Nutritional Status Among Older Adults. Risk Factors and Consequences of Malnutrition
The aim of the study is to estimate the prevalence of malnutrition among older adults admitted to hospital and to analyse predictive factors for malnutrition. Further, the aim was to analyse the association between nutritional status and all-cause and cause-specific mortality.
The hypothesis is that malnourished patients have a higher mortality then well-nourished patients after three years.

- Nutritional status according to the screening instrument Mini Nutritional Assessment (MNA) [ Time Frame: 30 minutes ] [ Designated as safety issue: No ][The 18 questions in the MNA instrument are weighted, and the threshold values of the instrument categorize patients into three nutritional status groups: well-nourished (MNA score 24-30), at risk of malnutrition (MNA score 17-23.5), or malnourished (MNA score <17).
- All-cause mortality [ Time Frame: All-cause mortality was analyzed after median 3.5 years. ] [ Designated as safety issue: No ]Survival was calculated from the date of the MNA screening to the date of death.
- Cause-specific mortality [ Time Frame: Cause-specific mortality was analyzed after median 4.7 years. ] [ Designated as safety issue: No ]Survival was calculated from the date of the MNA screening to the date of cause-specific death.
