Research on the Influence of Mukbang on Brain Activation in Children With Cancer Based on fMRI

Overview

This study aims to use the intervention study method to extract and verify the effective ingredients in Mukbang that promote appetite and eating in children with tumor during radiotherapy and chemotherapy, and to analyze and explore their potential mechanisms of action based on functional magnetic resonance imaging.

Cancer has a high incidence among children and adolescents worldwide. In October 2020, the World Health Organization (WHO) released an overview of the Global Action on Childhood Cancer which showed that more than 400,000 children under the age of 19 were diagnosed with cancer worldwide every year. With the development and progress of diagnosis and treatment technology, the health outcome of children with cancer has been greatly improved. However, the side effects and complications associated with cancer and its treatment can seriously affect the appetite and food intake of children with cancer, resulting in malnutrition and a low quality of life. Therefore, it is very important to effectively improve the appetite of children with cancer during treatment. Clinical methods to improve the appetite of cancer patients mainly include drugs, diet or nutrition intervention, traditional Chinese medicine and acupuncture, but each intervention has its own advantages and disadvantages which makes the clinical application effect difficult to evaluate, in urgent need of more effective solutions to solve this problem. Mukbang has shown great potential in helping children with cancer to improve their appetite and food consumption, finally promote nutritional health. Mukbang is a method independently chosen by hospitalized cancer children with radiotherapy and chemotherapy to help promote appetite, which has a natural high acceptance. What's more, the features of Mukbang, such as high-quality and clear pictures, relaxed atmosphere created by the video makers, sounds while eating, and attractive images of food, may promote viewers' appetite and increase their intake imperceptibly. In addition to that, watching Mukbang while eating can also provide a pleasant eating experience for children with cancer, and the interaction with the Mukbang anchor can also alleviate the loneliness of children who live in hospital for such a long time, so as to enhance the children's taste experience, relieve the negative emotions of loneliness and depression and promote their appetite and interest in food under the condition of ensuring a healthy diet. Research has found that Mukbang can help people with low appetites increase their food intake and provide vicarious satisfaction to those who overeat. Several studies have shown that videos containing food cues can increase viewers' appetite and decrease feelings of satiety to a certain extent. At the same time, Mukbang can also increase viewers' taste experience on the basis of physics and improve children's interest in food. Therefore, on the basis of existing studies, this study will use functional magnetic resonance imaging and cross-case analysis to extract and verify the effective ingredients in Mukbang that promote appetite and eating in children with tumor during radiotherapy and chemotherapy, and analyze and discuss their potential mechanism of action, aiming to provide a new direction for clinical departments to develop nutritional intervention measures and management programs for children with cancer.
