While hospitalized and after discharging, older adults\u2019 nutritional status often continues to deteriorate. Many nutritional intervention studies have been conducted to find ways to improve health-related outcomes for older adults at nutritional risk. However, findings have been inconsistent; thus, we aimed to investigate whether we could positively affect outcomes with a more intense nutritional intervention, lasting for a longer period than in previous studies.<\/p>\n<p><strong>Methods:<\/strong> Participants (N=106) were older adults at nutritional risk discharging to independent living from hospital. Participants were randomized to either an intervention- or a control group. The intervention group (n=53) received nutritional therapy by a dietitian and free energy- and protein rich foods, snacks, and oral nutrition supplements for six months. The control group (n=53) discharged according to standard care from the hospital but also received a pamphlet with nutritional information for older adults. Measures were conducted at discharge (baseline) and at the end of the study (six months). For the secondary analysis we collected information on the use of hospital services (up to 24 months) from the Icelandic electronic hospital registry.<\/p>\n<p><strong>Results:<\/strong> We found a statistically significant increase in bodyweight and in energy- and protein intake in the intervention group, but a decrease in the control group. Cognitive function, physical function, self-rated health, and quality of life significantly improved in the intervention group. Depressive symptoms increased significantly in the control group, and they rated their own health worse than at the beginning of the study. Improvements in cognitive function, self-rated health and depressive symptoms were significantly related to increases in bodyweight in a linear way. The control group had a significantly higher proportion of at least one readmission in comparison to the intervention group at one and six months. Readmissions were significantly more frequent in the control group than in the intervention group at one, six and 12 months and the control group also had a significantly longer length of hospital stay at one, six, 12 and 18 months.<\/p>\n<p><strong>Conclusion: <\/strong>Appropriate nutritional therapy, provided by a dietitian can significantly benefit the quality of life and independence of older adults at nutritional risk or malnourished, whilst also having great benefits for society as a whole.<\/p>\n<p><strong>Um doktorsefni\u00f0<\/strong><\/p>\n<p>Berglind Soff\u00eda \u00c1sbj\u00f6rnsd\u00f3ttir Bl\u00f6ndal er f\u00e6dd \u00e1ri\u00f0 1977 \u00ed Reykjav\u00edk.
