Study reveals significant disparities in severe maternal complications for Black people in Canada

A national study examining nearly 1.5 million births in Canada found that Black people experience severe maternal morbidity at nearly double the rate of white people, with 47.8 per 1,000 cases compared to 27.7 per 1,000. After accounting for demographic and clinical factors, Black individuals showed a 66% increased risk of serious pregnancy complications including preeclampsia, hemorrhage, and sepsis. The disparities persisted across income levels and immigration status, indicating that socioeconomic factors alone do not explain the health inequities.

The research examined nearly 1.5 million births across Canadian provinces and territories between 2012 and 2023, utilizing linked census data alongside hospitalization records. The conditions identified as severe maternal morbidity encompassed multiple organ systems and included life-threatening situations such as uncontrolled blood pressure disorders, massive blood loss, infection, and organ failure. The disparity persisted even when researchers isolated specific disease conditions that naturally occur at different frequencies between populations, suggesting the gap cannot be attributed to genetic predisposition.

The study's integration of immigration status data proved particularly significant, as it demonstrated that the elevated risk applied equally to both Canadian-born and immigrant Black populations across all income brackets. This finding challenges assumptions that economic access or migration-related factors alone account for the observed health inequities in pregnancy outcomes.
