In order to implement effective actions to prevent the loss of autonomy in older adults, which has become a major issue, a crucial first step is to identify the conditions that influence it. Current approaches to health increasingly rely on a comprehensive and multidisciplinary vision, in line with so-called "socio-ecological" approaches, which argue that health is influenced by a wide range of interacting factors. However, these interdependencies and interactions are still poorly understood. It therefore seems necessary to move beyond the isolated analyses of risk factors carried out to date and adopt a holistic/systemic vision by examining both individual and environmental factors, as well as their interactions, which together can contribute to functional decline or the development of pathologies in older adults and those aging.
The aim of this study is to identify the relationships between intrapersonal and environmental factors, and their cumulative, moderating, and mediating effects on the health of older adults and those experiencing aging.
To this end, participants will be asked to complete a series of questionnaires and perform tests on various health-related dimensions. The evaluation criteria are: health, autonomy and quality of life, individual factors (health practices (e.g., physical activity), psychological characteristics (e.g., personal beliefs), socioeconomic status, etc.) and environmental factors (accessibility, living environment).

Autonomy
Autonomy is assessed using the Instrumental Activities of Daily Living (IADL) Scale of Lawton. The scale comprises 8 items. The total score ranges from 0 to 8, with a higher score being better.
Care consumption, health behavior and psycho-socio-environmental characteristics
The evaluation criteria will be, on the one hand, the same individual and environmental factors (e.g., personal beliefs, socio-economic status, accessibility, physical activity, diet) mentioned previously for the main objective, and on the other hand, the consumption of care (number and types of care).
Measure Quality of life
Quality of life is assessed using the EuroQol at 5 dimensions (EQ-5D) questionnaire. The scale comprises 5 items. Each item is scored from 1 "no problem" to 3 "severe problem". The total score ranges from 5 to 15 with higher score indicating a worse outcome.
Physical functional force (physical measure)
: Physical functional force is assessed using the 5 sit-to-stand test wich consists of asking the participant to stand up and sit down from a chair 5 times as quickly as possible. The outcome is the time taken to complete the test, and the unit of measurement is seconds.
Sarcopenia (physical measure)
Sarcopenia is assessed using the SARC-F questionnaire comprising 5 items assessing force, walk difficulties, stand up capacities, climb stairs capacities and fall. Each item is scored from 0 to 2. The total score ranges from 0 to 10 with higher score indicating a worse outcome.
