Nutrition and psychological well-being among long-term care residents with dementia

ObjectivesTo examine the relationship between nutritional status of service housing and nursing home residents with dementia and their psychological well-being (PWB), and the associations of nutritional care and PWB.Design, participants and settingThis cross-sectional nutrition study was carried out in 2011. The study included all older long-term care residents (N=4966) living in nursing homes and service housing units (N=61) in Helsinki. The response rate of was 72%. Of the respondents, only persons who had a diagnosis of dementia were included in this analysis (N=2379).MeasurementsThe Mini Nutritional Assessment (MNA) tool and a structured questionnaire were used in assessing the residents. Six dimensions of PWB were included in the questionnaire. Information was also retrieved from medical records.ResultsOf residents 9% were wellnourished and 28% malnourished according to the MNA. PWB was good in 50% (score ≥ 0.80) and poor in 10% (score < 0.40) of the residents. Residents’ poor nutritional status, eating a little of the offered food, having meals alone and not having snacks were associated with poor PWB. Mild cognitive impairment was more often associated with poor PWB, whereas moderate or severe impairment was more often associated with good PWB.ConclusionNutritional status and nutritional care of residents with dementia were significantly associated with their psychological well-being. The residents suffering from malnutrition had the poorest psychological wellbeing.
