Associations between 24-hour Movement Behaviors and Health-Related Quality of Life in China, Japan and South Korea Children

Background/Objective: It is important to investigate the combination of movement behaviors—such as physical activity, screen time, and sleep—as children's habitual behaviors over a 24-hour period can affect their health. The aim of this study is to examine whether adherence to the 24-hour movement guidelines is associated with health-related quality of life in children from three East Asian countries. Method: For this cross-study, data were collected from primary school children aged 7–12 years in three countries: Japan (n=786), China (n=1,246), and South Korea (n=1,011). Results: Logistic regression analyses adjusted for covariates confirmed the association of physical well-being, psychological well-being, social support, and peers with health-related quality of life subfactors. Conclusions: Our findings highlight the correlation between 24-hour movement behavior and health-related quality of life in three East Asian children and will contribute to building compelling evidence for an integrated approach to health promotion.
