Background and study aims. People in the UK consume far too much sugar, exceeding recommendations, with the largest source in the diet being sugar-sweetened beverages (SSBs). SSB consumption has been linked with health problems, including the development of obesity (being very overweight), metabolic syndrome (where someone is obese, has diabetes and high blood pressure), diabetes, and dental disease. It also contributes to health inequalities given that people who are more socially deprived consume more SSBs. One possible way of reducing SSB consumption is to reduce the sizes of the containers (i.e. bottles and cans) in which these drinks are available. However, there is currently no evidence that this would reduce SSB consumption. We want to run a trial see whether placing a fixed volume of SSBs in smaller bottle sizes reduces consumption at home. To finalise the design of this trial, we are running a preliminary study to assess the feasibility and acceptability of the trial procedures. Who can participate? Households (defined as people who live together, who may or may not be related but who share all or most drink and food within the house) that buy at least 2 litres of week of regular (i.e. not diet or low sugar) cola drinks and live in Cambridge, UK. We will recruit one individual from each eligible household to act as a household representative, who will consent to participation in the study on behalf of all household members and provide all necessary data. What does the study involve? Each week, for four weeks, the research team give each participating household a set amount of a carbonated cola drink based on how much cola they typically buy in a week. The total amount of cola is split into bottles of one of four sizes: 1500ml, 1000ml, 500ml or 250ml. All the cola delivered in a week to particular household is in the same sized bottle. Each household is also given their cola in each of the four bottle sizes over the 4 week period of the trial. What are the possible benefits and risks of participating? We consider this study to be low risk. We do not expect any adverse consequences associated with taking part in the study. The findings from this preliminary study will help us to design of a trial to test whether giving a fixed amount of SSBs in smaller bottle sizes reduces consumption at home. The results from this trial are expected to contribute to ongoing scientific and policy discussions about effective methods for reducing sugar intake in the general population. Where is the study run from? The study is run from the Behaviour and Health Research Unit at the University of Cambridge (UK) When is the study starting and how long is it expected to run for? May 2015 to June 2016 Who is funding the study? Department of Health Policy Research Programme (Policy Research Unit in Behaviour and Health [PR-UN-0409-10109]) Who is the main contact? Professor Theresa Marteau [email protected]
