Abstract

Over recent years, immigration to Europe has risen significantly. This development has led to increasing birth rates by non-Western immigrant women. Maternity care systems are not yet adapted to this increased diversity of women. In Denmark, 13 % of all children are currently born by women originating from non-Western countries. Despite a publically funded antenatal care, non-Western immigrant women have lower utilization of Danish antenatal care compared to other women giving birth.
Many non-Western immigrant women have an increased prevalence of severe maternal morbidity and higher risks of maternal death, stillbirth and infant death compared to the majority populations. Poor health status at birth can impair the cognitive, sensory and motor development and lead to learning disabilities during school age, and thus reduce equality in life chances. Suboptimal care is a contributing factor to these ethnic disparities. Provision of appropriate antenatal care is pivotal to reduce these serious disparities and challenges to public health, however little is known about models of care, which can overcome these barriers.
The MAMAACT intervention was developed to increase response to symptoms of pregnancy complications among maternity care providers as well as non-Western immigrant women. The intervention consisted of postgraduate training of midwives in intercultural communication and health education materials (leaflet and an app) for non-Western immigrant women describing how to respond to warning signs during pregnancy in six different languages, The intervention was implemented at 10 out of 20 Danish maternity wards as part of a national trial from the year 2018 to 2019, potentially reaching 25.000 pregnant women, including 2500 of non-Western origin.
This workshop shares insight into innovative ways of providing antenatal care for non-Western immigrant women and will focus on methodological aspects of scientific evaluation of complex interventions for vulnerable populations. The workshop includes an introduction, three presentations, and a discussion with the audience.
Using quantitative data, the first presentation will give an overview of ethnic disparities in stillbirth and infant death in Denmark. The second presentation will present qualitative data from the implementation evaluation of the MAMAACT intervention with a focus on the interventions program theory, methodological considerations and evaluation results. Finally, the third presentation will illuminate how the concepts of Health Literacy and cultural health capital contribute to an understanding of mechanisms leading to ethnic disparities and how they can be used for evaluating the impact of the MAMAACT intervention. The final discussion will stimulate knowledge sharing between the participants on how to combine quantitative and qualitative insights in trials, how to build partnerships and recruit vulnerable populations in evaluations, and how to use sociological theory in evaluations.

Key messages
Reducing ethnic disparity in reproductive health requires maternity care systems to rethink their antenatal care services so they are better equipped to support non-Western immigrant women’s needs. Sharing knowledge on the use of mixed methods, recruitment of vulnerable populations, and the use of sociological theory can contribute to future approaches to evaluate complex interventions.
