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

Abstract

Objective: Interventions to reduce the risk of cognitive decline and dementia largely focus on individual-level strategies. To maximize risk reduction, it is also necessary to consider the environment. With the majority of older people living in cities, we explored how urban environments could support risk reduction. Materials and Methods: In our qualitative study, we conducted semi-structured interviews with community members aged ≥65 years and stakeholders, all living in Leipzig, Germany. Interview guides were informed by the framework on modifiable risk factors for dementia of the Lancet Commission on Dementia Prevention, Intervention, and Care. Interviews were audio-recorded, verbatim-transcribed, and thematically analysed. Results: Community members (n = 10) were M = 73.7 (SD = 6.0) years old and 50% were women. Stakeholders (n = 10) were aged 39-72 years, and 70% were women. Stakeholders' fields included architecture, cultural/arts education, environmental sciences, geriatrics, health policy, information and technology, philosophy, psychology, public health, and urban sociology. Across interviews with both older individuals and stakeholders, three main themes were identified: (i) social participation and inclusion (emphasizing social contacts, social housing, intergenerationality, neighbourhood assistance, information and orientation, digital and technological literacy, lifelong learning, co-creation/co-design), (ii) proximity and accessibility (emphasizing proximity and reachability, mobility, affordability, access to health care, access to cultural events, public toilets), (iii) local recreation and wellbeing (emphasizing safety in traffic, security, cleanliness and environmental protection, urban greenery, climate change and heat waves, outdoor physical activity). Discussion: The design of urban environments holds large potential to create favourable conditions for community-dwelling individuals to practice lifestyles that promote brain health. Public policy should involve community members in cocreating such environments.

Environmental barriers matter from the early stages of functional decline among older adults in France

“…After this threshold, although the barriers increased the probability of having difficulties, the distinction between being assisted and coping with difficulties without assistance was not significant. Unlike other studies, we did not observe any significant associations with environmental barriers such as the presence of hills and slopes [ 17 ] or the absence/presence of public toilets [ 76 ]. Finally, regarding the immediate environment, using stairs/steps to get out lowered the probability of having no OADL restrictions, as found in several studies [ 12 , 14 ], with increasing pressure with the number of FLs.…”

Exploring English policymakers' attitudes towards dementia risk reduction: A qualitative study

“…[9][10][11][12] Notably, despite being explicitly focused on individual-level behaviour change, these studies identified some key motivators and barriers that were beyond an individual's control, such as social acceptability (of smoking), 9 workplace and family support, 9 and social disengagement. 12 To our knowledge, only one study 13 has sought explicitly to identify views on population-level dementia risk reduction.

Ethics, evidence, and the environment in dementia risk reduction

“…Röhr and colleagues from the Global Brain Health Institute have proposed a survey methodology with urban stakeholders. 4 This survey methodology could be used more widely across society so that policy changes might tend towards the cocreation (with stakeholders) of living and working spaces that are safer, more widely accessible, and are physically, mentally, and socially stimulating.…”
