The interconnection between aging and metabolic syndrome (MetS) and their effect on oxidative stress (OxS) status lacks adequate information. Additionally, the agerelated changes of antioxidant defenses and OxS in senior women with MetS in comparison to healthy senior women are not yet established. We analyzed the correlation between oxidative defense status and OxS with MetS components. Through further examination of MetS and aging, we aimed to determine their independent effects on OxS and oxidative defense status. This community-based cross-sectional study was conducted in the rural area of Babol, Iran. A total of 75 women of ≥60 years of age with MetS along with 89 women with similar conditions without the MetS, serving as the control group, were studied. Blood glucose, lipid profile, malondialdehyde (MDA) and total antioxidant capacity (TAC) were determined. Data were analyzed using multiple linear regression, ANOVA and independent t-tests. MDA and TAC levels independently showed a significant correlation with triglyceride (TG), waist circumference, fasting blood glucose and high-density lipoprotein cholesterol (HDL-C). As suggested by the standardized B (0.810, -0.783, P<0.001; -0.052, P<0.001, 0.047, P<0.01), TG followed by HDL-C were the most strongly correlated factors with MDA and TAC. Furthermore, MetS and age were independent risk factors for antioxidant activity reduction and OxS. However, MetS had a much higher predictive power than age (standardized B 0.573 for MetS and 0.376 for age, P<0.001). Aging and MetS, both lead to OxS, but the impact of MetS on this disorder was far greater than the effect of age. However, their cumulative effects can lead to a worsening of the situation. Therefore, early diagnosis and treatment of MetS, especially in the elderly can prevent any adverse impact of MetS. [ABSTRACT FROM AUTHOR]
