Background: The World Health Organization estimates that child mental disorders will increase by 50% globally by 2020, becoming one of the leading causes of illness, death, and disability. In China at present, the mental health situation of children and adolescents is also very serious. The Institute of Mental Health of Peking University has conducted a survey on the prevalence of childhood behavior problems among elementary school students in certain urban areas of Beijing, which was 8.3% in 1984, 10.9% in 1993, 13.4% in 1998, and 18.2% in 2001. A survey published by the Shanghai Women’s Federation in 2005 showed that the incidence of psychological disorders among primary and secondary school students in Shanghai had reached 21% to 32%. In Beijing Anding Hospital, no one could have imagined that the children’s ward would look like a kindergarten: the walls of the corridor were decorated with children’s drawings, including flower dresses, cat faces, sunflowers and big trees. The classroom was decorated with desks and chairs, bookcases filled with all kinds of toys, blue cat cartoons on the wall, and a small red flower competition list. And the little patients were carefully working on puzzles under the guidance of their teachers. But these lucky children are only a very small part of the many children with mental illness, and there are many children with mental illness who are not properly treated and suffer from the disease. Zheng Yi, deputy director of the Chinese Children’s Mental Health Professional Committee and professor at Anding Hospital, told reporters that at least 30 million children and adolescents under the age of 17 in China are suffering from various emotional disorders and behavioral problems. Among them, the prevalence of mental disorders among primary and secondary school students is 21.6 to 32 percent, highlighted by problems in interpersonal relationships, emotional stability and learning adaptation. Because childhood psychiatric disorders are difficult to detect and diagnose, it is internationally estimated that about 20% of minor illnesses are correctly diagnosed and treated, but more than 90% of “problem children” in China are misdiagnosed and misdiagnosed. One of the reasons why “problem children” are misdiagnosed and misdiagnosed is that many parents are unaware that their children may have psycho-psychiatric problems. Prof. Zheng Yi said that the initial symptoms of mental illness in children include a sudden drop in learning, erratic behavior, depression, talking to oneself or blinking, shrugging, telling lies, and lack of concentration. Since many children’s mental and psychological problems are less obvious, most parents and doctors lack knowledge of psycho-psychiatric disorders and ignore these abnormal behaviors, delaying treatment, while others are tossed between pediatrics and internal medicine for years, without proper treatment. Another reason for the low consultation rate is that parents are afraid to seek treatment. Although many children and adolescents suffer from various mental illnesses and psychological disorders, only 20% of them are treated in professional mental health institutions. It is indeed very difficult for parents to tell that their children are being treated in psychiatric hospitals.
