Objective: Recent study showed high chemokine CXC ligand 5 (CXCL5) is thought to be associated with insulin resistance in humans. However, evidence from large-scale populations about the relationship between serum CXCL5 level and metabolic phenotypes is scarce. Here we sought to evaluate serum CXCL5 distribution and its association with metabolic phenotypes among middle-aged and older Chinese. Research Design and Methods: We evaluated serum CXCL5 in a cross-sectional sample of 3225 Chinese aged from 50 to 88 yr in a Shanghai downtown district by ELISA. Glucose, insulin, lipid profile, inflammatory marker, and adipokine were also measured. Results: The crude mean of serum CXCL5 concentrations were 1493.31 pg/ml for men and 2059.42 pg/ml for women (P 0.05). Conclusions: Elevated circulating CXCL5 concentrations were associated with higher risk of hypercholesterolemia in middle-aged and elderly Chinese independent of obesity, inflammation, adipokines, and other risk factors but not insulin resistance.
