The zinc content of hair and serum was measured in 135 elderly blacks, 60-87 years old, from urban low-income households, in order to assess zinc nutriture in this population. Mean hair zinc concentration was 142 micrograms/g and mean serum concentration was 93 micrograms/dl. However 39% of subjects had much lower concentrations and 11% had very depressed concentrations. These data suggest that low zinc levels in the elderly may be a normal physiological consequence of aging or may represent inadequate zinc intake.
