Maternal ethnicity and socioeconomic deprivation: influence on adverse pregnancy outcomes.

To evaluate the relative importance of ethnicity and socioeconomic deprivation in determining the likelihood and the percentage of composite adverse pregnancy outcomes (CAPO) and composite of severe adverse pregnancy outcomes (CAPO-S) METHODS: This is a single centre retrospective cohort study conducted in a tertiary maternity unit. Data regarding the ethnicity and socioeconomic deprivation were collected for 13,165 singleton pregnant women routinely screened in the first trimester for preeclampsia using the Fetal Medicine Foundation combined algorithm. The prevalence or risk of CAPO was 16.3% for White women, 29.3% for Black women and 29.3% for South Asian women. However, half of all CAPO cases (51.7%) occurred in White women. There is a strong interaction between ethnicity and socioeconomic deprivation (as measured with indices of multiple deprivation). Both influence the prevalence of CAPO and CAPO-S, with the contribution of ethnicity being strongest. Black and Asian ethnicity as well as socioeconomic deprivation influence the prevalence of placentally-mediated adverse pregnancy outcomes. Despite this, most adverse pregnancy outcomes occur in White women, who represent the majority of the population and are also affected by socioeconomic deprivation. For these reasons, inclusion of socioeconomic deprivation should be considered in early pregnancy risk assessment for placentally-mediated CAPO. This article is protected by copyright.
