Anthropometry, computed tomography(CT) at the nmbilical levels, nutrient intake, blood pressure, serum levels of lipids and lipoproteins and response of glucose, c-peptide, insulin, and free fatty acid(FFA) during oral glucose tolerance
test(OGTT)
were
estimated on 11 normal-weight controls and 35 overweight and obese middle-aged men. the areas of total abdominal, subcutaneous and visceral were determined by CT scanning technique. total abdominal fat area correlated the most significantly with
the
levels of serum lipids, lipoproteins and insulin among several obese indices. compared with normal-weight controls, overweight and obese men with abdominal fat lower than 29000㎟ showed an increase in waist-hip ratio, areas of total
abdominal(35%).
visceral and subcutaneous fat and C-peptide response area during OGTT, though age, percent ideal body weight, body mass index, % body fat, and all biochemical indices except C-peptide response area were not different between two groups.
Overweight
and
obese men with abdominal fat greater than 29000㎟ showed a higher values in total abdominal fat(85%), serum levels of triglyceride, total- and LDL-cholesterol, the ratio of LDL- to HDL-cholesterol, and response areas of FFA, insulin and C-peptide
during
OGTT than normal-weight controls. Overweight and obese men with great abdominal fat showed an increase in alcohol ingestion and percent calorie intake per total energy expenditure, compared with normal-weight controls. Our results indicated that
obesity
and a certain level of total abdominal fat accumulation is required to observe abnormal levels of serum lipids, lipoproteins and insulin in Korean middle-aged men. In addition, increased alcohol and calorie intake and decreased physical activity
could
partly explain total abdominal fat accumulation in men.
