Clinical Trial Summary

Malnutrition has serious consequences: increased risk of falls, hospitalization and mortality. Malnutrition may accompany or aggravate another geriatric syndrome. The loss of muscle mass and function, called "sarcopenia" can itself lead to a loss of physical activity and therefore of independence. It has been reported that changes in the quantity or quality of food intake could influence the onset or progression of sarcopenia. Thus, an optimized oral diet covering the energy and protein needs of the elderly people living in a nursing home is a key element of the malnutrition prevention strategy. It could help slow down the loss of independence and have a direct impact on the occurrence of the complications mentioned above, and therefore on the use of care. In the elderly, as in the general population, the consumption of linoleic acid (LA), precursor of the omega 6 line, is too high, and that of alpha-linolenic acid (ALA), precursor of the omega 3 line, insufficient. The French National Institute against Cancer (INCA) 3 survey results indicate for the 65-79 year old population average ALA intakes of 0.9 g/d whereas the recommendation is 2 g/d. The same is true for long-chain n-3 PUFAs (eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA)). There are currently no recommendations specifically concerning nursing home populations. Only recommendations for non-frail people, over the age of 65, exist (ANSES, 2019). Experts recommend maintaining or even slightly increasing the consumption of portions of meat, eggs, fish, fruits and vegetables and dairy products. In the elderly, as in adults, an imbalance of n-6/n-3 PUFA intake or insufficient n-3 PUFA intake could facilitate the occurrence of cardiovascular diseases and certain cancers. The possible prevention of other pathologies more specific to the elderly, such as degenerative diseases, makes the consumption of n-3 PUFAs relevant in this population. Our approach aiming to cover the recommended dietary allowances (RDA) of n-3 PUFAs via the oral diet is therefore very original. An oral diet containing these different sources of fatty acid intake, of various origins, and other essential nutrients for the elderly, would have the advantage of meeting the nutritional objectives on the one hand, and of offering a wide range of tastes, flavors, and texture, allowing to optimize their consumption by nursing home residents, on the other hand. No study has yet evaluated the benefits of n-3 PUFA intake in dependent elderly people residing in nursing homes, moreover, using loss of independence as the main endpoint. The main objective of the trial is to evaluate the effect of an everyday diet containing n-3 PUFA intakes corresponding to the RDA (population > 65 years) compared to the usual diet (therefore uncontrolled) on the evolution of the loss of independence at 2 years of nursing home residents.

Clinical Trial Description

Prospective, controlled, randomized, multicentre, open-label clinical study comparing two groups of residents: - "Control" group: nursing home residents will receive an oral diet covering their nutritional needs in macronutrients as recommended for people over 70-65 years of age. - "Intervention" group: nursing home residents will receive an oral diet covering their nutritional needs in macronutrients as recommended for people over 65-70 years of age and including n-3 PUFA intake corresponding to the RDAs for people over 65 years. Residents will be included in clusters corresponding to the nursing homes in which they reside. The intervention will be delivered "at the nursing home level", i.e. all the residents included in the same nursing home will belong to the same "control" or "intervention" group. Notes: Note that a randomization of residents across the individual residents was not possible from a logistical point of view in a context of collective feeding in an institution. Actimetry analyzes as a marker of frailty. The investigators will conduct an ancillary study of actimetry analysis, on a sub-population of 60 residents (n=30 per group), in order to quantify physical activity and try to identify a possible trajectory of frailty that The investigators can correlate to the studied endpoints. To do this, the investigators will have a device consisting of an accelerometer and a barometer which will be positioned in a case around the neck (pendant) or failing that - if the resident expresses a preference - on the wrist (bracelet) to monitor participants' activities for 24 months. The nursing homes concerned will be selected for their proximity to Rennes and the homogeneity of the physical activities routinely offered to residents. The measures will be performed one week per month for 24 months. Main judgment criterion: Measurement of the level of independence by the ADL-LFS (Activities of Daily Living - Long Form Score) at 2 years from the RAI-MDS 3.0 questionnaire (Resident Assessment Instrument Minimum Dataset) LTCF (Long-Term Care Facilities). Secondary endpoints: Evaluate the effect of an everyday diet containing n-3 PUFA intakes corresponding to the RDA (population > 65 years) compared to the usual diet (therefore uncontrolled) on the following endpoints: 1. The evolution of anthropometric criteria and malnutrition 2. The risk of falling 3. The risk of an infection occurring 4. The evolution of the quality of life 5. Mortality 6. Healthcare consumption (hospitalizations and visits to the emergency room) 7. In a sub-population of 60 residents (n=30 per group) randomly selected among the participants of a few volunteer nursing homes and meeting the inclusion and non-inclusion criteria of the study. - The evolution of the quality of physical and sporting activity - The evolution of the quality of sleep Organic: 8. The biological profile of blood fatty acids and concentrations of ALA, EPA, DPA, DHA in red blood cells 9. Micro-CRP and albumin 10.
