With a high incidence of the condition worldwide, type 2 diabetes has emerged as one of the most worrisome chronic diseases. Type 2 diabetes has been identified in certain public health research to have an early beginning tendency, and the rapid rise in teen and child prevalence may be an epidemiological warning sign. This study uses systematic retrieval and induction techniques to examine the prevalence and trajectory of type 2 diabetes in children and adoles-cents. In this paper, the useful data and literature collected are discussed and sorted out in an attempt to establish a complete field of analysis of current type 2 diabetes, which is to criti-cally discuss the practice of current epidemiological surveillance and screening systems for adolescents and children, and to propose possible constructive suggestions. This study finds that the development trend in adolescents and children may not be optimistic, and there are differences in risk based on geographic demography, gender, race, etc. Epidemiological screening and surveillance of type 2 diabetes in adolescents and children, as well as targeted public and individual prevention and intervention, could have significant implications.
