1. Children with a family history of diabetes. Human genes are hereditary, and children with a family history of diabetes are more likely to be affected by the causative factors that lead to diabetes and to develop diabetes, so these children should be especially vigilant. 2. Children who are obese or overweight. Children who are obese or overweight account for a large part of the population. Some data show that the incidence of overweight children aged ≤ 18 years old in China is 17.6%. The incidence of obesity 5.6%. The concept of overweight is more than 20% above the ideal weight. Overweight or obesity increases the burden on pancreatic islet cells and reduces the biological activity of insulin receptors. Insulin must bind specifically to insulin receptors in order to exert its normal biological effects. If the secreted insulin does not bind well to the receptor, the body’s glucose metabolism will become abnormal and blood sugar will accumulate excessively in the blood, resulting in hyperglycemia. With the development of medical technology, it is found that many obese children have higher than normal insulin levels in spite of not having high blood sugar during formal islet function tests in hospitals. We also call this hyperinsulinemia. In this group of patients, although insulin production is exceptionally high, the quality is poor and insulin does not bind well to the receptors. Hyperinsulinemia also aggravates the inflammatory response of the systemic vascular endothelium, leading to the occurrence and development of metabolic syndrome. 3, children who eat high calorie, high fat, high protein, high carbohydrate and low dietary fiber for a long time. The “three high” food often lacks dietary fiber. The “three high foods” also lead to long-term high load of pancreatic islet B cells, causing damage or even failure of pancreatic islet cells, and thus the development of diabetes. Some children and adolescents only drink sugary drinks for a long time, not plain water, which is also one of the important causes of diabetes. This is because long-term consumption of large amounts of sugary drinks will also increase the burden on pancreatic islet cells and promote the development of diabetes. 4. Huge fetuses that weigh less than 2.5 kg at birth or more than 4 kg at birth are also prone to diabetes. Because women who have a history of delivering huge fetuses are also prone to diabetes, huge fetuses have a genetic factor for diabetes, so parents should pay special attention. 5, children’s long-term mental stress, sedentary lifestyle. Many children have unhealthy lifestyles such as being fat and not exercising, playing games on the Internet for long periods of time, watching TV, etc., which causes excessive mental tension. Long-term mental stress can lead to a rise in the body’s glucagon group to antagonize the insulin within the body, which can also induce diabetes. Any of the above five should be given high attention, vigilance, and scientific interventions that have the potential to keep many children who are close to diabetes from developing it. In addition, people at risk for diabetes need to have the idea that they need to be both highly concerned and confident. Even children with a family history of diabetes should not be afraid. Not all people at risk will necessarily develop diabetes. With a scientific lifestyle, it is possible not to have diabetes.
