How can urban environments support dementia risk reduction? A qualitative study

Area of Science:

• Gerontology
• Urban Planning
• Public Health

Background:

• Cognitive decline and dementia interventions often overlook environmental factors.
• Urban settings house the majority of older adults, presenting opportunities for risk reduction.
• The built environment significantly influences lifestyle choices impacting brain health.

Purpose of the Study:

• To explore how urban environments can be designed to support cognitive health and reduce dementia risk.
• To identify key environmental features that promote brain-healthy lifestyles in older adults.
• To inform public policy on creating dementia-friendly cities.

Main Methods:

• Qualitative study using semi-structured interviews with community members (≥65 years) and stakeholders in Leipzig, Germany.
• Interview guides based on the Lancet Commission's framework for modifiable dementia risk factors.
• Thematic analysis of verbatim-transcribed interviews.

Main Results:

• Three main themes emerged: social participation and inclusion, proximity and accessibility, and local recreation and well-being.
• Social inclusion factors include intergenerationality, neighbourhood support, and lifelong learning.
• Accessibility encompasses mobility, affordability, and access to healthcare and cultural events.
• Well-being aspects involve safety, cleanliness, urban greenery, and climate considerations.

Conclusions:

• Urban environmental design offers substantial potential for promoting brain health in community-dwelling older adults.
• Collaborative, community-driven approaches are essential for developing effective urban interventions.
• Public policy must integrate community input to create supportive urban settings for cognitive health.
