Physiol."],"abstract":"<jats:sec><jats:title>Background<\/jats:title><jats:p>Stroke, a major global health concern, is responsible for high mortality and long-term disabilities. With the aging population and increasing prevalence of risk factors, its incidence is on the rise. Existing risk assessment tools have limitations, and there is a pressing need for more accurate and personalized stroke risk prediction models. Smoking, a significant modifiable risk factor, has not been comprehensively examined in current models regarding different smoking types.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Data were sourced from the 2015\u20132018 National Health and Nutrition Examination Survey (NHANES) and the 2020\u20132021 Behavioral Risk Factor Surveillance System (BRFSS). Tobacco use (including combustible cigarettes and e-cigarettes) and stroke history were obtained through questionnaires. Participants were divided into four subgroups: non-smokers, exclusive combustible cigarette users, exclusive e-cigarette users, and dual users. Covariates such as age, sex, race, education, and health conditions were also collected. Multivariate logistic regression was used to analyze the relationship between smoking and stroke. Four machine-learning models (XGBoost, logistic regression, Random Forest, and Gaussian Naive Bayes) were evaluated using the area under the receiver-operating characteristic curve (AUC), and Shapley\u2019s additive interpretation method was applied for feature importance ranking and model interpretation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 273,028 individuals were included in the study. Exclusive combustible cigarette users had an elevated stroke risk (\u03b2: 1.36, 95% CI: 1.26\u20131.47, <jats:italic>P<\/jats:italic> &amp;lt; 0.0001). Among the four machine-learning models, the XGBoost model showed the best discriminative ability with an AUC of 0.794 (95% CI = 0.787\u20130.802).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This study reveals a significant association between smoking types and stroke risk. An XGBoost-based stroke prediction model was established, which has the potential to improve the accuracy of stroke risk assessment and contribute to personalized interventions for stroke prevention, thus alleviating the healthcare burden related to stroke.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fphys.2025.1528910","type":"journal-article","created":{"date-parts":[[2025,3,24]],"date-time":"2025-03-24T08:58:00Z","timestamp":1742806680000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":7,"title":["Cross-sectional study on smoking types and stroke risk: development of a predictive model for identifying stroke risk"],"prefix":"10.3389","volume":"16","author":[{"given":"Chao","family":"Ding","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Minjia","family":"Yuan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiwei","family":"Cheng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Junkai","family":"Wen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,3,24]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"eadh3083","DOI":"10.1126\/sciadv.adh3083","article-title":"Mutational processes of tobacco smoking and APOBEC activity generate protein-truncating mutations in cancer genomes","volume":"9","author":"Adler","year":"2023","journal-title":"Sci.
