Healthcare utilisation, induced labour and caesarean section in the pregnancy after stillbirth: a prospective study

Abstract

Objective To investigate healthcare utilisation, induced labour and caesarean section (CS) in the pregnancy after stillbirth and assess anxiety and dread of childbirth as mediators for these outcomes. Design Population-based pregnancy cohort study. Setting The Norwegian Mother and Child Cohort Study. Sample 901 pregnant women; 174 pregnant after stillbirth, 362 pregnant after live birth and 365 previously nulliparous. Methods Data from questionnaires answered in the second and third trimesters of pregnancy and information from the Medical Birth Registry of Norway. Main outcome measures Self-reported assessment of antenatal care, register-based assessment of onset and mode of delivery. Results Women with a previous stillbirth had more frequent antenatal visits (mean 10.0; 95% confidence interval [CI] 9.4 - 10.7) compared with women with a previous live birth (6.0; 5.8 - 6.2) and previously nulliparous women (6.3; 6.1 - 6.6). Induced labour and CS, elective and emergency, were also more prevalent in the stillbirth group. The adjusted odds ratio for elective CS was 2.5 (95% CI 1.3 – 5.0) compared with women with previous live birth and 3.7 (1.8 - 7.6) compared with previously nulliparous women. Anxiety was a minor mediator for the association between stillbirth and frequency of antenatal visits, while dread of childbirth was not a significant mediator for elective CS. Conclusions Women pregnant after stillbirth were more ample users of healthcare services and had more often induced labour and CS. The higher frequency of antenatal visits and elective CS could not be accounted for by anxiety or dread of childbirth.
