This analysis aimed to prospectively determine  the incidence of preeclampsia in a cohort of pregnant women in Switzerland.\n        METHODS: Pregnant  women presenting at gestational week 11\u201314 at their obstetrician\u2019s office were  consecutively included and prospectively followed-up until the end of  pregnancy. Ultrasound characteristics, blood pressure measurements, body mass  index, and personal history were recorded. Duration of pregnancy, occurrence of  preeclampsia, birth weight and Apgar scores were recorded as outcomes.\n        RESULTS: There  were 1,300 pregnancies with follow-up available for analysis. Median age was 30  years (interquartile range [IQR] 27\u201333), median body mass index (BMI) 23.3 kg\/m2 (IQR 21.2\u201326.1), median systolic blood pressure 117 mm Hg (IQR 109\u2013126) and  median diastolic blood pressure 70 mm Hg (IQR 64\u201377). A total of 30 women  developed preeclampsia, corresponding to an incidence of 2.31% (95% confidence  interval [CI] 1.62%\u20133.28%). Of the women with preeclampsia, 6.66% (95% CI 2.04%\u201321.42%)  had early-onset preeclampsia, 13.33% (95% CI 5.45%\u201329.83%) progressed to  eclampsia, whereas 10% (95% CI 3.63%\u201328.75%) developed HELLP syndrome  (haemolysis, elevated liver enzymes, low platelet count). Nulliparity and prior  history of preeclampsia were more frequently seen in pregnancies with preeclampsia  than in pregnancies without preeclampsia. BMI, as well as systolic and  diastolic blood pressure were higher in pregnancies subsequently developing preeclampsia.\n        CONCLUSION:  The incidence of preeclampsia in Switzerland is in line with frequencies  observed elsewhere in the world. Extrapolation to a national level indicates  that about 1,911 (range 1,340\u20132,713) preeclampsia cases per year can be expected  to occur in Switzerland.<\/jats:p>","DOI":"10.4414\/smw.2015.14175","type":"journal-article","created":{"date-parts":[[2016,1,29]],"date-time":"2016-01-29T10:03:57Z","timestamp":1454061837000},"page":"w14175","source":"Crossref","is-referenced-by-count":17,"title":["Incidence  of preeclampsia in pregnant Swiss\u00a0women"],"prefix":"10.57187","volume":"145","author":[{"given":"Mette-Triin","family":"Purde","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marc","family":"Baumann","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ute","family":"Wiedemann","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Urs","family":"Nydegger","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lorenz","family":"Risch","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Surbek","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin","family":"Risch","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"36756","published-online":{"date-parts":[[2015,7,26]]},"container-title":["Swiss Medical Weekly"],"original-title":[],"link":[{"URL":"https:\/\/smw.ch\/index.php\/smw\/article\/download\/2057\/2992","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/smw.ch\/index.php\/smw\/article\/download\/2057\/2993","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/smw.ch\/index.php\/smw\/article\/download\/2057\/2992","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,15]],"date-time":"2025-08-15T06:32:25Z","timestamp":1755239545000},"score":1,"resource":{"primary":{"URL":"https:\/\/smw.ch\/index.php\/smw\/article\/view\/2057"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,7,26]]},"references-count":0,"journal-issue":{"issue":"3132","published-online":{"date-parts":[[2015,7,27]]}},"URL":"https:\/\/doi.org\/10.4414\/smw.2015.14175","relation":{},"ISSN":["1424-3997"],"issn-type":[{"value":"1424-3997","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,7,26]]}}}
