The objective of the present study was to clarify the influence of nutritional status on serum minerals for long term hospitalized patients. The subjects were 65 long term hospitalized chronic stage rehabilitation patients (37 males and 28 females with an average age of 72.2±13.5) who were examined in terms of the relationship between serum minerals (iron, copper, zinc, calcium, magnesium, phosphorus) and nutritional index (serum albumin, hemoglobin, C-reactive protein). The subjects were divided into two groups by nutritional status. The first group consisted of 30 malnutrition patients (17 males and 13 females with an average age of 74.4±12.8) who were regarded as the malnutrition group, and the other group consisted of 35 non-malnutrition patients (20 males and 15 females with an average age of 70.4±13.8) who were regarded as the non-malnutrition group. For both groups the serum minerals, nutritional index and nutritional intake were compared. The serum albumin showed significantly positive correlations with the serum iron, zinc, calcium, magnesium and phosphorus. The hemoglobin showed significantly positive correlations with the serum iron and zinc. The C-reactive protein showed significantly positive correlations with the serum copper, and showed significantly negative correlations with the serum iron and zinc. There weren't significant correlations between serum mineral and mineral intake. The serum albumin and hemoglobin levels were significantly lower in the malnutrition group than the non-malnutrition group. The C-reactive protein level was significantly lower in the non-malnutrition group than the malnutrition group. The serum iron, zinc and calcium levels were significantly lower in the malnutrition group than the non-malnutrition group. The energy, protein and phosphorus intakes were significantly lower in the malnutrition group than the non-malnutrition group. These results indicated that the serum iron, serum zinc and serum calcium of chronic stage rehabilitation patients were influenced by hypoalbu minemia and anemia. Therefore, it is suggested that the treatment of mineral deficiency of malnutrition patients should be accompanied with efforts to deal with malnutrition, not only an increase of minerals intake.
