Population and Global Health (PGH)

The 20th century has witnessed a major breakthrough in human health and wellbeing, with the average life expectancy increasing in virtually all populations. Industrialisation, medical technology, economic growth and behaviour change have contributed in part to this improvement in health.  Improved health status has led to delayed mortality across various populations, but increased the burden of chronic diseases and disabilities.  It is often assumed that morbidity and mortality rates move parallel to one another over time, thus a sustained decline in death rates could be taken as a signal of an equivalent decrease in morbidity rates.  In developing countries, including Ghana, this average rise in life expectancy and urbanisation is taking place against the background of poverty, infectious diseases, high fertility rate and economic stagnation, leading to complex pathways of health transition. 

As mortality rates improve, there is now increased desire to understand the impact of morbidity on various population sub-groups. Therefore, there is the need to take a global view of health in order to successfully address local challenges.

The population and global health component of population studies seeks to equip students with a wide range of current and emerging population health issues in both developed and developing countries. The purpose is to train population scientists to adopt various approaches to estimating population health with emphasis on important risk factors and indicators that influence health outcomes of various population sub-groups. Also, to equip students to understand and research into new confronting challenges. Issues such as the double burden of diseases, Ebola, Zika, etc and their interrelationship with human’s productivity, social security, longevity and overall health status of the population.
