Abstract |
Background/Objectives |
The physical phenotype of frailty, described by Fried et al., shows significant overlap with sarcopenia. EWGSOP2 recommends the SARC-F questionnaire to screen for sarcopenia. Considering common features between both conditions, we aimed to investigate whether the SARC-F questionnaire could also be a valid and reliable tool to screen or evaluate frailty.
Design |
Retrospective, cross-sectional.
Setting |
Istanbul University Istanbul Faculty of Medicine.
Participants |
A total of 447 older adults (70.7% female, mean age: 74.5±6.6 years).
Measurements |
Frailty was assessed by the modified Fried scale. SARC-F questionnaire was performed by all participants. We used a receiver operating characteristics curve to obtain SARC-F cut-off values to detect frailty, and calculated the area under the curve and 95% confidence interval.
Results |
There were 93 (20.8%) older adults with frailty according to the modified Fried scale. SARC-F cut-off ≥1 had 91.4% sensitivity and 44.9% specificity. SARC-F cut-off ≥2 presented the best balance between sensitivity and specificity (sensitivity: 74.1% vs. specificity: 73.7%) to identify frailty (area under curve: 0.807; 95% confidence interval: 0.76–0.84, p<0.001). SARC-F ≥4 had high specificity of 92.6% with a sensitivity of 46.2%.
Conclusion |
We suggest that SARC-F ≥1 point can be used to screen for frailty with high sensitivity, and SARC-F ≥4 can be used to diagnose frailty with high specificity. SARC-F may be used to evaluate frailty in usual geriatric practice.
