Dutch students developed a lesson program regarding the myBigO app

Dutch students developed a lesson program regarding the myBigO app

Hello, we are five students (Dries, Naomi, Lisanne, Marije en Tessa) from Het Streek Bovenbuurtweg (Ede, The Netherlands). We are in our fourth year of pre-university education. For our O&O class we were given the assignment to put together a lesson program consisting of two lessons, based on the BigO-app. We had to give those lessons to several students. Monica Mars and Desiree Lucassen, experts in the field of measuring behavior through apps, gave this assignment to us. O&O is a subject in our school. It stands for ‘Onderzoeken en Ontwerpen’, which means Research and Design. We receive various assignments throughout the year, including this project.

In the first lesson, the students were told about a healthy eating and living environment. In the first lesson we also analysed by a kahoot how healthy the students were already living. We explained how the BigO-app itself works, and we asked the students to use this app for a week. We analysed the data they had collected. Our conclusions and observations were shared with the students in the second lesson. Two of the students had even earned a medal because they had made the most pictures.

We were very pleased with this project and we had a great deal of fun giving the lessons to the students. When the students ate and how much they ate resulted in a clear graph. In the second lesson we were able to talk about the results of the graph. The students were confronted with the fact that most of the non-healthy advertisements came from their own school. Mrs. Mars explained she can make good use of our results; we were glad to hear that!

We learned a lot because of this project. We did our own research so we could give interesting and useful lessons. A lot of research was necessary to properly understand the project, so we did research on a healthy living environment and we also did some research on the BigO-app. This came in very useful further in the project. Lastly, we gained more experience by the teaching itself.

The BigO team analyse data collected from citizen scientists via the BigO app

Following the successful deployment of the first live-version of the data collection app, BigO scientists have started looking at real data in an effort to evaluate the data collection system and the ensuing analysis. BigO aims collect data from ‘citizen scientists’ to make estimations about the behaviours of children and teenagers, always in connection with their living environment. BigO will then use this information to inform government policy and develop effective interventions to manage and prevent childhood obesity. From March to June this year, students from three schools—two in Greece and one in Sweden— have been using the newly developed BigO app to anonymously upload various aspects of their lifestyles. As citizen scientists, the students report the food they eat, record their physical activity levels and map the food advertising encountered in their everyday life. Based on the data collected to date, the BigO team are modifying data collection processes and streamlining the analytical abilities of the system in preparation for larger scale data collection in 2019.

UCD initiates Delphi Panel study to establish key indicators for monitoring and evaluating childhood obesity

UCD initiates Delphi Panel study to establish key indicators for monitoring and evaluating childhood obesity

BigO consortium partner, University College Dublin (UCD), is working to engage with leading public health authorities throughout Europe to co-develop a technological system that would be useful to public health authorities for monitoring childhood obesity and evaluating population-level prevention/treatment approaches.

To achieve this, they are carrying out a Delphi Panel study with experts in the field of public health to establish the key indicators or measures that are a priority for the monitoring and evaluation of childhood obesity over the next 5 – 10 years across Europe. This panel of experts will consist of 10-15 individuals who have a direct influence over the development and implementation of policies aimed at reducing childhood obesity in BigO participating countries ( Sweden, Greece, Ireland, The Netherlands, Spain).

The information gathered as a result of this study will go on directly to inform the parameters of the BigO data monitoring system which will be initially rolled out in Sweden, Greece, Ireland and The Netherlands and then later across Europe.

Afterwards the students analysed the collected pictures in order to quantify the types of advertisements per region. The students focused on the percentage of food advertisements in relation to the total number of advertisements, in each of these areas.

Pre-pilot confirms operability of data collection technology

Pre-pilot confirms operability of data collection technology

Students aged 15-16 at the IEGS high school in Stockholm have, since November 14th, been using the BigO app to photograph and upload food advertisements that they encounter in their everyday life.

As of December 8th, a total of 367 images have been uploaded and the collection points can be viewed on the community portal (http://gateway.mysphera.com:28080/dist/#/map).

Reports are that some 80% of the uploaded pictures are classified as valid data collection points, and that no app glitches have been observed.

The next test will involve some 25 students from the same high school, designated to map all the advertisements in certain geographical regions, with the students acting as “scientists”. The 3 regions of Stockholm that have been selected represent areas with significantly different socioeconomic characteristics and also significantly different overweight and obesity prevalence.

The projected dates for data collection would be December 13-14-15 and the data analysis will be carried out December 18-19.

“This type of deployment could be the basis of a very focused use case for the public health authorities, and the collected data will help to initiate the development of the BigO analytics  too.”, says Pre-Pilot Coordinator in Sweden, Dr. Ioannis Ioakeimidis

First students in The Netherlands have been acting as citizen scientists

First students in The Netherlands have been acting as citizen scientists

On Friday November 24th, five young citizen scientists (12-14 years old) have participated in a pilot in the Netherlands. During 45 minutes they captured food advertisements in shopping area of the city centre of Ede (~112,000 inhabitants, 318.6 km²). The purpose was to see whether children can help us in collecting data on their own food environment, but more importantly how we can intrinsically motivate them to be engaged in these type of projects.

The children walked around in two teams in the shopping area, with the mission to locate as many food advertisements as possible within the given time. To this aim they used a demonstration version of the BigO app, containing only the functionality to locate were pictures are taken. After the pilot study, the children filled out questionnaires about the application and the project.

The children, all students from the local Technasium school “Het Streek”, were very enthusiastic on being citizen scientists and were surprised about the number of food advertisements in their surroundings. In total they located about 60 food advertisements in an area of 0.3 km2. The students came up with good suggestions for the researchers on how to proceed with the project.

BigO has been presented at the AGORA meeting in Warnsveld (NL)

On November 14th The BigO project has been presented during the symposium that was held on the occasion of the anniversary of AGORA in Warnsveld, the Netherlands. AGORA is a research alliance between the regional municipal health agency (GGD Zuid-Oost Nederland) and Wageningen University that was founded in 2005. AGORA is Greek for market place; the alliance is founded to strengthen connections between academia and practice; it is a marketplace were applied and fundamental researchers can find mutual research interest and start research projects.

 

During the symposium a diverse group of health policy advisors, epidemiologists and researchers were discussing actual issues on health policy, such as childhood obesity and care of elderly. One of the discussions was on the public space and how this may affect health related behaviour. The citizen scientist and big data approach of BigO was introduced as a novel and research methodology concept to collect information on local environmental risk factors and health related behaviour, such as diet and physical activity. During the meeting contact has been made between local health policy advisors, and opportunities for cooperation were explored.

Swedish National Food Agency hosts BigO meeting in Uppsala, Sweden 18 Sep

Swedish National Food Agency hosts BigO meeting in Uppsala, Sweden 18 Sep

BigO consortium partners gathered for a fact-finding meeting in Uppsala at the behest of the NFA, to establish what information produced by BigO is desired by public health authorities to complement or enhance their own knowledge bases. Along with NFA, Karolinska Institutet, Wageningen University (NL), University College of Dublin (IRL) and Temple Street Children’s Hospital (IRL) participated in the event that saw the Public Health Agency of Sweden as the sounding board for the discussion.

In addition to BigO data being able to complement public health authorities’ own data collection and analysis, cross-country data comparisons were found to be a relevant study topic for public health authorities. The disparities between different national and local communities and makes it possible to adapt, use and deploy a variety of strategies depending on the circumstances.

The ambition of BigO is to – through the use of Big Data – describe the background and outcome of community behaviour regarding physical activity and eating patterns, to aid public health authorities deploy efficient strategies.
