Abstract
OBJECTIVES: To compare the diagnostic value of the 5-component questionnaire that measures strength, assistance walking, rise from a chair, climb stairs, and falls (SARC-F) and SARC-F combined with calf circumference (SARC-CalF) for screening sarcopenia in community-dwelling older adults. DESIGN: A diagnostic accuracy study. SETTING: A community in Chengdu, China. PARTICIPANTS: Older adults aged 60 years or older. MEASUREMENTS: Muscle mass, muscle strength, and physical performance were estimated using a bioimpedance analysis device, handgrip strength, and gait speed, respectively. Four commonly used diagnostic criteria [European Working Group on Sarcopenia in Older People (EWGSOP), Asian Working Group for Sarcopenia (AWGS), International Working Group on Sarcopenia (IWGS), and Foundation for the National Institutes of Health (FNIH) criteria] were applied as the reference standard, separately. The sensitivity/specificity analyses of the SARC-F and SARC-CalF methods were evaluated. The receiver operating characteristics curves and the area under the receiver operating characteristics curves were used to compare the overall diagnostic accuracy of the SARC-F and SARC-CalF for identifying sarcopenia. RESULTS: We included 160 men and 224 women. Based on the 4 diagnostic criteria, the prevalence of sarcopenia ranged from 11.7% to 25.0%. Using the AWGS criteria as the reference standard, the SARC-CalF had a sensitivity of 60.7% and a specificity of 94.7% in the whole study population, whereas the SARC-F had a sensitivity of 29.5% and a specificity of 98.1%. The area under the receiver operating characteristics curves for SARC-CalF and SARC-F were 0.92 (95% confidence interval 0.89‒0.94) and 0.89 (95% confidence interval 0.86‒0.92), respectively (P = .003). We obtained similar results when using the other 3 criteria as the reference standard. Subgroup analyses revealed similar results in both men and women. CONCLUSIONS: SARC-CalF significantly improves the sensitivity and overall diagnostic accuracy of SARC-F for screening sarcopenia in community-dwelling older adults.
