In this study, blood serum trace elements, biochemical and hematological parameters were obtained to assess the health status
of an elderly population residing in São Paulo city, SP, Brazil. Results obtained showed that more than 93% of the studied
individuals presented most of the serum trace element concentrations and of the hematological and biochemical data within
the reference values used in clinical laboratories. However, the percentage of elderly presenting recommended low density
lipoprotein (LDL) cholesterol concentrations was low (70%). The study indicated positive correlation between the concentrations
of Zn and LDL-cholesterol (p < 0.06).
