Brief summary: This study plans to understand the prevalence and clinical characteristics of pediatric functional gastrointestinal disorders in mainland China through multi-center investigation and clinical epidemiological analysis, to reveal the prevalence characteristics and related factors of functional gastrointestinal disorders in children of all ages in mainland China, to establish a diagnostic standard system for pediatric functional gastrointestinal disorders in mainland China, to provide evidence-based basis for the formulation of new Roman standard for functional gastrointestinal disorders, and to provide new ideas and treatment basis for the diagnosis and treatment of functional gastrointestinal disorders in children.

Detailed description: Functional gastrointestinal disorders (FGIDs), also known as brain-intestinal interaction abnormalities, are associated with dynamic disorders, high visceral sensitivity, changes in mucosal and immune functions, changes in intestinal flora, and abnormal central nervous system regulatory functions. FGIDs are the most common causes of diagnosis and treatment of gastrointestinal diseases in children. During the past 10 years, new progress has been made in the study of various FGIDs in children of different ages. FGIDs Rome Commission of Experts revised the relevant diagnostic criteria and officially published the Rome IV criteria for pediatric FGIDs in Gastroenterology in 2016. Due to many factors, the epidemiological survey data of pediatric FGID are still lacking in China. Whether Rome II, Rome III or Rome IV, their diagnostic criteria and epidemiological data were from other countries and regions, so their suitability for China's children remains to be verified. This study plans to understand the prevalence and clinical characteristics of pediatric functional gastrointestinal disorders in mainland China through multi-center investigation and clinical epidemiological analysis, to reveal the prevalence characteristics and related factors of functional gastrointestinal disorders in children of all ages in mainland China, to establish a diagnostic standard system for pediatric functional gastrointestinal disorders in mainland China, to provide evidence-based basis for the formulation of new Roman standard for functional gastrointestinal disorders, and to provide new ideas and treatment basis for the diagnosis and treatment of pediatric functional gastrointestinal disorders.
