In the BigO project students become citizen scientists. They collect information about their lifestyle, health behaviours and the environment they live in. They do this with a specially developed app called ‘myBigO’ (available for Android and iOS. By answering questions, taking pictures of foods they consume and food advertisements they encounter in their living environment (i.e. never exact locations, always anonymized), the citizen scientists collect data about their behaviour and local living environment (see video). This data is anonymized, the exact locations and identities of students is never known or stored.
This information is used to find out what places in Europe and what behaviours need more attention in public health policies in order to counteract obesity in children.
The information gathered by the citizen scientists, is being used to create models of how the various environmental and behavioural factors influence the prevalence of obesity. Because of the amount of information available data that is collected, scientists will be able to create complex models to predict how specific policies will effect obesity levels in the communities.
The BigO project can in this way be used to help public health authorities design strategies that are more effective in promoting health and lowering obesity rates in children.
On the BigO YouTube channel you can find more information on how the app works.
