Host-country language proficiency and migrant-native disparities in prenatal care utilization: A nationwide study in Portugal

Abstract

Background: Migrant-native disparities in perinatal health and care utilization are well-established, yet most evidence comes from countries without universal health coverage. Migrant-specific factors potentially contributing to such disparities are seldom examined. We investigated the association between migration and host-country language proficiency and inadequate utilization of prenatal care (PNC) in Portugal. Methods: We used robust Poisson regression to analyze data from 1419 migrant and 2477 native women enrolled in the Portuguese Bambino cohort study who had given birth at a Portuguese public hospital between 2017 and 2019. Migrant women's language proficiency was self-rated for understanding, speaking, reading, and writing skills. PNC utilization inadequacy was assessed using three dimensions: initiation, number of visits, and the modified Adequacy of Prenatal Care Utilization (mAPNCU) Index score. Results: Migrant women were overall more likely to initiate PNC late and have inadequate/intermediate mAPNCU scores than natives. Migrant-native disparities in the number of PNC visits were only observed among recent migrants (≤5 years in Portugal). Full, intermediate, and limited Portuguese skills were associated with increasingly higher risks of late PNC initiation (aRR 1.34 [95%CI 1.20-1.50]); (aRR 1.52 [95%CI 1.28-1.80]); (aRR 1.91 [95%CI 1.52-2.40]), inadequate number of PNC visits (aRR 1.06 [95%CI 0.93-1.22]); (aRR 1.14 [95%CI 0.97-1.34]); (aRR 1.57 [95%CI 1.19-2.07]), and inadequate/intermediate mAPNCU scores (aRR 1.18 [95%CI 1.07-1.32]); (aRR 1.30 [95%CI 1.11-1.53]); (aRR 1.69 [95%CI 1.38-2.07]) compared with native Portuguese skills, respectively. Conclusions: Migrant-native disparities in PNC utilization are present in Portugal, despite universal health coverage. Recent migrants and women with limited language competence are the most vulnerable to inadequate PNC use. © 2022 Wiley Periodicals LLC.
