Differences in postpartum mental healthcare among women with identified needs: the role of migration status.

Aims: The aim of this study was to examine the association between women's migrant status (majority, immigrant, descendant) and use of postpartum mental healthcare and investigate whether migration characteristics are associated with mental healthcare use.

Methods: Retrospective cohort study. We included all mothers of children born between 2002 and 2018 in 34 municipalities of Denmark who had an identified mental health need as clinically assessed by a child health visitor (CHV) or by a score of 11 or more on the Edinburgh Postpartum Depression Scale (EPDS). Women were followed until the first mental healthcare received 2 years' postpartum, death or emigration. Using Cox regression models, we estimated the time to mental healthcare by migrant status and explored the role of migration characteristics.

Results: A total of 29% of women (n = 45,573) had a mental health need identified by the CHV, and 7% (n = 4968) had an EPDS ⩾ 11. Immigrants accounted for 19.5%, and descendants for 4.7% of the sample. Immigrants were at lower risk of using mental healthcare than the majority group (CHV: hazard ratio adjusted (HRa) 0.75 (0.70-0.79), EPDS: HRa 0.67 (0.58-0.78)), as were descendants (CHV: HRa 0.77 (0.70-0.86), EPDS: HRa 0.69 (0.55-0.88)). Among migrants, those not refugees, newly arrived, whose partners were immigrants or descendants, and those originally from Africa showed a lower risk of using postpartum mental healthcare.

Conclusions: Our findings emphasize the need to strengthen access to mental healthcare for immigrants and descendants experiencing postpartum mental health concerns and consider migration characteristics as indicators of potential inequalities in access to maternal mental healthcare.
