PREdiCCt: The Prognostic effect of Environmental factors in Crohn’s and Colitis.

The PREdiCCt study, based at the University of Edinburgh, is the first of its kind and aims to increase the understanding of how diet, lifestyle and the bacteria in your gut influence flare and recovery in Crohn’s Disease and Ulcerative Colitis.

The study recruited 2629 participants from 49 hospitals across the UK. Over two years they followed the participants and collected information on the food they eat, their lifestyle and their gut bacteria. This was done through an environmental questionnaire, food frequency questionnaire, stool sample, and saliva sample.

If someone experienced a flare, another stool sample was collected, aiming to see how the environmental and microorganism factors recorded at the beginning differ for those that flare up versus those that don’t. The study is now in its final phase of analysing the data collected.
