๐ Background
Stroke is a leading cause of morbidity and mortality worldwide, with a complex etiology that includes genetic, lifestyle, and environmental factors. Among these, phthalatesโubiquitous environmental chemicals used in various consumer productsโhave emerged as potential contributors to cerebrovascular health. Understanding their role in stroke risk is crucial for public health and preventive strategies.
๐๏ธ Study
This cross-sectional study utilized data from the National Health and Nutrition Examination Survey (NHANES) spanning from 2003 to 2018. Researchers analyzed the urinary phthalate metabolites of 10,771 adult participants, assessing their stroke status and various clinical covariates. The study employed advanced methodologies, including network toxicology, molecular docking, and machine learning techniques, to explore the associations between phthalate exposure and stroke risk.
๐ Results
The analysis revealed that higher concentrations of specific phthalates, namely MECPP, MCPP, MNBP, and MEOHP, were significantly correlated with an increased prevalence of stroke. The study also identified SRC as a critical target in the molecular pathways associated with stroke risk. Among the machine learning models tested, Random Forest achieved the highest predictive performance, with an AUC of 0.833. Additionally, moderate coffee consumption was linked to a reduced risk of stroke, suggesting a potential dietary intervention.
๐ Impact and Implications
The findings of this study underscore the importance of considering environmental chemicals like phthalates in stroke risk assessments. By identifying specific phthalates that may contribute to cerebrovascular health issues, public health initiatives can focus on reducing exposure. Furthermore, the potential protective effect of moderate coffee consumption opens avenues for dietary recommendations aimed at mitigating stroke risk. This research highlights the need for continued exploration of environmental factors in health outcomes.
๐ฎ Conclusion
This study provides valuable insights into the association between environmental chemicals and stroke risk, emphasizing the role of phthalates in cerebrovascular health. The identification of SRC as a key molecular target and the protective effect of moderate coffee consumption are significant findings that warrant further investigation. As we advance our understanding of these relationships, we can better inform public health strategies and individual choices to promote cardiovascular health.

Association Between Environmental Chemicals Phthalates and Stroke Among the US Adults: A Cross-Sectional Study.
Abstract
Stroke has a multifactorial etiology, and phthalates, as widely used environmental chemicals, may play an underexplored role in cerebrovascular health. This study aimed to evaluate the association between urinary phthalate metabolites and stroke risk using data from the National Health and Nutrition Examination Survey (NHANES), complemented by network toxicology, molecular docking, and machine learning approaches. We analyzed data from 10,771 adult participants in NHANES (2003-2018) who had complete records of stroke status, urinary phthalates, and clinical covariates. Multivariable logistic regression and restricted cubic spline (RCS) models were used to assess associations. We constructed protein-protein interaction networks and performed molecular docking to identify potential toxicological targets. Five machine learning algorithms were employed to develop predictive models for phthalate-related stroke risk. Higher levels of MECPP, MCPP, MNBP, and MEOHP were significantly associated with increased stroke prevalence. Network toxicology identified SRC as a key target, and molecular docking confirmed strong binding affinity between MBZP and SRC. Among the machine learning methods, Random Forest achieved the highest predictive performance (AUCโ=โ0.833). Notably, moderate coffee consumption (โคโ170ย g/day) was significantly associated with a reduced risk of stroke (ORโ=โ0.63, 95%CI: 0.51-0.77), suggesting potential dietary mitigation against phthalate-related stroke risk. Our findings demonstrate that certain phthalates may increase stroke risk via molecular pathways involving SRC. Furthermore, moderate coffee consumption may mitigate the adverse cerebrovascular effects of these environmental pollutants.
