간단한 개요
The APPETITE Trial aims to investigate the efficacy of innovative plant protein fibre (PPF) products (developed in a previous workpackage) as part of a personalised diet with/out physical activity on appetite and incidence of undernutrition in older persons from three European countries at high risk of undernutrition.
상세한 설명
It is normal that dietary intake decreases as we age due to reduced activity and muscle mass. However, appetite is a key determinant of dietary intake, and poor appetite can result in undernutrition. In many instances, older adults do not recognise their appetite has decreased significantly as the decline is slow and progressive. Protein and fibre are often poorly consumed in the diets of older adults with decreased appetite, but essential for health and well-being. Interventions designed to increase appetite, or increase dietary intake despite a reduced appetite, should therefore be key to preventing undernutrition (i.e. protein-energy malnutrition as well as nutrient deficiencies). However, treatment strategies for poor appetite are not well-established.
In this multi-centre randomised controlled trial conducted in Ireland, Germany, and Italy, a two-by-two factorial design will define the individual and combined impact of two intervention conditions over 12 weeks: 1) personalised diet with focus on plant-based protein plus fibre; and 2) physical activity.
At each centre, 60 older adults (180 in total) will be randomly allocated to one of the following four groups over a 12 week period: 1) personalised diet plus physical activity program (PD + PA), 2) usual diet plus physical activity (PA), 3) personalised diet and no PA (PD), and 4) control (usual diet, no PA).
Using identical procedures, two testing visits will be completed before and after the 12 intervention or control period.

7-day physical activity score as assessed by ActivPAL v4.0 | 12-week change in physical activity score will be assessed using 7-day accelerometery data. This is a validated device that is installed onto an individuals thigh for continuous readings. The data generated describes the amount of time spent engaging in physical activities and sedentary activities, and gives an output score in MET.h (Metabolic EquivalenT hour). This is a measure of energy usage over and above what is required at rest, where 1MET is equivalent to oxygen uptake of 3.5ml/kg body weight/minute | To be assessed at baseline, prior to commencing the intervention, and during week 12 of the intervention or control period |

Assessed in circulating peripheral bloods at fasting, and at regular intervals postprandially (minute 30, 60, 90, 120, 150, \& 180). | To be assessed at baseline and following a 12-week intervention or control period |

Blood hormone and metabolite profile | 12-week change in fasting peripheral blood profile (insulin, leptin, glucose, amino acid, fatty acid) | To be assessed at baseline and following a 12-week intervention or control period |
Body composition by Bioelectrical Impedance Analysis (BIA) | Body composition will be assessed by BIA across all sites at baseline and post intervention. BIA is a quick non-invasive method of measuring body composition. Bioelectrical impedance analysis (BIA) measures body composition based on the rate at which an electrical current travels through the body. Body fat (adipose tissue) causes greater resistance (impedance) than lean mass and slows the rate at which the current travels. The device provides an output of absolute (Kg) and percentage (% of total mass) of fat mass (FM) and fat-free mass (FFM). | To be assessed at baseline and following a 12-week intervention or control period |
Appetite by Simplified Nutritional Appetite Questionnaire (SNAQ) | The SNAQ questionnaire is used to assess an older adults usual appetite. The SNAQ is a self-administered questionnaires adapted from the Appetite, Hunger and Sensory Perception questionnaire (AHSP), an appetite assessment tool validated among community-dwelling older adults. It consists of 4 multiple choice statements, where an individual reads the beginning of the statement and is presented with 5 options that best describe their situation. Each question derives a score between 1 - 5 with lower scores indicating poorer appetite. The questionnaire scores between 4 - 20 with scores \</= 14 indicating poor appetite. | To be assessed at baseline and following a 12-week intervention or control period |
Test meal palatability by Visual Analogue Scale (VAS) | Rating of the breakfast and lunch test meals by visual analogue scales (VAS). The VAS is a validated tool for assessing subjective sensory experience. On each 100-mm line, a question is asked relating to sensory aspects of the meal (E.g., How pleasant was the meal?). The subject will mark along the 100mm line where they feel their experience, in terms of the question, rests. On ether end of the 100mm line are opposing terms (E.g., "not at all", "extremely"). | To be assessed at baseline and following a 12-week intervention or control period |
Body weight (kg) | Body weight will be measure using a calibrated scales, shoes and heavy clothing removes, and recorded in kilograms. | To be assessed at baseline and following a 12-week intervention or control period |
Standing height (cm) | Height will be measured in centimetres using a stadiometer. Participants will be measured barefoot and asked to take a full inhalation prior to stepping out from the device. Measurements are taken at the peak of the inhalation. | To be assessed at baseline and following a 12-week intervention or control period |
Calf circumference (cm) | Calf circumference is measures using a non-stretch tape measure at the widest part of the calf muscle and recorded in centimetres. | To be assessed at baseline and following a 12-week intervention or control period |
Perception and evaluation of the trial | Questionnaire specific to the project. This questionnaire will serve to provide feedback about participants experience while enrolled on the project. The questionnaire will include a series of Likert style questions and open-ended questions. The purpose is the provide feedback to the study team on what participants liked or disliked about the experience. This will serve to inform future management of studies. | End of trial (up to 18-weeks) |
Body composition by Dual-energy X-ray absorptiometry (DXA) (sub-sample) | DXA will be performed on a sub-sample of participants enrolled on the APPETITE study. A DXA can involves a large scanning arm being passed over the body to measure compartments of the body structure. As the scanning arm is moved slowly over your body, a narrow beam of low-dose X-rays will be passed through the part of your body being examined. DXA is a quick and non-invasive scan that provides in-depth analysis of the main components of your body; fat, muscle and bone. | To be assessed at baseline and following a 12-week intervention or control period |
Motor Unit Signalling (sub-sample) | by electromyography (EMG) | To be assessed at baseline and following a 12-week intervention or control period |
Motor Unit Number | from muscle biopsy | To be assessed at baseline and following a 12-week intervention or control period |
muscle signalling related to muscle plasticity, metabolism, denervation and muscle capillarization (sub-sample) | This refers to the analyses of muscle biopsies. Biopsies will be taken using MEDAX/BF14100-C0; Bio-Feather with coaxial 14 g 10 cm. The following parameters will then be measured in the sample using western blot with specific antibodies for total proteins or by their activated phosphorylated form: 1) markers of denervation (AChR ; agrin/MuSK/Lrp4, NCAM, Myog); 2) markers of protein turnover (atrogin1, MURF1, LC3, BNIP3, Akt-dependent mTOR and FoxO); 3) markers of mitochondrial dynamics (OPA1, DRP1) and; 4) markers of energy metabolism pathways (AMPK and PGC1alpha). | To be assessed at baseline and following a 12-week intervention or control period |
Innate immune training of macrophages | Trained immunity describes the long-term functional reprogramming of innate immune cells after exposure to a primary insult which leads to an augmented response upon stimulation with the same ligand after returning to a non-activated state. Will habitual ingestion of plant protein combined with PA results in increased ability of macrophages to undertake innate immune train in adults over the age of 65. Effects will be quantified by comparing the presence of TNF alpha in human monocytes at baseline and following a 12-week intervention. | To be assessed at baseline and following a 12-week intervention or control period |
