Objective Intimate partner violence is a global health concern with a wide range of consequences. This article aims to assess the association between intimate partner violence among pregnant women and register-based psychiatric diagnoses, taking risk factors and non-responders into account. Design A cross-sectional study utilising Danish registers Setting Denmark Population 28,697 pregnant women Methods Pregnant women attending antenatal care in the Region of Southern Denmark, or the Capital Region, took part in the routinely collected PROdata questionnaire containing the Abuse Assessment Screen(AAS) during their first trimester, from December 2019 to September 2022. After questionnaire collection, data was linked with multiple Danish registers, including the Danish Psychiatric Treatment Register. On an individual level, the psychiatric diagnoses were detected in the registers, and if the woman had a psychiatric diagnosis within the last five years, she was grouped as either moderate or severe psychiatric diagnoses. Main Outcome Measures Moderate or severe psychiatric diagnoses Results In total, 28,697 women received the PROdata questionnaire, and 23,768 (82,8%) responded to the AAS. The prevalence of screening positive for IPV was 5.34% (n=1269). We found a strong association between intimate partner violence and both moderate and severe psychiatric diagnoses with an increased adjusted OR of 3.01 (95% CI: 2.51, 3.60) and 4.34 (95% CI: 3.27, 5.85), respectively, compared with women with no psychiatric diagnoses. Conclusion Our results show a strong link between Intimate Partner Violence and psychiatric diagnoses among pregnant women. It also provides important information on risk factors for violence and characteristics of non-responders to digital screening.

Objective: To develop a prediction model for labour dystocia, suitable for risk stratification at onset of labour. Design: A cohort-based registry design was employed using data from the Copenhagen Pregnancy Cohort and the Danish Medical Birth Registry. Setting: The study was conducted at Copenhagen University Hospital – Rigshospitalet, Denmark Population: Nulliparous women with a singleton pregnancy and cephalic presentation in spontaneous labour at term from 2014 to 2020. Methods: Logistic regression analysis was employed to construct the prediction model. Candidate predictors were pre-selected based on clinical reasoning and existing evidence. These were maternal age, pre-pregnancy body mass index, height, gestational age, physical activity, self-reported medical condition, WHO-5 score, and fertility treatment. Main outcome measures: The candidate predictors ability to predict labour dystocia. For model performance, we calculated the area under the receiver operating characteristics curve (AUC) for discriminative capacity and Brier score for model calibration. Results: A total of 12,445 women involving 5,525 events of labour dystocia (44%) were included. All candidate predictors were retained in the final model, which demonstrated moderate discriminative ability with AUC was 62.3% (95% CI:60.7-64.0) and Brier score of 0.24. Conclusions: Our model represents an initial advancement in the prediction of labour dystocia utilizing readily available information obtainable upon admission in active labour. As means of facilitating risk stratification the development of a user-friendly online tool for clinicians is a logical next step. Nevertheless, further model development and external testing across other populations is warranted.

Objective To assess the effect of supervised group exercise on psychological well-being and symptoms of depression among pregnant women with or at high risk of depression. Design Randomised, controlled trial. Setting Department of Obstetrics, Copenhagen University Hospital, Rigshospitalet, Denmark. Population Pregnant women with a current or previous history of depression or/and anxiety requiring treatment within the last ten years, or use of antidepressants three months prior to or during pregnancy. Methods From August 2016–September 2018 the participants were randomly assigned to 12 weeks supervised group exercise from 17–22 weeks of gestation twice weekly, or to a control group. Main outcome measures The primary outcome was self-reported psychological well-being at 29–34 weeks of gestation, measured by the five-item World Health Organization Well-being Index (WHO-5). Secondary outcomes included delivery outcomes and psychological well-being (WHO-5) eight weeks postpartum. Results The analysis showed no significant effect on psychological well-being on the primary outcome. Mean WHO-5 score in the intervention group was 2.0 (95% CI: –1.3 to 5.2, p=0.2) higher than in the control group. Eight weeks postpartum the intervention group reported higher psychological well-being than the control group, mean difference in WHO-5 of 5.5 (95% CI: 1.0–10.1, p=0.04). Conclusions Supervised group exercise did not improve psychological well-being for women with or at high risk of depression at 29–34 weeks of gestation. Eight weeks postpartum the intervention group reported significant higher psychological well-being than the control group.
