Prior studies typically have only examined a limited number of exposures and have rarely distinguished HDP subtypes (ie, gestational hypertension, preeclampsia, eclampsia, and chronic hypertension with or without superimposed preeclampsia) or accounted for residential mobility during pregnancy. To address these gaps, we conducted a spatial and contextual exposome study of HDP using linked electronic health records (EHR) and vital statistics data in Florida. We analyzed 686 412 singleton pregnancies conceived between 2013 and 2018, using computable phenotyping to distinguish HDP subtypes. A total of 245 spatial and contextual exposome measures spanning natural, built, and social environments were linked to residential histories from conception through gestational week 19. Using a two-phase double machine learning (DML) framework with exposure-specific, directed acyclic graph-guided confounder adjustment, we conducted discovery and replication analyses, followed by multi-treatment DML to estimate effect sizes. In Phase 1, 26 exposome measures replicated for gestational hypertension and 34 for overall HDP. In Phase 2, 12 measures remained associated with gestational hypertension and 11 with overall HDP, including air toxicants, meteorological factors, ultraviolet radiation, neighborhood crime indicators, environmental noise, and proximity to coastline. No exposures passed multiple-comparison thresholds for preeclampsia or eclampsia. These findings demonstrate that the spatial and contextual exposome contributes to HDP in a subtype-specific manner. Integrating EHR-linked phenotyping, residential mobility, and causal machine-learning methods offers a scalable framework for identifying environmental factors relevant to HDP prevention.</p>","PeriodicalId":73005,"journal":{"name":"Exposome","volume":"6 1","pages":"osag009"},"PeriodicalIF":0.0,"publicationDate":"2026-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13017162/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147576718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We then maintained the animals under standard conditions for 5 months and compared them to control adults never exposed to BPF. In addition to sequencing the gut microbiome, we profiled six different tissues and serum by metabolomics and lipidomics. Strikingly, we found widespread alterations in metabolites and lipids throughout the animal that were both sex and tissue specific. For example, over 60 lipid species were depleted in the livers of BPF-treated females but no changes were observed in male livers. At the tissue level, BPF treatment altered fatty acid oxidation uniquely in skeletal and cardiac muscle. This study shows that transient exposures limited to the developmental phase of life can induce metabolic abnormalities later in adulthood.

We used data from the 1999-2000 and 2001-2002 cycles of the National Health and Nutrition Examination Survey (NHANES) to examine whether health insurance status is associated with the chemical exposome and whether being insured modifies relationships of environmental exposures with epigenetic aging biomarkers of morbidity and mortality (GrimAge2 and DunedinPoAm). Among 2315 adults aged 50 - 84 years, we evaluated 64 chemical exposures. In covariate, socioeconomic status-adjusted models, being insured compared to being uninsured was marginally associated with 0.21-SD lower blood lead levels (95% CI: -0.39, -0.04, <i>P </i>= 0.03) and 0.29-SD higher PCB180 levels (95% CI: 0.003, 0.57, <i>P </i>= 0.048). In leukocyte- and covariate-adjusted models, insurance attenuated the relationship of lead with GrimAge2 (Insured: β = 0.08-years, 95% CI: -0.08, 0.24; Uninsured β = 0.65-years, 95% CI: 0.11, 1.20; <i>P</i> _interaction = 0.04) and DunedinPoAm (Insured: β = 0.001, 95% CI: -0.002, 0.003; Uninsured β = 0.01, 95% CI 0.0001, 0.02; <i>P</i> _interaction = 0.047). Similar trends were also observed for cadmium, cotinine, and PCB180 but not statistically different between insurance categories. These findings suggest that health insurance may serve as a protective factor against the biological aging impacts of certain environmental exposures, possibly through improved access to exposure monitoring and preventive/therapeutic care. While not a substitute for environmental policy or exposure remediation, insurance may represent a small, complementary, and more immediately actionable tool to help reduce harm. However, given the small magnitude of model estimates, results should be interpreted with caution regarding their practical significance.</p>","PeriodicalId":73005,"journal":{"name":"Exposome","volume":"6 1","pages":"osaf015"},"PeriodicalIF":0.0,"publicationDate":"2025-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12812204/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146004722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While recent advances in exposomics have enabled systematic characterization of the exposome, the integrated compilation of all physical, chemical, biological, and psychosocial influences that affect biology and health, identifying and developing sensitive biomarkers remains a critical challenge. The human eye offers unique potential for non-invasive biomarker discovery. Ocular biomarkers can be utilized not only for diagnostics and therapeutic responses of ocular diseases, but also for monitoring environmental exposures and predicting systemic health outcomes. Retinal imaging modalities such as color fundus photography, optical coherence tomography, and optical coherence tomography angiography capture biomarkers linked to environmental exposures and systemic conditions like cardiovascular and neurodegenerative diseases, a field known as oculomics. Similarly, ocular fluids, such as tears, aqueous humor and vitreous humor, may also reflect pollution-induced oxidative stress and inflammation and systemic health conditions. This paper summarizes current evidence on how ocular biomarkers can bridge environmental exposures and systemic health outcomes, and proposes future research directions using state of the art methodologies such as exposome-wide association studies, high dimensional mediation analysis, and multi-modal foundation models. Despite encouraging progress, significant challenges remain, including the need for large and standardized datasets, rigorous validation, and ethical safeguards to ensure equitable application.

The incorporation of new technologies, like omics, genotypes, Electronic Health Records, georeferencing and AI, into public health is attractive; however, the thesis of this Commentary is that the use of the exposome approach for precision prevention needs to be examined critically. The use of the expotype for practical purposes requires proof of causality, and the added value of the expotype may be limited, for example if measured through the NNT (Number Needed to Treat). In addition, the medical system may not afford the extra budgets to measure the expotype at the patient's bed (particularly if it goes beyond the anamnesis and georeferencing, and includes omic measurements). I also argue that public health is largely a matter of structural interventions at the societal level, like taxation, and not only of individual responsibility. The main successes in tackling diseases have been tobacco taxation, sugar taxes and of course vaccination, rather than individualized health promotion. The proposal of extending precision therapy to precision prevention should not divert our attention from the great opportunities for prevention at the population level. Population prevention is cheaper, it usually addresses several diseases with a single intervention (think of smoking or air pollution) and does not need to be replicated at each generation like cure.</p>","PeriodicalId":73005,"journal":{"name":"Exposome","volume":"5 1","pages":"osaf011"},"PeriodicalIF":0.0,"publicationDate":"2025-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7618338/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145483570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Single-chemical analyses not only underestimate total health risk, but also ignore bias from multicollinearity and co-exposure confounding between chemicals. Advanced statistical mixture methods address these challenges and allow us to both estimate the cumulative health effect of chemical mixtures and identify the strongest chemical contributors. At the same time, untargeted chemical exposome profiling through high-resolution mass spectrometry (HRMS) now supports measurement of over 100,000 chemical signals in biospecimens. However, most mixture methods cannot evaluate untargeted exposome data containing more chemical variables than samples. Weighted quantile sum regression with its recent random subsets implementation (WQS_RS) is a unique, statistically powerful mixture method for high-dimensional exposome data. It estimates weights of chemicals towards the mixture index over many different repetitions in which only a small random subset of chemicals is used at a time, thus de-correlating data and avoiding overfitting. In this paper, we discuss our statistical workflow and important considerations for the application of WQS_RS to exposome epidemiology, including manual quantization for non-detects, custom repeated holdouts for matched data, pre-selection of exogenous chemicals, parameter decisions, interpretation options, and visualizations. We then describe its application to functional pathway enrichment analysis with integrated exposome-metabolome data to explore underlying biological mechanisms.
