We Like Fried Things: Negotiating Health, Taste And Tradition Among Spanish Caribbean Communities In New York City, Melissa Fuster
Publications and Research
The study was conducted to understand fried-food (FF) consumption among Hispanic Caribbean (HC) communities in New York City. Data were collected through qualitative interviews with 23 adults self-identified as Cuban, Dominican, or Puerto Rican. Most informants considered FFs an important part of their traditional diet. Potential explanations included taste, cost, convenience, and the emotive values attached to FF. FF consumption was contextualized in local foodscapes. Results include strategies to diminish FF consumption and differences across HC groups and migratory generations. The relevance for future nutrition interventions addressing health disparities in this community is discussed

Disparities In Infant Mortality: Are Sociocultural Risk Factors Shaped By Institutionalized Racism?, Madison Grimm
Honors Program Theses
The infant mortality rate (IMR) is an incredibly important indicator of the overall health of a nation. Because the IMR is so closely related with factors such as quality and accessibility of healthcare and socioeconomic conditions, it is helpful in evaluating a nation’s success. The United States (US) has one of the highest infant mortality rates among countries with a similar degree of economic development (those belonging to the OECD). In 2013, the IMR was 5.96 deaths per 1,000 live births, according to the Centers for Disease Control and Prevention, or CDC (Mathews, MacDorman, & Thoma, 2015). Furthermore, this rate …
