Many people believe that obesity will lead to diabetes, and lack of exercise will lead to diabetes, but few people know that tobacco use and second-hand smoke inhalation can also lead to diabetes. Evidence shows that the larger the amount of smoking, the younger the age of starting smoking, and the longer the number of years of smoking, the higher the risk of diabetes. Understanding the scientific fact that tobacco use and second-hand smoke are very serious risk factors for diabetes can keep the public away from diabetes and its complications. "The situation of prevention and control of diabetes in China is not optimistic." Li Jianhong, a researcher from the Metabolic Disease Prevention and Control Office of the Chronic Disease Center of the Chinese Center for Disease Control and Prevention, recently introduced at the information exchange meeting on tobacco use and diabetes held by Xintan Health Development Research Center. According to the 2021 Global diabetes Map released by the International diabetes Federation (IDF), the number of adult diabetes patients in the world will reach 537 million in 2021, including about 140 million Chinese patients. "In 2022, the China diabetes Map jointly released by the Chronic Non communicable Diseases Prevention and Control Center of the China Center for Disease Control and Prevention and Beijing Hospital shows that the prevalence of type 2 diabetes in China has been on the rise since 1979, and it is still in a rapid growth stage, and there will be no plateau or decline in the short term." Li Jianhong pointed out that the rapid rise in the prevalence of diabetes has also caused a huge economic burden. "Corresponding to the serious disease burden and economic burden of diabetes, the awareness rate, treatment rate and control rate of diabetes in China are still at a low level. The 2018 monitoring results of chronic diseases and risk factors in China show that the awareness rate of diabetes among adults aged 18 years and above in China is only 38.0%, the treatment rate is 34.1%, and the control rate is only 33.1%, which still has a large gap with developed countries." Xiao Lin, director of the Tobacco Control Office of the Chinese Center for Disease Control, introduced the results of an adult tobacco survey conducted from July 2022 to May 2023. The research subjects of this tobacco survey are Chinese residents aged 15 and above who do not live collectively. 200000 people from 630 monitoring points in 31 provinces participated in the survey, including information on tobacco use, e-cigarette use, smoking cessation, exposure to second-hand smoke, prices, and so on. The survey found that in 2018, the smoking rate among people aged 15 and above was 26.6%, while for men it was 50.5%; The smoking rate among the population aged 15 and above in 2022 is 24.1%, with 45.3% for males and 2.3% for females. The smoking rate among people aged 15 and above has shown a downward trend, with a relatively large decrease in the smoking rate among men. In addition, the second-hand smoke exposure rate of non-smokers aged 15 and above in China was 52.4% in 2022, a decrease of 15 points compared to 2018. The situation of second-hand smoke exposure continues to improve, and some progress has been made in creating a smoke-free environment. Professor Li Guangwei, chief endocrinologist of China-Japan Friendship Hospital and leader of endocrinology discipline of Fuwai Hospital, Chinese Academy of Medical Sciences, scientifically and systematically expounded the relationship between smoking and diabetes, cardiovascular disease and death. He stressed that diabetes has greatly harmed human health, reduced people's quality of life and shortened life span. People with diabetes are confronted with cardiovascular and cerebrovascular diseases and
