Nutritional assessment and follow-up of residents with and without dementia in nursing homes in the Limousin region of France: a health network initiative

INTRODUCTION

Limousin in France has the second oldest regional population in Europe, with people over 65-years-old who have Alzheimer's disease accounting for more than 9%. In France as a whole, a large number of residents in nursing homes (NH) have dementia, leading to many nutritional problems. LINUT is a health network that assesses the nutritional status of elderly NH residents and provides support where necessary. Aims of the present study were to use this network to evaluate the nutritional status of NH residents with and without dementia and to review changes after 4 months of intervention.

METHODS

A cross-sectional survey was conducted by a doctor and a dietician at baseline (T0) and 4 months (T4) among residents at the 26 NH in Limousin that agreed to take part. The evaluation criteria included presence of dementia, depression and autonomy, weight, height, body mass index, Mini Nutritional Assessement (MNA™), and a 3-day survey of food intake.

RESULTS

The 346 residents assessed at T0 were aged 87.9±6.9 years, 83.4% were women, 66.8% had dementia, 53.3% were malnourished and 27.4% obese. Autonomy was not affected by obesity. Residents with dementia had a lower Activities of Daily Living score and a lower weight than non-demented individuals (2.2±1.2 vs. 2.7±1.7 p=0.03 and 60.1±16.3 vs. 64.7±20.0 kg p=0.03, respectively), were more often malnourished (56.1% vs. 46.4% p=0.004) and less often obese (22.0% vs. 39.1% p=0.004) but consumed more protein (62.6±17.8 vs. 58.2±16.9 g/d p=0.04, 1.1±0.4 vs. 1.0±0.4 g/kg/d p=0.005). Energy intake was at the lower limit of French recommendations (26.4±8.8 vs. >25.0 kcal/kg/d). Assessment of all residents at T4 showed improved MNA™ (+0.4 points/month p=0.02), protein intake (+3.3 g/d p=0.0007), and energy intake (+41.4 kcal/d p=0.01 and 0.1 kcal/kg/d p=0.03). Variations in prevalences of malnutrition and obesity were not statistically significant. MNA™ increased in the dementia group (+0.29±0.8 points/month p=0.003). All other changes were comparable, and nutritional status did not differ more between the two groups at T4 than at T0.

CONCLUSION

The prevalence of dementia was high in the population studied. Malnutrition was the main problem, particularly if residents had dementia. Protein intake was satisfactory, but energy intake often insufficient. The nutritional status of dementia patients improved after 4 months of follow-up, suggesting that effective action to support such services would be worthwhile.

Analysis of the food consumption of 87 elderly nursing home residents, depending on food texture

OBJECTIVES

Texture-modified food (chopped, mashed, or mixed) is often used for patients, and particularly for dependent elderly people facing swallowing disorders or dental problems. Food must be energy and protein enriched, because dilution is needed for preparation, and several meals like bread can be removed. The aim of the study was to assess the food consumption of residents in four French nursing homes depending on diet texture. DESIGN/PARTICIPANTS/MEASUREMENTS: The food consumption of 87 elderly people followed by a nutrition network, randomly taken and living in nursing homes in which texture-modified food enrichment was practiced was evaluated according to the type of texture used.

RESULTS

13.8% of residents had chopped texture and 29.9% mixed texture. There was no relationship between used food textures and nutritional status residents. Calorie consumption was below the recommended intakes for elderly nursing home residents in France, whatever the type of texture. The mixed texture had more protein than the normal one and was better balanced regarding fat intake. Protein consumption was at the lower limit of the recommended intakes. Residents in overweight were those whose food consumption relative to their weight was the lowest.

CONCLUSION

It seems important to check the mode of preparation of texture-modified food in nursing homes and to assess the real energy and protein consumptions of residents receiving this food.
