UArizona Health Sciences Awarded $2.4M to Study Stress and Resilience in Vulnerable Latino Populations

The federal funding will allow researchers to develop programs that weigh cultural factors to promote better health outcomes in communities with high-poverty Latino populations in Yuma County, Ariz.

UArizona Health Sciences Awarded $2.4M to Study Stress and Resilience in Vulnerable Latino Populations

TUCSON, Ariz. – Seeking to better understand the complexities of positive and negative influences on Latino health outcomes, researchers at the University of Arizona Mel and Enid Zuckerman College of Public Health have been awarded $2.4 million from the National Institutes of Health (NIH) to study stress-related chronic disease in underserved populations in conjunction with health advantages that exist in those communities.

“Since the start of the COVID-19 pandemic, the College of Public Health’s leadership and expertise has been more visible and important than ever, and this study is an incredible example of why the college has such a well-deserved reputation of excellence,” said University of Arizona President Robert C. Robbins, MD. “The work of Dr. Carvajal and his team will allow us to better support the health and resiliency of underserved communities, and it is a vital contribution to the University of Arizona’s mission as one of only a few land-grant universities that are designated as Hispanic-Serving Institutions. I look forward to seeing the impact this will have across our state.”

The research project will identify cultural, social and behavioral factors that offer protection in a community with a complex picture of very high rates of diabetes and social conditions that cause stress, such as seasonal unemployment, physical challenges from farm work and lack of health coverage. Yet this population statistically holds other known health advantages relative to the U.S. population as a whole – thought to be rooted in cultural processes and social networks - the team plans to investigate. The more that public health experts can learn about such factors that lead to good health, even within difficult circumstances, the better they can develop health programming for this and other communities.

Scott Carvajal, PhD, MPHScott Carvajal, PhD, MPH, professor of health promotion sciences and director of the Arizona Prevention Research Center (AzPRC), is principal investigator for the four-year grant from the National Institute on Minority Health and Health Disparities, a unit of the NIH.

“This award builds on the vital research being conducted by the Arizona Prevention Research Center that involves community health workers to help improve the health of underserved populations,” Dr. Carvajal explained. “The project will help us learn what cultural characteristics of communities, such as family support and social ties, help keep stress from causing chronic disease.”

In collaboration with community partners, the AzPRC leads the way with an innovative research approach that combines community participation and mixed-methods research.

This research approach will help develop new public health programs that benefit Mexican-descent populations, programs that may be applicable to other populations around the nation. Researchers will interview community members to learn what causes them stress and how they manage the stress they experience. Then they will evaluate stress among community members using questionnaires and measure key biological markers of stress and chronic disease. These results then will guide the development of programs to reinforce protective social ties, and concurrently the team will work with community partners to develop plans to mitigate the stress factors that cause the most harm.

Maia Ingram, MPHThe project builds on 20 years of collaboration with a community partner in Yuma, Campesinos Sin Fronteras, which has pioneered community responsive programs to promote the health of farm workers and their families in southern Yuma County. Maia Ingram, MPH, AzPRC co-director and study co-investigator, said, “Campesinos was founded by community health workers who are part of the farmworker community in Yuma County. Their collaboration will ensure our project is responsive to the needs and priorities of southern Yuma County residents. This includes farmworker families, but also others in this economically vulnerable community.”

In addition to the UArizona public health team and community partners, the project includes faculty members from the College of Nursing and the Department of Psychology in the College of Science. Dr. Carvajal added, “Although the project was planned before the COVID-19 pandemic, our team is aware it has intensified social and health inequities and simultaneously created new stressors. The best way to learn about these evolving stressors and identify protective strategies to mitigate their health effects is through research that sustains engagement with community health workers and the communities they represent.”

In October 2019, the center received a $7.5 million, five-year award from the U.S. Centers for Disease Control and Prevention to continue critical collaborations with community health workers and key health organizations in Pima, Maricopa, Yuma, Santa Cruz and Cochise counties, in addition to expanding engagement with community health representatives in tribal communities. As a community-engaged research center, the new programs from the NIH-funded research project will be shared with AzPRC partners in Arizona and across the nation through the national network of Prevention Research Centers.

This research is supported by the National Institute on Minority Health and Health Disparities, an NIH unit, under award No. 1R01MD014150-01A1.
