Comparison of serum Total Antioxidant Capacity between metabolic syndrome patients and non-metabolic syndrome people with normal or high BMI

Regarding the considerable role of oxidative stress in different diseases including metabolic syndrome; various changes in metabolic syndrome patients namely increased visceral fat and blood lipid profile, insulin resistance, and impaired glucose tolerance affected by oxidative stress can subsequently cause changes in serum total antioxidant capacity. This study aimed to determine the differences in plasma total antioxidant capacity between metabolic syndrome patients and those without metabolic syndrome with normal weight, overweight and obesity. A case-control study was carried out among 146 men and women (aged 20-55 years) in Endocrinology Center of Tehran University of Medical Sciences. The case group included overweight/obese subjects with metabolic syndrome and the two control groups were weight-matched subjects without metabolic syndrome and normal weight subjects without metabolic syndrome. Total antioxidant capacity was determined using colorimetric method. Waist circumference and total antioxidant capacity of case group were significantly higher than that of both control groups (p
