The investigators hypothesize that a training course to people with diabetes on peer support and empowerment will improve their glycemic parameters, knowledge on diabetes and level of self efficacy. This group of trained patients (peer leaders) should be competent to teach and help other patients with diabetes through peer support and empowerment on better self management of their diabetes.

In our attempt to improve diabetes self care, one important component is the diabetes patients who should have the best incentive to improve their care levels and reduce their complication risk, provided that they are appropriately trained, informed, educated and supported. According to the World Health Organization (WHO) Innovative Care for Chronic Conditions framework, expert patients are recommended to be included in the health care team to make them prepared, motivated and informed decision makers to preserve health and improve clinical outcomes. In a recent report on WHO consultation, peer support interventions are considered to have enormous potentials to make self management an effective component of chronic care.

Peer support is defined as support from a person who has experiential knowledge of a specific behavior or stressor and similar characteristics as the target population. Thus people with common illness experience can share knowledge and experience in a less hierarchical and reciprocal relationship compared to that between patients and health care professionals. A number of programs including health worker-led groups with peer exchange, peer-led face-to-face self management programs, peer coaches and remote peer support have reported encouraging results with short term improvement in metabolic or cognitive-psychological-behavioral dimensions, although these results are often limited by non-sustainability of changes and insufficient reach or adoption of programs by patients or health care workers. In the WHO report, health care experts from various disciplines concluded that whilst peer support is a promising approach for diabetes management, issues regarding methods of organization, types of programs and their integration with other clinical and outreach services remain to be addressed. Of note, there is a paucity of similar data in developing and low income areas which are hit hardest by this epidemic and where peer support program may offer great promise to make diabetes prevention and care program more sustainable and accessible, if implemented and evaluated systematically.

Health professionals, especially diabetes nursing specialists, have been training diabetes patients on the understanding and self-caring of diabetes. However, with the emerging concept and preliminary evidence of success in the role of "peer advisors" in diabetes to lead self care courses for other fellow patients, a train-the-trainer program to develop "expert patients" is essential. On top of factual knowledge on diabetes as a disease, context of this program needs to cover include communication and empowerment skill, basic knowledge on psychology, stress management, social support, empowerment, healthy lifestyle including diet and physical activity.

In the evaluation of the programs, there is a need to define the qualities and roles of the peer supporter, design programs which integrate and complement formal health services, identify optimal mix of modalities of intervention, types and dose response of these interventions and evaluate acceptability and effectiveness of these programs in different cultures. Other evaluation indexes include effects of programs on behavioral changes, knowledge and attitudes, functionality, clinical care as well as their cost effectiveness, reach, implementation-consistency, adoption and maintenance of effects over time.
