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.
