Health literacy profiles of final year pre-service teachers in two initial education programs compared with the general population: A cross-sectional study using the Health Literacy Questionnaire.

ISSUE ADDRESSED: Health literacy (HL) can be developed throughout the lifespan starting from the early years highlighting that educational institutions, curriculum and teachers are powerful settings, places and people that can foster HL in youth. Current research shows that Australian teachers need more support to teach health education that promotes students' HL, with limited research focusing on pre-service teachers (PST). This study aims to identify the HL strengths and challenges of PST at one Australian university across two initial teacher education programs (HPE and primary) and compare their health literacy profiles with that of the Australian general population. METHODS: The Health Literacy Questionnaire (HLQ) was administered in March and April, 2022 to measure HL in Australian PST. The research setting was a university in Sydney, Australia, with two of the University's undergraduate initial teacher education (ITE) programs (Health and Physical Education [HPE] and Primary). Of the 24 PST in the HPE cohort, 23 consented. Of the 70 PST in the Primary cohort, 34 consented. The results were compared with Australian Bureau of Statistics data. RESULTS: The participants' median age was 22.3(4.3) years (SD), age ranged from 20 to 54 years, with 36% of participants under the age of 22 years. When comparing the PST data with the general population there were two significant differences: (1) PST scored significantly higher than the general population for Domain 4 (Social support for health, 3.41 vs. 3.19; p < 0.001; d = 0.57); and (2) the PST scored significantly lower for Domain 9 (Understand health information enough to know what to do, 4.02 vs. 4.27; p < 0.01; d = -0.43). In addition, we found that primary PST had significantly lower scores for domains 5-9 (demonstrative of interactive and critical HL), compared with the general Australian population. CONCLUSIONS: Findings show that PST strengths are that they perceive that there they are able to access social support for health, however the PST find it more difficult to analyse and apply health information, compared with the general Australian population. SO WHAT?: Further understanding of health literacy profiles of Australian PST should influence the design of ITE programs and its health education curricular to ensure that PST are able to further develop their HL understandings and capabilities.

CUREs for high-level Galectin-3 expression.

Galectins are a large and diverse protein family defined by the presence of a carbohydrate recognition domain (CRD) that binds ß-galactosides. They play important roles in early development, tissue regeneration, immune homeostasis, pathogen recognition, and cancer. In many cases, studies that examine galectin biology and the effect of manipulating galectins are aided by, or require the ability to express and purify, specific members of the galectin family. In many cases, E. coli is employed as a heterologous expression system, and galectin expression is induced with isopropyl ß-galactoside (IPTG). Here, we show that galectin-3 recognizes IPTG with micromolar affinity and that as IPTG induces expression, newly synthesized galectin can bind and sequester cytosolic IPTG, potentially repressing further expression. To circumvent this putative inhibitory feedback loop, we utilized an autoinduction protocol that lacks IPTG, leading to significantly increased yields of galectin-3. Much of this work was done within the context of a course-based undergraduate research experience, indicating the ease and reproducibility of the resulting expression and purification protocols.

A cross-sectional study of Australian teachers' health: are work-related factors associated with lifestyle behaviours?

Teacher's lifestyle behaviours are important because they lead to positive health outcomes for teachers themselves and because teachers model behaviour to their students. This cross-sectional study examined the lifestyle behaviours of a large sample of teachers in New South Wales (NSW), Australia and assessed the association between work-related factors and lifestyle behaviours. From February to October 2021, data were collected on the lifestyle behaviours, work-related factors and socio-demographics of primary and secondary school teachers in NSW, via an online survey. Associations between individual work-related factors and lifestyle behaviours were modelled using logistic regression and adjusted for sex, age, number of children and geographic location. Most of our survey sample (n = 1136) were women (75%) and 53% were reported as having overweight or obesity. Only 23% of teachers met the recommended physical activity guidelines, 39% met fruit intake guidelines, 9% met vegetable intake guidelines and 58% met healthy sleep guidelines. Most teachers (78%) met the recommendation of sugar-sweetened beverage consumption, 89% were not current smokers, but only 46% met the recommended alcohol consumption guidelines. Hours worked, teaching load, school sector and teacher role were associated with one or more lifestyle behaviours after adjusting for the demographic variables. This study highlights the need for additional support to improve the health-related behaviours of teachers in NSW. Policymakers should recognize the negative impact of high workloads on teachers' health-related behaviours, increasing their risk of chronic disease.

Sport Participation for Academic Success: Evidence From the Longitudinal Study of Australian Children.

BACKGROUND: We aimed to identify long-term patterns of sport participation (overall, team, and individual sport) from childhood into adolescence, and to examine the association between these patterns and academic outcomes. METHODS: This cohort study used data from the Longitudinal Study of Australian Children in wave 3 (4-5 y) to wave 9 (20-21 y). The participants were a nationally representative sample of 4241 children. We conducted latent class analyses to identify sport participation trajectories and assessed the association between these trajectories and academic outcomes. RESULTS: Continued sport participation was associated with lower odds of being absent from school (OR = 0.44; 95% confidence intervals [CIs], 0.26 to 0.74), better performance on attention (B = -0.010; 95% CIs, -0.019 to -0.002) and working memory (B = -0.013; 95% CIs, -0.023 to -0.003), higher numeracy (B = 20.21; 95% CIs, 14.56 to 25.86) and literacy scores (B = 9.42; 95% CIs, 2.82 to 16.02), higher end of school academic performance (B = 3.28; 95% CIs, 1.47 to 5.09), and higher odds of studying at university (OR = 1.78; 95% CIs, 1.32 to 2.40). Team sport participation was associated with reduced absenteeism, better performance on attention and working memory, and being awarded the Higher School Certificate. Whereas individual sport participation was associated with higher literacy scores and end of school academic performance. CONCLUSIONS: Team and individual sport participation both benefit academic outcomes, but differently. Given the decline in sport participation during adolescence, these findings highlight the need to develop educational policies to establish an environment that promotes sport participation, which in turn could improve academic outcomes.

A Model of Social Media Effects in Public Health Communication Campaigns: Systematic Review.

BACKGROUND: Social media platforms are frequently used in health communication campaigns. Common understandings of campaign effects posit a sequential and linear series of steps from exposure to behavior change, commonly known as the hierarchy of effects model (HOE). These concepts need to be reevaluated in the age of social media, which are interactional and communal. OBJECTIVE: This review aims to update the traditional HOE for health communication campaigns in the context of social media, including identifying indicators of effectiveness and how these are conceptualized to lead to health-related outcomes. METHODS: We conducted a systematic review of studies following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines reporting on the use of social media as part of health communication campaigns, extracting campaign information such as objectives, platforms used, and measures of campaign performance. We used these data, combined with our understanding of the HOE, to develop an updated conceptual model of social media campaign effects. RESULTS: We identified 99 eligible studies reporting on 93 campaigns, published between 2012 and 2022. The campaigns were conducted in over 20 countries, but nearly half (n=42) were conducted in the United States. Campaigns targeted a variety of health issues and predominantly used Facebook, Twitter, Instagram, and YouTube. Most campaigns (n=81) set objectives targeting awareness or individual behavior change. Process measures (n=68; eg, reach and impressions) and engagement measures (n=73; eg, likes and retweets) were reported most frequently, while two-fifths (n=42) did not report any outcomes beyond engagement, such as changes in knowledge, behavior, or social norms. Most campaigns (n=55) collected measures that did not allow them to determine if the campaign objective had been met; that is, they were process evaluations only. Based on our review, our updated model suggests that campaign exposure can lead to individual behavior change and improved health outcomes, either through a direct or indirect pathway. Indirect pathways include exposure through social and policy changes. "Engagement" is positioned as critical to success, replacing awareness in the traditional HOE, and all types of engagement are treated as equal and good. No consideration is being given to potential negative engagement, such as the distribution of misinformation. Additionally, the process is no longer linear and sequential, with circular pathways evident, such as engagement not only influencing behavior change but also generating additional exposure to campaign messages. CONCLUSIONS: Our review has highlighted a change in conventional understandings of how campaigns can influence health outcomes in the age of social media. The updated model we propose provides social media campaigners with a starting point to develop and tailor campaign messages and allows evaluators to identify critical assumptions to test, including the role and value of "engagement."

Lifestyle and work-related correlates of psychosocial health among Australian teachers: a cross-sectional study.

Aim: This study examined the psychosocial (psychological distress, job-specific wellbeing, burnout) health of a large sample of teachers in New South Wales (NSW), Australia, specifically the association between psychosocial health, work-related factors, and lifestyle behaviours. Subject & methods: An online survey collected lifestyle behaviours, work-related factors, and socio-demographics from primary and secondary school teachers in NSW from February to October 2021. Associations between work-related factors, lifestyle behaviours, and psychosocial health were modelled using logistic regression in R and adjusted for gender, age, and geographic location. Results: In our sample (n = 1136), 75% were women and 28% of the sample worked in rural or remote areas. Women reported higher levels of psychological distress (51%), compared with men (42%), and over 30% of teachers reported high levels of burnout. Teachers who engaged in three or more positive health-related behaviours had lower odds of psychological distress and burnout as well as higher odds of job-specific wellbeing. Multiple work-related factors such as hours worked, teaching load, teaching experience, teacher type, and teacher role were associated with one or more aspects of psychosocial health after adjusting for socio-demographic variables. Conclusion: More is needed to support the psychosocial health of teachers in NSW. Future lifestyle programs for this population should include psychosocial outcomes to further explore the relationship between teachers' health-related behaviour and their psychosocial health.

Combinations of Physical Activity, Sedentary Behavior, and Sleep Duration and Their Associations With Physical, Psychological, and Educational Outcomes in Children and Adolescents: A Systematic Review.

We conducted a systematic review to evaluate combinations of physical activity, sedentary behavior, and sleep duration (defined as "movement behaviors") and their associations with physical, psychological, and educational outcomes in children and adolescents. MEDLINE, CINAHL, PsychInfo, SPORTDiscus, PubMed, EMBASE, and ERIC were searched in June 2020. Included studies needed to 1) quantitatively analyze the association of 2 or more movement behaviors with an outcome, 2) analyze a population between 5 and 17 years of age, and 3) include at least an English abstract. We included 141 studies. Most studies included the combination of physical activity and sedentary behavior in their analyses. Sleep was studied less frequently. In combination, a high level of physical activity and a low level of sedentary behavior were associated with the best physical health, psychological health, and education-related outcomes. Sleep was often included in the combination that was associated with the most favorable outcomes. Sedentary behavior had a stronger influence in adolescents than in children and tended to be associated more negatively with outcomes when it was defined as screen time than when defined as overall time spent being sedentary. More initiatives and guidelines combining all 3 movement behaviors will provide benefit with regard to adiposity, cardiometabolic risk factors, cardiorespiratory fitness, muscular physical fitness, well-being, health-related quality of life, mental health, academic performance, and cognitive/executive function.

Creating healthy hospital retail food environments: Multiple pathways to successful at scale policy implementation in Australia.

OBJECTIVE: In 2017, the Australian state of New South Wales introduced a revised policy to provide a healthy food and drink environment for staff and visitors in the state's publicly funded health facilities. We sought to understand how contextual factors, intervention features and the responses of diverse stakeholders affected the policy's implementation in public hospitals. METHODS: Ninety-nine interviews were conducted with chief executives, implementers and retailers in the health and food retail systems after the target date for the implementation of 13 initial policy practices. Stakeholder responses were analysed to understand commitment to, engagement with and achievement of these practices and the different contexts and implementation approaches that prompted these responses. RESULTS: Key mechanisms that drove systemic change included stakeholders' broad acceptance of the policy premise; stakeholders' sense of accountability and desire for the policy to succeed; and the policy's perceived benefits, feasibility and effectiveness. Important underpinning factors were chief executives' commitment to implementation and monitoring, a flexible approach to locally tailored implementation and historical precedents. CONCLUSIONS: This study provides policy and practice insights for the initial phase of state-wide implementation to achieve change in health facility food retail environments.

Co-Produce, Co-Design, Co-Create, or Co-Construct-Who Does It and How Is It Done in Chronic Disease Prevention? A Scoping Review.

Co-production in health literature has increased in recent years. Despite mounting interest, numerous terms are used to describe co-production. There is confusion regarding its use in health promotion and little evidence and guidance for using co-produced chronic disease prevention interventions in the general population. We conducted a scoping review to examine the research literature using co-production to develop and evaluate chronic disease prevention programs. We searched four electronic databases for articles using co-production for health behaviour change in smoking, physical activity, diet, and/or weight management. In 71 articles that reported using co-production, co-design, co-create, co-develop, and co-construct, these terms were used interchangeably to refer to a participatory process involving researchers, stakeholders, and end users of interventions. Overall, studies used co-production as a formative research process, including focus groups and interviews. Co-produced health promotion interventions were generally not well described or robustly evaluated, and the literature did not show whether co-produced interventions achieved better outcomes than those that were not. Uniform agreement on the meanings of these words would avoid confusion about their use, facilitating the development of a co-production framework for health promotion interventions. Doing so would allow practitioners and researchers to develop a shared understanding of the co-production process and how best to evaluate co-produced interventions.

Reporting physical activity in minutes not bouts: findings from a survey in Australia.

OBJECTIVE: Physical activity has been commonly measured as time spent in bouts of at least 10 minutes, however, each minute of physical activity achieved in a day is now regarded as beneficial. This study aims to compare differences in total time spent walking in a week to time spent walking in 10-minute bouts over the same seven-day period. METHODS: Two self-reported measures of time spent walking were compared: one using time-constrained bouts and the other using total minutes. The first measure comes from the validated Active Australia Survey and reports walking in bouts of 10min or more, the second measure reports total estimated time spent walking. RESULTS: Data from 4,582 university participants in a census-styled survey were analysed. When comparing the reported minutes of walking in either 10-minute bouts or total minutes, more walking occurs in short bursts with a difference of 117min/week (p<0.001). CONCLUSIONS: This result shows more walking is reported across a week in short bursts of less than 10 minutes. Implications for public health: To monitor trends and evaluate physical activity interventions, reliable and valid measures of physical activity are necessary. Our result questions the usefulness of reporting bouted-walking as a measure which accurately captures population behaviour.
