Zinc nutrition of preschool children in the Denver Head Start program.
Low income diets provide relatively little zinc. This study was designed to evaluate the zinc nutritional states of 74 low income preschool children enrolled in the Denver Head Start Program. Zinc is necessary for normal growth, hence children were selected on the bases of low height percentiles. The mean (+/- SE) hair zinc concentration was 87.0 +/- 5.9 mug/g, and the mean plasma zinc concentration was 74.5 +/- 1.5 mug/100 ml. These levels were both lower (P is less than 0.005) than those of middle income children of similar age. Sixty-eight percent of the study group had a hair zinc concentration less than 70 mug/g and/or a plasma zinc concentration less than 68 mug/100 ml. These results indicate that inadequate zinc nutrition may be common among preschool children with low growth percentiles from low income families.
