To better understand how diet influences health during aging, the French National Research Institute for Agriculture, Food and the Environment (INRAE) is working with the Gérontopôle Auvergne-Rhône-Alpes on a project called Part'AGE. Part'AGE is a participatory research project where researchers want to recruit 1,000 people aged between 55 and 75 years, men and women, living in Auvergne-Rhône-Alpes in urban or rural areas. The goal is to study eating habits and state of health. To do this, researchers will examine many factors that can influence them, such as physical activity, overall health, consumption patterns or territories. Researchers will collect detailed information to classify participants into different groups (food typologies) based on their eating habits and state of health. With this distribution, the goal is to be able to give each group personalized nutritional advice to age in better health.
To participate in the study, the participants will need to collect a few drops of blood from the end of the finger, a urine sample, and do some tests (mobility, oral health). It will also be necessary to fill out questionnaires on eating habits, physical activity, and other aspects that may influence health. The benefices for to participants will be to contribute to nutrition research and to receive personalized feedback and advices on eating habits.
Male or female (balanced sex ratio or at least 40% male to 60% female) in complete autonomy at home.
55 to 75 years old, including the limits
20 ≤ BMI ≤35 kg/m2
Available to carry out the entire protocol, including self-sampling (not sensitive to the sight of one's own blood for example) and agreeing to stop taking food supplements during the study.
Weight loss ≥ 5% in 1 month or ≥ 10% in 6 months or ≥ 10% compared to usual weight
Treated diabetes
Sub-acute pathology (flu, gastroenteritis, bacterial infection, etc.) or trauma (fracture, surgical intervention, etc.) in the 30 days prior to inclusion.
Hepatocellular insufficiency,
Participants will be recruited from the Auvergne-Rhône-Alpes region, taking care to recruit both urban and rural people.
Ecologic or community
Cross-sectional
survey on eating behavior, physical activity and health status
Other interventionParticipatory research: participants will carry out surveys, functional tests and urine and blood sampling completely independently
Classification of our study population into 5 dietary typologies associated with more or less successful aging
1. Typology "at risk of malnutrition": volunteers who do not cover their daily protein-energy needs, i.e. having daily protein-energy intakes estimated by food consumption data lower than the needs estimated by the Mifflin and St Jeor equation (based on anthropometric and physical activity measurements). 2. "Balanced diet without cardio-metabolic risk" typology: volunteers covering their daily protein-energy needs, with an aHEI (Alternative Healthy Eating Index) score greater than 80 and with a waist circumference less than or equal to 94 cm for men and 80 cm for women. 3. "Diet to improve without cardio-metabolic risk" typology: volunteers covering their daily protein-energy needs, with an aHEI score less than or equal to 80 and with a waist circumference less than or equal to 94 cm for men and 80 cm for women. 4. "Balanced diet with cardio-metabolic risk" typology: volunteers covering their daily protein-energy needs, with an aHEI score greater than 80 and with a waist circumference
Blood parameters and waist-to-hip ratio
Assessment of glucose, C-peptide, triglycerides, cholesterol, amino acids, prealbumin and CRP levels in fingertip blood collected at home, and waist-to-hip ratio.
Assessment of dietary habits and choices
Assessment of dietary habits and choices by: polyphenol-targeted food frequency questionnaire, appetite questionnaire (Council on Nutrition Appetite Questionnaire, CNAQ), questionnaire on food expectations and choices, on culinary practices, supply, and nutritional perceptions. Assessment of diet quality with various scores (DQI, PNNS-GS, DII) and post-hoc analyses.
Assessment of physical capacities and physical activity
Assessment of physical capacities and physical activity with the chair rise test, calf circumference measurement and two questionnaires (IPAQ, and RPAQ/ONAPS) aimed at assessing physical activity and sedentary lifestyle.
Assessment of several dimensions of health
Assessment of several dimensions of health: 1) oral health (masticatory performance, number of posterior functional units, GOHAI questionnaire on quality of life related to oral health, EAT-10 questionnaire on dysphagia/swallowing, XI questionnaire on dry mouth and the CIF questionnaire on oral dysfunctions); 2) intestinal health (intestinal transit questionnaire and intestinal comfort questionnaire (IGQ); 3) various aspects of quality of life (stress, fatigue, anxiety, sleep, addictions, etc.).
