National Steps Challenge

National Steps Challenge: Validation and Insights


The National Steps Challenge (NSC) initiated by the Health Promotion Board (HPB) is a program in which participants use activity trackers to collect steps. HPB provides activity trackers but participants can also sync their own trackers to the Healthy 365 app that is used to monitor progress and provide further encouragement. NSC is now in its sixth season and up until now a large quantity of data has been collected. To more efficiently utilise this data, inform future NSC cycles and to generate valuable scientific knowledge HPB and the PANDA team have established collaborative ties.
