EHS 544a, Climate Equity and Health Policy Methods Suzi Ruhl
Climate change presents threats to human health and well-being, while escalating health inequities. These health impacts can be direct, indirect, and cumulative. Concomitantly, efforts to prevent and respond to climate change can offer beneficial health impacts to vulnerable and disadvantaged populations. This course focuses on policy research methods, offers a policy to practice approach, and is accountable to communities most vulnerable to climate change. As a foundation, the course explores the “face of climate inequity” considering structural biases, social inequities, and racism that undermine health and create challenges for those most vulnerable to climate change. It also increases awareness of cultural values and practices that should be considered in the design, implementation, and evaluation of climate equity and health policies and programs. Further, the framework of the course triangulates rule of law, evidence-based methodologies, and meaningful engagement. It introduces the basic principle of “rule of law” as a means to navigate government policy making with an understanding of administrative law and relevant environmental laws. It builds on this foundation to explore policy methods buttressed by evidence that is based on academic and lived experience expertise. It addresses mapping tools and data analysis accountable to disadvantaged populations. It incorporates consideration of “meaningful engagement” of vulnerable populations, with a special focus on the disproportionate impacts of climate change on the whole health of disadvantaged individuals, families, and communities. Further, key health topics are highlighted through integrative case studies, including climate resiliency and family mental health and health care systems. Innovation at the state and local levels of government are also addressed. Throughout the course, attention is directed to integration of these concepts through applied learning. Prerequisite: EHS 547 or permission of the instructor.

[ EHS 563, Biomarkers of Exposure, Effect, and Susceptibility in the Epidemiology of Noncommunicable Disease ]
This course explores how new biomarker approaches can be applied to understanding the health consequences of environmental exposures and other risk factors. We learn how advances in the measurement of environmental exposures, genes, proteins, metabolites, and the microbiome have strengthened epidemiological associations and narrowed the gap from correlation to causality. Variability in biomarker performance and susceptibility to disease due to ageing, diet, location, and other factors is discussed, along with methods that are used to evaluate biomarker evidence in epidemiology. Lectures describe chronic noncommunicable diseases of immediate concern to public health such as neurodegenerative diseases (Alzheimer’s disease, Parkinson’s disease), cancer, cardiovascular diseases, and asthma. We examine seminal publications and the application of techniques that have transformed the understanding of each disease, resulting in improvements to early detection and treatment approaches for these diseases. We also delve into examples of epidemiologic studies that have been carried out on large prospective cohorts, such as the Framingham Heart Study and Nurses’ Health Study, and compare and critique methods used to identify biomarkers of disease between the cohorts. To evaluate and foster greater understanding of these areas, students critique journal articles for homework assignments. 1 Course cr
