Özet

Aim: We aimed to report on reference values for “handgrip strength” and “muscle-mass” parameters in accordance with European Working Group on Sarcopenia in Older People (EWGSOP) sarcopenia definition in Turkish population. As a secondary outcome, we aimed to report the normal values of usual gait speed, calf circumference and middle-arm circumference in the healthy adult Turkish population.

Methods: Turkish subjects between 18–39 years of age with no known disease and chronic drug usage were asked to participate in our study. Body composition was assessed with body impedance analysis via BC 532 model body analysis monitor. Skeletal-muscle-index was calculated as the BIA predicted absolute skeletal muscle mass/height2. Grip strength was assessed with the JAMAR hydraulic hand dynamometer. The cut-off thresholds of the studied parameters were defined as the mean-2SD of the values of the reference study population.

Results: A total of 282 participants (175 male, 107 female) were included in our study. Mean ages were 27±4.5, 26±4.8 years; usual-gait-speeds were 1.4±0.2 m/s, 1.4±0.2 m/s; handgrip strengths were 53.5±7.5 kg, 33.0±5.3 kg; skeletal-muscle-indexes were 11±0.9, 9±0.8 kg/m2; calf circumferences were 37.4±3.0 cm, 34.6±2.7cm, middle-arm circumferences were 29.2±2.8 cm, 24.2±2.2 cm, in males and females, respectively. The cut-off thresholds for handgrip strengths were 38.5 kg and 22.5 kg; skeletal-muscle-index were 9.2 kg/m2 and 7.4 kg/m2, in male and female subjects, respectively.

Conclusions: Our study suggests that the cut-off thresholds for handgrip strength and skeletal-muscle-index are highest in the Turkish population. By highlighting the significant differences in between the populations, this study underscores the call of EWGSOP’s urgent need to obtain good reference values for populations around the world.
