The zinc status of 135 elderly blacks, aged 60 to 87 years, from urban low-income households was evaluated based on the zinc content of hair and/or serum. The mean (+/- SD) hair zinc concentration was 142 +/- 77 microgram/g and the mean (+/- SD) serum zinc concentration was 93 +/- 15 microgram/dl. Of the study population 39% had a hair zinc concentration less than or equal to 100 microgram/g and/or a serum zinc concentration less than or equal to 80 microgram/dl. Eleven percent had a hair zinc concentration less than or equal to 70 microgram/g and/or a serum zinc concentration less than or equal to 70 microgram/dl. These findings suggest that the zinc status of this elderly population may be less than ideal.
