Diabetes screening on offer to Norfolk residents
As a new report highlights the fact that levels of Type 2 diabetes in the UK have doubled in recent years, Norwich-based resarchers are offering a screening test for the condition.
The screening test for Type 2 diabetes comes as a new report published in the Journal of Epidemiology and Community Health discloses that from 1997 to 2003 there was a 74% rise in new cases of diabetes in the UK.
By 2005, more than 4% of the population was classed as having diabetes – nearly double the rate of 10 years earlier. The bulk of cases are Type 2 diabetes.
In a first for the UK, a two-year research programme is running to screen 6,000 volunteers living in North, Central and South Norfolk. Study participants undergo a simple blood test to check the level of glucose in their blood.
Higher than normal glucose (known as Impaired Fasting Glucose or IFG) could mean they are in a “pre-diabetes” phase and are more likely to develop Type 2 Diabetes.
Study chief investigator Professor Mike Sampson said: “We are all being asked to think about living healthier lives and the UEA-IFG study gives local people an excellent opportunity to see if they may be at risk of Type 2 Diabetes”.
The research programme, known as the UEA-IFG Study, is being delivered by multi-professional teams from the Norfolk and Norwich University Hospital, and UEA.
How the UEA-IFG study works:
People living in north, central and south Norfolk and who are at risk of Type 2 Diabetes can volunteer for the screening programme. At risk means aged between 45-70 with one or more of the the following: a BMI greater than 25, an immediate family member with a history of diabetes, a history of coronary disease or had diabetes during pregnancy.
Volunteers make an appointment to undergo a simple fasting blood test and some base line measurements (height, weight etc) at the Clinical Research and Trials Unit at UEA in Norwich.
All participants will receive their results by letter and most are expected to have normal blood glucose. Researchers expect that 11 per cent will be in the “pre-diabetes” phase and three per cent will be newly diagnosed with Type 2 Diabetes.
If found to be in the pre-diabetes phase or newly diagnosed with Type 2 Diabetes, a repeat test will be done to confirm the first set of results they will be asked by a Diabetes Prevention Facilitator, a senior nurse, dietitian or nutrition scientist, if they want to take part in the lifestyle intervention.
Volunteers will then be randomly allocated to a control group, who will receive a one off education session, or an intervention group where the aim will be for people to achieve seven per cent weight loss through a better diet and increasing physical activity levels. These volunteers will receive education from healthcare professionals to help improve diet and exercise levels in order to see if preventative changes to their lifestyle can help reduce the risk of them developing Type 2 Diabetes.
The role of the volunteer mentors who have Type 2 Diabetes will be to encourage and support study participants through the programme and to maintain diet and exercise targets.
Diabetes is one of the biggest public health challenges facing the country and in England it is estimated 2 million people have the condition. About 80% of those with diabetes in England have Type 2 Diabetes. In Norfolk there are about 30,000 people with Diabetes and about 2,500 are newly diagnosed each year.
Type 2 Diabetes is most commonly diagnosed in adults over the age of 40, although increasingly it is appearing in young people and young adults. Glucose builds up in the blood, as in people with Type 1 Diabetes, but symptoms appear more gradually and the diabetes may not be diagnosed for some years.
