Holistic antenatal education class interventions: a systematic review of the prioritisation and involvement of Indigenous Peoples’ of Aotearoa New Zealand, Australia, Canada and the United States over a 10-year period 2008 to 2018

BACKGROUND: Research into the effectiveness of antenatal education classes is crucial for Indigenous Peoples from Aotearoa New Zealand, Australia, Canada and the United States who experience poorer maternal and infant health outcomes compared to non-Indigenous populations. Our systematic review questions were intended to determine the extent of Indigenous Peoples prioritisation and involvement in antenatal education classes, and to understand the experience of Indigenous Peoples from these countries in antenatal education classes. METHODS: Using a standardised protocol, we systematically searched five electronic databases for primary research papers on antenatal education classes within the four countries noted and identified 17 papers that met the criteria. We undertook a qualitative meta-synthesis using a socio-critical lens. RESULTS: Systematic review of the academic literature demonstrates that Indigenous Peoples of Aotearoa New Zealand, Australia, Canada and the United States are not prioritised in antenatal education classes with only two of 17 studies identifying Indigenous participants. Within these two studies, Indigenous Peoples were underrepresented. As a result of poor engagement and low participation numbers of Indigenous Peoples in these antenatal education classes, it was not possible to understand the experiences of Indigenous Peoples. CONCLUSION: Given that Indigenous Peoples were absent from the majority of studies examined in this review, it is clear little consideration is afforded to the antenatal health needs and aspirations of Indigenous Peoples of Aotearoa New Zealand, Australia, Canada and the United States. To address the stark antenatal health inequities of Indigenous Peoples, targeted Indigenous interventions that consider culture, language, and wider aspects of holistic health must be privileged.
