Abstract The casual relationship between intraabdominal visceral fat accumulation and metabolic disorders was analyzed in 46 obese subjects (15 males, 31 females) having 34.1 +/- 5.5 of body mass index (BMI). The distribution of fat was determined by our CT scanning technique (Int J Obesity 7:437, 1983). The total cross-cut area, subcutaneous fat area, and intra-abdominal fat area was measured at the umbilical level. The fasting plasma glucose level, area under the plasma glucose concentration curve after oral glucose loading (plasma glucose area), fasting serum triglyceride level, and serum total cholesterol level were all significantly higher or otherwise greater in the group with intraabdominal visceral fat to subcutaneous fat ratio (V/S ratio) of not less than 0.4 than in the group with a lower V/S ratio, when either all or sex-matched obese subjects were examined, though BMI or the duration of obesity was not different between the two groups. The V/S ratio was significantly correlated with the level of plasma glucose area (r = 0.45, P less than .001) under the curve of 75 g oral glucose tolerance test and also with the serum triglyceride (r = 0.65, P less than .001) and total cholesterol levels (r = 0.61, P less than .001). These relationships were also observed when examined in each sex separately and found to be significant after adjustment for BMI and age by multiple regression analyses.(ABSTRACT TRUNCATED AT 250 WORDS)
