Background and study aims
Type 2 diabetes is a metabolic disease characterised by high blood sugar which over time may lead to complications which impair quality of life and reduce life expectancy. Despite its small size, the proportion of the population in Bahrain which is affected by type 2 diabetes is one of the highest in the world. The risk of developing this disease is increased if an individual is obese and/or physically inactive, and it is anticipated that cases of type 2 diabetes in Bahrain will continue to rise due to the high proportion of the population affected by these two conditions. High levels of physical activity such as walking are known to improve control of blood sugar and to reduce the risk of complications from types 2 diabetes. However, many diabetic patients are not active enough. Furthermore, there is still debate about the best approach to deliver or supervise walking programmes for these patients. The aim of this study is to test the procedures that will be used in a larger study to find out about the health benefits of a community-based walking programme for Bahraini adults with type 2 diabetes.
Who can participate?
Bahraini adults aged 24-60 with type 2 diabetes.
What does the study involve?
Participants will be randomly allocated to one of three treatments: standard diabetes treatment alone; standard diabetes treatment with physical activity education to promote walking; or standard treatment with physical activity education to promote walking and a step counter to record daily walking activity. Patients will have their blood glucose, physical activity level, fitness and body composition assessed at the start, middle (6 weeks) and end (12 weeks) of the study.
What are the possible benefits and risks of participating?
The investigators believe that the risks to the participants are minimal.
Where is the study run from?
Arabian Gulf University (Bahrain).
When is the study starting and how long is it expected to run for?
From January 2011 to February 2012.
Who is funding the study?
Arabian Gulf University and Ahlia University, Manama, Kingdom of Bahrain.

| Scientific title | Efficacy of a COMmunity-based WALKing programme with or without a pedometer on markers of glucose control, cardio-respiratory fitness and lung inflammation in Bahraini adults with type 2 diabetes: a pilot randomised controlled trial |
| Study acronym | COMWALK2 |
| Study objectives | The aim of this pilot study is to test the robustness of the protocol and of the study methodologies prior to conducting the study on a larger group of patients. The main objectives of the pilot study are: 1. To test the integrity of the study protocol including inclusion/exclusion criteria, the randomisation process, storage and testing of equipment and materials, and training of staff in administration and assessment procedures. 2. To obtain initial data for the primary outcome measure haemoglobin A1c, in order to perform a sample size calculation for the main study. 3. To determine compliance with and acceptability of the exercise intervention by patients. 4. To test that the self-assessment questionnaires, information documents and consent forms are comprehensible and appropriate. |

| Health condition(s) or problem(s) studied | Type 2 diabetes |
| Intervention | Following baseline measurements, patients will be randomly assigned to one of three groups (n=15 each): 1. Standard diabetes treatment alone (i.e. control) 2. Standard treatment and two one-hour sessions of group-based physical activity education, each delivered at six week intervals, to promote walking 3. Standard treatment, a pedometer and two one-hour sessions of group-based physical activity education, each delivered at six week intervals, to promote steps-per-day goals.
