Nutritional status of the very old: anthropometric and biochemical findings in apparently healthy women in old people's homes.
To obtain reference values for comparison with malnourished geriatric patients, the nutritional status of 50 apparently healthy women aged 75 or older living independently in two old people's homes in Heidelberg was examined. All women were able to walk, and were free from overt disease and signs of mental deterioration. Anthropometric measurements (body height and weight, triceps skinfold thickness, midarm circumference) and biochemical determinations of protein and vitamin status were performed. Anthropometric parameters were similar to those obtained in "younger" samples of healthy elderly, lower than those reported in younger adults, and markedly greater than those reported in geriatric patients. The majority of biochemical findings were within normal reference ranges established for healthy young adults. Only plasma retinol concentrations were below the reference limit in 8 women (16%). These findings show clearly that even in the very old, major alterations in biochemical indicators of nutritional status are rare. Neither advanced age nor institutionalization are associated with malnutrition. This obviously suggests that malnutrition in old age is mainly related to physical and mental disabilities.
