Association between bone mineral density, muscle volume, walking ability, and geriatric nutritional risk index in hemodialysis patients.
BACKGROUND AND OBJECTIVES: Hemodialysis patients are at risk for bone loss and sarcopenia, characterized by reduced muscle mass and limited mobility/function. Osteoporosis and sarcopenia both increase the risk of hospitalization and death in affected individuals. Malnutrition also occurs as a complication of hemodialysis and has been identified as a risk factor for osteoporosis and sarcopenia. In this study, we examined the relationship between osteoporosis, muscle volume, walking ability, and malnutrition in hemodialysis patients.
METHODS AND STUDY DESIGN: Forty-five hemodialysis patients were evaluated. Bone mineral density (BMD) and muscle volume were measured by dual-energy X-ray absorptiometry. Muscle volume and strength were evaluated using lean mass index (LMI), handgrip strength, and walking ability. The time required for a patient to walk 10 meters was measured to evaluate walking ability. The geriatric nutritional risk index (GNRI) was used to assess malnutrition.
RESULTS: Multiple linear regression analysis showed that older age, female sex, lower LMI, and higher total type I procollagen N-terminal propeptide were correlated with lower BMD of lumbar spine. Higher age and lower LMI were correlated with lower BMD of the femoral neck. Female sex and lower GNRI were correlated with lower LMI. Longer duration of hemodialysis was correlated with lower walking ability.
CONCLUSIONS: Our findings suggest that muscle preservation is required to maintain both lumbar spine and femoral neck BMD. Similarly, nutritional management is necessary to maintain BMD via preservation of muscle volume. Complementary nutritional therapies are needed to improve osteoporosis and sarcopenia in high-risk hemodialysis patients.
