The Association Between Watching Mukbang Videos and the Appetite of Children With Cancer

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to record the Mukbang watching behavior and appetite of children with cancer during inpatient radiotherapy and chemotherapy through intensive longitudinal study, explore their correlation, and the impact on their nutritional status and quality of life, and formulate for clinical departments relevant interventions and management options provide a theoretical basis.

Detailed Description
-----------------
World Health Organization（WHO） data shows that the prevalence of malnutrition in children with cancer is as high as 75%, which leads to decreased immune function in children with cancer, unsatisfactory treatment effect, increased adverse clinical outcomes, early tumor recurrence, prolonged recovery time, and death. risk factors such as increased rates. The Global Childhood Oncology Initiative proposed by WHO in 2020 pointed out that reducing hunger and malnutrition and improving the outcomes of children with cancer are one of the main tasks of providing best practices in pediatric oncology care. The excessive consumption of the body caused by the cachexia of the tumor itself cannot be changed. Nutritional intake is the only adjustable factor for malnutrition in children with tumors. Loss of appetite is the main reason for insufficient nutritional intake. Numerous clinical studies have explored the nutritional management of children with cancer. However, most nutritional interventions are ineffective due to poor appetite and food intake in children. The investigation in the clinical ward found that in order to cope with the problem of loss of appetite, many children with cancer took the initiative to watch Mukbang during hospitalization to relieve gastrointestinal symptoms and increase appetite. At present, studies have shown that Mukbang may have the potential to improve the appetite of children with tumors. In addition, watching Mukbang is a way that children actively choose to increase their appetite, which has better acceptability. Intensive longitudinal study can explain the dynamic changes of children's behavior and appetite when watching Mukbang videos by sampling in a natural context for a short period of time and multiple times, and based on real-time data, further Explain in detail the persistent effect of watching Mukbang video behaviors on appetite.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Questionnaires assessed children with cancer<br>Children with cancer who received at least one radiotherapy and chemotherapy during hospitalization | Other: Questionnaires set<br>* At baseline, the children's demographics, disease-related data, characteristics of Mukbangwatching behavior, appetite, nutritional status, and quality of life data were collected. From the first day of radiotherapy or chemotherapy, 3 meals a day for 5 consecutive days were followed to track the children's appetite status and the characteristics of Mukbangwatching behavior. Their nutritional status and quality of life were tracked at the end of treatment or when they were discharged from the hospital.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Appetite | The appetite will be assessed by Cancer Appetite and Symptom Questionnaire(CASQ) . The questionnaire consisted of 12 items, each item ranged from 0 to 4 points, and the total score of the questionnaire ranged from 0 to 48 points. The lower the total score, the worse the patient's appetite. | Appetite change over 5 days during chemoradiotherapy from baseline | 
| Mukbang Watching Features | The Mukbang watching features will be assessed by a questionnaire designed by the researcher and recorded by the subjects themselves, including watching time, watching rate, watching preferences and watching experience. | Mukbang Watching Features change over 5 days during chemoradiotherapy from baseline | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Nutritional status | The nutritional status will be assessed by using the Subjective Global Nutritional Assessment（SGNA）. Assessment included the children's recent height, weight, parental height, dietary intake, changes in appetite, frequency and duration of gastrointestinal symptoms, and recent physical activity and changes. This provides a comprehensive assessment of the nutritional status of children, with ratings classified as well-nourished, moderately malnourished or severely malnourished. | Change in nutritional status over 7 days from baseline | 
| Quality of Life in children with cancer | The quality of life in children with cancer will be assessed by using the Pediatric Quality of Life Inventory Measurement Models 3.0（PedsQLTM-3.0-cancer）.The model has a total of 27 items, including 8 subscales, each item used a 5-point Likert scale, (0=never, 1=almost never, 2=sometimes, 3=often, 4 = almost always), higher scores indicate better quality of life. | Change in quality of life over 7 days from baseline |
