- Abstract
Objectives To investigate the associations of serum superoxide dismutase ( SOD) , malondialdehyde (MDA), and uric acid (UA) with blood pressure and the prevalence of hypertension in a Chinese population. Methods We measured serum superoxide dismutase (SOD),malondialdehyde (MDA) and uric acid (UA) in 506 randomly selected participants. For database management and statistical analysis, we used the SAS 9.13 Software. Results Compared with normotensive participants,hypertensive patients had significantly lower serum levels of superoxide dismutase activity ( =0.0002), and higher serum levels of malondialdehyde and uric acid ( <0.05) .Univariate analysis indicated that serum superoxide dismutase activity was negatively associated with blood pressure, and serum levels of uric acid (P 0.0001) ; while serum levels of malondialdehyde was positively associated with blood pressure, and serum levels of uric acid (P 0.05) . There was significant difference in systolic (Ptrend=0.02) and diastolic blood pressure (Ptrend=0.04) between three groups defined by tertiles of serum levels of superoxide dismutase, with a lower blood pressure in the highest tertile than in the lowest tertile. Furthermore, the systolic (Ptrend=0.01) and diastolic blood pressure (Ptrend=0.003) in the highest tertile, which defied by the serum levels of malondialdehyde, were significantly higher than those in the lowest tertile. Conclusions Hypertensive patients have a disturbed oxidative and anti-oxidative balance. Oxidative stress may play a role in the pathogenesis of hypertension in Chinese.
