Clinical Trial Summary

The purpose of this study is to determine whether a marine protein hydrolysate given as a supplement can prevent age related loss of muscle mass and loss of physical function in frail elderly. The study will recruit elderly living at home with help from municipal health care services, and a secondary goal of the study is to describe food habits, seafood intake and nutritional status in this group of patients.

Edit: the recruitment procedure was changed in august 2017, to include elderly without help from municipal health care services. Participants are now recruited trough media and organizations for elderly, and these changes in recruitment procedure was approved by the ethics committee august 2017.


Description:

The overall objective in this project is to study how nutrition influences frailty and physical function in home-dwelling elderly.

The study will seek to answer the following hypotheses (RCT):

1. Sarcopenia as measures by SPPB, grip strength, antropometry and gait speed is significantly associated with nutritional status and intake of protein in frail elderly.

2. A supplement of 3000mg of marine peptides pr. day in 12 months in the intervention group will improve the score on SPPB and other sarcopenia-related outcomes like grip strength, antropometric measures or gait speed compared to the placebo group.

To supplement the results of the RCT, interviews will be performed with selected participants to answer the following question:

- How do frail elderly describe their own nutritional status and need of help from municipal health care service related to nutrition? The data collection will be made in the participants' home at baseline and after 6 and 12 months. The patients will complete the Short Physical Performance Test (SPPB), Grip Strength measurement and anthropometric measurements (weight, height, calf circumference and mid-arm circumference). Assessment of nutritional status will be made by Mini Nutritional Assessment (MNA). Seafood intake and protein intake will be assessed by a food frequency questionnaire based on previously used and validated questionnaires. Daily energy intake will be estimated by a 24-hour multiple pass recall of food intake. Health related quality of life will be assessed by the EQ-5D-5L questionnaire (EuroQol). In addition, the participants will be asked to take blood tests to be analyzed for vitamin D, nutritional and inflammation markers.

Sample size and statistical power calculation The main outcome of this study is physical performance, measured on a 12 point ordinal scale; the SPPB. In accordance to previous studies, a clinical meaningful change in score on this scale is 0,4 - 1,5 points. Based on mean values and SD from the mentioned study, power was computed with SPSS (IMB) Power Sample for t-test of independent samples. The criterion for significance (alpha) has been set at 0,050 and the test is 2-tailed. With a sample size of 39 in each of the two groups, the study will have a power of 80% to yield a statistically significant result. This computation assumes a difference between groups of 0.9 points. As the participants are frail and of old age, we expect a dropout/missing frequency of 20 %, thus we should have 50 participants in each group.

Statistical analyzes The null hypothesis is that there is no difference between intervention and control group, in change of physical performance across multiple test attempts. Linear mixed model will be used to detect differences in treatments across multiple test attempts. Linear mixed model and ordinal regression models will be used to explore the relationship between nutrition and physical performance at baseline.

In-depth interviews Interviews will provide a deeper understanding of potential results in the RCT. Fifteen to twenty participants will be selected to the interviews by purposeful recruitment, based on results from the RCT study. The interviews will be transcribed and analyzed using qualitative content analysis.

Ethical consideration This project was approved by the Regional Committee in Ethics in Medical Research in Mid- Norway. The investigators do not anticipate this project causing any harm or discomfort to the participants, and will make sure that our participants participate in the study voluntarily. Participants will be given both oral and written information about the study twice before they give their consent to participate. First, they will receive information from their home care nurse, and if they agree to receive a call or visit from the researcher, they will have the opportunity to ask questions before signing the written consent. Participants not receiving municipal health care services sign their consent at the first visit. Furthermore, they will be informed about the possibility to withdraw from the study without any consequences at any time.

The project will have considerable benefits for this patient group. Increased knowledge of the nutritional status and protein intake in the patient group may facilitate nutritional interventions to prevent loss of physical function, potentially leading to increased independence and delayed need of residential institution. Results from the RCT may be transferable to other patient conditions where muscle atrophy is expected, e.g. inactivity after injuries, bed rest after surgery, or in intensive care units.

Dietary Supplement:
Marine Protein hydrolysate
The participants will take the supplement in form of tablets and will be instructed to take five tablets twice a day, preferably in relation to meals, however, not the dinner meal. Each tablet contains 300 mg of marine protein hydrolysates (Nx6.25). The tablets are produced by Flexipharma AS.
Placebo
Placebo tablets will be made based on gum arabicum. The tablets are produced by Flexipharma AS.
