Researchers recruited 422 Black women aged 30–46. Participants answered questions about their experiences with police, worries about future personal contact with police, and worries about how police might treat their children. The team placed women into three groups based on these answers.
The researchers measured carotid intima-media thickness (IMT) using ultrasound. IMT is the thickness of the inner layers of the carotid artery and acts as a marker of cardiovascular risk because thicker measurements suggest a higher chance of future heart problems.
The study found that concern for children’s possible police encounters was linked to thicker IMT, even when women had not reported direct harassment. The researchers controlled for age and income and said the study shows correlation, not causation.
