2010~2020中国内地初中生心理健康问题检出率的元分析

he prevalence of mental health problems of junior high school students is very different in many studies, which fails to provide sufficient basis for the formulation of mental health policy and the construction of mental health service system. In order to identify the overall prevalence of mental health problems and clarify its influencing factors, a meta-analysis of literature retrieved from 2010 to 2020 was performed. The results showed that: (1) Junior high school students faced different degrees of mental health problems, among which the prevalence of anxiety, depression and self-harm ranked in the top three. (2) Some aspects of mental health problems of junior high school students showed a worsening trend with the development of the years, especially anxiety and suicide attempt. (3) The prevalence of mental health problems of junior high school students is seriously affected by the inconsistency of measurement tools, detection criteria and detection time. (4) Generally, the prevalence of mental health problems in junior high school students increases with the grade, especially anxiety. (5) The prevalence of mental health problems among girls is higher than that of boys, especially suicide. (6) Junior high school students in the central and western regions are more likely to have mental health problems, especially anxiety and self-harm, than those in the northeast and eastern regions. In the future, scientific measurement tools and standards should be developed based on the Chinese background, and a mental health dynamic monitoring system and school mental health service system should be established.
