| Background:Diabetes (Diabetes mellitus, DM) is a series of clinical syndrome about metabolic disorders, which involve sugars, protein, fat, water, electrolytes and so on. The reason for that is the interaction of genetic and environmental factors, the absolute or relative lack of insulin secretion and decreasing.sensitivity of cells to the insulin. Now the prevalence of diabetes in the world increase sharply, and the number of patients with diabetes is 135 million in 1997, which increases to 177 million in 2001. we predict the number in the worldwide will reach 300 million by 2025With the development of medical science, medical model has been transformed from a single biomedical model to a multi-dimensional biological-psychological-social medical model. People's health needs are also from disease control in the past developed into the longevity, health, proper nutrition and maintaining a good mental state and social functions. Therefore, we should not only consider the basic treatment measures, but also launch health education to improve patients'quality of life for patients with chronic diseases, especially for diabetes. World Health Organization (WHO) classifies health-related quality of life (health-related quality of life, HRQOL), which is the quality of life (QOL), as a new health indicators. It can evaluate the physical, psychological and social functional status of the individuals and groups comprehensively .Objective:To analyze the influencing factors of the quality of life through the survey on community patients with type 2 diabetes mellitus, explore the effects of health education on the quality of life, Social support and Coping style. in patients with type 2 diabetes in the community, and provide a theoretical and practical basis to the treatment of patients with type 2 diabetes.Method:1. Baseline surveys:The project area for research was Xiaodian District, Taiyuan. We selected the patients (243 cases) complying with type 2 diabetes diagnostic criteria (WHO recommended diagnostic criteria) from their communities, and they moved and thinked normally. We ruled out the patients with non-diabetic severe organ lesions. They fillouted questionnaires under a unified organization by investigators, and 224 valid questionnaires were regained. Finally we learn the status quo of the quality of life in patients with type 2 diabetes in the community by a statistical analysis.2. Interventions:We randomly selected 96 patients from 224 patients of the baseline survey, and they were also randomly divided into intervention group (48 cases) and control group (48 cases). The intervention group was done with "peace of mind hypoglycemic and enjoy the health" as the theme, health education as the dominant form to explore the effects of health education on the quality of life in patients with type 2 diabetes in the community, and the control group didn't take any measures.3. The latter part of the investigation:The intervention group and control group members secondly filled out the same questionnaire and did the same biochemical indicators of blood glucose testing within 1 week after the intervention, to evaluate the effects of health education on the quality of life in patients with type 2 diabetes in the community.Results:1. Baseline survey resultsTotal score on quality of life, coping style score and social support total score in patients with diabetes had no significant difference with the sex, occupation, age and family history (P＞0.05). But all the 3 scores in patients with diabetes had significant difference with whether there are complications or not (P＜0.05). The score of the patient's negative response to whether there are complications was no significant difference (P＞0.05).2. Evaluation of intervention effect2.1 The scores on the psychological and social dimension of the intervention group after intervention were significantly lower than the control group, and the difference was statistically significant.2.2 The scores on the negative and positive response of the intervention group after intervention had significant difference with those of the control group (P＜0.05).2.3 The scores on the subjective support and supporting utilization and the total supporting score of the intervention group after intervention had significant difference with those of the control group (P＜0.05)Conclusion:Health education can improve the quality of life of patients with type 2 diabetes mellitus from psychological and social aspects, reduce the two-hour postprandial blood glucose values of patients, ameliorate the patient's coping style, and enhance the patient's social support.
