Module description
This module will form the foundation of the science of public health. You will be exposed to epidemiology through the study of distributions and determinants of disease in populations and learn to apply the tools epidemiologists use to investigate health and disease in populations how they support public health decision-making for population health.
No pre-requisites or specialist knowledge are required to undertake this module, which is well suited to interdisciplinary learning. Delivery is via six focused sessions of expert-led small group learning, interspersed by personal study undertaken at your own pace, interactive “consolidation” activities and supported by our internet resources.
This module permits students to attend some or all of the face to face lectures and workshops either in person or online. Learning will also be consolidated by self directed learning resources and ELE activities.
Module aims - intentions of the module
In this module you will understand:
- Causality in public health and challenges to understanding causality
- Sources of evidence in epidemiology
- Key forms of bias in epidemiological research
- The contribution of different study designs and data sources to understanding epidemiologic relationship
- How health, wellbeing and risk and protective factors are measured
- How tests and their performance influence public health decisions
- The role of genetics and genomics in shaping epidemiology
