Professional Bio

Dr. Uriyoán Colón-Ramos is a public health nutrition investigator with expertise working in Latin America and the Caribbean, and with underserved populations in the United States.  She is trilingual (Spanish, French and English) and has worked extensively in the field of nutrition in global health through collaborations with the Instituto Costarricense de Investigación y Enseñanza en Nutrición y Salud, the PanAmerican Health Organization, the University of Puerto Rico, the University of Costa Rica, the Instituto Nacional de Salud Pública de Mexico, and the World Food Programme, among others.   Her work has contributed to the knowledge of existing dietary disparities among Hispanic subgroups by country of origin, the process of translation of science into nutrition policy in Latin America, and the social and environmental determinants of dietary behaviors among vulnerable populations in the US, Latin America and the Caribbean.

Dr. Colón-Ramos holds a Bachelor of Arts, and a Master’s in Public Administration from Cornell University.   She obtained her doctorate in public health nutrition from the Harvard School of Public Health under a Ruth L. Kirschstein National Research Service Award Fellowship.  She was the recipient of a Cancer Research Training Award Fellow to complete her postdoctoral studies at the National Cancer Institute, National Institutes of Health in the United States.  In 2004 the United Nations University named her an emerging leader in nutrition in Latin America.

Project Description

This secondary data analysis uses structural equation models to determine how the family environment, in the context of social drivers, impact diet quality among Hispanic/Latino adult and youth. Although the importance of adopting a healthier lifestyle through modification of diet has been well established, Latinos continue to have among the highest rates of type 2 diabetes (T2D) morbidity and related risk factors (1-4). Interventions that seek to address health behaviors by changing the built environment may be hindered or facilitated by social drivers of health behaviors (5-7). Yet, there is limited evidence on how social drivers, such as Hispanic ancestry, nativity and economic variables, interact with the family environment to impact behaviors(17-19). Family environment can modify how people react to stress, and how parents react to children and model the home food environment. Stress and the home food environment have a direct impact on food choice and cardiometabolic risk (8-13). Using a unique data set that includes behaviors and sociocultural characteristics among Latinos, I propose to provide in-depth understanding of the underlying mechanisms of family environment and diet, within a social context. This analysis is expected to advance our understanding of social drivers and health disparities to achieve healthier communities.

Why did you apply to New Connections

Growing up with limited resources in Puerto Rico shaped my interest in diet and health disparities. Today, in my classes, I often draw upon those lived experiences to illustrate the social and environmental determinants of behaviors, specifically around diet. I applied to New Connections seeking just that: ‘new connections’ with individuals and researchers from other disciplines who shared lived experiences similar to mine and who had integrated these experiences, perspectives and lived experiences with their expertise in order to make interventions for underserved populations more impactful.

Research Interests

Dr. Colon-Ramos’ research examines social, structural, racial/ethnic disparities in diet in order to facilitate nutrition-preventive behaviors. The focus of her work has been on populations of the US, Latin America and the Caribbean who are vulnerable to diabetes, cardiovascular disease and obesity. She employs mixed methods and participatory approaches to document, understand, and address cultural and socio-environmental drivers of diet behaviors.  Dr. Colón-Ramos brings a unique perspective rooted in sociology and policy to the field of nutritional sciences.

Her work was among the first to identify significant differences in food group intake among Hispanic subgroups by country of origin, with potential implications on the delivery of health promotion messages and programs in this diverse group. Among immigrants, this emphasizes the need to consider habits and social, ecological determinants in the country of origin. Her work has also contributed to the process of nutrition policy around trans-fatty acids in Latin America, and to the social and environmental determinants of diet behaviors among underserved populations.  More recently, her focus has been on the interactions between neighborhood, home and sociocultural determinants of diet (including drinking water), seeking to identify how to engage community partners to improve nutrition.
