JOURNAL FREE ACCESSThe Mini Nutritional Assessment (MNA), developed in Europe in 1994, is presently considered to be a standard method for assessing the nutritional status of the elderly in western countries. In Japan, however, the MNA is not yet accepted as a reliable method for assessing the nutritional status of the Japanese super-elderly on the grounds that over 85% of Japanese elderly are simply included in at risk or malnourished groups, and that the MNA alone is not useful for selecting the poorest nourished among them. In this study, we investigated the applicability of the MNA to the Japanese super-elderly (mean age=87 years) by dividing the MNA at risk and malnourished groups into four subgroups using both the MNA scores alone and also in combination with serum albumin level (cut-off point, 3.5g/dL). Our results indicated that the MNA was also applicable to the Japanese super-elderly. When at risk or malnourished subjects were classified into four subgroups according to MNA scores in combination with the serum albumin level, it predicted the final outcome of institutionalized super-elderly and was helpful for selecting those requiring earlier nutritional interventions.View full abstractDownload PDF (1125K) -

JOURNAL FREE ACCESSBoth exercise and chromium (Cr) exert beneficial effects on glucose tolerance. The mechanism by which exercise improves glucose tolerance may involve an alteration of Cr metabolism. To determine the effects of chronic exercise on urinary Cr excretion, we measured the effects of exercise tolerance on urinary Cr concentration in 30 healthy young women (aged 18-22yr). The subjects underwent a bicycle ergometer exercise test for 60min, and urine samples were taken prior to excerise, and less than 3h, 24, and 48h after exercise. Urinary Cr, copper, zinc, and nickel concentrations were measured at trace level by inductively coupled plasma mass spectrometry using a dynamic reaction cell technique. The changes in urinary Cr excretion were quite different among the three chronic exercise groups. In particular, the urinary Cr concentration (mean±SEM) prior to exercise was significantly higher in sedentary subjects than in trained subjects (4.53±1.14 and 1.33±0.17ng/mg urinary creatinine, respectively, p<0.05). These data demonstrate that chronic exercise has no discernible impact on urinary Cr excretion after a single bout of exercise in young women and that hypokinesis leads to increased basal Cr excretion.View full abstractDownload PDF (1017K) -

JOURNAL FREE ACCESSThe purpose of this study was to clarify age-dependent changes in bone mass using quantitative ultrasound (QUS) cross-sectionally in 3468 Japanese children and adolescents of both genders. We also assessed the relationship between bone mass and body composition. We measured transmission index (TI) and speed of sound (SOS) at the calcaneus using an AOS-100 instument (ALOKA Co., Ltd, Tokyo). The osteo sono-assessment index (OSI) was calculated from the TI and SOS. The OSI was considered to reflect bone mass. OSI increased with age in subjects aged 9-14 years and there was no significant difference in OSI between the genders. OSI was significantly higher in male than in female subjects aged over 15 years. In females, those who had experienced menarche had a higher OSI than those who had not. Furthermore, we divided the subjects into four age groups (9-12yr, 13-15yr, 16-18yr, and 19-22yr) for each gender. In females, body weight, BMI, LBM and, percentage body fat had a significant association with OSI in every age group. In males aged 19-22yr, OSI showed no significant association with height, body weight, BMI, LBM or percentage body fat.View full abstractDownload PDF (1049K)
