People have a preference for, and feel better in, beautiful natural environments. However, there are no epidemiological studies on the association between neighborhood beauty and neuroimaging measures. We aimed to determine association between neighborhood beauty and regional brain volume. Participants were 476 community-dwelling older adults from...

... neighborhood beauty was significantly and positively correlated with objectively measured green spaces (r = 0.31, p < 0.001); blue spaces, including paddy fields; (r = 0.28, p < 0.001); and plant diversity (r = 0.29, p < 0.001), but negatively correlated with objectively measured blue spaces that did not include paddy fields (r = −0.13, p = 0.006) ( Table 2). Objectively measured green space was highly positively correlated with plant diversity. ...Context 2
... adjusting for residential area and childhood exposure to neighborhood nature, these associations were lower but remained significant (Model 3). Analyses stratified by residential area showed that the association between subjective neighborhood beauty and regional brain volume tended to be stronger in participants who lived in the mountainous area than in participants who lived in the downtown area (Supplementary Table S2).
