Plain English Summary
Background and study aims
Diabetes is a condition that causes a person’s blood sugar level to become too high. Insulin is the hormone made by beta-cells in the pancreas and controls the amount of glucose in the blood. In type 2 diabetes, the pancreas does not produce enough insulin or the person’s cells do not react to insulin. Educating type 2 (T2) diabetics to self-manage their own condition is currently recommend but isn’t widely implemented. Existing services focus on recommended population-based guidance and promote the idea that T2 diabetes is a lifelong and progressively worsening condition. In recent times, an improved understanding of the condition has revealed that it can be potentially reversed for many patients. In addition, there is a growing awareness of the need to promote preventive self-management as diabetes and cardiovascular disease have both become created an increasing burden on the health service. This study tests a program (intervention) that involves self-monitoring of blood glucose, energy restriction diets and self-management education to see if it improves the health of T2 diabetes patients .
Who can participate?
Adults aged 18-75 that have been diagnosed with T2 diabetes within the last year and have not been treated with drugs.
What does the study involve?
Participants are recruited to the study by Diabetes specialist nurses, from an existing Diabetes education course. They are asked to attend 6 weekly education sessions of 2-hours each. The course structure includes educational aspects of diabetes management and self-monitoring throughout but the 6-week period will be made up of three phases. In the first two weeks, data is collected from each participant, including information on general health and their health knowledge. In weeks 3-4, participants are asked to go on a 10 day energy restriction diet. The last two weeks focuses on the collection of data after the diet. Data is also collected from each participant every day. This includes
a single fasted fingerstick glucose test, body weight and % body fat from smart-scales that use simple bio-impedance body composition analysis once per day, keeping a hip-worn activity tracker with them all day and a dietary record of everything eaten and drunk each day. In addition, there are two self-administered oral glucose tolerance tests requiring 5 fingerstick results over two hours each time.
What are the possible benefits and risks of participating?
Potential benefits for participants include improved glucose tolerance through reduced visceral fat and enhanced insulin sensitivity, improved health literacy and self-efficacy.Ethical considerations are present around the safety of energy restriction diets. In this case a literature review has been conducted to identify risk areas and found risk to be highly unlikely over such a short time frame. The burden of data recording (daily dietary, blood glucose, body composition and activity data) will be minimized by using a web-based database that stores all information entered in a secure and private online space. Where possible automatic upload of results from measurement kit to database will be used. Specifically, the data from activity tracker, glucometer and body composition scales will automatically synchronise with a paired device (pairing is also automatic and so does not involve the user) to move data into the online record while dietary record will be manually entered into the same device and be transmitted in the same way. This transmission device is likely to be a user’s own smartphone or another mobile device (e.g. iPod Touch™) configured and provided by the study team. Fingerstick capillary glucose testing can cause pain, discomfort or the risk of infection. As well as all manufacturer instructions and guidance participants will be provided tuition in best practice for fingerstick based testing. Glucose tolerance tests carry a slight risk of reactive hypoglycemia for certain individuals. This risk is minimised by only conducting the tests when participants are not on low calorie diets and by providing guidance to eat breakfast as soon as the test is finished.

Type 2 diabetes mellitus
The proposed study intends to bring together diabetes self-management education aligned with current standards, personal data tracking of the components of the energy balance equation (weight, activity, diet) and glycaemic control (capillary blood glucose), online support/resources and a personalised short-duration energy restriction and transition diet to demonstrate the impact of behaviour on metabolism.
The potential participant will be introduced to the research and to the concepts of self-monitoring of blood glucose, energy restriction diets and self-management education.
Assuming the patient satisfies inclusion and exclusion criteria, then volunteers for the course and provides consent, they will receive an Introduction Pack to their home address in the post. This pack includes access details to online materials and details of course venue/dates/times and course structure and objectives.
Week 1: 2 hour session focused on introductory topics, includes completion of heiQ (health education impact questionnaire). Over the subsequent week participants begin collection and recording of diet, activity, body composition and blood glucose results including a 2-hour tolerance test from a fasted state on one morning before the next session
Week 2: 2 hour session focused on energy metabolism topics, food types, energy balance and planning energy restriction diet. Over the subsequent week participants maintain collection and recording of diet, activity, body composition and fasting glucose data and prepare to begin energy restriction diet on the day of the next session
Week 3: 2 hour session focused on review of baseline data and diabetes as a chronic condition including complications and recommended and best practice guidance. Over the subsequent week participants adhere to diet and continue collection of daily measures.
Week 4: 2 hour session focused on review of previous week, support with barriers to adherence and planning of transition diet. Over the subsequent week participants maintain data collection and begin increasing dietary amount in the 4 days leading up to the next session
Week 5: 2 hour session focused on review of course and personal learning objectives, goal setting and planning to maintain energy balance. Over the subsequent week participants maintain data collection including a 2-hour tolerance test from a fasted state on one morning before the next session
Week 6: 2 hour session focused on review of post-diet data and collection of feedback/input from participants and educators on the course content and acceptability, includes completion of follow-up heiQ.
Personal data and educational resources (online) will continue to be available to participants for at least 4 weeks after completion of the course at week 6.
