Evaluation Of Sarcopenia By Adding Anthropometric Measurements To The SARC-F Questionnaire

The population of the research is individuals aged 65 and over who applied to Ege University Medical Faculty Hospital Internal Diseases Department, Geriatrics BD Outpatient Clinic. For statistical power analysis; When α=0.05 and the power of the study are 0.80, the minimum number of samples required for the study was determined as 190. The relevant sample size was calculated with the G-Power 3.0.8 package program.

Data collection tools:

1. General information collection form: Investigator collect data about age, gender, chronic diseases, economic status, etc of participants
2. Measurement of Muscle Mass, Muscle Strength, and Gait Speed Body composition analysis was determined by electrical bioimpedance using the Tanita MC-780 multi-frequency segmental Body Composition Analyzer (Tanita Corporation, Tokyo). The appendicular skeletal muscle mass (ASM) was calculated with the Janssen equation for EWGSOP criteria and Sergi equation for EWGSOP 2 criteria. The appendicular muscle mass index (ASMI) was calculated based on the equation: ASM(kg) /height (m2).

Muscle strength (kg) was assessed with the Takei Grip Strength Dynamometer®. Handgrip strength (HS) measurements were made with the subjects in a sitting position, with the elbow and wrist in full extension, three times with an interval of five seconds on both hands, and the highest value among the measurement results was used for analysis. Gender-specific cut-offs were used to define low muscle strength (30 and 20 kg in males and females) for EWGSOP criteria, and (27 and 16 kg in males and females) for EWGSOP 2 criteria. Usual gait speed (m/s) was performed by the subjects walking 4 m with usual speed and ≤0.8 m/s was defined as low walking speed. 3. Anthropometric measurement:

In all participants, height was measured using a stadiometer to the nearest 0.1 cm, weight was measured unclothed to the nearest 0.1 kg using a calibrated balance scale. Body mass index (BMI) was calculated by the weight (kg)/height (m2) equation.
