Abstract

Aim: Oxidative stress (OS) plays a major role in pathogenic mechanisms associated with metabolic syndrome (Mets) yet the main component of Mets contributing most to OS is not well elucidated. Hence, the aim of this study was to investigate the oxidative-antioxidative status in Mets subjects and to determine the main predicting component of OS. Methods: Anthropometric measures, fasting blood glucose, lipid profile, antioxidant enzymes [catalase, superoxide dismutase (SOD) and glutathione peroxidase (GPx)], reduced glutathione (GSH), malondialdehyde (MDA) and protein carbonyl were assessed in 172 adult UAE residents. International Diabetes Federation criteria were used for Mets diagnosis. Mets Scores (0–5) were calculated and assigned per subject based on number of components. Results: Of all participants, 22.1% had Mets and 49.4% had large waist circumference (WC). Significant lower levels of catalase, SOD, GPx and GSH, and higher levels of MDA and protein carbonyl were observed in subjects with Mets. In addition, catalase, SOD, GPx, and GSH correlated negatively, while MDA and protein carbonyl correlated positively with almost all Mets components. Similar trend of correlations was noticed with Mets Scores. When adjusted for age and gender, linear regression analysis revealed that subjects with large WC demonstrated significantly lower levels of antioxidative enzymes and GSH, and higher levels of MDA and protein carbonyl. Consequently, WC emerged as the best predictor of OS. Conclusions: The degree of OS is dependent on the Mets Scores, and WC contributes independently to increased OS among adults in UAE.
