Sarcopenia Definitions and Outcomes Consortium (SDOC) Criteria are Strongly Associated With Malnutrition, Depression, Falls, and Fractures in High-Risk Older Persons

Abstract

OBJECTIVES: Sarcopenia Definitions and Outcomes Consortium (SDOC) provides cut-points based on muscle weakness (low grip strength) and slowness (poor gait speed) for low-risk populations; however, it is unknown if these criteria apply to high-risk populations. We examined the association between SDOC criteria and important health status indicators in high-risk older persons. DESIGN: Cross-sectional study. SETTING AND PARTICIPANTS: 356 community-dwelling older persons (median age: 79 years, interquartile range: 73, 83; 75.2% women) attending a falls and fractures clinic in Melbourne, Australia. METHODS: Grip strength (hydraulic dynamometer) and gait speed (over 4 m) were used to define sarcop..
