Abstract
BackgroundBenefits of physical activity in the management of diabetes are well documented. However, evidence on the effectiveness of interventions integrating physical activity in diabetes care is sparse especially in the countries of the Gulf Cooperation Council. The results from this study will increase our understanding of the use of multi-component interventions aimed at increasing physical activity levels in inactive adults with type 2 diabetes in primary health care in Oman.Methods/designThe study is a one year 1:1 cluster randomized controlled trial of the MOVEdiabetes programme (intervention) versus usual care in eight primary health care centres in Oman. The MOVEdiabetes programme utilizes face to face physical activity consultations promoting 150 min of moderate to vigorous physical activity per week (≥600MET-mins/week), pedometers to self-monitor step counts and monthly telephone WhatsApp messages for follow up support. Inactive adults with type 2 diabetes and no contraindication to physical activity will be recruited over a two months period, and followed up for 12 months. To demonstrate a 50% between group difference in physical activity levels (MET-mins/week) over 12 months, (at a power of 80%, and significance level of 5%), 128 participants would be required to complete the study (64 in each arm). Based on a drop-out rate of 20%, 154 participants would require to be recruited (77 in each arm). Assuming a recruitment rate of 70%, 220 potential eligible participants would need to be approached. The primary outcome is change in levels of physical activity measured by the Global Physical Activity Questionnaire. In addition, accelerometers will be used in a sub group to objectively assess physical activity. Secondary outcomes include changes in metabolic and cardiovascular biomarkers, change in self-reported health, social support, self-efficacy for physical activity, and perceived acceptability of the program. All intervention delivery and support costs will be monitored.DiscussionThis study will contribute to the evidence on the feasibility, cultural acceptability and efficacy of interventional approaches for increasing physical activity in primary care for persons with type 2 diabetes in Oman.Trial registrationInternational Standard Randomised Controlled Trials No: ISRCTN14425284.

The International Diabetes Federation (IDF) estimates that 8.3% of people globally have diabetes (382 million), 90% of which is type 2 diabetes (T2D) and the numbers affected are expected to increase by 55% by 2035 [1]
Summary
Benefits of physical activity in the management of diabetes are well documented. Evidence on the effectiveness of interventions integrating physical activity in diabetes care is sparse especially in the countries of the Gulf Cooperation Council. The results from this study will increase our understanding of the use of multi-component interventions aimed at increasing physical activity levels in inactive adults with type 2 diabetes in primary health care in Oman. Similar to the other high income countries of the Gulf Cooperation Council (GCC) [3], has gone through rapid economic development leading to high energy dense diets and sedentary lifestyles [4]. Oman and other GCC countries are facing similar challenges related to management of diabetes and the IDF has estimated that the MENA will have a 96% increase in the number of people with diabetes by 2035 [1, 6]. Meeting physical activity recommendations has been shown to increase insulin sensitivity, lower blood sugar levels, reduce body fat and improve physical condition [9]
