With the rapid development of national economy, the living standard of human beings has been greatly improved, and the disease spectrum and health concept have changed accordingly. Chronic diseases (NCDs) have gradually become one of the public health problems that seriously threaten human health [1]. With the change of life style, diabetes has developed into one of the chronic diseases that seriously harm the health of residents. Diabetes mellitus (DM) is a common chronic non infectious disease, which can make the body continuously hyperglycemia and long-term metabolic disorder, and lead to the damage, dysfunction and failure of the whole body tissues and organs, especially the eyes, kidneys, cardiovascular system and nervous system. Severe cases may cause acute complications such as dehydration, electrolyte disorder, acid-base imbalance, ketoacidosis, hypertonic coma and other serious complications [2]. In order to explore the trend of diabetes epidemic characteristics in Beilun District of Ningbo, China and to provide scientific reference for future prevention and intervention program modification, the monitoring data of diabetes in Beilun District of Ningbo, China from 2012 to 2018 were analyzed.

In recent years, with the improvement of living standards and the change of eating habits, bad eating and living habits are eroding the health of residents. The incidence rate of incidence of chronic diseases caused by aging population is increasing. As a coastal city with a good economic development and good living standard, the incidence rate of diabetes in Beilun District of Ningbo, China has always been higher than the average level of the whole city.

The incidence rate of diabetes in Beilun District of Ningbo, China was reduced from 738.35/100 thousand in 2012-2015 years to 538.27/100 thousand in 2016-2018 years, which was well controlled. This is closely related to the prevention and treatment of diabetes through multi sector collaboration in Beilun district. The incidence rate of diabetes reported in the age group 40 and above is the best. The trend of diabetes onset is controlled to a certain extent. The incidence rate of diabetes in the 10 - 19 year old group has been increased for three consecutive years after being controlled. This may be related to the improvement of teenagers’ living conditions, the long-term high sugar and fat intake brought about by their enthusiasm for taking out food service, and the unhealthy living habits such as irregular work and rest and lack of exercise for a long time. Studies have shown that long-term high-energy diet is a major cause of the rapid rise in diabetes incidence rate. [5], the same long-term consumption of red meat and processed meat products can lead to decreased insulin sensitivity and increase the risk of diabetes [6]. It is an effective way to improve the condition of diabetes by changing the diet structure. Many studies have shown that the Mediterranean diet, which is mainly composed of grains, vegetables, fish, milk, fruits and olive oil, has great potential in blocking the occurrence and development of diabetes [7], which may be related to vitamin D, calcium and magnesium ions in milk and a large number of unsaturated fatty acids in olive oil and fish. At the same time, mate analysis showed that vegetarianism was negatively correlated with the risk of diabetes [8]. Even after the correction of body mass index (BMI), the incidence rate of diabetes in meat eating people is 2 times that of vegetarians. The prevalence of type 2 diabetes in vegetarians and vegetarians was 77% and 54% lower than that in non vegetarians [9]. After the full liberalization of the two child policy, the proportion of gestational diabetes between 2016-2018 and 2012-2015 has not been effectively controlled. Among them, there are factors such as the increase in the number of pregnant women. I think the main reason for the increase is the change of diet and living habits and the increase of life pressure. Some studies have shown that the abnormal increase of blood glucose during pregnancy will easily affect the brain development, learning and memory of the fetus, and also increase the risk of cardiovascular disease in the adult fetus. In the prevention and health care work for pregnant women, we should monitor the blood glucose concentration of pregnant women who have gestational diabetes risk, and increase the health diet of pregnant women, effectively improve diet structure and develop good habits, so as to reduce the incidence rate of gestational diabetes mellitus. The occurrence of gestational diabetes mellitus in pregnant women and the change of the environment in early neonatal development may be an inducement factor for the increase of the incidence rate of type 0 - 9 diabetes in children. Body mass index (BMI) is not only an independent, dose-dependent risk factor for diabetes [10], but also a related risk factor for a variety of chronic diseases. The proportion of people with Abnormal BMI in the population with diabetes in Beilun District has increased year by year. Compared with 2012-2015, the proportion of obese people has increased significantly in 2016-2018. It has been found that the proportion of diabetes patients with high salt diet and high fat diet in China of Ningbo is relatively high, while the number of people taking part in physical training is relatively small. Nearly two-thirds of people travel by means of transportation, and the amount of exercise is relatively insufficient [11]. Because the drug intervention needs a lot of capital and human investment, the current lifestyle intervention is the main way of community intervention [12]. At the same time, studies have shown that after three months of intensive intervention including reasonable diet and appropriate exercise, the physiological indexes of blood glucose, blood pressure, blood lipid and other factors that lead to the increased risk of type II diabetes have improved significantly, which is significantly lower than that of the control group and has statistical significance [13]. Only through regular follow-up, the contracted service form of family doctors is adopted, i.e. outpatient doctors provide 1. At the end of each month, the assistant doctors combined with the outpatient doctors’ diagnosis and treatment services to carry out follow-up life style intervention for 8 months, the effect is not good. Because the intervention time is short, it is difficult to completely change the unhealthy life habits and bad behavior habits of patients developed for a long time, and only to a certain extent at the beginning of the intervention, then only to maintain the patients. There was no further improvement in the health level of [14]. It can be seen that the treatment of long-term lifestyle intervention is effective for the treatment and prevention of diabetes.

In order to reduce the incidence rate of diabetes effectively, we need to carry out diabetes related business guidance for primary health care units, promote diabetes prevention and control technologies, popularize diabetes related knowledge, and improve the level of diagnosis and treatment of diabetes management doctors. On the other hand, we should strengthen the prevention and treatment of high-risk individuals, and strengthen the publicity and popularization of diabetes related knowledge in communities and schools, actively guide healthy lifestyle development, raise awareness of the risk factors of diabetes, and enhance the awareness of physical examination among the masses, so as to control the incidence rate.
