas method. When we diagnose obesity, considering percent body fat which measured by BIA method as well as anthropometric indices is more reasonable than that of anthropometric indices alone.

The purpose of this study is to assess the adherence to dietary intervention for prevention of coronary heart disease (CHD) in postmenopausal women by observing changes of antioxidant vitamins and fatty acid composition in dietary intake and seam level. The subjects with hypercholesterolemia (TC≥240mg/dl) were treated with one of hormone replacement therapy (HRT group), dietary intervention (DIET group) or combination of hormone replacement therapy and dietary intervention (HRT+DIET group) for 12 weeks. The results were as followed. Mean daily nutrient intakes were not significantly changed in the HRT group, but were significantly changed in the DIET group and the HRT+DIET group. Especially, dietary vitamin A and E intakes were increased from less than 75% to more than 90% of RDA for Korean in the two groups. With changes of dietary intakes, serum vitamin A and E levels were also significantly increased in the DIET group and tended to increase in the HRT+DIET group. Dietary fatty acid composition was also not significantly changed in the HRT group, but was significantly chanced in the DIET group and the HRT+DIET group. With changes of dietary fatty acid composition, serum phospholipid fatty acid composition was significantly changed in the DIET group and the HRT+DIET group although there was tendency of returning to initial value after 12 weeks. Judging from changes in serum phospholipid fatty acid composition, subjects' adherence to dietary intervention tended to decrease after 12 weeks. However, the changes of antioxidant vitamins and fatty acid composition in dietary intake were compatible with the changes of those in serum level, and we can conclude that dietary intervention was adhered quite well by subjects.
