Run by School of Health Sciences

20 Credits or 10 ECTS Credits

Semester 1

Organiser: Dr Jaci Huws

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.

Course content

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.
