Dr. Brennan Rhodes-Bratton’s research aims to understand how societal structures, such as structural racism, gentrification, and food stigma, impede healthful eating attitudes, dispositions, and practices of mothers across the lifespan, which in turn influence cardiometabolic health outcomes of their children. Dr. Rhodes-Bratton approaches her work using theories and methods from sociology, epidemiology, nutrition, and urban studies. She has developed a theoretical framework of food health lifestyles (FLT) and food habits to examine how neighborhood change can influence health outcomes. FLT is used to inform and create effective health equity programs for communities of color most impacted by social forces responsible for inequity.
