Objectives: With the aim to reduce health inequality, an intervention has been designed to promote self‐management, health literacy and social capital among older people who perceived their health as fair or poor and are living in urban socioeconomically disadvantaged areas with the aim of improving their self‐perceived health. Secondarily, the efficacy of the intervention will be analysed in terms of increasing self‐management, health literacy and social capital (social support and social participation), quality of life, mental health and healthy lifestyles.
