BACKGROUND: For health systems and maternity services to respond effectively to forced displacement, an understanding of the lived experiences of women seeking protection during childbearing is required. This study aim was to systematically review existing literature on the perinatal experiences of forced migrant women. METHODS: We conducted a scoping review including MEDLINE, CINAHL Plus, Web of Science and PsychINFO databases and manual search of references. Included studies were quality-assessed and analysed using inductive thematic synthesis. FINDINGS: In total 39 studies were included, involving 624 forced migrant women in 12 countries. Three inductive themes were: (1) "The nature of being a forced migrant," describing multiple liminalities experienced by women; (2) support during the perinatal period, showing women's (re)negotiation of shifting kinship and support networks; and (3) interactions with maternity services, revealing variations in maternity care experiences. CONCLUSION: Findings highlight the systemic power structures forced migrant women must (re)negotiate during the perinatal period and the supportive and empowering role maternity services can play through provision of woman-centred care. Further research is needed to understand the lived perinatal experiences of forced migrant in low-income and transit country contexts.
