Stable isotope ratios of nitrogen (δ15N) and carbon (δ13C) in scalp hair of elderly patients who received enteral nutrition for long periods were analyzed to assess nutritional status: the δ15N and δ13C in the hair of patients who received enteral nutrition were compared with those of healthy persons, respectively. The average values of the δ15N and δ13C in the hair of patients who received enteral nutrition (n = 19) were higher and lower than those of healthy persons (n = 17), respectively. A negative correlation was observed between the δ15N in the hair of patients and the dose of energy (r = -0.490, P < 0.05), whereas positive correlation was found between the δ13C and the dose of energy (r = 0.563, P < 0.05). The δ15N and δ13C in scalp hair may be good indicators for assessing the nutritional status of the elderly patients who received enteral nutrition for long period.
