title: Relation of serum zinc and copper to lipids and lipoproteins: the Yi People Study.
abstract: The relations of serum zinc (Zn) and copper (Cu) to serum total cholesterol (TC), low-density-lipoprotein and high-density-lipoprotein cholesterol (LDL-C and HDL-C) and triglycerides were investigated in a population-based sample of 399 men in Southern China. Serum Cu was inversely related to HDL-C (r = -0.21), while Zn/Cu ratio showed a positive association (r = 0.19). These relationships remained significant after adjusting for age, body mass index (kg/m2), physical activity, tobacco smoking and dietary cholesterol, fat, and fiber. While no significant association was observed between serum Cu and serum TC in univariate analysis, a significant negative association was observed in multivariate analysis, after adjustment for the above mentioned independent variables. No significant association between serum Cu and LDL-C was found. These observations, as well as those reported in other studies reviewed herein, suggest that Cu is implicated in the metabolism of HDL-C, although the mechanism involved is not fully understood. No significant associations were found between serum Zn and the lipid variables.
