The prevalence of eating disorders in children and adolescents is increasing worldwide, even among those of different cultural backgrounds. The age of onset is becoming younger. In addition, the COVID-19 pandemic has affected young people both mentally and physically, and the number of teenage patients has increased markedly. The majority of eating disorders in children and adolescents are AN-R (anorexia nervosa, restricting type), but there are also a small number of ARFID (avoidant/restrictive food intake disorder) patients with no apparent desire to lose weight. The management of AN and ARFID typically involves outpatient treatment, but physical symptoms and accompanying psychiatric symptoms may require inpatient treatment. The number of children and adolescents with eating disorders is increasing, but pediatric institutions are not yet equipped to treat them. We report on our center's trial of a community-based medical consultation. The prognosis for eating disorders in children and adolescents is better than that in adults. However, even if weight is maintained, it is important to support the child's eating behavior as well as that of the child's family. The goal is to maintain daily life. For elementary, middle, and high school students, in particular, collaboration with the school is essential for maintaining physical and mental health. Therefore, we discuss the role of schools in the outpatient treatment of eating disorders in children and adolescents.
