Projects

Healthy Kids | Niños Sanos

Funded by the USDA-NIFA AFRI program and directed by Dr. Marilyn Townsend, this project explores the feasibility of implementing an educational intervention in medical settings to improve feeding practices of EFNEP parents with children at risk of obesity. Partners of this project include HeadStart and the UC Davis Medical Center. As part of this project, Dr. Díaz Rios is exploring the relevance of an educational component consisting of motivational stories and messages, and has conceived and lead the application of a model for the cross-cultural adaptation of evaluation tools (Diaz Rios 2017, Ontai 2016, Diaz Rios 2016).

Food Security Evaluation

In partnership with the GFI Basic Needs Workgroup, Dr. Díaz Rios’ team is conducting a study to explore attitudes and experiences surrounding food access to identify needs and targeted means to improve food access among students at high risk of food insecurity. This project is part of a broader evaluation plan directed by Dr. Díaz Rios to formative, process, and outcome evaluating food security initiatives at UC Merced.

Healthy Beverages in Childcare

Funded by the UC ANR and directed by Dr. Lorrene Ritchie, the aim of this project is to develop and test an online training to help providers overcome barriers to create a healthy beverage environment in childcare settings, in compliance with the California’s Healthy Beverages in Childcare Act (AB 2084). As co-PI on this project, Dr. Díaz Rios is involved in the development and cultural adaptation of materials and evaluation tools.

Project Collaborations

Ortiz Lab – Dr. Díaz Rios is overseeing the collection, analysis, and interpretation of dietary and qualitative data for a project to determine the effects of almond snacking on the metabolic and metabolomics profiles of freshmen students (Dhillon 2018); and to evaluate sensory perceptions of fruits, vegetables, and nuts and their association with metabolic risk among college students. Dr. Díaz Rios has directed a study to explore college student perceptions of their food environment (Dhillon 2017, Dhillon 2019) and is a collaborator on the UC Merced FARMERS, an education project funded by the USDA HIS program.

Gonzalez Lab – Dr. Díaz Rios collaborated with Dr. Gonzalez on a project to examine health and nutritional disparities related to generational status among Mexican-identified Californians (Gonzalez 2015a, Gonzalez 2015b); and is currently co-advising Dr. Gonzalez’s doctoral student, Zahra Goliaei, on a project to explore food security among recently-arrived Afghani refugees (Goliaei 2018).

Ramirez Lab – Dr. Díaz Rios collaborated with Dr. Ramirez on a project to explore the relevance of an intervention to improve access to healthy food in rural food deserts (Ramirez 2017).
