Aims: Studies have shown that progression to Type 2 diabetes can be delayed and/or prevented by lifestyle modification in people with IGT. The Greater Manchester Collaboration for Leadership in Applied Health Research and Care (CLAHRC) has been working with NHS Bolton to implement and evaluate a primary care based, preventative lifestyle change programme.

Methods: The local health trainer (HT) service, offering lifestyle support over a period of six months, was diversified to offer support to people with IGT. Eligible patients were referred by GPs or practice nurses to see the HT based at the surgery. Glucose levels were measured at baseline, at the end of the six month intervention and one year after completion of the programme, making use of data routinely collected in primary care.

Results: A total of 134 participants were included in the initial evaluation with an average body mass index of 31.8kg/m2; however, we only report here on the 80 with a confirmed IGT diagnosis with a recent 2h oral glucose tolerance test between 7.8 and 11mmol/l. One year after completing the HT programme, among 80 people with IGT at outset, 21.3% (n = 17) successfully reverted to normoglycaemic levels, 32.5% (n = 26) still had IGT and 21.3% (n = 17) progressed to Type 2 diabetes. No follow-up data were available for 25.0% (n = 20).

Conclusions: Outcome data suggest that patient outcomes are comparable to published studies and indicate that the local health economy and patients are benefiting from the HT service offered to people at risk of developing Type 2 diabetes.
