Cases were derived from a population\u2010based birth defects registry in Hawaii and comprised all infants and fetuses with hemivertebrae delivered during 1986\u20132002. Hemivertebrae rates per 10\u2003000 births were determined for selected factors and comparisons made by calculating the rate ratio (RR) and 95% confidence interval (CI). Forty\u2010two cases of hemivertebrae were identified, for a total rate of 1.33. Forty\u2010one of the cases were live births, of which 26.83% expired within one year after delivery. Other major structural birth defects were found in 95.24% of the cases. The most frequent associated defect was scoliosis, affecting 54.76% of the cases. The rate among females was significantly lower than among males (RR 0.48, 95% CI 0.23\u20130.94). The rate was lower with maternal age \u226535\u2003years (RR 0.50, 95% CI 0.10\u20131.57) and higher with birth weight &lt;2500\u2003g (RR 5.96, 95% CI 2.84\u201311.90) and gestational age &lt;38\u2003weeks (RR 3.94, 95% CI 2.01\u20137.64). The majority of hemivertebrae cases had other major structural birth defects. Hemivertebrae occurred predominantly among males and risk was lower with increased maternal age. Rates for hemivertebrae were higher with lower birth weight and gestational age. Further population\u2010based research involving larger study populations are recommended to confirm these observations.\n                  <\/jats:p>","DOI":"10.1111\/j.1741-4520.2006.00124.x","type":"journal-article","created":{"date-parts":[[2006,11,9]],"date-time":"2006-11-09T05:21:19Z","timestamp":1163049679000},"page":"172-176","source":"Crossref","is-referenced-by-count":14,"title":["Descriptive epidemiology of hemivertebrae, Hawaii, 1986\u20132002"],"prefix":"10.1111","volume":"46","author":[{"given":"Mathias B.","family":"Forrester","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruth D.","family":"Merz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2006,11,9]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(00)02756-2"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.1320270220"},{"key":"e_1_2_6_4_1","volume-title":"Genetic and Environmental Risk Factors of Major Cardiovascular Malformations: The Baltimore\u2010Washington Infant Study: 1981\u20131989","author":"Ferencz C","year":"1997"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00211434"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.2307\/3431737"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1159\/000082435"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/s132-002-8272-y"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0033-3549(04)50054-7"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1651-2227.1982.tb09577.x"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1002\/tera.1070"},{"issue":"2","key":"e_1_2_6_12_1","first-page":"84","article-title":"Effects of exposure to environmental tobacco smoke on reproductive health","volume":"28","author":"Lindbohm ML","year":"2002","journal-title":"Scand J Work Environ Health"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajog.2005.02.096"},{"key":"e_1_2_6_14_1","doi-asserted-by":"crossref","first-page":"588","DOI":"10.1302\/0301-620X.68B4.3733836","article-title":"Hemivertebra as a cause of scoliosis","volume":"68","author":"McMaster MJ","year":"1986","journal-title":"J Bone Joint Surg Br"},{"key":"e_1_2_6_15_1","doi-asserted-by":"publisher","DOI":"10.1002\/tera.1420420311"},{"key":"e_1_2_6_16_1","doi-asserted-by":"publisher","DOI":"10.1002\/bdra.20071"},{"key":"e_1_2_6_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0301-2115(01)00347-5"},{"key":"e_1_2_6_18_1","doi-asserted-by":"publisher","DOI":"10.1002\/bdra.20068"},{"key":"e_1_2_6_19_1","doi-asserted-by":"publisher","DOI":"10.3109\/17453678109050122"},{"key":"e_1_2_6_20_1","doi-asserted-by":"publisher","DOI":"10.1067\/mpd.2002.128891"},{"key":"e_1_2_6_21_1","doi-asserted-by":"publisher","DOI":"10.1136\/jmg.12.3.280"},{"key":"e_1_2_6_22_1","first-page":"412","article-title":"Fetal hemivertebrae: Associated anomalies, significance, and outcome","volume":"81","author":"Zelop CM","year":"1993","journal-title":"Obstet Gynecol"}],"container-title":["Congenital Anomalies"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fj.1741-4520.2006.00124.x","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/j.1741-4520.2006.00124.x","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,11]],"date-time":"2023-10-11T01:08:26Z","timestamp":1696986506000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/j.1741-4520.2006.00124.x"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2006,11,9]]},"references-count":21,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2006,12]]}},"alternative-id":["10.1111\/j.1741-4520.2006.00124.x"],"URL":"https:\/\/doi.org\/10.1111\/j.1741-4520.2006.00124.x","archive":["Portico"],"relation":{},"ISSN":["0914-3505","1741-4520"],"issn-type":[{"value":"0914-3505","type":"print"},{"value":"1741-4520","type":"electronic"}],"subject":[],"published":{"date-parts":[[2006,11,9]]}}}
