Prevalence and Associated Factors of Sarcopenia Among Elderly Patients in Osteoporosis Clinic

Kowloon Hospital, Hong Kong94 enrolled

Overview

This was a cross-sectional study. Patients who attended the osteoporosis clinic of Kowloon Hospital from June to December 2022 were recruited. Grip strength and appendicular skeletal muscle mass index were measured with a Jamar dynamometer and a bioimpedance analyser. Since most patients in our clinic are of Chinese ethnicity, the diagnostic criteria in the Consensus Update on Sarcopenia Diagnosis and Treatment by the Asian Working Group for Sarcopenia in 2019 was utilised. The diagnosis of sarcopenia was established by the presence of both low grip strength (Male: \< 28 kg, Female \< 18 kg) and low appendicular skeletal mass (Male: \< 7.0 kg/m2, Female: \< 5.7 kg/m2)
