Background and Objectives: Diabetes is complex, chronic illness requiring comprehensive risk-reduction strategy including community efforts. While Korea society is getting older and prevalence of diabetes is getting high, control rate of diabetes among treated patients is still low in Korea. Gyeonggi province, the largest province in Korea, developed the network of 37 community-based education centers for diabetes self-management (NCECD). NCECD incorporated community public health centers, diabetes education centers and primary medical clinics to improve knowledge, self-efficacy and self-management among diabetes patients in Gyeonggi province, Korea. Methods: Standardized education and counseling program has been implemented to about 2,000 diabetes patients during 4 weeks period in 37 cities, Gyeonggi province in 2018. Standardized questionnaire was distributed to participants before and after programs to find out changes of` diabetes knowledge, self-efficacy and self-management of diabetes. Results: 1,794 people were answered before and after programs and significant changes were seen for diabetes knowledge, self-efficacy and self-management. An average correct answer rate of diabetes knowledge was increased from 76.0% to 88.6%. Mean of diabetes knowledge increased from 7.9 to 8.7 (p=0.000) and the overall assessment of participants’ self-efficacy was increased in mean score from 16.1 to 17.4(p=0.000). Their ability to perform diabetes self-management increased in mean score from 3.4 to 3.7 (p=0.000). Conclusions: These findings demonstrate that the network of thirty-seven community-based education centers for diabetes self-management can be successful in Gyeonggi province, Korea and important insight is provided for ways that network can be tailored to meet the needs of their populations.
