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 3 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. For those aged 12-18 years, the weighted averages for guideline adherence were 20.4% for physical activity, 55.9% for sedentary behavior, and 26.2% for sleep.

Hence, here we identified and reviewed original research papers published in 2017-2023 across 11 database categories in PubMed, Google Scholar, Scopus, and Web of Science to improve our understanding of MPs with a focus on pediatric well-being. These studies found that milk and infant formulas are common sources of MP exposure in infants. Infant formula is the dominant source of MPs in babies, while plastic toys are a common source of MPs in toddlers. Adolescents are frequently exposed to MPs through the consumption of food contaminated with MPs and the use of plastics in food packaging. Water and air are sources of MP exposure in children from infancy through adolescence. This study thoroughly summarized how MP exposure in children of all ages causes cell damage and leads to adverse health effects such as cancer. With appropriate authorization from the relevant authorities, small amounts of human biological samples (10 g of feces) were collected from volunteers to assess the amounts of MPs in children with the aim of promoting pediatric well-being.

The younger the gestational age of preterm infants, the higher the risk of survival despite severe neurodevelopmental impairments. For infants born at 22-23 weeks' gestation, the limit of viability, neurodevelopmental outcomes, and survival rates may be determined by the quality of proactive care. Owing to the high risk of severe neurodevelopmental impairment in 22-23 weeks' gestation, proactive care is sometimes withheld according to ethical or legal considerations, and there are significant differences in the provision of proactive care and survival rates across countries or institutions. Additionally, there are differing or even lacking guidelines regarding the care of these infants across countries and institutions. Japan and Sweden are countries with well-established national guidance and proactive care for infants born at 22-23 weeks' gestation, resulting in higher survival rates among them. In Korea, where there is an extreme shortage of neonatologists, maternal transfer before delivery at 22-23 weeks' gestation to high-activity regions with appropriate neonatal intensive care unit resources, such as adequate personnel and facilities similar to the centralized care model seen in Sweden, is crucial for improving the survival rates of infants born at 22-23 weeks' gestation.
