Overview and Methods for Chinese National Surveillance on Students’ Common Diseases and Risk Factors, 2022

Child and adolescent health plays a critical role in shaping future public health and intergenerational outcomes. In China, rising rates of myopia, obesity, mental health issues, and other common conditions highlight the need for continuous monitoring. Since 2016, the Chinese National Surveillance on Students’ Common Diseases and Risk Factors (CNSSCDRF) has provided comprehensive, nationwide data on student health. By 2022, the system had expanded to nearly all counties, tracking key indicators such as vision problems, overweight/obesity, dental caries, and health-risk behaviors across multiple administrative levels. This review outlines the surveillance methodology, including sampling, data collection, and analysis. Findings have directly informed school health policies and technical guidelines, supporting national goals such as those in the Healthy China 2030 Plan.
