The aim of this study was to examine the associations of gaseous air pollution with stroke admissions in Beijing, 2013\u20132014 in different subgroups. Methods: Case-crossover design and conditional logistic regression were used to perform the analyses. We examined the exposure-response relationship between air pollution and stroke. Stratified analyses were performed in different seasons, sex, and age groups. Results: There were 147,624 stroke admissions during the study period. In the whole study period, percent changes of stroke admissions were 0.82% (95% CI: 0.52% to 1.13%) and 0.73% (95% CI: 0.44% to 1.03%) per 10 \u03bcg\/m3 increase in the same day conentration of nitrogen dioxide (NO2) and sulfur dioxide (SO2). The positive associations were higher in warm seasons and with patients &gt;65 years (p &lt; 0.05). Contrary effects of carbon monoxide (CO) and ozone on stroke admissions were observed in different seasons. Conclusions: NO2 and SO2 were positively associated with stroke admissions, with stronger effects in warm seasons and with patients &gt;65 years. The associations of CO and ozone with stroke admissions differed across seasons.<\/jats:p>","DOI":"10.3390\/ijerph14020189","type":"journal-article","created":{"date-parts":[[2017,2,15]],"date-time":"2017-02-15T10:09:07Z","timestamp":1487153347000},"page":"189","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":35,"title":["Gaseous Air Pollution and the Risk for Stroke Admissions: A Case-Crossover Study in Beijing, China"],"prefix":"10.3390","volume":"14","author":[{"given":"Fangfang","family":"Huang","sequence":"first","affiliation":[{"name":"School of Public Health, Capital Medical University, Beijing 100069, China"},{"name":"Beijing Municipal Key Laboratory of Clinical Epidemiology, Beijing 100069, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanxia","family":"Luo","sequence":"additional","affiliation":[{"name":"School of Public Health, Capital Medical University, Beijing 100069, China"},{"name":"Beijing Municipal Key Laboratory of Clinical Epidemiology, Beijing 100069, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peng","family":"Tan","sequence":"additional","affiliation":[{"name":"Beijing Public Health Information Center, Beijing 100050, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qin","family":"Xu","sequence":"additional","affiliation":[{"name":"School of Public Health, Capital Medical University, Beijing 100069, China"},{"name":"Beijing Municipal Key Laboratory of Clinical Epidemiology, Beijing 100069, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lixin","family":"Tao","sequence":"additional","affiliation":[{"name":"School of Public Health, Capital Medical University, Beijing 100069, China"},{"name":"Beijing Municipal Key Laboratory of Clinical Epidemiology, Beijing 100069, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jin","family":"Guo","sequence":"additional","affiliation":[{"name":"School of Public Health, Capital Medical University, Beijing 100069, China"},{"name":"Beijing Municipal Key Laboratory of Clinical Epidemiology, Beijing 100069, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Feng","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Public Health, Capital Medical University, Beijing 100069, China"},{"name":"Beijing Municipal Key Laboratory of Clinical Epidemiology, Beijing 100069, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xueqin","family":"Xie","sequence":"additional","affiliation":[{"name":"Beijing Public Health Information Center, Beijing 100050, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6657-6940","authenticated-orcid":false,"given":"Xiuhua","family":"Guo","sequence":"additional","affiliation":[{"name":"School of Public Health, Capital Medical University, Beijing 100069, China"},{"name":"Beijing Municipal Key Laboratory of Clinical Epidemiology, Beijing 100069, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2017,2,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"79","DOI":"10.1021\/acs.est.5b03709","article-title":"Ambient air pollution exposure estimation for the Global Burden of Disease 2013","volume":"50","author":"Brauer","year":"2016","journal-title":"Environ.
