Outline of Final Research Achievements

Malnutrition-Sarcopenia Syndrome (MSS) is the clinical presentation of both malnutrition and accelerated age-associated loss of lean body mass, strength, and/or physical performance. The aim of this study was to explore the relationship of MSS with all-cause mortality in nursing homes residents. The prevalence of MSS was 34.1% (n = 87). 41.2% (n = 105) of investigated participants were sarcopenia and 9.8% (n =25) were malnutrition. Thirty-eight residents (14.9%) were defined as robust. Lower values for ADL, more severe cognitive impairment, and lower physical function were observed for MSS than for sarcopenia. After a 12-month follow up 30 (16.0%) residents died. Kaplan-Meier survival curves were obtained for the 4 groups, showing that, at 12 months, MSS died more frequently than sarcopenia and robust.

Academic Significance and Societal Importance of the Research Achievements

本研究の結果より、施設入所している要介護高齢者において低栄養サルコペニアの割合が高いこと、サルコペニア単独よりも低栄養とサルコペニアを合併している低栄養サルコペニアの方が死亡リスクが高いことが明らかとなった。このことより、施設入所している要介護高齢者において、低栄養のみの改善や、サルコペニアのみの改善を目指すのではなく、両方の改善を目指す具体的な対策を構築する必要があること示唆された。
