Sarcopenic Index and Related Factors in Patients With Type 2 Diabetes Applying to Tertiary Health Care Services

This study was planned retrospectively. Between September 01, 2023 and March 31, 2024, the records of patients who presented to the Diabetes Outpatient Clinic of Goztepe Prof. Dr. Suleyman Yalcin City Hospital for Internal Medicine and whose routine biochemical tests (including NT-proBNP and cystatin C) were found in the system will be retrospectively reviewed. Both male and female patients with a definite diagnosis of type 2 diabetes were included in the study. Inclusion criteria included: age 40 years or older, age 85 years or younger, no acute infection, no steroid use, no acute changes in creatinine or cystatin C levels, no recent surgery, no limb loss. Demographic data included age, gender, duration of diabetes, medications and concomitant diseases. The Fib 4 score was calculated using the patients' routine biochemical and hematologic results. The sarcopenia index was calculated from the serum creatinine/cystatin C values. A cut-off value of 0.90 is normally used for the diagnosis of sarcopenia in people without diabetes, but there is no cut-off value for patients with diabetes. Therefore, in addition to the correlation, the SI value was divided into 3 groups and the patients in the lowest and highest groups were compared with each other.
