Summary: In this study, replacing sedentary time with vigorous physical activity (VPA) was beneficially associated with inflammatory biomarkers, while replacing it with moderate physical activity (MPA) bouts was detrimentally associated. Other activity intensities did not show significant associations with inflammatory biomarkers. Further longitudinal research is needed to explore the long-term impacts of reallocating sedentary time with physical activity on markers of systemic inflammation in children.

Summary: This study aimed to assess physical activity patterns among children and adolescents with inflammatory bowel disease (IBD), comparing them with healthy controls. The results showed that pediatric patients with inactive or mildly active IBD have similar physical activity patterns compared with healthy controls, except for male patients who have reduced moderate-to-vigorous physical activity. Most patients with IBD did not meet the recommended levels of moderate-to-vigorous physical activity for health benefits.

Summary: The study found that weight status was associated with meeting physical activity, screen-time, and sleep guidelines among 2nd grade children. A lower proportion of children who were thin, overweight, obese, or morbidly obese concurrently met the guidelines compared to healthy weight children. Future studies should explore causal relationships between these behaviors and weight status.

Summary: The aim of this study was to compare the use of generic and CF-specific cut-points to assess movement behaviors in children and adolescents with CF. Results showed that using generic cut-points may lead to misclassification of activity levels, sleep, and sedentary time in CF patients. In contrast, using CF-specific cut-points can provide more accurate assessment of mild physical activity associated with lung function.

Summary: This study aimed to investigate the intrapersonal, interpersonal, and environmental factors associated with adolescents' participation in leisure-time sports and screen-time. The results showed that internal motivation was positively related to sports participation and inversely related to screen-time. Support from family and coaches, access to neighborhood sports facilities, and fewer barriers were positively associated with sports participation. However, neighborhood social norms were negatively associated with sports participation.

Summary: This study aimed to examine the associations between perceived social support, perceived competence, and physical activity in children with physical and intellectual disabilities during the COVID-19 pandemic. A total of 291 participants aged 6-17 years from 27 special schools in Hong Kong were included. After controlling for demographic variables, perceived competence had a stronger association with physical activity than perceived social support. This study highlights two key facilitators for shaping physical activity involvement among children with disabilities during the COVID-19 pandemic.

Summary: Sleep and daytime movement behaviours are interdependent within a 24-hour day. Sleep parameters like social jetlag and chronotype are linked to health problems and unhealthy behaviours among children and adolescents. This systematic review and meta-analysis examined the relationships between social jetlag, chronotype, physical activity, and sedentary behaviour among children and adolescents aged 3-17 years. The findings suggest a positive association between social jetlag and screen media use, and a higher level of physical activity and lower level of sedentary behaviour among individuals with a morning chronotype compared to an evening chronotype. No relationship was found between social jetlag and physical activity.

Summary: This study examines the temporal trends of physical fitness for Hong Kong children aged 6-12 years from 2003-04 to 2015-16. The results show a small increase in mean height, negligible changes in mean body mass, and a decline in sit-and-reach performance. There is also an improvement in 9-min run/walk performance. However, children with low fitness experience larger declines in certain aspects of physical fitness. The findings suggest the need for targeted health promotion strategies, particularly for children with low fitness.

Summary: The study explores the perceptions of Australian primary school teachers on assessing children's physical literacy (PL) through a mixed-methods design. The results indicate that a majority of teachers support PL assessment and consider movement skills, engagement and enjoyment, relationships, and safety and risk as the most important assessment elements. However, some teachers express skepticism towards PL assessment due to doubts about its relevance and appropriateness, as well as the perceived implicit link between the curriculum and PL framework. The study suggests that professional development, resources, and suitable teacher assessments can enhance teachers' knowledge, confidence, and facilitate the implementation of PL assessments.
