Sarcopenia is an age-related decline in skeletal muscle mass, which depends on an assessment of muscle strength and muscle mass. The diagnostic definition of sarcopenia varies by region.
To determine the optimal diagnostic criteria for sarcopenia in a plateau population. Cut off values for the components of diagnostic algorithms for sarcopenia in plateau populations should consider altitude.
One hundred and fifty subjects aged > 60 years attending a tertiary comprehensive hospital in the city of Xining (elevation: 2260 m) between October and December 2018 were enrolled. Handgrip strength, muscle mass, and physical performance were measured. Sarcopenia was diagnosed according to the Asian Working Group for Sarcopenia (AWGS) 2019 criteria, Beijing criteria, and Lasha criteria.
Across diagnostic criteria, there were significant differences in the prevalence of sarcopenia in the overall population and stratified by gender. The prevalence of sarcopenia measured by the AWGS 2019 or Lasha criteria was significantly higher in female compared to male subjects. In males, the prevalence of sarcopenia measured by the Beijing criteria was significantly higher in subjects who identified as Han compared to Minority. In females, there were no significant differences in the prevalence of sarcopenia by ethnicity according to any criteria.
The Lasha criteria provided a lower prevalence of sarcopenia (males, 8.7%; females, 22.41%; overall, 14%) and were able to differentiate between males and females. The Lasha criteria are likely most appropriate for detection of sarcopenia in this plateau population. We recommend the Lasha criteria for detection of sarcopenia in Xining.
Core Tip: Cutoff values for the components of diagnostic algorithms for sarcopenia in plateau populations should consider altitude. We found the Lasha criteria provided a lower prevalence of sarcopenia (males, 8.7%; females, 22.41%; overall, 14%) and were able to differentiate between males and females. The Lasha criteria are likely most appropriate for detection of sarcopenia in this plateau population. We recommend the Lasha criteria for detection of sarcopenia in Xining.
