A leading paediatric gastroenterologist is investigating whether reduced vitamin D levels are to blame for New Zealand's high incidence of inflammatory bowel disease (IBD) cases.
Professor Andrew Day of the University of Otago, Christchurch, was last year appointed Cure Kids' Chair of Paediatric Research and is heading up a comprehensive programme of research into the disease in children and adolescents.
An umbrella term describing a range of chronic conditions affecting the gut, IBD affects one in every 227 people in New Zealand, with children in the South Island at substantially higher risk than their North Island counterparts.
It's thought the higher rates in South Island children are potentially due to variations in sunlight, which in turn affect people's vitamin D levels.
Professor Day's research aims to understand whether increased vitamin D leads to lower levels of inflammation.
