A strong evidence base
Rigorous ongoing scientific research and evaluation underpins all of MEND’s work.
We are proud to have a 20-year research partnership with the UK’s most eminent child health organisations, Great Ormond Street Hospital for Children NHS Trust and University College London Institute of Child Health

The MEND Programmeis the first clinically proven community-based UK child weight management programme to operate in a scalable and cost-effective manner. It is supported by very successful research to date, including a feasibility study, pilot and Randomised Controlled Trial (RCT) – gold standard clinical research. We also have rollout results quantifying the health and social outcomes of the MEND Programme at over 300 sites in the UK, Denmark and Australia.
Our evidence shows that the MEND Programme helps children lose weight (specifically body fat), increases their physical activity levels and self esteem and reduces their sedentary behaviours e.g. screen time. These results continue to improve over time after the end of the core Programme. Children demonstrate sustained positive health improvements 12 months after starting the MEND Programme. We are now conducting a second, larger RCT at the Institute of Child Health to follow families for longer periods to see how they are faring 2, 5 and 10 years after starting the Programme.
Our work in Denmark and Australia has demonstrated that the Programme is effective in other countries and languages. As we expand internationally, we will be extending our research work with other respected academic partners.
