摘要

面对人类引起的环境变化对心理健康和行为影响的大量证据,我们对环境因素(即暴露体和大脑)的主要影响和相互作用的了解仍然有限。我们试图利用来自成年社区居民(n=2672;平均年龄为 63±10 岁)的地理参照大规模脑成像和心理测量数据来填补这一知识空白。为监测大脑解剖结构,我们从具有磁共振成像的嵌套子集(n=944)中提取形态测量特征。利用迭代分析策略,我们测试了地理空间编码的暴露组因素对大脑解剖和心理测量之间关联的调节作用,结果表明,个人的焦虑状态和社会心理功能是与城市暴露组相关的心理健康特征之一。焦虑状态较高和当前社会心理功能较低的集群在空间上与较低的植被密度和较高的空气污染相吻合。单变量多尺度地理加权回归确定了个人焦虑状态、社会心理功能和总体认知水平与植被密度、空气污染和边缘网络结构之间的空间尺度关联。此外,多尺度地理加权回归交互模型揭示了空间限制的暴露组特征,这些特征对大脑-心理测量/认知表现之间的关系具有调节作用。我们在个体水平上测试暴露组因素对大脑和行为的作用的原创性发现,强调了环境和空间背景在调节整个成人生命周期的大脑-行为动态中的作用。

Large-scale georeferenced neuroimaging and psychometry data link the urban environmental exposome with brain health.

In face of cumulating evidence about the impact of human-induced environmental changes on mental health and behavior, our understanding of the main effects and interactions between environmental factors - i.e., the exposome and the brain - is still limited. We seek to fill this knowledge gap by leveraging georeferenced large-scale brain imaging and psychometry data from the adult community-dwelling population (n=2672; mean age 63±10 years). For monitoring brain anatomy, we extract morphometry features from a nested subset of the cohort (n=944) with magnetic resonance imaging. Using an iterative analytical strategy testing the moderator role of geospatially encoded exposome factors on the association between brain anatomy and psychometry, we demonstrate that individuals' anxiety state and psychosocial functioning are among the mental health characteristics showing associations with the urban exposome. The clusters of higher anxiety state and lower current psychosocial functioning coincide spatially with a lower vegetation density and higher air pollution. The univariate multiscale geographically weighted regression identifies the spatial scale of associations between individuals' levels of anxiety state, psychosocial functioning, and overall cognition with vegetation density, air pollution and structures of the limbic network. Moreover, the multiscale geographically weighted regression interaction model reveals spatially confined exposome features with moderating effect on the brain-psychometry/cognitive performance relationships. Our original findings testing the role of exposome factors on brain and behavior at the individual level, underscore the role of environmental and spatial context in moderating brain-behavior dynamics across the adult lifespan.
