Diabetes mellitus is a chronic metabolic disease associated with a high rate of disability and mortality. Prediabetes is the intermediate stage from normal blood glucose to diabetes. Reversal of prediabetes can help reduce the incidence of related complications and reduce premature mortality. Therefore, the early treatment of prediabetes is crucial, detection and effective management of this large population in time is the key to prevent diabetes. Overweight/obesity is one of the key risk factors leading to prediabetes and diabetes. In order to delay the progression of prediabetes and prevent related complications, weight loss is a key strategy to reverse prediabetes in overweight/obese patients. Lifestyle intervention is the first-line treatment for weight loss and is the most suitable intervention method. Although weight loss has been shown to have many metabolic benefits, it is a great challenge in the real world due to the long-term and complex of weight management. In order to further optimize the weight loss treatment of prediabetic patients, the study apply the mobile internet intelligent healthcare big data technology, 100 overweight/obese prediabetic patients who met the enrollment conditions were randomly divided into control group and intervention group by 1:1, with 50 patients in each group. The control group was treated according to the traditional diagnosis and treatment mode, and the diagnosis and treatment plan was formulated by the endocrinologist, and the diet education was conducted by the dietitian, and the individualized diet plan was formulated. Given a calorie-restricted diet, it is recommended to reduce daily energy intake by 500kcal on the basis of requirement. At least 150 minutes of moderate-intensity exercise per week is recommended. After the visit, the patient underwent follow-up self-weight monitoring and diet management outside the hospital. The intervention group was managed by co-management of three disciplines (endocrinologists, dietitians and weight managers). The three disciplines team tracked and assessed the patients' daily diet and weight changes, and gave guidance. The duration of intervention was 6 months. To explore the impact of the new model of mobile internet healthcare and three disciplines co-management on overweight/obese prediabetic patients, and whether it can improve the weight, glycemic and lipid metabolism and insulin resistance, and compare the reversal rate of prediabetes in the two groups.
