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

Abstract

AbstractBackgroundMigrant‐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.MethodsWe 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.ResultsMigrant 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.ConclusionsMigrant‐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.
