barn som ritar Grand Challenge

Time for Hackathon!

From December 21, you can register your team for the first phase, Hackathon, in our Grand Challenge. We challenge you and your team to develop your idea of how childhood obesity can be prevented and give everyone an equal health start in life.

Your idea must be behaviour-changing, innovative and have good potential to reach a market and create an effect. We do not want to place restrictions on whether your idea will result in a product, service, policy or tool – we open up to be surprised by your initiative and commitment. In the questions-and-answers below, we give you some direction through a target image for the results that are sought.

The hackathon will be carried out throughout March 2021 and is a co-arrangement between SAS Global Hackathon and the project. During the month of the Hackathon, we give you as team support through virtual events and the competition platform.

The hackathon ends on March 31. Then the teams must have sent in films where they present their concept proposal and a short pitch of how their concept will prevent obesity in children of preschool age. The films and the associated pitch will be judged by a jury tasked with evaluating and ranking the competition entries. The outcome of the assessment will be presented at a final event in April.

During January until the start of the Hackathon in March, we will gradually provide additional information about the structure and conditions for participation.

Does that sound tricky? No worries! We will guide you all the way. But now register your team for the Hackathon, and you will continuously receive information.


Registration is closed.

Scope for The Grand Challenge Prevent Childhood Obesity Hackathon.


1. Paula Frösell, ICA. Changing behaviour – the need for an in-depth understanding of the difficulties of changing eating habits

In the pitch, Paula points to the low compliance that exists when it comes to national advice for food and physical activity. Many in society know what to do, but few will change. The team is challenged to develop solutions that help create a behavioural change. The solution must be able to mobilize companies, healthcare and other actors to be able to offer guardians incentives to change their behaviour and prevent childhood obesity.

2. Jenny Vinglid, HOBS. Promote conversation and dialogue – to talk and inform about children’s health in a non-stigmatized way

How can visualization or other digital services, for example, facilitate communication and interaction between guardians, child welfare centres (BVC) and preschool staff so that dialogue about child obesity does not stigmatize? A central target group here are first-time parents as guardians but also the staff at BVC who need support and tools that promote dialogue with and coaching of families who risk being affected by obesity without the child and the family being blamed.

3. Maria Bjerstam, Region Skåne and Innovation Skåne. Promoting physical activity in preschool children – data-driven evaluation and comparison of preschool outdoor environment

Increased physical activity is a way to counteract childhood obesity. How to promote preschool outdoor environments to activate preschool children. Through the need, teams are challenged to use digital technology (eg image comparison) to develop tools and working methods that enable employees at the preschool and within the municipality to evaluate and compare preschool’s outdoor environments from an activity perspective.

4. Paula Frösell, ICA. The healthy choice in a stressful everyday life – a personalized solution to make it easier to eat healthy in the everyday life puzzle

In this pitch, the team is challenged to create solutions that help parents in the stressful everyday life to choose the right one in the middle of the puzzle of life so that the family can eat healthily. ICA has a lot of data and understanding of purchasing behavior and how families think about e.g. prescription. How can a personalized solution be designed that, through positive incentives, facilitates healthy choices at the moment.

5. Peter Bergsten, Uppsala University. Data-driven simulation of interventions at the societal level – against a municipal digital twin

The pitch points to a vision of a digital twin that represents parts of a municipal operation. The idea with the digital twin is that before implementing actual preventive measures, one can simulate the effects that interventions can have. A focus for teams during the hackathon can be to develop different concepts on how the twin can be designed, another focus can be to work with the challenge of obtaining data for a digital twin of this kind, a third focus can show what can be simulated through the twin.

6. Elin Glad and Christin Anderhov Eriksson, Östergötland Region. To create a sustainable change through visualization – that preventive project initiatives gain a foothold in daily operations

Preventing childhood obesity presupposes that changes and preventive interventions are part of the daily activities in, for example, municipalities. Region Östergötland points to the need for solutions that create sustainable changes – how can data-driven visualization be used for employees in municipalities to capture preventive interventions (preventive measures)?

7. Marija Simic, Karolinska Institutet. Digital coaching of parents from the generation “digital natives”

How, at the time of enrollment, can parents be supported through a digital coach (which is completely digital), possibly with an accompanying health check, to make healthy choices that counteract childhood obesity? Should mom and dad have different views on the digital coach? How is the coach made completely digital and in such a form that suits first-time parents who are “digital natives”; in other words, grew up in a time when smartphones, apps and seamless digitization are a natural part of everyday life.

8. Mariette Derwig, Region Skåne. New computer-driven, innovative ways to visualize the growth curve for children from birth to school start

How can data be used from birth onwards to visualize the weight development for the baby in connection with the follow-up checks at child welfare centres BVC? The target groups for an innovative data-driven visualization will be parents, nurses and doctors. The pitch provides concrete ideas on how the teams can take on the challenge, but also concrete hints on what to avoid.

There are several connections between this pitch and the pitch from HOBS.

9. Åsa Brugard Konde, Swedish Food Agency. The algorithm-driven keyhole machine [and the bonus “Keyhole Detective”]

When deciding which foods are to be keyhole-labelled (a Swedish label for healthy food) – how can we in a data-driven way and through an innovative algorithm identify and select which foods are to be keyhole-labelled? If it becomes easier for companies to find out which products can be keyhole-labelled, then the vision is for more keyhole-labelled foods to reach consumers! Can a gaming dimension be added so that you enable the children in the family to look for keyholes when the families shop – the “keyhole detective”?

About the Key hole label in English.

10. Elin Annwall, Generation Pep. A transparent data model for informative decisions on how to prevent childhood obesity?

How can a data model look like that collects data from different sources related to the prevention of childhood obesity (eg weight, activity level, geographical areas)? Based on this, how can transparent and open models be created that show differences between children from e.g. different areas and situations – can such a model form the basis for simulation and what can be done with such simulation power? The primary target group could, for example, be public health strategists at the municipal level.

There is a connection here between this need and the pitch made by Uppsala University about a digital twin of municipalities.

Questions and Answers (Q&A)

We who have an idea that we want to develop through the Hackathon – how do we know that the idea is suitable?

The hackathon is part of the Grand Challenge Prevent Childhood Obesity which is part of the project Prevention Childhood Obesity – for an equal health start in life. Prevention Childhood Obesity is a national initiative that aims to prevent overweight and obesity among children 0-6 years in Sweden and thereby contribute to reducing mental illness, development of type 2 diabetes and cardiovascular disease.

Feel free to watch the film

The solutions in the Hackathon can be directed towards the time of pregnancy, childbirth or the period from birth to the start of school. On this website, you will in January and onwards get more building blocks for your idea development.

The hackathon is a co-arrangement with SAS Global Hackathon – what does it mean?

SAS Global Hackathon has been arranging an annual Hackathon for a few years now to stimulate data-driven analysis and innovation. This year they have a track that focuses on Health. As part of this track, the prevention of childhood obesity is addressed. Through cooperation and co-arrangement, we help to organize the Hackathon during March and create conditions for good communication and exposure. SAS Institute is a project partner in the project Prevention Childhood Obesity – for an equal health start in life.

SAS Global Hackathon

What does it mean to register as a team?

If you as a team make a team registration, you register your interest in participating in the Hackathon. This does not mean that you are automatically in the Hackathon. To ensure that the concepts that emerge from the Hackathon address the period up to the start of primary school and to help you to develop new solutions, we make an assessment of the team applications. This can lead to you being given the task of adapting your description of ideas before the Hackathon.

The hackathon is a competition – what can you win?

We are not currently announcing a large sum of money as a win in the Hackathon. Instead, you compete as a team for the opportunities to

  • move on in the Grand Challenge to the next phase
  • get the honour of being appointed as the main solution from the Hackathon to prevent childhood obesity and give everyone an equal health start in life.

All teams also win the opportunity for individual feedback on the concepts from an expert jury, exposure of the teams in the organizers’ channels and participation in virtual events during the competition and at the final event. The prizes are described in more detail in the competition’s participant rules.

Hackathon and Grand Challenge – what is what, and how is it all connected?

The hackathon is part of the Grand Challenge Prevent Childhood Obesity. As part, Hackathonet aims to initiate the Grand Challenge and stimulate the development of good ideas into strong concepts. In later parts during the Grand Challenge, a selection of participating teams will have the opportunity to further develop and test their solutions. After that, a handful of teams will have the opportunity to prepare implementation and market implementation with the support of Sweden’s leading innovation business developers.

Who organizes Grand Challenge Prevent Childhood Obesity?

Grand Challenge Prevent Childhood Obesity is organized by the project Prevention Childhood Obesity – For an equal health start in life. The project is led by Swelife and includes 24 partners. The project is funded by the Swedish Innovation Agency Vinnova and the project partners.

The hackathon focuses from Idea to Concept – what does a Concept mean?

Through the Hackathon, we want to stimulate you as a team for a month to go from an idea to a compiled concept that constitutes an imaginary solution to a given problem for a certain situation. The current situation is that our children are living with obesity to a greater extent than before and that this has serious health consequences later in life.

In the work with your idea, you as a team will also be able to define the problem you are addressing and motivate the intended solution from several perspectives. Concept submission will take place through

  • movie (s)
  • textual / visual description (pitch).

The assessment criteria used during the Hackathon are described in more detail in the Rules for participation. Detailed instructions for submission can be found during the Hackathon.
