Aim And Objective:
Diabetes mellitus is associated with inflammation and increased oxidative stress. In the current study, we aimed to investigate the relationship between type 2 diabetes mellitus (T2DM) and serum pro-oxidant-antioxidant balance (PAB) in a large populationbased study.
Methods:
In this cross-sectional study, 7888 individuals were recruited as part of the Mashhad Stroke and Heart Atherosclerotic Disorders (MASHAD) cohort study. Participants were divided into three groups based on their serum PAB values (levels < 36.4, 36.4-82.6 and > 82.6 HK). Serum PAB values were measured using a colorimetric method and enzyme-linked immune sorbent assay (ELISA).
Results:
Serum PAB in subjects with and without diabetes was reported 76.85 ± 61.07 HK and 69.51 ± 55.50 HK. In subjects with a serum PAB > 82.6 HK the risk of T2DM was 1.2 fold higher in comparison to subjects with a serum PAB < 36.4 HK (OR: 1.26, 95% CI: 1.09 - 1.47, P-value: 0.002). This association remained significant after adjustment for confounding factors in multivariable analysis (OR: 1.19, 95% CI: 1.02 - 1.38, P-value: 0.027).
Conclusion:
Increased pro-oxidant levels may be a major complication of T2DM in our study subjects and PAB could be an indicator of higher oxidative stress in T2DM patients from northeastern Iran.
