Comparison of diagnostic value of the SARC-F and its two modified versions (SARCF-EBM and SARCF-calF) in older adults in Turkey.

OBJECTIVES

This study aimed to assess the diagnostic value of the SARC-F and its two modified versions, SARC-F EBM and SARCCalF.

MATERIAL AND

METHODS

This prospective observational study included 468 participants aged ≥ 65 years. The diagnostic tools assessed were the SARC-F, SARC-F EBM, and SARCCalF. Data on muscle strength, mass, and function were collected.

RESULTS

For BMI-based sarcopenia, SARC-F EBM demonstrated the highest sensitivity (40.0%, 95% CI: 31-49.5) and specificity (80.7%, 95% CI: 76.4-84.6), with an AUC of 0.674 (95% CI: 0.617-0.732, p < 0.001). SARCCalF had a lower sensitivity (17.1%, 95% CI: 10.8-25.1) but a higher specificity (87.1%, 95% CI: 83.3-90.2) and an AUC of 0.574 (95% CI: 0.512-0.636, p < 0.001).

CONCLUSION

The SARC-F EBM demonstrated superior sensitivity and diagnostic accuracy compared to the original SARC-F and SARCCalF for detecting sarcopenia in older adults. SARC-F EBM may be preferred in clinical settings due to its higher sensitivity.
