The aim of this randomized controlled cross-over trial is to explore the efficacy of auricular magnet in treating childhood anorexia. Participants will be allocated to two groups, labeled as Group A and Group B. Prior to the commencement of the trial, parents or guardians of the participants are required to fill out basic information for their children, including age, gender, height, weight, etc., and to complete the Preschooler's Eating Behavior Scale questionnaire. Over the initial 7-day period, participants of Group A receive auricular magnet therapy while participants of Group B undergo placebo magnetic auricular therapy. This is followed by a 14-day washout period to eliminate any lingering effects from the initial treatment. In the second phase, the treatments are swapped between the two groups.

Anorexia in children refers to a disease in which children are not greedy for food for a long time, lose their appetite, and even refuse to eat. From the perspective of Western medicine, anorexia is classified as an eating disorder, and its causes are quite diverse, such as digestive tract diseases, neurological abnormalities, etc. From the perspective of traditional Chinese medicine (TCM), normal spleen and stomach functions are necessary for food digestion. If the spleen and stomach are not in harmony, it will cause symptoms of not breastfeeding and eating. TCM treatment of anorexia in children can be divided into two types: internal treatment and external treatment. The method of internal treatment is to give appropriate prescriptions to patients through syndrome identification and treatment. The methods of external treatment include massage, acupoint sticking, auricular point sticking, scraping therapy, navel pushing therapy, acupuncture and moxibustion, etc. Because children with anorexia do not like to eat, it is not easy to treat anorexia with drugs alone. External therapy can be considered. As traditional medicine is getting more and more attention, many patients seek TCM adjuvant treatment. This study discusses auricular point sticking in external therapy. Auricular point sticking has the advantages of noninvasiveness and convenient operation, and is suitable for children's diseases. However, the current studies on auricular points for children with anorexia are still mostly using the traditional buliuxing seeds, and there is a lack of rigorous clinical research. The aim of this study is to establish a clinical trial of auricular magnets in the treatment of anorexia in children. It is expected that subjects will be recruited from the Department of Traditional Chinese Medicine of the Affiliated Hospital of China Medical University, and the changes in eating behavior before and after treatment will be evaluated by questionnaires to explore the efficacy of auricular magnets.
