Introduction:
Features of built environment have been related to behavior modification and might stimulate
cognitive activity with a potential impact on cognitive health in later life. The aim of this study is
to investigate cross-sectional associations between features of land use, cognitive impairment and
dementia and also explore urban and rural differences in these associations.
Methods:
Postcodes of the 7505 community-based participants (age 65+) in the Cognitive Function and
Ageing Study II (collected in 2008–2011) were linked to environmental data from government
statistics. A multilevel logistic regression was used to investigate associations between cognitive
impairment (defined as MMSE≤25), dementia (GMS-AGECAT organicity level≥3) and land use
features, including natural environment availability and land use mix, fitting interaction terms
with three rural/urban categories. Data were analyzed in 2015.
Results:
Associations between features of land use and cognitive impairment were not linear. After
5
adjusting for individual-level factors and area deprivation, living in areas with high land use mix
was associated with a nearly 30% decreased odds of cognitive impairment (OR: 0.72; 95%CI:
0.58, 0.89). This was similar, yet non-significant, for dementia (OR: 0.70; 95%CI: 0.46, 1.06). In
urban conurbations, living in areas with high natural environment availability was associated with
30% reduced odds of cognitive impairment (OR: 0.70; 95%CI: 0.50, 0.97).
Conclusions:
Non-linear associations between features of land use and cognitive impairment were confirmed in
this new cohort of older people in England. Both a lack and overload of environmental
stimulation may be detrimental to cognition in later life.
