A strong Public Health dissertation topic combines a defined UK population, a measurable outcome, and a question you can evidence within your word count — from health inequalities and infectious disease control to NHS policy, digital health and global health practice.
Public health sits across epidemiology, policy, environment and behaviour, so undergraduate and masters students can approach the same issue from many angles. Our guide on how to choose a dissertation topic explains how to narrow a broad interest into one answerable question.
The 150+ topics below span ten public health sub-fields, from health inequalities to global health policy. If you would rather have a bespoke topic and proposal built around your interests, our dissertation proposal writing service can help you get started with confidence.

How to Choose the Right Public Health Dissertation Topic
Start with a sub-field that genuinely interests you, then check whether UK data exists — ONS, NHS Digital or Public Health England archives — before committing, since a topic without accessible sources is unworkable however compelling it sounds.
Consider your access to data: primary research involving patients or vulnerable groups faces ethical approval hurdles many students cannot clear within a single academic year, so a secondary-data or policy-analysis design is often the safer choice for undergraduate work.
Finally, narrow your working title until it names one population, one setting and one measurable outcome — an examiner can assess a focused question far more fairly than a broad survey of an entire public health theme.
