Association of the bioimpedance phase angle and quality of life in postmenopausal osteoporosis

Objectives: Osteoporosis patients with fragility fractures and vertebral deformities have impaired quality of life (QOL). The phase angle is an index calculated from bioelectrical impedance analysis (BIA) measurements that has been reported to be related to clinical outcomes, mortality, and QOL in various diseases. The aim was to investigate the relationship between the phase angle and QOL in patients with postmenopausal osteoporosis. Methods: A total of 81 female patients treated for postmenopausal osteoporosis from September 2019 to March 2020 underwent measurement of bone mineral density (BMD) by dual-energy X-ray absorptiometry, body composition by BIA, and QOL by the 36-Item Short-Form Health Survey (SF-36). Results: The phase angle showed significant positive correlations with the physical functioning (PF) (r = 0.270, p = 0.015) and physical component summary (PCS) (r = 0.251, p = 0.024) of SF-36. The phase angle showed significant positive correlations with appendicular skeletal muscle index (ASMI) (r = 0.456, p
