Scientific title	Walking away from type 2 diabetes: a cluster-randomised controlled trial to investigate the effect of structured education on walking activity in those with a high risk of developing type 2 diabetes
Study objectives	A pragmatic structured education programme aimed at promoting walking activity initiates long-term increases in physical activity in individuals identified through a risk score as having an increased risk of developing type 2 diabetes.
Ethics approval(s)	Nottingham Research Ethics Committee 2, 02/03/2009, ref: 09/H0408/32. A substantial amendment (1.0) was approved on the 21/05/2009 and a second amendment (2.0) is pending as of 17/07/2009
Health condition(s) or problem(s) studied	Diabetes
Intervention	Experimental arm (lifestyle counselling): The lifestyle counselling (a group-based structured educational programme to promote physical activity) in the experimental arm is 3.5 - 4 hours at baseline. All individuals will be invited to attend annual group-based sessions (of the education programme) during the trial period. These follow-up programmes will be designed to help participants interpret and analyse their annual biochemical and anthropometric follow-up data, review progress and goals and respond to issues, queries and barriers; the main objectives of the programme will also be reinforced. Each follow-up programme will last two hours and will be conducted after the participant's annual clinical measurement session. All participants will also receive telephone contact at 6 months after the initial educational programme and at 6 months after each annual follow-up session where motivational interviewing techniques will be employed to review progress. Control arm: Written information (booklet) on risk factors for type 2 diabetes and cardiovascular disease (CVD) and how physical activity can be used to prevent these conditions. Follow-up measurement sessions will be conducted at 12, 24 and 36 months (for both intervention arms).
Intervention type	Other
Primary outcome measure	Change in ambulatory activity (walking); measured at 0, 12, 24 and 36 months using: 1. A uniaxial accelerometer 2. International Physical Activity Questionnaire (IPAQ)
Secondary outcome measures	Measured at 0, 12, 24 and 36 months: 1. Light-, moderate- and vigorous-intensity physical activity, measured using a uniaxial accelerometer 2. Time spent in sedentary activities assessed by International Physical Activity Questionnaire (IPAQ) 3. Fasting and 2-hour post-challenge plasma glucose, measured by venous sampling 4. Glycosylated haemoglobin (HbA1c), measured by venous sampling 5. Advanced glycation end products, measured by a dermal spectroscopic measurement technique (SAGE, VeraLight, USA) 6. Fasting and 2-hour post-challange plasma insulin, measured by venous sampling 7. Adipokines (leptin, interleukin 6 and tumour necrosis factor alpha), measured by venous sampling 8. C-reactive protein, measured by venous sampling 9. Standard anthropometric variables (including weight, body mass index [BMI], body fat %, waist circumference) 10. Visceral adiposity (sub-set of participants), measured by single section abdominal magnetic resonance imaging (MRI) scan 11. Muscle mass (sub-set of participants), measured by whole body dual energy X-ray absorptiometry (DEXA) scan 12. Illness perceptions and efficacy beliefs, measured using the Brief Illness Perceptions Questionnaire and 100% Confidence Rating scale (exercise self-efficacy) 13. Health related quality of life, measured using the EQ-5D 14. Depression, measured using the Hospital Anxiety and Depression Scale (HADS)
