Abstract:The current diabetes classification in China is still based on the etiological classification system of the WHO (1999 edition), which divides diabetes into type 1, type 2, other specific types, and gestational diabetes. However, the clinical characteristics and diagnostic indicators for various types have certain limitations, leading to blurred boundaries between different classifications. As clinical indicators change, patients may transition from one type to another during disease progression. Furthermore, different types of diabetes require different treatment strategies and have distinct prognoses, making accurate classification crucial for diagnosis and the implementation of precision medicine. Recently, there has been growing international attention on the fine classification of diabetes. The "2022 Chinese Expert Consensus on Diabetes Classification and Diagnosis" represents an updated requirement for diabetes classification. Many studies have explored diabetes classification in more detailed and comprehensive ways, with an increasing number of biomarkers involved in the classification. Therefore, this paper aims to review and summarize the emerging classifications both domestically and internationally.
