New Study: Stress Linked to Racism May Be Making Childbirth More Dangerous For Black Women

Many people see childbirth as a joyful and celebratory experience, but for Black women in the United States, the experience is often overshadowed by a harsh reality. According to the Centers for Disease Control and Prevention (CDC), Black women are three to four times more likely to die during childbirth than white women. As we observe Mental Health Awareness Month this May, a new study suggests that the stress of navigating social and environmental disparities doesn’t just take a psychological toll on pregnant Black women, but may also be a key reason why childbirth can be a matter of life and death.

Research from the University of Cambridge, which examined how external pressures alter a woman’s biology during pregnancy, found that for Black women, the body’s response to racism acts as a “biological pathway,” converting outside stress into actual physical harm. Published in Trends in Endocrinology & Metabolism, the study points out that systemic racism, economic struggles, and environmental stress are major reasons for the differences in maternal and infant death rates between Black and white women.

The study found that ongoing stress can overload the hypothalamic-pituitary-adrenal (HPA) axis, which is the body’s stress-response system, according to the Cleveland Clinic. When the HPA axis is disrupted, stress hormones, such as cortisol, are elevated. Over time, this imbalance can lead to vascular changes that reduce blood flow to the placenta and increase the risk of complications like preeclampsia. The research also points to increased oxidative stress and weaker antioxidant defenses, which are linked to preterm birth. For context, the CDC says Black women are about 50 percent more likely to have a premature birth than white women.

Stress also impacts the immune system. During pregnancy, the mother’s immune system changes to help protect the baby. But when stress alters the body’s inflammation levels, it can lead to preeclampsia, low birth weight, and preterm birth. These problems affect Black women more often than others.

Ultimately, these findings point to a pattern that demonstrates stress-related changes in the body are closely linked to the complications that continue to make childbirth more dangerous for Black women.
