Yesterday, the U.S. Preventive Services Task Force (USPSTF) issued a statement of recommendations for screening for type 2 diabetes in asymptomatic overweight and obese people aged 40 to 70 years, every 3 years, to reduce the risk of cardiovascular disease in the population. If there is a family history of diabetes or a clinical history of abnormal glucose metabolism, screening for diabetes at a younger age is recommended. There are three methods of blood glucose screening: glycated hemoglobin (HbA1c), fasting blood glucose, and oral glucose tolerance test (OGTT). Abnormal glucose metabolism includes abnormal fasting glucose, impaired glucose tolerance, and type 2 diabetes, with specific diagnostic criteria listed in the table below. The USPSTF states that once abnormal glucose is detected at screening, intensive lifestyle intervention should be the first step, balancing both diet and physical activity. The USPSTF also recommends the following: 1. Adults who are obese or overweight with other cardiovascular risk factors should receive intensive lifestyle interventions; 2. Men ≥35 years of age and women ≥45 years of age at increased risk for coronary heart disease should be screened for dyslipidemia; 3. Adults ≥18 years of age should be screened for high blood pressure; and 4. Clinicians should ask all patients whether they smoke, and should give advice on cessation of smoking. Intervention recommendations. The 2013 JAMA report shows that there are more than 92 million people with diabetes in China, most of whom do not know they have diabetes. more than 90% of the population has diabetes from acquired causes, with obesity being the most important factor!
