Background: Neuraxial analgesia (NA) is the most effective modality in managing labor pain with widespread availability in high-income countries. Previous research has reported a differential obstetric NA use among migrant and native women, but the contribution of language barriers is not well understood. We aimed to investigate whether host-country language proficiency among migrant women influences NA use and satisfaction with pain management during labor, when compared to natives.
Methods: We conducted a secondary analysis of data collected from 1024 native and 1111 migrant women who had singleton vaginal deliveries between 2017 and 2019 and were enrolled in the nationwide Portuguese baMBINO prospective cohort study. Obstetric NA use, satisfaction with labor pain management, and migrants' Portuguese language proficiency were self-reported. Data were analyzed using robust multilevel Poisson regression, adjusted for maternal region of birth (characterized by the Human Development Index), age, and education.
Results: Overall, 84.4% of native women gave birth with NA, compared to 81.6%, 71.3%, and 56.9% of migrant women with full, intermediate, and limited language proficiency, respectively. Compared to native women, migrants with intermediate (adjusted risk ratio [aRR] = 0.91 [95% confidence interval {CI}, 0.82-0.99]) and limited (aRR = 0.73 [95% CI, 0.56-0.94]) proficiency were less likely to receive NA. However, no significant differences were observed in pain management satisfaction by language proficiency level.
Conclusions: Compared to native women, we observed a differential obstetric NA use across migrant women with different host-country language proficiency levels in Portugal, without affecting satisfaction with labor pain management. Although defining the mechanisms underlying NA use discrepancies requires further research, our findings support systematically evaluating pregnant migrant women's linguistic skills and ensuring their access to adequate obstetric analgesia-related information and interpretation services.
