Background: Middle-aged Korean women over 30 years old reportedly become fat in particular after delivery. The obesity ratio has steadily increased due to economic growth coupled with change in diet pattern, causing appearance and health problems against middle-aged women. Since abdominal obesity particularly relates to metabolic disease including heartblood vessel disorder, the purpose of this study is to analyze the serum component and the nutritional aspects of middle-aged women with abdominal obesity, who are 30 to 55 years old, in order to find the physiological causes and problems of middle-aged abdominal obese women in Korea.
Methods: Sixty six women aged between 30 and 55 who have BMI above 25 kg/㎡ and live in Seoul, Korea and whose WHR is 0.85 or more are selected as an subject of this study.
Results: 1) As for the diet pattern, 51.72% of pre-obese group and 70% of obese group do not have breakfast, showing significant difference between two groups. The average daily caloric intake is 1823.91 kcal and 1740.97 kcal for pre-obese group and obese group, respectively which are 91.20% and 87.05% of RDA. It is lower in obese group than in pre-obese group, but is not statistically significant. Both groups intake more protein, phosphorus, vitamin A, vitamin B1, niacin and vitamin C than RDA, but intake less calcium, iron, vitamin B₂, than RDA, corresponding to 66.28%, 67.38% and 84.23% of RDA, respectively. Obese group and pre-obese group exceed RDA of 300mg. 2) The cholesterol and LDL-cholesterol level are higher in both groups than normal. The free fatty acid and ALT concentration is higher in obese group than pre-obese group, showing significant difference between two groups. This means that the free fatty acid and ALT concentration concentration substantially depends on obesity level. There is no significant difference in total antioxidant, AST, but ALT between two groups. The total antioxidant is low and in a normal range in both groups. 3) The free fatty acid, ALT and AST concentration are related with weight, BMI, body fat, abdominal circumference, waist circumference, significantly.
Conclusion: Comparing pre-obese group with obese group, abdominal obesity of women is related with regularity and with diet pattern such as "skipping breakfast" more closely than caloric intake is. The free fatty acid and ALT concentration substantially depends on obesity level in abdominal obese women and the free fatty acid, ALT and AST concentration is related with abdominal obesity.
