Building the Capacity of Adolescents as Researchers
BACKGROUND: Adolescent engagement is critical to ensuring research meets adolescent health and well-being needs; however, it is not common practice. To maintain research quality, meaningful adolescent engagement requires tailored support and training, yet limited resources exist globally. This study aimed to describe the co-creation process and outputs of developing a freely accessible online course to build adolescent research capacity in public…
How do Play Streets impact the psychosocial health of participants, organisers, and communities? A mixed-methods evaluation of Play Streets held in South Australia
Australian adults are experiencing a reduction in community connectedness, and loneliness across all age groups is increasing. A Play Street is a simple concept whereby quiet residential streets are temporarily opened primarily to promote play among children, but they also provide an opportunity for parents and adult community members to connect and socialise. This study aimed to explore the use of Play Streets in generating social connectedness …
Promoting vigorous intermittent lifestyle physical activity (vilpa) in middle-aged adults
The MovSnax app, tested in the present study, is the world's first digital tool aimed specifically at increasing VILPA. The findings of the present study underscore the need for further app refinement, focusing on clarifying its purpose and instructions, boosting user engagement through personalization and added motivational elements, enhancing accuracy in detecting VILPA bouts, implementing clearer feedback mechanisms, expanding customization ch…
Exploring reasons for high levels of food insecurity and low fruit and vegetable consumption among university students post-Covid-19
High rates of food insecurity and low consumption of fruit and vegetables among university students have been observed prior to the COVID-19 pandemic and intensified during the pandemic. This study aimed to investigate food insecurity among university students and its associations with sociodemographic factors, fruit and vegetable consumption behaviours, and preferred campus programs to address these issues. A convenience sample of 237 Australian…
Navigating Neighbourhood Opposition and Climate Change
This pilot demonstrated that Play Streets are a feasible and acceptable way to use streets as outdoor recreation spaces in Sydney's Inner West. The evaluation highlights two elements for future sustainability: managing neighbourhood opposition and adapting to climate change
Identifying effective interventions to promote consumption of protein-rich foods from lower ecological footprint sources
Addressing overconsumption of protein-rich foods from high ecological footprint sources can have positive impacts on health such as reduction of non-communicable disease risk and protecting the natural environment. With the increased attention towards development of ecologically sustainable diets, this systematic review aimed to critically review literature on effectiveness of those interventions aiming to promote protein-rich foods from lower ec…
Higher Prevalence of Food Insecurity and Psychological Distress among International University Students during the Covid-19 Pandemic
The COVID-19 pandemic and related disruptions have not only affected university students' learning and academic outcomes, but also other issues, such as food security status, mental health and employment. In Australia, international students faced additional pressures due to sudden border closures and lack of eligibility for government-provided financial support. This study explored the experiences of domestic and international university student…
Food Co-Operatives
Only 5% of Australian children and adults eat enough fruit and vegetables. Two common barriers are high cost and limited access. Food co-operatives ('co-ops') may have the potential to reduce these barriers. We conducted a scoping analysis of food co-ops in the Sydney region to describe their characteristics and objectives. We also conducted a survey of members and non-members of co-ops to assess their fruit and vegetable intake using validated q…
Association between TV viewing and heart disease mortality
AIMS: Sedentary behaviour (particularly television (TV) viewing) is thought to be a risk factor for cardiovascular disease. We employed a negative control outcome to explore whether the association between TV viewing and heart disease mortality is explained by confounding. METHODS: The sample was drawn from the UK Biobank study and comprised 479 658 participants (aged 56.5±8.0 years; 45.7% men) followed up over a mean of 10.4 years. TV viewing wa…
In Initiative Overload”
Introduction : With two thirds of adults in paid employment and one third physically inactive, workplaces are an important setting for promoting more physical activity. We explored the attitudes and practices of employees and managers from different industries towards sitting and moving at work, to inform the development of acceptable solutions for encouraging businesses to adopt activity-promoting workplaces. Method : We conducted focus groups w…
The evolution of time use approaches for understanding activities of daily living in a public health context
This Supplement aims to raise awareness and knowledge of how time use surveys may be applied to studying health behaviours such as physical activity, sedentary behaviour, and eating. This commentary provides an overview and discussion of the papers in this Supplement about time use and health research, and considers possible future directions for the field
Prevalence and correlates of domain-specific sedentary time of adults in the Netherlands
This study reports high levels of total non-occupational sitting time of Dutch adults. The large proportion of sedentary leisure activities might indicate the potential of strategies aiming to reduce leisure sedentary time. The difference in correlates across sedentary behaviour domains demonstrates the importance of targeting these domains differently in interventions and policies
Too much sitting and all-cause mortality
There is reasonable evidence for a likely causal relationship between sedentary behaviour and all-cause mortality based on the epidemiological criteria of strength of association, consistency of effect, and temporality
Don't worry, be happy
Increasing physical activity volume was associated with higher levels of happiness. Although the influence of physical activity intensity appeared minimal, the association with happiness was domain specific and was strongest for "a lot" of domestic and/or "some" vocational physical activity. Future studies to establish causation are indicated and may prompt changes in how physical activity for improving mental health is promoted
Desk-based workers’ perspectives on using sit-stand workstations
The use of a sit-stand workstation in this group of desk-based office workers was generally perceived as acceptable and feasible. Future studies are needed to explore this in different desk-based work populations and settings
Thinking on your feet”
Sit-stand desks had high usability and acceptability and reduced sitting time at work. Use could be promoted by emphasizing the health benefits, providing guidance on appropriate set-up and normalizing standing for work-related tasks
