Incidents of discrimination are a part of everyday life for young people of color, and although many studies document the negative effects of discrimination, we know almost nothing about how it influences health over time. How do experiences of bias and mistreatment play a part in creating racial and ethnic health disparities? This pilot study for Whole Communities–Whole Health is focusing on how technology can help us learn how discrimination affects young people’s physical health. We are testing the feasibility of integrating real-time methods of measurement, including sleep quantity and quality, physical activity, nutrition, and cardiovascular indicators, with daily journal entries and other available community-level data. By examining discriminatory processes and health during adolescence, findings will suggest possible points of intervention, which could have the potential to address how discrimination and chronic stress may lead to a heightened and lasting risk for chronic disease.
