Overall aims and purpose
This module aims to develop students' understanding of epidemiological methods as applied to public health and health promotion. Students will develop skills in describing and analysing epidemiological data, critically appraising study designs, and interpreting public health and health promotion issues through an understanding of epidemiological principles. These skills will enable students to understand and challenge issues that impact upon the sustainability of health and public health. PLEASE NOTE: Due to the Covid 19 crisis, the module will be delivered using a blend of teaching approaches including online. Students will be required to have access to IT and up to date computer and software.
The module explores and critically appraises the key concepts of epidemiology and their application to public health and health promotion. The principles of epidemiology will be outlined, and students will develop a critical understanding of the strengths and limitations of different types of epidemiological data and evidence. Course content may include:
- Epidemiological measures of health and disease: frequency (including incidence, prevalence, odds, rates); crude and specific rates; standardisation.
- Epidemiological measures of health and disease: association and impact (risk ratio, rate ratio, odds ratio, risk and rate difference; attributable risk, and population attributable risk).
- Epidemiological design (cross-sectional, cohort, case-study, intervention).
- Interpreting the results of epidemiological studies and focussing on bias, confounding, chance, cause-effect relationship.
- Surveillance and routine data.
- Diagnostic and screening test programmes.
- Critical appraisal of epidemiological research.

|ESSAY||Appraisal and interpretation task||
Select an epidemiological study that has been published in a peer-reviewed journal in the past 10 years: 1. Summarise the study in your own words (300 words); then, critically evaluate the study using an appropriate critical appraisal tool (700 words). (1000 words total; 60% of marks). 2. Using a style appropriate to a lay audience (for example, newspaper readers), outline the public health and / or health promotion implications of this study (500 words; 40% of marks).
Assessed Learning Outcomes: 1, 3 and 4.
Teaching and Learning Strategy
Lectures are supported with additional academic materials and resources. Students are also encouraged to: use library and multi-media resources (such as the Internet, newspapers, radio, television) and engage in Blackboard Group discussions. Students are encouraged to use electronic learning resources. Relevant lecture material, reading lists, and a list of relevant Internet resources are available on the course specific Blackboard site; students are also asked to add any relevant or useful material to this module site.
Lead lectures & group work: The lectures comprise formal presentations, class discussions, seminars, and group exercises. Lectures are interactive and students are encouraged to actively participate and contribute.
Tutorials: Students are required to attend individual and group tutorials to facilitate the development of critical appraisal skills.
Online discussions groups led by students, and moderated by the Module Organiser.
