Özet
Objective: The objective of this study was to evaluate the reliability and validity of the Turkish version of the study of osteoporotic fractures (SOF) index, and to investigate the prognostic power of the SOF index in predicting the risk for sarcopenia in the geriatric population. Materials and Methods: The sample of this cross-sectional study consisted of 144 geriatric patients who applied to the outpatient clinic where this study was conducted between July 2017 to July 2018. The frailty status of patients was evaluated using the SOF index. The European Working Group on Sarcopenia in Older People diagnostic criteria were used in the diagnosis of sarcopenia. Accordingly, patients were divided into two groups as the sarcopenia and non-sarcopenia groups. Patients' measurement results were recorded and comparatively analyzed between the groups. Results: The rate of sarcopenia was significantly higher in patients who were determined to be frail based on SOF index than the remaining patients (93.2% vs. 61.5%, respectively; p<0.001). The kappa value was determined as 0.608 based on the qualitative data, in substantial agreement with Cohen's Kappa coefficient, indicating reliability. The ROC analysis revealed that the sensitivity and specificity of SOF index cut-off value of 1 in determining sarcopenia were 76.4% and 55.6%, respectively. The validity of the SOF index with a cut-off value of 1 was found as 0.659 (validity values of >0.5 indicate statistical significance). Conclusion: The study findings indicate that the SOF index is a feasible, valid and reliable tool, and it has a high positive prognostic value in predicting sarcopenia.
