Relationship between metabolic syndrome components and oxidative stress in elderly community-dwelling Mexicans.

Aim: To determine the relationship between metabolic syndrome (MetS) components and oxidative stress (OxS) in elderly community-dwelling Mexicans.

Methods: We carried out a comparative cross-sectional study on 113 elderly subjects (> or =60 years old); 50 of them did not have MetS and 63 did have MetS (based on Adult Treatment Panel III criteria). We measured total antioxidant status (TAS), plasma lipid peroxidation (LPO), antioxidant activity of superoxide dismutase (SOD) and glutathione peroxidase (GPx), and calculated the SOD/GPx ratio.
