Objective. evaluation of the effectiveness of sarc-f sarcopenia screening method in hemodialysis patients. material and methods. 317 patients who received treatment with program bicarbonate hemodialysis for 8.2±5.i years were examined; there were 171 women and 146 men, the mean age was 57.1 + 11.3 years. assessment of the presence of sarcopenia was performed using the method recommended by ewgsop (European working group on sarcopenia in older people). the sarc-f method was used for sarcopenia screening. results. when diagnosing sarcopenia according to the ewgsop recommendations, the sarc-f method showed an accuracy index for the diagnosis of sarcopenia at the level of 53%, i.e. the probability of error was almost equal to the probability of setting the correct diagnosis. for the sarc-f screening method, the area under the roc curve (AUC) did not exceed o.57, which indicates the low predictive value of this method as a method for sarcopenia screening. if there is a risk of developing sarcopenia according to the sarc-f method, there is a significant decrease in the main laboratory parameters, anthropometric parameters, and body composition indicators compared with indicators of patients with a negative result of sarcopenia screening. Conclusion. The use of the sarc-f sarcopenia screening method in hemodialysis patients is inappropriate due to its low predictive value.
