Abstract: Objective To observe the impact of using the Internet on managing the community health of 2 type diabetes,to explore the new pattern of community diabetes management,and to improve the efficiency of both the management and the treatment. Methods The patients with type 2 diabetes who had been in community management system were selected.A total number of 120 patients were enrolled and randomly assigned into two groups by giving out random numbers.The intervention group(The intervention group adopted new diabetes management based on the technology of Internet,n=60) and the control group(The control group using conventional diabetes management,n=60).Follow-up visits were conducted at the beginning of the study and at the 6th month of the research.During the follow-up visits,the differences of two groups patients were analyzed by comparing blood glucose,blood fat,waist circumference and other indicators.The Diabetes prevention related knowledge,attitude and behavior include: symptoms of diabetes,blood glucose control appropriate value smoking etc,were noted down.There were 11 different indicators. Results There were significant differences in FPG and 2hPG,HbA1C,TC,LDL-C,TG,waistline,and BMI in intervention group and control group(P<0.05).Intervention group patients had more general knowledge about diabetes,including symptoms of diabetes,implications prevention measures of knowledge (98.33%,100.00%,95.00%,98.33%),which were higher than the control group (58.33%,48.33%,25.00%,48.33%),and the difference was statistically significant(P<0.05).The condition of Intervention group patients by adhering the prescribed medication,controlling diet,regular testing blood sugar,the proportion of regular exercise (100.00%,93.33%,95.00%,93.33%),which were higher than the control group(48.33%,50.00%,40.00%,50.00%) improved obviously,and the difference was statistically significant(P<0.05).The proportion of alcohol in the intervention group(10%) than the control group (50%) significantly decreased,the difference was statistically significant(P<0.05). Conclusion Diabetes management mode based on Internet is a more effective method than the previous.It can increase the cognition levels of diabetic patients and self-management ability.It is an effective approach to control of blood sugar,and to get more ideal blood lipid metabolism indexes.
