Brief Summary

This study evaluates the effect of changes in the range of drinks offered in vending machines in schools on the sugar intake of pupils via drinks.

Detailed Description

Children and adolescents consume a considerable amount of liquid in the form of sugary drinks. A high sugar diet associated not only with the increase in overweight children, but also with type II diabetes, cardiovascular disease and cancer.

In many schools, cold drink vending machines with different fillings are available offering various sugary drinks.

Participating schools will be randomised in a ratio of 1:1:1 into three groups. In one intervention group, the vending machines will be re-equipped to contain 60% drinks containing a maximum of 6.7g sugar/100ml, 20% drinks containing more than 6.7g sugar/100ml and 20% water. In the second intervention group, the vending machines offer 80% water, 20% products with a maximum of 6.7g sugar/100ml. In the control group, the range of products offered by the vending machines remains unchanged. Information of the students drinking habits, total fluid intake and sugar intake in the form of food and drinks will be collected. In addition, data such as body height, body weight, physical activity and socio-democratic or socio-economic data will be accumulated. The sales figures of the drinks in the vending machines will be recorded and information about the surroundings of the schools (fast food chains, supermarkets, etc.) will be collected.

The survey of students and data collection will be repeated three times. In a sub-study, demographic data and the frequency of consumption of sugared beverages and water are collected from 2 focus groups. In addition, participants will complete a questionnaire on general attitudes towards sugary drinks or water, obstacles to and incentives for reducing sugar consumption by liquids or increasing water consumption.
