ABSTRACT
<p><b>OBJECTIVE</b>To explore the impact of gender on lipoprotein-associated phospholipase A(2) (Lp-PLA(2)) activity and association with known cardiovascular risk factors.</p><p><b>METHODS</b>Participants in this study were recruited from Beijing sub-cohort from the Chinese Multi-provincial Cohort Study (CMCS) database. A total of 1471 participants with complete laboratory data were included in the study (688 male). Lp-PLA(2) activity was determined by colorimetric assay kit.Lp-PLA(2) activity level and correlation between Lp-PLA(2) activity and known risk factors were compared between men and women.</p><p><b>RESULTS</b>(1) Lp-PLA(2) activity was higher in males than in females [(22.73 ± 8.52) nmol·min(-1)·ml(-1) vs.(20.01 ± 8.06) nmol·min(-1)·ml(-1), P < 0.01].(2) Age, waist circumference, systolic blood pressure, diastolic blood pressure and the prevalence of hypertension were higher in males than in females, while total cholesterol, low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) were higher in females than in males (P < 0.05 or P < 0.01).(3)Pearson correlation showed that Lp-PLA(2) activity was correlated with lipids ( total cholesterol, LDL-C, HDL-C, and triglyceride), blood pressure (systolic blood pressure and diastolic blood pressure), and adiposity associated parameters (waist circumference and body mass index) in males (all P < 0.01) and was correlated with lipid level (total cholesterol, LDL-C, HDL-C, and triglyceride) and age in females( P < 0.05 or P < 0.01). Correlations with variables associated with obesity or blood pressure in females were much weaker than those in males (in females, r = 0.02-0.08; in males, r = 0.10-0.16).(4)After adjustment for age, waist circumference, systolic blood pressure, glucose, LDL-C, HDL-C, triglyceride and high sensitivity C-reactive protein by multiple logistic regression model, Lp-PLA(2) activity was still significantly higher in males than in females (OR = 1.72, 95% confidence interval = 1.34-2.21, P < 0.01).</p><p><b>CONCLUSIONS</b>Lp-PLA(2) activity and association with known cardiovascular risk factors differed in males and females. The gender difference in Lp-PLA(2) activity still presents after adjustment for known cardiovascular risk factors in this cohort.</p>
