BACKGROUD/OBEJECTIVES: It is hypothesized that obese people with dyslipidemia is more likely to have increased oxidativestress and decreased antioxidant status, in comparison with the controls who were obese without dyslipidemia. Thus, theaims of the present study were to determine the dietary intakes, plasma adipokines, and antioxidative systems between obesewith dyslipidemia and obese without dyslipidemia were investigated. SUBJECTS/METHODS: Female subjects who were between 20 and 55 years old, and whose BMI was 23 or greater were recruited. Subjects who met the criteria of BMI ≥ 23, total cholesterol ≥ 200 mg/dL, LDL cholesterol ≥ 130 mg/dL, and TG ≥ 110mg/dL were categorized Obese with dyslipidemia. Anthropometric measurements and blood biochemical tests were conducted. The diet survey was conducted by a trained dietitian using two days of 24 hour dietary recall. The lipid peroxidation, theplasma total antioxidant capacity (TAC), the activities of antioxidantive enzymes, and various antioxidantive vitamins levelswere determined. RESULTS: Plasma adiponectin and leptin levels were also determined. There were no significant differences for age, Body Massindex (BMI), and body fat (%), waist-size between two groups. Obese with dyslipidemia had significantly high levels of totalcholesterol, triglyceride, LDL-cholesterol, the ratio of total cholesterol/HDL-C, and the ratio of HDL-C /LDL-C, respectively. Bloodalkaline phosphatase level was statistically different between the two groups (P < 0.05). No statistical significance in dietaryintake between two groups was shown. In case of obese with dyslipidemia group, the levels of GSH-Px (P < 0.05) and catalase(P < 0.05) as well as adjusted blood retinol (P < 0.05) and tocopherol level (P < 0.05) were significantly low. However, the plasmaconcentration of leptin was significantly high (P < 0.05). CONCLUSIONS: Obesity with dyslipidemia was shown to have high arthtrogenic index, depleted antioxidant status, and higherblood leptin levels which suggest higher risks of oxidative stress and cardiovascular diseases.
