We conducted a population\u2010based, case\u2014control study in Washington State using 1994 to 2002 linked data from the Washington State Birth Registry and the Comprehensive Hospital Abstract Reporting System (CHARS). We identified 1060 singleton, term newborns (602 males, 458 females) with International Classification of Diseases (ICD\u20109) diagnoses consistent with encephalopathy, and 5330 unaffected control newborns (2756 males, 2574 females). Intrapartum fever was defined by a diagnosis of intrapartum temperature of &gt;38\u00b0C in the birth registry or CHARS databases. Chorioamnionitis was defined using ICD\u20109 diagnoses recorded in CHARS. We identified 2.2 cases of encephalopathy per 1000 births. Isolated intrapartum fever was associated with a 3.1\u2010fold (95% confidence interval [CI] 2.3\u20104.2) increased risk of newborn encephalopathy. Chorioamnionitis was associated with a 5.4\u2010fold (95% CI 3.6\u20107.8) increased risk of encephalopathy. We found that isolated intrapartum fever and chorioamnionitis were independently associated with an increased risk of encephalopathy in term infants. Our data also indicate that there is a spectrum of risk for encephalopathy in term infants exposed to intrapartum fever. Infants born to women with signs of chorioamnionitis other than isolated intrapartum fever may be at higher risk of encephalopathy than those exposed only to isolated intrapartum fever.<\/jats:p>","DOI":"10.1111\/j.1469-8749.2007.02007.x","type":"journal-article","created":{"date-parts":[[2009,6,23]],"date-time":"2009-06-23T07:44:36Z","timestamp":1245743076000},"page":"19-24","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":91,"title":["Intrapartum fever and chorioamnionitis as risks for encephalopathy in term newborns: a case\u2013control study"],"prefix":"10.1111","volume":"50","author":[{"given":"Heidi K","family":"Blume","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher I","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christian M","family":"Loch","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas D","family":"Koepsell","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2007,11,28]]},"reference":[{"key":"e_1_2_2_2_2","first-page":"1325","article-title":"How much of neonatal encephalopathy is due to birth asphyxia","volume":"145","author":"Nelson KB","year":"1991","journal-title":"Am J Dis Child"},{"key":"e_1_2_2_3_2","volume-title":"Neonatal Encephalopathy and Cerebral Palsy: Defining the Pathogenesis and Pathophysiology.","author":"American College of Obstetricians and Gynecologists\/American Academy of Pediatrics.","year":"2003"},{"key":"e_1_2_2_4_2","volume-title":"Neurology Of The Newborn.","author":"Volpe J","year":"2001"},{"key":"e_1_2_2_5_2","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.317.7172.1554"},{"key":"e_1_2_2_6_2","doi-asserted-by":"crossref","first-page":"780","DOI":"10.1097\/01.AOG.0000120142.83093.30","article-title":"Neonatal encephalopathy and cerebral palsy: executive summary","volume":"103","author":"American College of Obstetricians and Gynecologists.","year":"2004","journal-title":"Obstet Gynecol"},{"key":"e_1_2_2_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3476(81)80555-0"},{"key":"e_1_2_2_8_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1440-1754.2004.00341.x"},{"key":"e_1_2_2_9_2","doi-asserted-by":"publisher","DOI":"10.1542\/peds.109.1.26"},{"key":"e_1_2_2_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0095-5108(18)30405-6"},{"key":"e_1_2_2_11_2","doi-asserted-by":"publisher","DOI":"10.1136\/fn.86.1.F16"},{"key":"e_1_2_2_12_2","doi-asserted-by":"publisher","DOI":"10.1136\/adc.2004.067520"},{"key":"e_1_2_2_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0095-5108(02)00058-1"},{"key":"e_1_2_2_14_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM198810133191503"},{"key":"e_1_2_2_15_2","doi-asserted-by":"publisher","DOI":"10.1001\/jama.290.20.2677"},{"key":"e_1_2_2_16_2","doi-asserted-by":"publisher","DOI":"10.1007\/PL00008403"},{"key":"e_1_2_2_17_2","doi-asserted-by":"publisher","DOI":"10.1001\/jama.1997.03550030047032"},{"key":"e_1_2_2_18_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0029-7844(01)01361-8"},{"key":"e_1_2_2_19_2","doi-asserted-by":"publisher","DOI":"10.1542\/peds.106.5.983"},{"key":"e_1_2_2_20_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1471-0528.2001.00145.x"},{"key":"e_1_2_2_21_2","volume-title":"International Classification of Diseases.","author":"World Health Organization","year":"1977"},{"key":"e_1_2_2_22_2","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.317.7172.1549"},{"key":"e_1_2_2_23_2","doi-asserted-by":"publisher","DOI":"10.1080\/01443610020025967"},{"key":"e_1_2_2_24_2","volume-title":"Epidemiologic Methods: Studying the Occurrence of Illness.","author":"Koepsell T","year":"2003"},{"key":"e_1_2_2_25_2","doi-asserted-by":"publisher","DOI":"10.1093\/oxfordjournals.aje.a116813"},{"key":"e_1_2_2_26_2","doi-asserted-by":"publisher","DOI":"10.1001\/archpedi.161.7.663"},{"key":"e_1_2_2_27_2","doi-asserted-by":"publisher","DOI":"10.1136\/adc.2003.047985"}],"container-title":["Developmental Medicine &amp;
