A multifaceted intervention model can give a lasting improvement of older peoples' nutritional status.

Objective: The purpose of this study was with a multifaceted intervention model improve the nutritional status of elderly people living in residential homes to increase their energy intake and to maintain improvements over time.

Setting: Three different municipal residential homes in the south-east of Sweden.

Participants: The study population consisted of 67 elderly people. A within-subjects design was used which means that the participants were their own controls.

Intervention: A multifaceted intervention model was chosen, which included education on both theoretical and practical issues, training and support for staff, and individualized snacks to the residents.

Measurements: Nutritional status was measured by Mini Nutritional Assessment (MNA), the consumption of food was recorded by the staff using a food record method for 3 consecutive days. The length of night-time fasting has been calculated from the food records.

Results: Nutritional status improved after 3 months of intervention and was maintained after 9 months. Weight increased during the whole study period. Night-time fasting decreased but not to the recommended level.

Conclusion: This study shows that it is possible by a multifaceted intervention model to increase energy intake including expanding snacks and thereby improve and maintain nutritional status over a longer period in the elderly living in residential homes. This result was possible to achieve because staff received education and training in nutritional issues and by provision of support during a period when new routines were introduced.
