OBJECTIVES:  Malnutrition has a negative affection for elderly people’s health and quality of life, yet it is not an uncommon phenomenon in elderly homes. The aim of our study was to assess the nutritional status and factors affecting their nutritions of elderly people living in homes in Kalocsa, Hungary. We were also assessing the connection between nutritional status of the elderly, their mental health and other diseases. METHODS:  A longitudinal, quantitative study was carried out with non-probability, targeted sampling at the eldery nursing home in Kalocsa, Hungary between 2015. 08. 04. and 2015. 12. 12. Our sample consists of people above 60 years (N=100). Data collection was made with a self-made questionnaire, document analysis, anthropometric measurements and standard questionnaires (MUST, MNA-SF, MNA, SNAQ65+, MMSE). SPSS 22.0 was used for calculating descriptive statistics, χ-test, paired samples t-test and ANOVA (p<0.05). RESULTS:  Mean age of responders is 81.24±8.758 years. Prevalence of malnutrition in the sample: MNA3=8%; MNA-SF3=11%; MUST3=13%; SNAQ65+3=14%. Nutritional status of elderly people decreased significantly according to MUST and MNA-SF (p<0.05). There is a strong connection between the presence of dementia and malnutrition according to MNA (p=0.018). Nutritional status is influenced by hypertonia (p<0.05), gastrointestinalis (p=0.008), psychiatrial condition (p=0.037), bone and muscle disorders (p=0.008), appetite (p<.,001) ability to swallow (p<0.05) and self-sufficiency (p<0.001). CONCLUSIONS:  Nearly one quarter of elderly living in homes suffers from malnutrition. Malnutrition or the risk of it occurs more frequently in people with dementia – this result is similar to the findings of Malara et. al in 2010.
