Samenvatting

Background: To prevent and treat malnutrition and sarcopenia, a protein intake of 1,2-­‐1,5 gram per kilogram body weight per day is advised for elderly with acute or chronic diseases. The protein intake in hospitalized older adults is often insufficient. To prevent a low protein intake and its associated consequences, various nutritional interventions are established. These include the prescription of protein-­‐enriched diets, oral nutrition supplements or enteral nutrition. Despite these interventions, protein intake often remains inadequate. Therefore other nutritional interventions need to be developed, for example interventions with protein-­‐enriched ‘regular products’. The effect of a protein-­‐enriched yoghurt drink and bread on satiety and protein intake is still unknown. Objective: To investigate the effect of protein-­‐enriched ‘regular products ‘ on protein intake in older adults ≥55 years acutely admitted to hospital. Methods: The study was performed as a single blind randomized controlled trial and lasted three days. The intervention group received protein-­‐enriched bread and yoghurt drink and the control group received regular bread and yoghurt drink ad libitum. The quantity of the products given to participants and the waste returned were registered. Consumption of energy, carbohydrates, protein and fat were calculated per meal, in-­‐between meals, and for the whole day, using the Dutch Food Composition Table (NEVO table). An independent sample t-­‐test was used to compare the energy and protein intake between the intervention and control group. Results: Mean energy and protein intake of the intervention group (n=15) was 1530 ± 607 kcal and 67 ± 29 gram protein per day. In the control group (n=18) this was 1370 ± 400 kcal and 55 ± 16 gram protein a day. Although the overall intake of the participants in the intervention group was 160 kcal and 12,2 gram of protein higher, this was not significant. Of the males 23% and of the females 15% met the minimum protein requirements of >1,2 gram of protein per kilogram body weight a day. Conclusion: This is the first study, which examines the effects of protein-­‐enriched bread and yoghurt drink on food intake of older patients admitted to hospital. Although the intake of energy and protein in the intervention group was higher, this did not reach statistical significance. elderly, protein,
