Records from affiliated maternity centres and the hospital regarding these 261 women were studied and pertinent data assembled for comparison with 260 matched normotensive pregnancies. Instrumental deliveries were more common in all types of hypertensive pregnancy, with a 35% freqeuncy of caesarean section in severe pre\u2010eclampsia compared with fewer than 5% for controls. Significantly longer hospitalization and increased perinatal mortality were observed in hypertensive pregnancies, most pronounced in severe pre\u2010eclampsia. The combination of high blood pressure and proteinuria was associated with the greatest risk for premature birth, low infant weight and perinatal mortality. The overall incidence of hypertensive disorders in pregnancy was relatively low, 1.5%, but these women counted for a significant proportion of obstetric complications requiring hospitalization and instrumental delivery.<\/jats:p>","DOI":"10.3109\/00016348409157120","type":"journal-article","created":{"date-parts":[[2009,12,8]],"date-time":"2009-12-08T17:58:25Z","timestamp":1260295105000},"page":"33-38","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Characteristics of Hypertension in Pregnancy"],"prefix":"10.1111","volume":"63","author":[{"given":"Bj\u00f6m","family":"Andersch","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anders","family":"Svensson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lennart","family":"Hansson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2011,1,11]]},"reference":[{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.3109\/03009737809179108"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1038\/ki.1980.131"},{"key":"e_1_2_1_4_1","unstructured":"Enh\u00f6rningG..1983 Personal communication."},{"key":"e_1_2_1_5_1","first-page":"225","article-title":"Health control of women with arterial hypertension during earlier pregnancy","volume":"73","author":"Frithiof J.","year":"1976","journal-title":"LBkartidn"},{"key":"e_1_2_1_6_1","volume-title":"Concepts and Management","author":"Gant N.
