During 5.533 million person-years of follow-up (mean 17 years), 8678 offspring had an incident stroke or TIA (5.2% of the 24\u2009583 offspring with a parental history of AF compared with 2.5% of the 300\u2009750 offspring with no parental history of AF), and 1430 were diagnosed with AF (1.9% versus 0.3%). Incidence rates for stroke\/TIA were higher in offspring with a parental history of AF (195.0 versus 156.6 per 100\u2009000 person-years). Parental AF was associated with elevated risk in offspring of stroke\/TIA (hazard ratio 1.11; 95% CI, 1.04\u20131.18) or AF (hazard ratio 1.75; 95% CI, 1.55\u20131.97) and a higher frequency of other cardiovascular risk factors. After adjusting for demographics, region of residence, socioeconomic status, and other stroke risk factors in offspring, parental AF was associated with AF in their offspring in young adulthood (adjusted hazard ratio 1.61; 95% CI, 1.43\u20131.82); the association of parental AF with offspring stroke\/TIA was attenuated (adjusted hazard ratio 1.05; 95% CI, 0.99\u20131.12) after adjusting for the other cardiovascular risk factors.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions\u2014<\/jats:title>\n            <jats:p>Parental AF is associated with increased risk of AF and other cardiovascular risk factors in their offspring during early adulthood, resulting in increased stroke risk.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1161\/strokeaha.119.025124","type":"journal-article","created":{"date-parts":[[2019,7,24]],"date-time":"2019-07-24T10:51:05Z","timestamp":1563965465000},"page":"2322-2328","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":9,"title":["Parental Atrial Fibrillation and Stroke or Atrial Fibrillation in Young Adults"],"prefix":"10.1161","volume":"50","author":[{"given":"Finlay A.","family":"McAlister","sequence":"first","affiliation":[{"name":"From the Division of General Internal Medicine, University of Alberta, Edmonton, Canada (F.A.M.)"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lin","family":"Yan","sequence":"additional","affiliation":[{"name":"Department of Community Health Sciences, University of Manitoba, Winnipeg, Manitoba, Canada (L.Y., L.L.R., L.M.L.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leslie L.","family":"Roos","sequence":"additional","affiliation":[{"name":"Department of Community Health Sciences, University of Manitoba, Winnipeg, Manitoba, Canada (L.Y., L.L.R., L.M.L.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lisa M.","family":"Lix","sequence":"additional","affiliation":[{"name":"Department of Community Health Sciences, University of Manitoba, Winnipeg, Manitoba, Canada (L.Y., L.L.R., L.M.L.)."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa1311376"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa1105575"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2012.03.046"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ahj.2016.01.020"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1001\/jama.291.23.2851"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2010.1690"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.1001\/jamacardio.2017.1855"},{"key":"e_1_3_3_9_2","doi-asserted-by":"publisher","DOI":"10.1002\/jbmr.2849"},{"key":"e_1_3_3_10_2","doi-asserted-by":"publisher","DOI":"10.1002\/pds.2317"},{"key":"e_1_3_3_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cjca.2016.06.006"},{"key":"e_1_3_3_12_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.0000174293.17959.a1"},{"key":"e_1_3_3_13_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0135834"},{"key":"e_1_3_3_14_2","doi-asserted-by":"publisher","DOI":"10.1001\/jama.285.22.2864"},{"key":"e_1_3_3_15_2","doi-asserted-by":"publisher","DOI":"10.1378\/chest.09-1584"},{"key":"e_1_3_3_16_2","unstructured":"Manitoba Centre for Health Policy.
