Perinatal mortality in women in minority ethnic groups in Ireland (2011-2021)

Abstract Women in minority ethnic groups (MEG) have been consistently overrepresented in the National Perinatal Epidemiology Centre (NPEC) Perinatal Mortality (PM) reports in Ireland (IE). International research, report similar findings. A secondary analysis of NPEC PM national clinical audit data (2011-21) examined factors associated with PM in women in MEG and differences between these and white women. Maternal sociodemographic and obstetric characteristics, maternal medical history, infant characteristics and PM outcomes of women in MEG were analysed and compared with women of white ethnicity with χ2 tests. There were 4314 PMs in IE from 2011-21; 2896 stillbirths (SB) and 1418 early neonatal deaths (ENND). Women in MEG who experienced PM were younger (p < 0.001) and 46% were employed (vs 75% of white women, p < 0.001). A greater proportion of women in MEG had previous pregnancies (77% vs 68%, p < 0.001), and more than twice as many had ≥3 previous completed pregnancies versus white women (26% vs. 12%, p < 0.001). Women in MEG also had more previous pregnancy medical issues (49% vs 38%, p = 0.001). Twice as many women in MEG had their first prenatal appointment after 20 weeks’ gestation or never received prenatal care (p < 0.001). Analysing by type of PM, statistically significant differences persisted for all these variables in both SB and ENND groups. Women in MEG experienced more placental conditions and obstetric factors as causes of PM, but fewer congenital anomalies compared to white women (p = 0.047). These differences only persisted in the SB group when data was analysed by type of PM. Factors highlighted in this study such as employment, parity, and prenatal care access may explain the over-representation of women in MEG in PM. These findings provide further knowledge useful to create targeted interventions (e.g. initiatives to improve maternal health literacy for women in MEG). Further studies are needed to promote change that would specifically address these systemic inequities. Key messages • Data shows systemic inequities that may contribute to the over-representation of women in minority ethic groups in perinatal mortalities. Clear and tangible changes are needed to address these issues. • Further research needs to clarify factors restricting access of women in minority ethic groups to prenatal care and promote interventions to ensure adequate prenatal care is available and accessible.
