Multidomain Interventions for Elderly Individuals in Residential Structures

I-COUNT is a randomized controlled trial that will be conducted among residents in two residential facilities in Italy. Sixty participants will be enrolled in each residential facility (30 control group, 30 intervention group). During the first phase of the study, eligible residents of the participating LTCFs will be enrolled according to the following inclusion and exclusion criteria. Baseline evaluations will be based on a geriatric multidimensional assessment including body composition assessment, physical performance assessment, Mediterranean diet adherence assessment, psychological and neuropsychological evaluations. Blood, plasma, stool and urine samples will also be collected. In phase two, which will last 6 months, participants in the intervention group will undergo the planned interventions, while controls will be asked to continue with their usual activities. The physical activity will consist of three 40-minutes sessions per week, with personalized exercises prescribed by a physiotherapist and performed in small groups, under supervision. The cognitive training will be based on the computer program Remote stimulation for Cognitive Decline (RECODE), developed by the Department of General Psychology, University of the Padua, with two sessions per week. The intervention group will also receive functional foods (sourdough bread enriched with a vegetable matrix rich in polyphenols (olive leaves) and vegetables enriched with probiotics (artichokes)). In phase 3, participants will be reassessed at 3 months (gut microbiota only), and 6 and 9 months after the start of the intervention (selected biomarkers, nutritional and anthropometric status, psychological health, physical performance tests, cognitive function, acceptability of the technological monitoring and interventions).
