Only recently has fine-grained spatial and temporal data become available to study these effects, namely the MEDSAT dataset of English health, environmental, and sociodemographic information. Leveraging this new resource, we use a variety of variable importance techniques to robustly identify the most informative predictors across multiple health outcomes. We then develop an interpretable machine learning framework based on Generalized Additive Models (GAMs) and Multiscale Geographically Weighted Regression (MGWR) to analyze both local and global spatial dependencies of each variable on various health outcomes. Our findings identify NO2 as a global predictor for asthma, hypertension, and anxiety, alongside other outcome-specific predictors related to occupation, marriage, and vegetation. Regional analyses reveal local variations with air pollution and solar radiation, with notable shifts during COVID. This comprehensive approach provides actionable insights for addressing health disparities, and advocates for the integration of interpretable machine learning in public health.  \nCode—[github.com/maitraishaan/VI-and-IML-MEDSAT](github.com/maitraishaan/VI-and-IML-MEDSAT)[ ](github.com/maitraishaan/VI-and-IML-MEDSAT)Datasets—[mediatum.ub.tum.de/1714817](mediatum.ub.tum.de/1714817)  \nIntroduction  \nRecent increases in the prevalence of chronic diseases such as diabetes and hypertension (Jia 2022) along with empirical evidence of the health risks associated with climate change (Obradovich et al. 2018) highlight the pressing need to understand what environmental and sociodemographic features impact health. Only recently has a very detailed dataset (MEDSAT, Scepanovic et al. 2023) become available that integrates health determinants, including sociodemographic, environmental, and geographic features, withoutcome-related prescription data as a proxy for health outcomes. It offers an unprecedented opportunity for exploring these relationships in close detail across England – if we have the trustworthy tools to do it.  \n*These authors contributed equally.  \nCopyright © 2025, Association for the Advancement of Artificial Intelligence ([www.aaai.org](www.aaai.org)). All rights reserved.  \nPrior work has utilized other integrated datasets to uncover relationships between environmental or sociodemographic variables and health outcomes, but these studies tend to 1) rely on a single variable importance method, 2) fail to measure spatially local relationships, and 3) do not create tools that provide extremely interpretable and auditable models. A group of recent works have focused on demonstrating how air pollution triggers respiratory and cardiovascular diseases (Annesi-Maesano et al. 2021; RazaviTermeh, Sadeghi-Niaraki, and Choi 2021; Ravindra et al. 2023; Liu et al. 2024) . Other works have aimed to determine risk factors for depression and anxiety (Qasrawi et al. 2022; Byeon 2021; Elshawi, Al-Mallah, and Sakr 2019) . These studies have a primary limitation: the lack of a comprehensive dataset that would enable the disentangling of contributions from multiple factors to health outcomes.
