Dr Ffion Curtis, a new member of HART, recently presented a poster at the Diabetes UK Conference. Ffion’s work, in collaboration with colleagues, examined associations between vitamin D status and measures of glycaemia in participants with normoglycaemia, impaired fasting glucose and Type 2 diabetes (Curtis, Rice, Thatcher, Davison). A seasonal variation in vitamin D status was identified in participants with varying levels of glucose control. Participants with lower vitamin D had poor glucose control compared to those with higher vitamin D concentrations on the day of testing and at 12 months follow-up. Whilst further studies are required to determine cause and effect, these findings may provide additional evidence of a protective effect of vitamin D in relation to glycaemic control and the development of Type 2 diabetes.
