Abstract
Objective: To evaluate the relationship between surrogate markers of visceral obesity[hypertriglyceridemic waist (HW) phenotype, visceral adiposity index (VAL), lipid accumulation product (LAP)]and atherosclerosis in hemodialysis patients. Methods: A multi-center cross-sectional study was carried out. A total of 961 maintenance hemodialysis (MHD) patients from 11 hemodialysis centers of Guizhou province between July 2016 and September 2017 were enrolled in the study. Anthropometric measures were performed in all subjects. Laboratory parameters including triglyceride, high-density lipoprotein cholesterol, low-density lipoprotein-cholesterol were extracted from the medical records by researchers. Pearson correlation analysis was used to investigate the correlation between HW phenotype, VAI, LAP and plasma atherosclerotic index (AIP). Multivariate linear regression analysis was used to evaluate factors affecting AIP. Results: Totally, 585 men and 376 women aged 18-90 years, with a mean age of (56.08±15.42) years were recruited in the study. Pearson correlation analysis showed that VAI (men: r=0.82, women: r=0.84), LAP (men: r=0.73, women: r=0.74) and having HW phenotype (men: r=0.62, women: r=0.63) correlated positively with AIP (all P<0.001). Multivariate linear regression analysis showed that VAI (men: β=0.77, women: β=0.82) and LAP (men: β=0.73, women: β=0.73) were independent associated factors of AIP after adjustment of BMI, age, smoking and history of diabetes and hypertension (all P<0.001). Conclusions: Surrogate markers of visceral obesity such as having HW phenotype, VAI, LAP correlated positively with AIP. VAI, LAP has positive impacts on AIP independent of BMI, age, smoking and other traditional atherosclerosis risk factors.
