When compared to the rest of the world, the prevalence of diabetes and cigarette smoking was much higher in China. In Guangdong Province, 34.08% of the population smokes, compared to 34.17% nationally. More than 20.8% of the Chinese population is diabetic as of today. The projected global population growth by 2030 is 42.3 million. The increasing number of people smoking, and the devastating number of people diagnosed with diabetes are two of the biggest issues in China's public health system. There have been few case control studies in China investigating the link between cigarette smoking and diabetes (Ko GT. et al., Hong Kong; Chan AM. et al., Jiangxi). Both studies demonstrated a correlation between smoking and diabetes, and the case control study also discovered a dose-response relationship between daily cigarette use and DM; however, further investigation into the long-term effects of smoking exposure and the relationship between smoking and other risk factors is necessary. This study aims to determine whether cigarette smoking is a risk factor for developing diabetes. Cigarette smoking is associated with an increased risk of getting diabetes, according to many studies.
