Food intake of institutionalized women over 80 years of age.

Food intake of 30 women over 80 years of age and residing in a long-term care facility was determined for a five-day period using the weighed intake method. Purposes of the study were to examine the contribution to nutrient intake of foods from eight major food groups; to characterize intake by time of day; and to examine the effect of age on nutrient intake. The results indicated that intakes of calcium, thiamin, vitamin A, zinc, and protein were below recommended levels. Analysis of intake by food group revealed that the grain group was the primary source of energy and many nutrients. Percentage consumption of foods in this group was significantly higher than that of vegetables or meat and alternates. Analysis of intake by time of day indicated that more energy was consumed at breakfast than at dinner. Advanced age was negatively correlated with overall dietary adequacy, although the distribution of energy intake from the eight food groups did not change with age. Implications of the results, for these subjects and similar groups of elderly, are discussed.
