Abstract

The aim of this study was to measure and compare nutrient intake, anthropometric measurements and serum indices
by percent body fat as one of the index of obesity degree in female college students. Additionally we attempted to
investigate percentile distribution of fat free mass index (FFMI) and fat mass index (FMI) for developing reference
values for these two parameters. The subjects were 91 female college students who were classified to 4 groups
according to the percentile of percent body fat (Group1: 25 th < percentile of percent body fat, Group 2: 25 th ≤
percentile of percent body fat < 50 th, Group 3: 50 th ≤ percentile of percent body fat < 75 th, Group 4: percentile of
percent body fat ≥ 75 th). The mean percent body fat and body mass index were 28.2%, 20.5 kg/m2 respectively. The
mean energy intake was 1707 kcal(81% of KDRIs) and vitamin C, folate, Ca and Zn intake were 73.9%, 54.7%,
79.6%, 97.5% of KDRIs respectively. Most nutrient intake (energy, carbohydrate, cholesterol, fatty acid, Ca, Fe) of
G4 was lower than that of G1, G2 and G3. Serum HDL-cholesterol concentration was significantly lower in G4 than
G1, G2, G3 and it tended to increase as percent body fat decreased. LDL/HDL, AI of G4 were significantly the
highest among the 4 groups and increased as percent body fat increased. The mean fat free mass index and fat mass
index were 14.5 kg/m2, 6.0 kg/m2 respectively. The criteria of sarcopenic obesity which has been defined as under
25 th percentile of FFMI and below 75 th percentile of FMI were shown 12.8 kg/m2, 8.2 kg/m2 respectively in this
study. In conclusion, we should continue to more systematically research on the studies of new obesity measurement
which includes FFMI and FMI as one of the variables. And the public education for weight control that emphasizes
both the understanding of body composition and the importance of nutrition balance is also required. (Korean J
