The study, published in scientific journal Gut and led by Dr Charlie Lees and Dr Gareth-Rhys Jones, found that Crohn’s affects 284 people out of every 100,000 in Edinburgh, and Colitis affects 432 people out of every 100,000.
The team use data from primary and secondary care, as well as a paediatric registry to conduct their research and health records to confirm their findings.
The figure is significantly higher than the 1 in 210 people said to be living with Crohn’s and Colitis in the UK, although there is growing evidence that this figure has changed in recent years.
Dr Charlie Lees, a consultant gastroenterologist in the Edinburgh IBD Unit, added: “There is no doubt that IBD is now becoming a global pandemic, with Crohn's Disease and Ulcerative Colitis more common across the world. This work shows just how big the problem has become, not just in Edinburgh, but across much of the western world. This study provides much-needed data and can act as a launchpad for pivotal new studies to help patients.”
Sarah Sleet, CEO of Crohn’s & Colitis UK, said: “This important study contributes to the growing evidence that the prevalence of IBD is significantly higher than currently recognised. Crohn’s and Colitis are a hidden and growing health crisis and the number of people living with the conditions is huge. Crohn’s & Colitis UK are currently undertaking a prevalence study and we are looking forward to seeing how UK wide results compare to the Edinburgh wide results in this research next year. These shocking higher figures must influence decision making in the NHS, and push forward the case for increased resources, improvements to IBD services and ultimately better care for people with Crohn’s and Colitis.”
