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

Completed

• Conditions: Sarcopenia; Osteoporosis

• Registration Number: NCT05688150
• Lead Sponsor: Kowloon Hospital, Hong Kong

Brief Summary

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)

Primary Outcome Measures

Name	Time	Method
Prevalence of Sarcopenia	June - December 2022	The diagnosis of sarcopenia would be established by the co-existence of low grip strength and low appendicular skeletal muscle mass.
Grip strength	June - December 2022	Grip strength would be measured with Jamar digital dynamometer.
Appendicular Skeletal Muscle Mass Index	June - December 2022	Appendicular Skeletal Muscle Mass Index would be measured with bioimpedance analyzer.

Secondary Outcome Measures

Name	Time	Method
Association between BMI and Sarcopenia.	June - December 2022	BMI would be measured on clinic attendance.
Association between Frailty and Sarcopenia.	June - December 2022	Clinical Frailty Scale would be documented in clinical consultation.
Association between Bone Mineral Densities and Sarcopenia	June - December 2022	Bone mineral densities of spine and neck of femur would be extracted from the report of dual-energy X-ray absorptiometry.
Association between Charlson Comorbidities Index and Sarcopenia	June - December 2022	Components of Charlson Comorbidities Index would be extracted from medical record.
