    Abstract:
    BACKGROUND: The SARC-F questionnaire has been developed as a rapid diagnostic test that can be used to screen for sarcopenia. AIM: To investigate the reliability and validity of the Vietnamese version of SARC-F as a screening tool for sarcopenia in older patients in Vietnam. METHODS: A cross-sectional study was conducted in older people attending the outpatient clinics of the National Geriatric Hospital in Vietnam. Muscle mass (using dual-energy X-ray absorptiometry), handgrip strength and gait speed were assessed. SARC-F was validated against the three standard criteria for sarcopenia: the Foundation for the National Institutes of Health (FNIH), Asia Working Group for Sarcopenia (AWGS 2019) and European Working Group on Sarcopenia in Older People (EWGSOP2). RESULTS: There were 764 participants (mean age 71.5 ± 8.9 years). The Vietnamese SARC-F questionnaire had a good internal consistency (Cronbach's alpha 0.85). The prevalence of sarcopenia was 49.2% according to SARC-F and 48.3%, 61.1% and 52.6% according to FNIH, AWGS 2019 and EWGSOP2, respectively. The sensitivity and specificity of SARC-F in identifying sarcopenia were 67.1% and 66.7% (for FINH), 66.7% and 67.1% (for AWGS 2019), and 64.9% and 68.2% (for EWGSOP2). The AUCs of SARC-F were 0.71-0.72 against the three sarcopenia criteria. CONCLUSION: The Vietnamese version of SARC-F questionnaire has acceptable diagnostic value for sarcopenia. SARC-F could be used as an initial screening for sarcopenia in hospital clinics.
