This interactive course from The Open University explains how our living habits and factors such as societal pressures and inequality can affect our health and contribute to nationwide obesity levels.

Recent decades have seen a drastic rise in obesity, as well as other health problems, across the developed world.

But is our health and wellbeing determined primarily by genetics, or is our 'lifestyle' the main contributor?

This course from The Open University seeks to provide answers to the 'nature or nurture' question by examining the impact of psychosocial factors on one's health.

Dr. Mathijs Lucassen is a psychiatrist at the Faculty of Wellbeing, Education and Language Studies, while Dr. Manik Gopinath is co-lead of the Centre for Ageing and Biographical Studies Research Group.

From poverty to healthcare access, Lucassen and Gopinath focus on the main contributors to obesity in the U.K., and the government interventions tackling this problem.
