This review discusses the increasing prevalence of EGID among children and adolescents and highlights the complexities involved in its diagnosis and management. This review begins with a thorough examination of the diverse clinical presentations of EGIDs in Korean children, with a special focus on common gastrointestinal symptoms such as abdominal pain, diarrhea, and bloody stool. Additionally, we explored extraintestinal manifestations, including growth failure, malnutrition, and associated allergic comorbidities, highlighting their importance in the clinical landscape of EGIDs. Because of its subtle and overlapping symptoms with those of other gastrointestinal disorders, EGID is frequently underdiagnosed. Addressing this challenge requires maintaining a high index of suspicion and employing a comprehensive diagnostic approach to differentiating EGID from functional gastrointestinal disorders (FGIDs) and other inflammatory or systemic diseases such as inflammatory bowel disease. The optimal management of EGID requires a collaborative multidisciplinary strategy that includes dietary management, regular monitoring, and tailored medical interventions.

We aimed to provide evidence of this potential, this multiphase, multimethod, and integrative review comprehensively investigated the global trends in health promotion initiatives and status of the Korean pediatric population. This integrative review comprised three phases employing various review methods: an environmental scan of existing guidelines for 24-hour movement behaviors worldwide, a rapid review of physical activity-related indicators from Global Matrix data, and a systematic review of 24-hour movement behaviors among children and adolescents in South Korea. The growing recognition of a holistic approach to the 24-hour movement behavior paradigm in pediatric health promotion has led to the establishment and adoption of 24-hour movement guidelines in different countries and by the World Health Organization (WHO). Korean health authorities have also responded to this need by releasing a translated report of the WHO guidelines for physical activity and sedentary behavior as well as the 2024 update of the Physical Activity Guidelines for Koreans. Accordingly, actions must be followed in policy, research, and practice. This is critical considering that Korean children and adolescents exhibit an unfavorable profile of 24-hour movement behaviors compared to the global average. Among those aged 0-6 years, the weighted averages for guideline adherence were 18.2% for physical activity, 38.1% for sedentary behavior, and 76.2% for sleep.
