Adolescents who experienced frequent racial discrimination without emotional support from parents and peers had higher levels of blood pressure, a higher body mass index, and higher levels of stress-related hormones at age 20, placing them at greater risk for chronic disease as they get older.
Researchers wanted to look at the relationship between racial discrimination and what scientists call allostatic load, basically the "wear and tear" on the body over time caused by frequent and repeated stressors. Frequent activation of the body's stress response causes a cascade of problems including high blood pressure, cardiac disease, stroke and increases in the body's inflammatory response. The researchers also wanted to determine whether parental and peer support would help mediate that stress, leading to potentially better health outcomes.
The study involved 331 African Americans, all of whom lived in the rural South, who were asked to rate the frequency of perceived discrimination at ages 16, 17 and 18. These discriminatory events included racially based slurs and insults, disrespectful treatment from community members, physical threats, and false accusations from business employees or law enforcement officials.
