Youth mental health has emerged as an increasingly pressing concern in China, with disorders such as anxiety and depression showing earlier onset, higher prevalence, and greater severity. According to the 2024 Report on Youth Mental Health in China, approximately 14.8% of adolescents face varying levels of depressive risk, including 4.0% at severe risk and 10.8% at mild risk. Adolescents experiencing parental absence, inadequate parental care, poor parent-child communication, distant teacher-student relationships, or negative peer interactions are particularly vulnerable. Key risk factors include intense academic pressure, strained family relationships, excessive internet use, and adverse social environments, whereas supportive family education, strong school engagement, and positive psychological resources serve as critical protective factors. To address these challenges, China is developing a multi-tiered mental health support system. The government has strengthened collaboration among families, schools, and communities to promote an integrated educational mechanism targeting core determinants of youth mental health. The Ministry of Education has incorporated mental health education into primary and secondary curricula, established on-campus counselling centres and crisis response systems, and implemented standardized screening with individual psychological health records from enrolment. Universities have introduced entry-level assessments and longitudinal monitoring, supported by well-resourced counselling centres. Concurrently, the public health sector has expanded community-based psychological service platforms, enabling social workers and volunteers to provide accessible mental health support. Digital initiatives such as the Youth Psychological Service Cloud leverage artificial intelligence to deliver online screening tools and self-help resources, extending coverage to underdeveloped regions and accelerating the digitalization of national youth mental health records. For example, the Mental Health Education and Counselling Centre at Sun Yat-sen University launched the "Yixin" large-scale AI model, integrating AI with professional psychological expertise to enhance teaching and counselling functions. Looking ahead, China's youth mental health efforts should emphasize cross-sector collaboration, localized research, and professional talent development.
