Besides having high co\u2010occurrence and interrelation, it is suggested that these outcomes, along with preeclampsia, are associated with reduced subsequent fertility. On the other hand, the loss of a child during the perinatal period is associated with increased reproduction. Failure to consider this factor when estimating the effects of pregnancy outcomes on future reproduction may lead to erroneous conclusions. However, few studies have explored to what degree a perinatal loss contributes to having a next pregnancy in various adverse pregnancy outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Material and methods<\/jats:title>\n                    <jats:p>This was a population\u2010based study of mothers giving birth to their first singleton infant (\u226522 gestational weeks) during 1967\u20102007 who were followed for the occurrence of a second birth in the Medical Birth Registry of Norway until 2014. Relative risks with 95% confidence intervals for having one lifetime pregnancy by preterm delivery, small\u2010for\u2010gestational\u2010age, preeclampsia and cesarean section were obtained by generalized linear models for the binary family and adjusted for maternal age at first birth, education and year of first childbirth. Main outcome measure was having one lifetime pregnancy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Nearly 900\u00a0000 women gave birth to their first singleton infant in 1967\u20102007, of which 16% had only one lifetime pregnancy. These women were older at first delivery, had less education and there was a higher proportion of unmarried women than women with two or more births. In women with pregnancy complications where the infant survived the perinatal period, there were the following relative risks for one lifetime pregnancy: increased preterm delivery: 1.21 (1.19\u20101.22)], small\u2010for\u2010gestational\u2010age: 1.13 (1.12\u20101.15), preeclampsia: 1.09 (1.07\u20101.11), cesarean section: 1.24 (1.23\u20101.25). The risk was significantly reduced if the child was lost (preterm delivery: 0.63 [0.59\u20100.68], small\u2010for\u2010gestational\u2010age: 0.57 [0.51\u20100.63], preeclampsia: 0.69 [0.59\u20100.80], cesarean section: 0.67 [0.56\u20100.79]), compared with women with no perinatal loss and no adverse outcome.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The associations between adverse outcomes of pregnancy and the risk of having one lifetime pregnancy were strongly modified by child survival in the perinatal period.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/aogs.13534","type":"journal-article","created":{"date-parts":[[2019,1,16]],"date-time":"2019-01-16T05:05:16Z","timestamp":1547615116000},"page":"753-760","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Risk of having one lifetime pregnancy and modification by outcome of pregnancy and perinatal loss"],"prefix":"10.1111","volume":"98","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5084-9171","authenticated-orcid":false,"given":"Aleksandra","family":"Pirnat","sequence":"first","affiliation":[{"name":"Department of Global Public Health and Primary Care University of Bergen Bergen Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lisa A.","family":"DeRoo","sequence":"additional","affiliation":[{"name":"Department of Global Public Health and Primary Care University of Bergen Bergen Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6126-8655","authenticated-orcid":false,"given":"Rolv","family":"Skj\u00e6rven","sequence":"additional","affiliation":[{"name":"Department of Global Public Health and Primary Care University of Bergen Bergen Norway"},{"name":"Fertility Center Norwegian Institute of Public Health Bergen Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nils\u2010Halvdan","family":"Morken","sequence":"additional","affiliation":[{"name":"Department of Clinical Science University of Bergen Bergen Norway"},{"name":"Department of Obstetrics and Gynecology Haukeland University Hospital Bergen Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2019,2,3]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.3109\/14767058.2011.553695"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1177\/2047487315571891"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.AOG.0000292089.18717.9f"},{"key":"e_1_2_10_5_1","doi-asserted-by":"crossref","first-page":"e012894","DOI":"10.1136\/bmjopen-2016-012894","article-title":"Long\u2010term mortality in mothers with perinatal losses and risk modification by surviving children and attained education: a population\u2010based cohort study","volume":"24","author":"Halland F","year":"2016","journal-title":"BMJ Open"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1093\/aje\/kwm319"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/1471-0528.14906"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0015-0282(16)48491-8"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9378(87)80177-1"},{"key":"e_1_2_10_10_1","first-page":"175","article-title":"Selective fertility\u2014the examples of perinatal death and preeclampsia","volume":"17","author":"Skjaerven R","year":"2007","journal-title":"Norsk Epidemiol"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1093\/oxfordjournals.aje.a115088"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-0412.2000.079006435.x"},{"key":"e_1_2_10_13_1","doi-asserted-by":"crossref","first-page":"450","DOI":"10.1034\/j.1600-0412.2000.079006440.x","article-title":"Birthweight by gestational age in Norway","volume":"79","author":"Skjaerven R","year":"2000","journal-title":"Acta Obstet Gynecol Scand"},{"key":"e_1_2_10_14_1","unstructured":"StaffA AndersgaardAB HenriksenT et\u00a0al.Hypertensive svangerskapskomplikasjoner og eklampsi.
