Abstract
Background: In postmenopausal women, partly in relation to advancing age and partly due to estrogen deficiency, there is increased risk of coronary heart disease (CHD). The oxidation of Low density lipoprotein (LDL) is centrally involved in the initiation of atherosclerosis which ultimately results in CHD. Paraoxonase 1 (PON1) is a major antiatherosclerotic component of High density lipoprotein (HDL) which retards the oxidation of LDL. This study aimed to evaluate the relation between Paraoxonase1 (PON1) activity and post-menopausal status
Methods: On the basis of consecutive recruitment, 80 women between 20 and 76 years old participated in the study. Anthropometric indices (waist circumference, Body mass index) and biochemical parameters (fasting blood glucose, Total cholesterol, Triglyceride, HDL cholesterol and PON1) were measured.
Results: Post-menopausal women in comparison to pre-menopausal women, have significantly low HDL cholesterol and PON1 activity and significantly increased Triglyceride and VLDL cholesterol. PON1 activity was negatively correlated with age, TC, TG, LDL-C. (r = -0.574, -0.119, -0.226, -0.473 respectively) and positively correlated with HDL-C (r = 0.368). Stepwise multiple regression analysis demonstrated HDL-C and menopausal status as the best determinant for PON1 (R2 5 0.320, p < 0.05)
Conclusion: The use of PON1 measurement may facilitate a simple parameter to evaluate the risk of CHD and to work on its secondary prevention.
