Young people with a fizzy drink

Supporting young people to rethink sugary drinks

Ahead of No Fizz February, researchers at Queen Mary University of London have been looking at how they can tackle sugary drink consumption among local young people.

High childhood obesity and tooth decay rates in East London 

East London has some of the highest childhood obesity and tooth decay rates in the country. Sugary drinks are a major contributor to both unhealthy weight gain and tooth decay. 

That’s why we funded this study – which aims to reduce sugary drink consumption in 12- to 13-year-olds, right at the age where habits become ingrained. 

Co-designing an intervention with teachers and young people to reduce sugary drinks 

The research project, led by Professor Huda Yusuf, ran a feasibility study, testing whether schools could help young people cut down on sugary drinks. They worked with two secondary schools in East London. 

The intervention, which was delivered to 240 young people, aimed to reduce sugary drinks consumption and was co-designed with young people and teachers. It included: 

  • A mobile app (DISS DASH) for young people 
  • Resources to help parents support healthier choices at home 
  • Teacher training in Group Motivational Interviewing

About DISS DASH the app 

DISS DASH is a platform game where players navigate different environments, aiming to beat their highest scores and compete with friends on the leaderboard. Along the way players can access educational content focused on healthy living and reducing sugary drink intake. 

Findings from the study 

Teachers and pupils who took part valued the intervention. Young people said that: 

  • They felt comfortable talking openly with teachers 
  • They liked being listened to 
  • The sessions were useful and collaborative 

One student said: “I learnt from you in terms of having that healthy diet and regular physical activity.” 

A teacher said: “I think it’s the right setting because… you’ve got a massive cohort of kids there that you can gain access to.” 

Students felt that their health-related behaviors could be modified by highlighting risks and providing goals.  

“Barts Charity has been instrumental in funding this local study to improve health outcomes for children and young people and the co-developed resources will be shared with schools and young people to enable healthy behaviours among our communities in East London.”

Next steps 

The findings suggest that the approach could be effective, although there were challenges in recruiting secondary schools. Professor Huda Yusuf and her team are now drafting publications, sharing resources with local authorities in North East London, and exploring future research avenues – including whether this would work better in primary schools.
