Abstract
Toxic stress is characterized by physical, psychological, and environmental stress that is detrimental to one’s health. The stress pathway is believed to be involved in preterm birth via inflammatory and immunologic dysregulation. We conducted a cross-sectional study on female participants aged 15-45 years old who delivered a live, singleton infant at Magee Women’s Hospital in Pittsburgh, PA. Each participant was assessed for risk of toxic stress using a combination of individual level factors and neighborhood deprivation scores and subsequently assigned a risk group. We hypothesized that levels of pro-inflammatory and anti-inflammatory cytokines in the first trimester differ by risk group and race. We found that Black females were more likely to be at risk for toxic stress and had lower median levels of IL-6 compared to White females. When stratified by risk group and race, low risk Black females had lower levels of IL-10 compared to low risk White females and high-risk Black females had lower levels of IL-6 compared to high-risk White females. Our results suggest the relationship between toxic stress and inflammatory cytokines is modified by race. It is our theory that exposure to repetitive stress due to racism and lifelong social disadvantage, results in desensitization of the stress pathway and a blunted adaptive response to future stressors. Understanding the mechanisms involved in the disparities in preterm birth are of the upmost public health significance.
