Impact of Malnutrition on Low Muscle Mass in Community-Dwelling Older People in Singapore: Findings from the SHIELD study

摘要

Malnutrition contributes to loss of muscle mass. There is limited information on the prevalence of low muscle mass in community-dwelling older people who are (not) at risk of malnutrition. Factors associated with muscle mass are also not well characterized. This cross-sectional study aimed to determine the prevalence of low appendicular skeletal muscle mass index (ASMI; ASM/height ) in older people with normal nutritional status (Malnutrition Universal Screening Tool, MUST risk category = low) and those at risk of malnutrition (MUST risk category = medium or high), and to determine factors associated with ASMI.
