Perinatal Health Promotion in Indigenous Maternal Health: A Scoping Review of Peer-Reviewed Evidence and Australian...

Indigenous women experience a disproportionate burden of adverse perinatal health outcomes, yet the extent and nature of health promotion interventions addressing modifiable behavioural and social determinants remain poorly synthesised. This scoping review mapped smoking, nutrition, alcohol, physical exercise, and social and emotional wellbeing (SNAPS(o))-related perinatal health promotion programs delivered through Australian Aboriginal Community Controlled Health Organisations (ACCHOs), supplemented by relevant peer-reviewed evidence identified across Australia, Aotearoa New Zealand, Canada, and the United States. A two-phase design looked at peer-reviewed literature from January 2010 to January 2025 across PubMed, CINAHL, and the Cochrane Library, followed by a structured review of Aboriginal Community Controlled Health Organisation (ACCHO) websites in Australia (n = 145). Data were extracted on program characteristics, SNAPS(o) components, implementation models, and evaluation outcomes. Findings were synthesised using content analysis. Thirty-four programs were identified in total, most delivered through ACCHOs (n = 26) and predominantly implemented in Australia (n = 29). Smoking was the most frequently addressed component (n = 18, 55%), while nutrition and social and emotional wellbeing were each included in 27% of programs (n = 9), physical exercise in 18% (n = 6), and alcohol in 15% (n = 5). Grey-literature programs more commonly reflected multi-component, holistic models compared with peer-reviewed studies and formal evaluations. Only 10 programs had identifiable formal evaluation evidence, including published or publicly reported evaluations, almost all of which were identified through academic sources. Evaluations focused primarily on tobacco-related behavioural outcomes, with limited reporting of sustained maternal or infant health endpoints. The perinatal SNAPS(o) intervention landscape for Indigenous women is characterised by strong community-controlled delivery but limited published evaluation, particularly of integrated models implemented within ACCHOs. The concentration of evidence on smoking cessation highlights a need to expand evaluation across broader domains of maternal wellbeing. Strengthening Indigenous-led evaluation frameworks and outcome measures that reflect holistic models of care is essential to advancing equitable and culturally grounded perinatal health systems.
