Topic: Risk, prevention and care in population studies
Participants' age ranged from 45 to 87, 53% were women, and 26% were diagnosed with dementia (39% AD, 18% Lewy Body and 17% Frontotemporal Dementia; Table 1). In the whole sample, higher walkability was only associated with lower T-tau levels, with no associations observed for other outcomes (Table 2). Stratified analyses by area deprivation, showed that higher walkability was associated with lower T-tau and YKL-40 levels among individuals living in areas with higher ADI. Additionally, higher walkability was marginally associated with lower GDS-30 scores among individuals in medium-deprivation areas. Stratified analyses by cognitive status, showed that higher walkability was associated with lower Aβ burden only among individuals with dementia (Figure 1). Our findings link neighbourhood walkability to neurodegeneration, as well as neuroinflammation and depressive symptoms in highly and moderately deprived areas and to lower Aβ in individuals with a dementia diagnosis. Future research should explore the mediating mechanisms linking walkability to brain and mental health, including physical activity and mental health promotion. Urban planning strategies may consider both walkability and neighbourhood socioeconomic context to optimize cognitive and mental health outcomes in aging populations.
Key findings
- Participants' age ranged from 45 to 87, 53% were women, and 26% were diagnosed with dementia (39% AD, 18% Lewy Body and 17% Frontotemporal Dementia; Table 1).
- In the whole sample, higher walkability was only associated with lower T-tau levels, with no associations observed for other outcomes (Table 2).
- Stratified analyses by area deprivation, showed that higher walkability was associated with lower T-tau and YKL-40 levels among individuals living in areas with higher ADI.
- Additionally, higher walkability was marginally associated with lower GDS-30 scores among individuals in medium-deprivation areas.
- Stratified analyses by cognitive status, showed that higher walkability was associated with lower Aβ burden only among individuals with dementia (Figure 1).
Why it matters
This cross-sectional study found that living in a more walkable neighborhood was linked to lower levels of some markers of neurodegeneration and inflammation, mainly in more deprived areas, and to lower amyloid burden in people already diagnosed with dementia. It cannot show cause and effect, and the authors say future research should explore the mechanisms linking walkability to brain and mental health.

How this study scored 44/100
Published in a peer-reviewed journal, and it is a snapshot of people at one point in time. Scored zero for effect reported and randomised / blinded because the record does not state it. We have no data on senior author's track record, so that was left out: it earned 42 of the 96 points we could judge it on, which is 44 out of 100.
