Associations Between Nutritional Status, Frailty and Health-Related Quality of Life Among Older Long-Term Care Residents in Helsinki

Objectives The aim of this study was to examine how nutritional status modifies the association between frailty and health-related quality of life (HRQoL) among older nursing home residents. We also investigated how residents' energy intake is linked to frailty score. Design and participants A total of 486 older (> 65 years of age) nursing home residents living in Helsinki, Finland were included to this cross-sectional study. Methods We collected data on the residents' background information, HRQoL by 15D, nutritional status by Mini Nutritional Assessment (MNA), frailty status (Fried's phenotype criteria; pre-frail: 1-2 criteria and frail: 3-5) and energy intake (one- or two-day food records). Results The frail residents were more often malnourished and had lower HRQoL than those in the prefrail group. Energy and protein intakes were significantly lower among frail women than prefrail women. Energy intake was linearly associated with frailty points. When residents in the frail and prefrail groups were divided according to their nutritional status, both nutritional status and frailty were associated with HRQoL, but there was no interaction. Conclusions Both nutritional status and frailty were associated with HRQoL, and lower energy intake indicated a higher frailty score. An adequate energy intake may promote residents' HRQoL and prevent frailty in long-term care.
