What Is a Public Health Dissertation?

A public health dissertation is an in-depth research project that investigates a specific health issue affecting populations. It demonstrates your ability to apply epidemiological methods, evaluate health interventions, analyse public health data, and critically engage with health policy. UK public health dissertations typically range from 8,000 to 15,000 words at undergraduate level and 12,000 to 20,000 words for MPH and MSc programmes, and they should connect to the realities of UK public health practice, NHS policy, or global health challenges.

How to Write a Public Health Dissertation

Writing a strong public health dissertation requires careful planning. Here are the essential steps for UK students in 2026:

Choose a population-level health issue. Public health research focuses on populations, not individuals. Frame your topic around a health issue affecting a defined group — such as “the effectiveness of smoking cessation services for pregnant women in deprived areas of Northern England.” Use epidemiological evidence. Ground your literature review in epidemiological data, systematic reviews, and public health reports from organisations like OHID, WHO, and NICE. Select a robust methodology. Consider cross-sectional surveys, secondary analysis of NHS or ONS data, systematic reviews, qualitative interviews with public health professionals, or mixed-methods designs. Analyse data appropriately. Use SPSS, Stata, or R for quantitative analysis, or NVivo for qualitative coding. Ensure your analytical approach matches your research design and question. Connect findings to policy. Strong public health dissertations make clear links between research evidence and public health policy or practice. Discuss implications for NHS commissioning, local authority public health teams, or national health strategy.
