Our Focus

Our faculty and students conduct research on population-level disease prevention, health promotion, health policy, and more. We have a tradition of excellence in research and the application of that knowledge through public health practice and service. Our experienced faculty share their research with community leaders, policymakers, and fellow researchers to better inform the public, respond to emergencies, and provide counsel on emerging health issues facing communities.

Our research- and practice-focused centers specialize in a wide range of important public health topics—including diabetes epidemiology, cancer prevention, and statistical consulting—and are nationally, if not internationally, recognized for their work. Our Center for Global Health is the only World Health Organization Collaborating Center for Promoting Family and Child Health in the Americas. We’re also home to nationally-funded research centers including the Colorado Integrated Food Safety Center of Excellence, one of six centers of its kind funded by the Centers for Disease Control & Prevention (CDC); Rocky Mountain Public Health Training Center, one of 10 centers funded by the Health Resources and Services Administration Agency; and the Center for Health, Work & Environment (one of 10 centers of its kind funded by the CDC).

Resistance, Strategic Compromise, or Complicity? Physicians’ Choices under Ethical Pressure

Matthew K. Wynia

Public Health Impact Statement: I started thinking about writing this essay when some colleagues were let go from their positions at the CDC, others resigned in protest, and still others decided to stick it out despite enormous challenges. I talked about these cases with a colleague, who asked me to formulate some thoughts on complicity and resistance for the Moral Leadership in Medicine conference at Harvard last winter. In doing so, I realized how easy it was for me to judge others as being complicit, or to feel self-satisfied thinking I would do better and be braver if I were in their shoes. But when I thought about specific people who have quit or stayed despite enormous pressure to compromise their professional ethics, I don’t know which actually required more bravery or a stronger moral compass. There are so many factors at play, some of which are private. In a recent book, Defy: How to Speak Up When It Matters, Dr. Sunita Sah also notes that it often takes time to gather the skills and pick the right circumstances to openly defy an injustice. Rosa Parks is an icon of defiance, but imagine how many times in her life she must’ve sat in the back of the bus before she found the right time to refuse; I would never criticize her for taking too long. So, in the end, this article became a plea for empathy toward each other. Science, medicine, public health, and universities are all under enormous ethical pressure today. We need to extend each other some grace and look for ways to support each other. And maybe if we have each other’s backs, it will become easier for each of us to resist pressures to act against our ethics.

Hope and Fear: A Survey of Eco-Emotions and Climate Anxiety, Activism, and Well-Being Among Older Adolescents in Northern California

Kelly L. L’Engle, Julianna Sahoo, Gwendolyn M. Hoff Anderson, Elise Brown, and Lexi Nutkiewicz

Public Health Impact Statement: Climate change is a critical public health challenge, and its mental health impact on adolescents is one we can no longer afford to overlook. As public health professionals, researchers, and communicators, we have a responsibility to address the realities young people face while also fostering the hope and empowerment that fuel pro-environmental action and advocacy. Every young person deserves the chance to pursue their dreams in a safe, environmentally sound world.

Randomized Controlled Trial of Upper Esophageal Sphincter Assist Device in Laryngopharyngeal Reflux Disease

Rena Yadlapati, Lorijane Robles, Mary K Clarke, Eric E Low, Erin Walsh, Amanda J Krause, and Alexander Kaizer

Public Health Impact Statement: Laryngopharyngeal reflux disease is a common condition that can cause chronic cough, throat irritation, and voice problems, yet effective treatments remain limited for many patients. This randomized controlled trial demonstrated that a noninvasive upper esophageal sphincter assist device was safe, well tolerated, and that low pressure in the control arm and higher pressure in the treatment arm both resulted in improved symptoms and lower biomarker burdens. These results suggest that noninvasive strategies may complement or be able to replace pharmaceutical interventions in this population.

Associations of Self-Reported and Actigraphic Sleep with Gut Microbiome Composition and Diversity Among Older Adults

Curtis Tilves, Calliope Holingue, Sarah K Wanigatunga, Chee W Chia, Ni Zhao, Mark N Wu, Jennifer A Schrack, Eleanor M Simonsick, Luigi Ferrucci, Toshiko Tanaka, Adam P Spira, and Noel T Mueller

Public Health Impact Statement: Poor sleep is common among older adults and is linked with adverse metabolic, cognitive, and mental health outcomes, but the biological mechanisms underlying these associations are poorly understood. In our study, both self-reported sleep problems and objectively measured sleep disturbances were associated with lower abundance of the bacterial species, Eubacterium sp. CAG:251, in the gut microbiome. Although these cross-sectional studies require longitudinal confirmation, they identify a potential microbial link between sleep and healthy aging that may ultimately inform new strategies to promote health in later life.
