SENior PRIorat: Participatory Research for the Improvement of Lifestyles, Quality of Life, Emotional Well-being, and Locomotor Abilities of Older Adults in the Priorat

Overview

Spain is experiencing a demographic shift towards an ageing population. In 2022, 20.1% of Spaniards were 65 or older, a figure projected to reach 30.4% by 2050. The trend is especially marked in rural areas, where outmigration of younger generations has left a high concentration of older residents. In Catalonia's Priorat county, the share of people aged 65+ already exceeds 20%, reaching 30%, and even 40% in some villages. The ageing process brings biological changes that reduce locomotor and cognitive abilities, limiting autonomy and quality of life. In rural areas, these challenges are compounded by social isolation and the lack of support networks, making older adults more vulnerable. Healthy lifestyle habits-such as balanced nutrition, regular exercise, avoiding tobacco and alcohol, and good sleep-can help delay dependence, lower the risk of chronic disease, and improve well-being. To promote these habits, social innovation must generate new services and approaches that address real needs, barriers, and motivations in adopting healthier lifestyles. Our group's research shows that participatory science is an effective tool to promote healthy ageing in rural settings. A three-month intervention co-designed with older adults in villages of ≤2,000 inhabitants led to improvements in locomotor function, measured through sarcopenia parameters, and enhanced quality of life in areas such as vitality, mental health, and social functioning. A distinctive feature of this approach is shared decision-making between residents and policymakers, ensuring that solutions are adapted to local realities. This fosters greater adherence, empowerment, and long-term sustainability of co-created strategies. This project is directly relevant to public policy through collaboration with the Consell Comarcal del Priorat, which represents 23 municipalities. Their recent report identified ageing as a major concern for both institutions and residents. The project's results can therefore guide health policies-decisions, plans, and actions-that address local needs while considering available resources and ensuring long-term sustainability. By focusing on health promotion and disease prevention, the project ensures that policies are evidence-based and subject to evaluation. The partnership with the Consell Comarcal also aligns with Sustainable Development Goal 3 (Health and Well-being) of the 2030 WHO Agenda and supports the "Health in All Policies" approach, fostering integrated strategies across sectors. The principal aim of the study is to evaluate the effectiveness of a participatory science intervention study in improving lifestyle habits (dietary habits, physical activity, substance use, and sleep quality), quality of life, emotional well-being, and locomotor capacities through the assessment of sarcopenia parameters (muscle strength, muscle mass, and physical function) in young-old adults (≥60 years) living in rural areas of the Priorat region (Catalonia, Spain). Specific Objectives: 1. To describe the health status of older people residing in the Priorat region by evaluating: lifestyle habits (diet, substance use, physical activity, and sleep), risk of malnutrition, functional capacity based on sarcopenia parameters, mental capacity (mental health and emotional well-being), and quality of life. 2. To improve lifestyle habits (diet, physical activity, sedentary behaviour, sleep habits, and substance use-alcohol and smoking), emotional well-being and personal relationships to avoid unwanted loneliness, quality of life, and locomotor abilities based on sarcopenia parameters (muscle strength, muscle mass, and physical function). 3. To reduce the risk of malnutrition. 4. To compare the health status of two groups: those aged 60-74 (young-old adults) and those aged 75 and over (older people). 5. To identify the needs, barriers, and motivations of older people through focus groups, including participants aged 60-74, those over 75, and stakeholders such as members of the public administration supporting the project. 6. To compare the differences in needs, barriers, and motivations identified by the young-old adults (60-74 years) and the older people (≥75 years). 7. To actively involve older participants in the co-creation of health promotion activities and an intervention designed for them and their peers. 8. To implement an intervention based on proposals generated during the co-creation process to improve their lifestyle (dietary habits, physical activity, substance use, well-being, and sleep behaviours), quality of life, and locomotor abilities. 9. To analyse environmental barriers, using the "Age-Friendly Cities and Communities Questionnaire (AFCCQ)", in the villages of the Priorat region that may influence the ability to maintain a healthy lifestyle and quality of life for people aged 60-74 and those aged 75 and over.
