ORIGINAL RESEARCH COMMUNICATIONS

Nutritional status of a population sample in Macon County, Alabama

J Prothro, M Mickles and B Tolbert

A nutrition survey was conducted in Macon County, Alabama, with a population sample of 102 individuals, 76% of whom were black. Three 24- hr dietary recalls were obtained for each participant and 24 nutrients and energy were calculated for each combined 3-day intake. Serological and hematological analyses of blood were performed. Dietary calculations indicated that intakes of calcium, vitamin B12, calories, and iron were lowest within the population sample. Blood analyses did not confirm the calculated inadequacies of dietary calcium, vitamin B12, or iron. Body weight data did not support the calculated inadequate energy intakes. Serum analysis indicated a folic acid deficiency. Mean intakes of energy and macronutrients were higher in nonblacks than in blacks; for most vitamins and minerals, the same was true. The lower calcium intakes among blacks than among nonblacks in the growing years exceeded the differential in energy intakes. Higher serum vitamin B12 levels in blacks than in nonblacks were observed but not explained.
