Most outdoor food advertising (e.g. billboards and bus stops) features foods that are considered unhealthy. The most important technical challenge when designing policies to restrict unhealthy outdoor food advertising is defining 'unhealthy food'. To date, most restriction policies have used nutrient profiling models (i.e. foods are classified according to their nutritional composition) to determine which foods and beverages may be advertised. In Australia, state governments have endorsed a food category-based classification system, with no prescribed nutrient limits, which may create ambiguity when multiple users are identifying food advertisements to be restricted.
Physical activity (PA) surveillance, policy, and research efforts need to be periodically appraised to gain insight into national and global capacities for PA promotion. The aim of this paper was to assess the status and trends in PA surveillance, policy, and research in 164 countries.
This research explored adults' perceptions of how sexualized images typically found on social media might influence adolescent girls' mental health, what support girls might need should they experience mental health difficulties, and how such difficulties could be prevented or reduced.
Knowledge of developmental trends in meeting age-specific 24-hour movement behaviour guidelines is lacking. This study describes developmental trends in device-measured physical activity and sedentary time over a three-year period among Western Australian children aged two to seven years, including differences between boys and girls.
Childcare services such as preschools and long day care centres have been identified as a key setting to promote physical activity in early childhood as they provide access to large numbers of children for prolonged periods. Yet, specific standards for the type and amount of physical activity children accumulate whilst attending childcare are lacking. The purpose of this study was to derive population-referenced percentile values for children's total movement and energetic play whilst attending early childhood education and care services.
The prevalence estimates of physical activity, sedentary behavior, and sleep (collectively known as movement behaviors) in 3- and 4-year-old children worldwide remains uncertain.
24-hour Movement Guidelines for the Early Years promote that achieving all three-movement behaviour (sleep, sedentary behaviour and physical activity) recommendations is important for child health and development. We examined the association between meeting all, none and combinations of the Australian 24-Hour Movement Guidelines for the Early Years and social-emotional development in 1363 preschool (2-5 years) boys (52%) and girls.
Research suggests there is considerable opportunity to improve children's movement behaviors while they are being cared for by their grandparents. An understanding of the extent to which grandparent practices facilitate children's engagement in physical activity is critical to the development of health interventions targeting grandparent caregivers.
To investigate associations between interpregnancy intervals (IPIs) and adverse birth outcomes in twin pregnancies.
Outdoor play in the home yard is an important source of physical activity for many preschoolers. This study investigated if home yard size and vegetation are related to preschooler outdoor play time.
