Our Research
Everyday life stressors and community level burdens have been shown to alter brain biology. Psychoendocrinology literature shows compelling evidence that stress-induced changes to the body may contribute to obesity and metabolic diseases. Specifically, psychosocial and environmental stressors can disrupt hypothalamic-pituitary-adrenal (HPA) axis activity, which in turn will alter cortisol levels throughout the day.
Disrupted cortisol patterns have been shown to be associated with increased risk for obesity and type 2 diabetes. Work in this area of research has implications for public health and health care practitioners by raising awareness of health risks associated with stress and the need for stress-reduction programs and interventions.
The overarching research aim of the MeSA pilot study to understand the complex relationship between various stressors, HPA-axis activity, and body fat. In this effort, we will characterize perceived, community, and biological stress and assess their relationships with body fat measures.
Since our lab is grounded in clinical epidemiological design, we only use quantitative methods. Our data are collected via self-reported surveys, health behavior assessments, and physiological measures from biospecimens.
Our Team
Professor
Claudia Toledo-Corral is a Professor in the Department of Health Sciences at CSUN and an Adjunct Professor at the University of Southern California (USC). Dr. Toledo-Corral has a background in biological sciences, health psychology, and anthropology/cultural studies, and obtained her M.P.H. and Ph.D. in Preventive Medicine from USC. She has a long-standing research agenda in the field of obesity and associated disease risk in minority populations. Dr. Toledo-Corral’s past work includes the study of the biological underpinnings of pediatric obesity and diabetes risk, assessing the efficacy of clinical diagnostic methods for diabetes, and examining the physiological role of stress on obesity and cardiometabolic risk. To date, she has mentored, and published with, dozens of students at the undergraduate and graduate level (MPH and PhD) at CSUN, CSU Los Angeles, University of Michigan, and USC.
My journey in research began during my undergraduate studies at CSU San Marcos, where I was
an American Psychological Association Research Scholar and a Ronald E. McNair Scholar.
During this time, I conducted research examining the impact of sociocultural stress on fetal
programing and perinatal maternal mental health among women of Mexican descent. This
experience solidified my interest in understanding the effects of sociocultural stressors within
marginalized communities, particularly the Latinx population.
As a graduate student and a Chancellor’s Doctoral Incentive Program Scholar, my research
expanded to focus on stress processes and protective factors through the lens of health
psychology and developmental science, particularly among Latinx adolescents. My work aims to
deepen our understanding of the relationship between stress and health within broader systems of
oppression.
Currently, as a postdoctoral fellow, I hope to continue my work with marginalized communities
and further develop my expertise on the health-related outcomes of discrimination. As a new
member of the Metabolism and Stress Assessment Lab, I am excited to collaborate with a diverse
time and engage with students with a broad range of expertise, to advance this important area of
research.
