title: Nutritional status of a population assessed on the basis of a group of blood donors.
abstract: Several blood constituents were used to evaluate the nutritional status of a random, consecutive group of 655 blood donors. The population included 503 men and 152 women, with a mean age of 35.1 years; 26.8% of the women and 26.5% of the men had deficient levels of ascorbic acid; 18.0% of the women an 11.9% of the men had hemoglobin levels below normal. Plasma iron was inadequate in 29.3% of the women and 18.6% of the men. A very small number of donors were found to be deficient in carotene, retinol, thiamine, riboflavin and pyridoxine. These findings call attention to an unexpected aspect of nutrition in an apparently healthy, not undernourished population.
