Objectives: To investigate the risk of stillbirth in relation to (1) a previous caesarean delivery (CD) compared with those following a vaginal birth (VB); and (2) vaginal birth after caesarean (VBAC) compared with a repeat CD. Design: Population‐based cohort study. Setting: The Swedish Medical Birth registry. Population: Women with their first and second singletons between 1982 and 2012. Methods: Multivariable logistic regression models were performed to estimate adjusted odds ratios (aOR) and 95% confidence intervals (CI) of the association between CD in the first pregnancy and stillbirth in the second pregnancy and the association between VBAC and stillbirth. Sub‐group analyses were performed by types of CD and timing of stillbirth (antepartum and intrapartum). Main outcome measures: Stillbirth (antepartum and intrapartum fetal death). Results: Of the 1 771 700 singleton births from 885 850 women, 117 114 (13.2%) women had a CD in the first pregnancy, and 51 755 had VBAC in the second pregnancy. We found a 37% increased odds of stillbirth (aOR 1.37; 95% CI 1.23–1.52) in women with a previous CD compared with VB. The odds of intrapartum stillbirth were higher in the previous pre‐labour CD group (aOR 2.72; 95% CI 1.51–4.91) and in the previous in‐labour CD group (aOR 1.35; 95% CI 0.76–2.40), although not statistically significant in the latter case. No increased odds were found for intrapartum stillbirth in women who had VBAC (aOR 0.99; 95% CI 0.48–2.06) compared with women who had a repeat CD. Conclusions: This study confirms that a CD is associated with an increased risk of subsequent stillbirth, with a greater risk among pre‐labour CD. This association is not solely mediated by increases in intrapartum asphyxia, uterine rupture or attempted VBAC. Further research is needed to understand this association, but these findings might help healthcare providers to reach optimal decisions regarding mode of birth, particularly when CD is unnecessary.

Introduction: Our study evaluated how a history of stillbirth in either of the first two pregnancies affects the risk of having a stillbirth or other adverse pregnancy outcomes in the third subsequent pregnancy. Material and Methods: We used the Swedish Medical Birth Register to define a population‐based cohort of women who had at least three singleton births from 1973 to 2012. The exposure of interest was a history of stillbirth in either of the first two pregnancies. The primary outcome was subsequent stillbirth in the third pregnancy. Secondary outcomes included: preterm birth, preeclampsia, placental abruption and small‐for‐gestational‐age infant. Adjusted logistic regression was performed including maternal age, body mass index, smoking, diabetes and hypertension. A sensitivity analysis was performed excluding stillbirths associated with congenital anomalies, pregestational and gestational diabetes, hypertension and preterm stillbirths. Results: The study contained data on 1 316 175 births, including 8911 stillbirths. Compared with women who had two live births, the highest odds of stillbirth in the third pregnancy were observed in women who had two stillbirths (adjusted odds ratio [aOR] 11.40, 95% confidence interval [95% CI] 2.75–47.70), followed by those who had stillbirth in the second birth (live birth–stillbirth) (aOR 3.59, 95% CI 2.58–4.98), but the odds were still elevated in those whose first birth ended in stillbirth (stillbirth–live birth) (aOR 2.35, 1.68, 3.28). Preterm birth, pre‐eclampsia and placental abruption followed a similar pattern. The odds of having a small‐for‐gestational‐age infant were highest in women whose first birth ended in stillbirth (aOR 1.93, 95% CI 1.66–2.24). The increased odds of having a stillbirth in a third pregnancy when either of the earlier births ended in stillbirth remained when stillbirths associated with congenital anomalies, pregestational and gestational diabetes, hypertension or preterm stillbirths were excluded. However, when preterm stillbirths were excluded, the strength of the association was reduced. Conclusions: Even when they have had a live‐born infant, women with a history of stillbirth have an increased risk of adverse pregnancy outcomes; this cannot be solely accounted for by the recurrence of congenital anomalies or maternal medical disorders. This suggests that women with a history of stillbirth should be offered additional surveillance for subsequent pregnancies. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Improved Pregnancy Outcomes via Early Detection (IMPROvED) is a multi-centre, European phase IIa clinical study. The primary aim of IMPROvED is to enable the assessment and refinement of innovative prototype preeclampsia risk assessment tests based on emerging biomarker technologies. Here we describe IMPROvED's profile and invite researchers to collaborate., Methods: A total of 4,038 low-risk nulliparous singleton pregnancies were recruited from maternity units in Ireland (N=1,501), United Kingdom (N=1,108), The Netherlands (N=810), and Sweden (N=619) between November 2013 to August 2017. Participants were interviewed by a research midwife at ~11 weeks (optional visit), ~15 weeks, ~20 weeks, ~34 weeks' gestation (optional visit), and postpartum (within 72-hours following delivery)., Findings to Date: Clinical data included information on maternal sociodemographic, medical history, and lifestyle factors collected at ~15 weeks' gestation, and maternal measurements, collected at each study visit. Biobank samples included blood, urine, and hair collected at each study visit throughout pregnancy in all units plus umbilical cord/blood samples collected at birth in Ireland and Sweden. A total of 74.0% (N=2,922) had an uncomplicated pregnancy, 3.1% (N=122) developed preeclampsia, 3.6% (N=143) had a spontaneous preterm birth, and 10.5% (N=416) had a small for gestational age baby. We evaluated a panel of metabolite biomarkers and a panel of protein biomarkers at 15 weeks and 20 weeks' gestation for preeclampsia risk assessment. Their translation into tests with clinical application, as conducted by commercial entities, was hampered by technical issues and changes in test requirements. Work on the panel of proteins was abandoned, while work on the use of metabolite biomarkers for preeclampsia risk assessment is ongoing., Future Plans: In accordance with the original goals of the IMPROvED study, the data and biobank are now available for international collaboration to conduct high quality research into the cause and prevention of adverse pregnancy outcomes., Competing Interests: Competing interests: RT is an employee of Metabolomic Diagnostics. RT is a named inventor on several patent applications regarding the use of biomarkers to predict preeclampsia risk; the associated rights are assigned to Metabolomic Diagnostics. PNB and LCK are minority shareholders in Metabolomic Diagnostics, which seeks to develop predictive tests for major pregnancy complications.
