Dr. Mattei investigates the genetic, dietary, and psychosocial risk factors of obesity, type 2 diabetes, cardiovascular disease, and allostatic load in racial and ethnic groups as well as underserved and minority populations, as a framework to explain health disparities. Her multiple projects include longitudinal cohort studies in Puerto Rico, mixed-methods projects on diet, stress, and weight stigma, collaborations with epidemiological cohorts of Hispanics/Latinos in the Unites States, and culturally-tailored dietary interventions to prevent type 2 diabetes and heart disease in Boston and Puerto Rico. Her work extends to several Latin American countries through collaborative partnerships. Dr. Mattei promotes evidence-based policy and programs for chronic disease prevention in Puerto Rico and US-Latino communities.
