Abstract
Diabetes mellitus is a chronic disease and a major health problem in Thailand. The objective 
 of this study was to develop a problem-solving model for diabetes mellitus in a community, in the  
 hope that it could reduce hemoglobinA1C and increase the quality of life of diabetes mellitus  
 patients. The diabetes mellitus problem-solving activity was operated in six villages of Ubonratana  
 District in Khoan Kaen Province. Fifty-two diabetes mellitus patients participated for six months in  
 the problem-solving activity, which was operated by health volunteers; it involved promoting exercise,  
 controlling diet and optimizing drug compliance. The problem-solving patterns were monthly  
 meetings, home visits and health education. The average hemoglobinA1C of the diabetes mellitus  
 patients was 9.9 percent, but after their participation it dropped to 8.7 percent. The quality-of-life  
 score (WHO QOL short form 26) was 88.7; it increased to 101.1 after the activity. The changes in  
 the average HbA1C and quality-of-life scores are statistically significant. The conclusion of this study  
 was that a diabetes mellitus problem-solving activity in a community may be able to reduce HbA1C  
 and increase the quality-of-life score.
