Global trends in importance of 24-hour movement behaviors to pediatric health: Implications for South Korea.

Abstract

Cultivating a 24-hour movement behavioral profile conducive to health and well-being, marked by adequate levels of physical activity, limited screen time, and sufficient sleep, has emerged as an important avenue for promoting pediatric health. 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. 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. Building on these current findings, this integrative review provides three priorities for pediatric health promotion policy and practice and three recommendations for future research.
