Outcomes included total stroke, ischemic stroke, and hemorrhagic stroke, identified through hospital records. Cox regression models adjusted for demographic, behavioral, and clinical covariates were used to estimate hazard ratios (HRs) and 95 % confidence intervals (CIs).</div></div><div><h3>Results</h3><div>Over a median follow-up of 11.8 years, 5,051 participants experienced strokes. SHS exposure >4 hours/week was associated with increased incident stroke risk (HR 1.34, 95 % CI 1.18–1.52) compared to no exposure. Maternal smoking was associated with a 7 % increase in total stroke risk (HR 1.07, 95 % CI 1.02–1.14). Combined exposure to SHS >4 hours/week and maternal smoking conferred the highest stroke risk (HR 1.57, 95 % CI 1.29–1.90). Subgroup and sensitivity analyses confirmed these findings.</div></div><div><h3>Conclusions</h3><div>SHS exposure and maternal smoking was independently and jointly associated with higher stroke risk, underscoring the need for robust tobacco control policies to mitigate these exposures and their public health impact.</div></div>","PeriodicalId":54368,"journal":{"name":"Journal of Stroke & Cerebrovascular Diseases","volume":"34 8","pages":"Article 108379"},"PeriodicalIF":2.0,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144328461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
