We take you through what studying public health involves, why to study in the field and the areas you can work in.  

 

What is public health?

 

As a point of departure for our discussion, it’s useful to look at exactly what public health is. Public health aims to ensure the health and well-being of individuals, communities and wider society through organised processes and measures. It seeks to reduce the risk of a negative impact on health from numerous factors, for example, pollution and nutrition. Some of the work undertaken in public health is designed to address the specific needs of certain distinct groups, such as the elderly or children. Public health may also involve:

 

  • Health awareness campaigns 
  • Prevention of disease strategies 
  • Vaccination 
  • Monitoring and evaluation of health 
  • Health education 
  • Health support services

What areas will I study for a degree in public health?

 

It’s important to note that a course in public health is usually studied at a postgraduate level after the completion of a related undergraduate degree or qualification. Public health can be studied at certificate, diploma, honour’s or master’s degree level. As public health is multidisciplinary, you may find that the entry requirements for a course consider what is known as ‘recognition of prior learning’, which evaluates the applicability of your qualifications for entry onto the course. You will also find that some public health courses can be studied fully online

 

If you choose to pursue a degree in public health there are some common topics that you could find yourself studying. These include:

 

  • Social research 
  • Public health policy
  • Epidemiology
  • Health services
  • Health economics
  • Health management 
  • Health and conflict 
  • Statistics 
  • Global health 

 

To gain entry onto an MSc in public health course you will need to have a very good level of English language proficiency. Most courses will require an overall IELTS score of 7.0 and bands that do not drop below 6.5. You will also need to have a good undergraduate level of achievement (2:1 degree/ B average/ or GPA of 3.3). 

 

Studying for a postgraduate certificate or diploma in public health will take you a year of full-time study and between two and four years to complete part-time. An MSc degree in the subject will need an allocation of one year full-time and one to three years full-time. It’s important to double-check with your prospective university as to the completion timeline requirements.
