Genetic and sociocultural risk factors for hypertension in African-Americans. Genetic (candidate genes and ancestry informative markers), biological (stress biomarkers), and sociocultural (measures of race, SES, etc) data are analyzed in order to simultaneously test for the contribution of genetic and environmental factors to risk of hypertension. Different methods to measure 'race' are specifically included in order to investigate ideas of identity and implications for human health. Close collaboration with the African-American community in Tallahassee, FL (http://healthequity.us/) is a key component of the study. Graduate student Tamar Carter is analyzing both genetic and sociocultural data in order to more fully understand how to study complex diseases with racial disparities. Collaboration with Lance Gravlee (University of Florida). This work is supported by NSF grant BCS-0820687, entitled "Genetic ancestry, race and health disparities: A biocultural approach").
