Type 2 diabetes is a serious health condition that affects many older adults from ethnic minority communities in Northern Thailand. These populations, often referred to as hill tribes, include groups such as Akha, Lahu, Hmong, and Lisu who live in remote mountainous areas of Chiang Rai Province. Previous research has found that the prevalence of type 2 diabetes among ethnic minority elderly in Thailand is 16.8%, which is higher than the general Thai population. Many of these individuals have difficulty managing their diabetes because of low literacy, limited access to healthcare, language barriers, and poverty.
The purpose of this study was to test whether a structured Diabetes Self-Management (DSM) program could help ethnic minority older adults (aged 60 years or older) improve their blood sugar control, increase their ability to manage diabetes on their own, and reduce emotional distress related to diabetes.
This study used a cluster randomized controlled trial design. Villages in Chiang Rai Province were randomly assigned to either the DSM intervention group or the usual care group. A total of 108 participants (54 per group) were enrolled. Participants in the intervention group attended a 6-week education program with weekly interactive sessions covering diabetes knowledge, healthy eating, physical activity, medication management, problem solving, risk reduction, and emotional coping. Two home visits were also provided at Weeks 8 and 10. Participants in the usual care group received standard brief discharge education and routine follow-up visits.
The main outcome measured was the change in HbA1c (a blood test that shows average blood sugar levels over the past 2 to 3 months) from the start of the study to 12 weeks later. Additional outcomes included changes in diabetes self-management behaviors and diabetes-related psychological distress, measured using validated questionnaires.
