Background: While there is growing evidence on 24-hour movement behaviours (physical activity, sedentary behaviour, and sleep) in non-displacement settings, understanding these behaviours among displaced children remains limited. This scoping review explored evidence on 24-hour movement behaviours, including active play and health among forcibly displaced children (birth to 12 years) affected by conflict or natural disasters.

Methods: We followed JBI guidelines and PRISMA extensions for scoping reviews.

Background: Canada, Australia, the World Health Organization and other countries have released 24-hour movement guidelines for the early years which integrate physical activity, sedentary behaviour, and sleep, focusing on supporting children to achieve a healthy 24-hour day. The guideline evidence synthesis, however, highlighted the dearth of high-quality evidence, particularly from large-scale studies. The Sleep and Activity Database for the Early Years (SADEY) project aims to assemble a large, pooled database of 24-hour movement behaviours and health indicators in young children (birth to 5.

Background: Encouraging healthy eating and physical activity in children has long-term benefits for their health and development, however many do not meet the requirements for fruit and vegetable consumption, or physical activity. Experiential learning (EL) has been shown to improve children's healthy eating and physical activity-related knowledge, attitudes, and behaviour. Children's museums provide opportunities for hands-on EL activities that can engage families.

Article Synopsis
  • The 24-hour Movement Questionnaire (QMov24h) was developed to effectively measure sleep, sedentary behaviour, and physical activity, aiming to comply with WHO guidelines.
  • The development process involved input from end-users and experts, as well as comparisons to existing measures for validation, resulting in a significant testing sample of 117 participants.
  • Results indicated that the QMov24h has strong validity for measuring various movement behaviours and shows considerable reliability, making it a suitable tool for evaluating compliance with physical activity guidelines in adults.

Article Synopsis
  • The prevalence of physical activity, sedentary behavior, and sleep among 3- and 4-year-old children globally is unclear, highlighting the need for consistent data.
  • This study analyzed data from 14 cross-sectional studies across 33 countries to determine how many children met WHO guidelines for physical activity, screen time, and sleep over recent years.
  • Only 14.3% of the 7017 children studied met all the guidelines, with no significant differences found between countries with varying income levels regarding adherence to these health recommendations.

Background: Children's physical activity and screen time behaviours impact their physical health and well-being. In Australia, less than half of children meet daily physical activity recommendations and only one-third meet daily screen time recommendations. Nearly half a million Australian school children aged 5-12 attend Outside School Hours Care (OSHC) weekly, activities undertaken at OSHC play a key role in meeting these recommendations.

Background: This study aimed to investigate prosocial behaviour-those behaviours that benefit others or enhance relationships with others-as a mediator of the associations between green space quality and child health-related outcomes (physical activity, mental health, and health-related quality of life (HRQOL)).

Methods: This study involved data from 4983 children with 10-year follow-up (2004-2014) retrieved from the Longitudinal Study of Australian Children. Green space quality (the exposure), prosocial behaviour (the candidate mediator), and child health-related outcomes were assessed biennially based on caregiver reports.

Background: In 2018, the Australian Government updated the Australian Physical Activity and Sedentary Behaviour Guidelines for Children and Young People. A requirement of this update was the incorporation of a 24-hour approach to movement, recognising the importance of adequate sleep. The purpose of this paper was to describe how the updated Australian 24-Hour Movement Guidelines for Children and Young People (5 to 17 years): an integration of physical activity, sedentary behaviour and sleep were developed and the outcomes from this process.

Executive functions and psychosocial health during childhood are positively associated with health and developmental outcomes into adulthood. Electronic media use has been reported to adversely affect health and development in children; however, what remains unclear is whether contemporary media behaviors, such as electronic application (app) use, exerts similar effects on health and development. We investigated the associations of electronic media use (program viewing and app use) with cognitive and psychosocial development in preschoolers.
