Public Health Challenge 2021




According to the World Health Organization, physical activity can be defined as any bodily movement produced by skeletal muscles that requires energy expenditure. 


Locally, a WHO study in 2018 indicated that 1 in 3 Singaporeans do not engage in enough physical activity. This troubling statistic is worsened by the COVID-19 pandemic, especially during the circuit breaker and the recent Heightened Alert periods, where most students had to spend the bulk of their time at their desks listening to online lectures. Thus many have gotten used to the sedentary lifestyle promoted by COVID-19. 


Lack of physical activity is strongly associated with increased risk of developing irreversible chronic diseases such as heart disease, stroke, and type-2 diabetes.


As such, for this year’s challenge, you are tasked to design an implementable solution that tackles the issue of physical inactivity within NUS. Do note that your ideas will have to be contextualised in the “new normal” settings that we are currently living in COVID-19 pandemic. We look forward to students engaging in constructive discourse and in putting forth their best solutions to tackle this pertinent and pressing issue.

Tasks of the Team

  1. Identify a specific target audience you want to intervene.

  2. Identify the main goal of your solution (i.e., the behaviour you want to target and improve on) by utilising the SMART principles.

  3. Propose workable and practical steps towards fulfilling a public health goal for a specific community (e.g., how to get NUS students to go for smoking cessation) using at least one of the Public Health Frameworks.

Additional Information:

  1. The medium of proposals may include but not limited to technological interventions, public health programmes, process improvements, structural changes and behaviour shaping advocacy work on campus

  2. It is highly recommended to avoid creating an application based solution as it is not feasible and challenging for PHS to provide the necessary resources to translate the project into reality. 

  3. Teams are to evaluate the feasibility, sustainability (both short-term and long-term), innovativeness and its relevance to NUS in their proposals. 

  4. As a follow-up to PHC2021, NUS PHSoc would then be collaborating with the winning project team to translate the project into reality.
