Main objective:
To know the role of Environmental Epidemiology as a methodological tool to approach the main public health issues related to the environment. To learn to identify community health problems and to assess their diverse dimensions (biomedical, environmental, social) through the application of methodological methods. To propose epidemiological designs adapted to each environmental context and to establish the adoption of ideal preventive measures, recognizing and assessing the relationship between environmental factors and community health.
Specific objectives:
• To know the applications of different epidemiological designs to study environmental risks for the population through actual examples.
• To know the main aspects of epidemiological analysis of environmental research and their accurate interpretation.
• To review the most current evidence in the various areas of environmental health and the most appropriate preventive and corrective measures.
• To provide the students with the necessary tools to critically analyze environmental situations entailing health hazards.
• To provide the knowledge to solve actual environmental problems and to evaluate its impact on population health.

Students will be capable of identifying environmental problems and providing the most appropriate answers to each situation.
Students will be capable of evaluating the impact of such problems through the understanding of its effect using the population attributable fraction or specific effects regarding excess risk.
In case-specific studies, the students will be capable of assessing the benefit-risk ratio of specific exposures, such as ionizing radiation.
To assess the importance of adequate measurement of exposure and factors that may exert confusion in epidemiologic studies.
Specific competences of the course
To be able to design epidemiologic studies in an environmental framework and to interpret their results.
To understand the different magnitude of environmental risks and the importance of analyzing specific subpopulations.
To be able to assess the importance of different epidemiologic studies (cross-sectional, longitudinal, and case control) in the analysis of environmental risks effects on health.
The teaching is developed mainly through the virtual campus, where the faculty will provide students with the necessary materials to understand and respond to the teaching objectives, and to solve the assignments and exercises that will be used for the final evaluation.
Each part of the syllabus will include content specifically adapted to its subject and will be available on the virtual campus. The contents will be based on texts in PDF format, highlighting the most relevant and updated bibliography. Key scientific papers, documents and articles from each part of the syllabus will also be available.
The faculty will encourage critical thinking and active learning through reflection-oriented questions and readings. Part of the learning is focused on design thinking and collaborative learning. To this end, several discussion forums will be held on a specific and current topic related to environmental epidemiology. Students will have to answer the questions raised by the faculty, thus collaborating in collective learning by being able to read and discuss the contributions of other students. In addition, throughout the course, each of the faculty members can propose the critical reading of a scientific study related to a specific topic within environmental epidemiology. Furthermore, the faculty will convene short online meeting sessions of voluntary attendance, to explain parts of the theory or to comment on the answers provided in the forums. The faculty will be available to students through the virtual campus and USC’s institutional email.
60% of the overall grade corresponds to the continuous assessment, which considers the participation in forums and the completion of the exercises proposed by the faculty, which will measure the knowledge acquired. The remaining 40% will be reserved for the final test. Students must take an individual test, consisting of the design of a research work applied to environmental epidemiology, or of the argued critique of a scientific article in the environmental field.
Each student should dedicate two or three hours of work per week to the reading of the materials, to the continuous assessment (resolution and elaboration of answers to periodic exercises) and to the final test.
Online participation through e-mail and the virtual campus. Submission of exercises from continuous assessment.
