Relationships among the Nutritional Risk Index for Japanese Hemodialysis Patients, Geriatric Nutritional Risk Index, Motor Function and Skeletal Muscle Mass Index in Outpatient Maintenance Hemodialysis Patients: A Retrospective Observational Study

Abstract

[Purpose] To investigate the relationships among the Nutritional Risk Index for Japanese Hemodialysis Patients (NRI-JH), Geriatric Nutritional Risk Index (GNRI), motor function and Skeletal Muscle Mass Index (SMI), and to examine the usefulness of NRI-JH. [Participants and Methods] Sixty outpatients (38 males and 22 females) on maintenance hemodialysis were included in the study. Basic characteristics such as age, gender, height, dry weight, Body Mass Index, NRI-JH score, GNRI, hand-grip strength (HGS), five times sit-to-stand test, and SMI were used as assessment items. [Results] The NRI-JH score was not significantly related to any of the items, and the GNRI was positively related to SMI and HGS. [Conclusion] The NRI-JH score was not related to GNRI or motor function. A limitation of this study was the limited number of subjects. Future studies are needed to examine the associations of the NRI-JH with nutritional screening, exercise function, and SMI.
