Division of Epidemiology

Epidemiology involves studying the patterns and distribution of diseases and other health conditions within defined populations in an attempt to understand their determinants and associated factors. Infectious and non-infectious diseases are examined from the perspective of etiology, transmission, surveillance, biomonitoring, screening, and health interventions. Studies targeting patient populations can take clinical epidemiological approaches to address questions of disease diagnostics, patient prognosis, and treatment/intervention efficacy with the goal of contributing to evidence-based medicine and practice. As epidemiology is commonly referred to as the “basic science of public health”, the Division of Epidemiology has the largest faculty reflecting ample expertise in both clinical knowledge and methodology.

Courses Offered by Division Faculty

Epidemiological Methods

This course will cover epidemiological measurements, study designs used in epidemiological studies, analysis of bias and confounding, how to critically analyze a published report, how to write epidemiology-related articles for peer-reviewed journals and how to publish it. Class lectures along with in-class learning exercises, in-class discussion, variety of practical examples from published literature based on health-related problems, homework assignments, text books and reading materials help students to achieve the desired goals. (Required, Spring semester)

Instructors:
M. Rahman

Epidemiology Practicum

This course will cover calculation of epidemiological measurements and associations, analysis of confounding, mediation and moderation using a computing software, how to identify strengths and limitations of epidemiologic studies, and how to use epidemiologic methods to inform the scientific community, economists and policy makers about important health issues. Students will also get deep insight about how to formulate a research question in epidemiology and design an appropriate research study to address that question systematically. Finally, they will get practical hands-on experience about how to write/communicate epidemiological study results to professional audiences and lay people. (Elective, Fall semester)

Instructors:
M. Rahman, O. Takahashi, S. Ohde, E. Hoshino,D. Kobayashi

Clinical Epidemiology

Students will gain the competence in clinical epidemiology necessary for a hospital-based clinical researcher or research assistant to solve clinical questions, generating rigorous scientific evidence based on clinical data. All course activities will focus on the application of epidemiological methods to handle data, especially those obtained from clinical settings. Students will become familiar with the characteristics of various clinical study designs as they relate to diagnosis, prognosis, treatment, prevention, and risk. Students will learn how to prepare study protocols, perform analyses, and present their clinical research, as well as master the basic statistical methods involved. (Required, Fall semester)

Instructors:
O. Takahashi, S. Ohde, E. Hoshino, D. Kobayashi, M. Nojima

Chronic Disease Epidemiology

Morbidity and mortality rates in chronic disease have increased. Consequently, there is increasing importance for early detection, management of disease, and prevention. This class will give students an opportunity to assess the efficiency of examinations and medical treatments and learn about adverse events caused by over-diagnosis and over-treatment. We also will take a look at measurement errors (noise) versus real changes (signal) in screening tests over time and the utility of it in determining appropriate monitoring intervals. (Elective, Fall semester)

Instructors:
O. Takahashi, S. Ohde, E. Hoshino, D. Kobayashi

Molecular Epidemiology

This course focus on understanding various phenotypes (e.g. disease, clinical outcomes, etc.) and its relationship with genetic, environmental, and lifestyle factors using indicators at the molecular level (biomarkers). The identification of molecular markers also has the potential to improve our understanding of disease pathogenesis. This course will provide an overview of pertinent methodological issues specific to the molecular epidemiology of chronic diseases and of available molecular technologies in this era of “omics”, all within the context of relevant examples. (Elective, Spring semester)

Instructors:
K. Urayama, T. Shuo
