Several randomized controlled studies have shown that appropriate lifestyle interventions in the IGT population can delay or prevent the onset of type 2 diabetes. The lifestyle intervention group of the Daqing Study in China recommended that patients increase their vegetable intake, reduce alcohol and simple sugar intake, encourage weight loss in overweight or obese patients (BMI > 25 kg/m2), and increase daily activity with at least 20 minutes of moderate intensity activity per day; lifestyle intervention for 6 years resulted in a 43% reduction in the cumulative risk of developing type 2 diabetes over the next 14 years. The Lifestyle Intervention Group of the Finnish Diabetes Prevention Study (DPS) recommended individualized diet and exercise instruction with at least 30 minutes of aerobic and resistance exercise per day, with a goal of 5% weight loss and a fat intake of <30% of total calories; the study resulted in a 43% reduction in the risk of type 2 diabetes at an average follow-up of 7 years. The lifestyle intervention group of the U.S. Diabetes Prevention Program (DPP) study recommended that patients consume a low-fat diet with less than 25% of calories from fat, or calorie restriction if weight loss was not achieved; 50% of patients in the lifestyle intervention group lost 7% of their body weight and 74% were able to maintain at least 150 minutes of moderate-intensity exercise per week; lifestyle intervention for 3 years reduced the risk of progression to type 2 diabetes with IGT by 58%. The risk of progression from IGT to type 2 diabetes was reduced by 58% over 3 years of lifestyle intervention. After a cumulative follow-up of 10 years, the benefits of type 2 diabetes prevention persisted despite weight regain in the lifestyle intervention group. In addition, studies in patients with IGT in other countries have also confirmed the effectiveness of lifestyle interventions in preventing the development of type 2 diabetes. Chinese guidelines for the prevention and treatment of type 2 diabetes recommend that patients with prediabetes should reduce the risk of developing diabetes through dietary control and exercise, with regular follow-up and psychosocial support to ensure long-term adherence to a good lifestyle; regular blood glucose checks; and close attention to other cardiovascular disease risk factors (e.g., smoking, hypertension, dyslipidemia, etc.) with appropriate interventions. The specific goals are: 1) to achieve a BMI at or near 24 kg/m2 for overweight or obese patients, or to reduce body weight by at least 5% to 10%; 2) to reduce total daily dietary calories by at least 400 to 500 kcal (1 kcal = 4.184 kJ); 3) to reduce saturated fatty acid intake to less than 30% of total fatty acid intake; 4) to maintain moderate intensity physical activity for at least 150 minutes/week. 4. moderate intensity physical activity of at least 150 minutes/week. There is insufficient evidence for the long-term efficacy and health economic benefits of pharmacologic interventions, and therefore pharmacologic interventions have not been widely recommended as the primary means of diabetes prevention in national clinical guidelines. Given the early stage of economic development and the significant regional imbalances in China, and the inadequacy of the health care system related to diabetes prevention, this guideline does not recommend the use of pharmacologic interventions at this time. Therefore, this guideline does not recommend the use of pharmacological interventions for the prevention of diabetes for the time being.
