The aim of this study was to investigate the association between dietary protein intake and change of muscle strength and skeletal muscle mass in elderly nondialysis CKD patients, eventually to propose optimal protein intake in elderly CKD patients.
Efficacy
Confirmatory
Pragmatic
Not applicable
To clarify the association between dietary protein intake and percent change in baseline muscle strength and skeletal muscle mass over two years, in elderly CKD patients.
To clarify the association between dietary protein intake and factors affecting muscle mass and muscle strength (serum amino acid concentration, acid-base balance, serum vitamin D concentration)

Measurement item
Protein intake is calculated by urine storage.
The Amount of energy intake, animal protein and vegetable protein are estimated by the food frequency questionnaire.
Muscle strength is measured by the following items
Grip strength
Isometric knee extension force with a hand-held dynamometer
Skeletal muscle mass is measured by the bioelectrical impedance analysis, and skeletal muscle index (SMI)is calculated.
