Conditions
Interventions
Gold Standard:1. Bone density measurement
We used the corresponding BMD value of QCT (Mindways, QCTpro, USA) as the gold standard, in which QCT is the software approved and registered by the Food and
Bone mass loss: 80-120mg/cm^3
Osteoporosis: < 80 mg/cm^3.
2. Measurement of height, skeletal muscle mass and grip strength
The height data of participants were recorded by direct inquiry. Skeletal muscle mass was measured by bioel
(2) The reduction of muscle strength (grip strength) : male < 26kg, female < 18kg.
