Abstract: We used a prevalence-based approach to estimate the economic costs associated with low muscle strength, as assessed using handgrip strength, in Canadian adults. We estimated the annual economic burden of low muscle strength at $3.0 billion, representing 2.2% of the 2021 Canadian burden of illness costs. The two most expensive chronic diseases attributable to low muscle strength were cardiovascular disease ($899 million) and type 2 diabetes ($880 million). A 10% decrease in the prevalence of low handgrip strength would save approximately $546 million per year, equivalent to an 18.1% cost reduction. Strategies to increase population-level muscle strength are needed to reduce healthcare costs and improve health. The economic cost associated with low muscle strength in Canadian adults is unknown. The total annual economic burden of low muscle strength in Canadian adults represents 2.2% of the overall burden of illness costs in 2021. We estimated that $546 million per year would be saved if the prevalence of low handgrip strength was reduced by 10%.

Abstract: Political and legal debate about freedom of religion and belief (FoRB) in Australia has intensified since the Same-sex marriage postal survey in 2017. Central to this debate has been children, their parents and institutions (Schools). This paper outlines the place of children in the Australian FoRB since 2017, focusing on the Same-sex marriage postal survey debate and subsequent reviews into freedom of religion. In particular it highlights the links drawn between same-sex marriage or marriage equality and the Safe School Coalition Australia c aign, the emphasis on parental rights in relation to education about marriage in schools and the ongoing debate about potential reform to Australia’s suit of anti-discrimination laws

Abstract: We investigated whether associations of neighborhood social environment attributes and physical activity differed among 12 countries and levels of economic development using World Bank classification (low/lower-middle-, upper-middle- and high- income countries) among 9-11 year old children (N=6161) from the International Study of Childhood Obesity, Lifestyle, and the Environment (ISCOLE). Collective efficacy and perceived crime were obtained via parental/guardian report. Moderate-to-vigorous physical activity (MVPA) was assessed with waist-worn Actigraph accelerometers. Neighborhood environment by country interactions were tested using multi-level statistical models, adjusted for covariates. Effect estimates were reported by country and pooled estimates calculated across World Bank classifications for economic development using meta-analyses and forest plots. Associations between social environment attributes and MVPA varied among countries and levels of economic development. Associations were more consistent and in the hypothesized directions among countries with higher levels economic development, but less so among countries with lower levels of economic development.

Abstract: Whether outdoor time is linked to dietary patterns of children has yet to be empirically tested. The objective of this study was to examine the association between outdoor time and dietary patterns of children from 12 countries around the world. This multinational, cross-sectional study included 6229 children 9–11 years of age. Children self-reported the time that they spent outside before school, after school and on weekends. A composite score was calculated to reflect overall daily outdoor time. Dietary patterns were assessed using a food frequency questionnaire, and two components were used for analysis: healthy and unhealthy dietary pattern scores. On average, children spent 2.5 h outside per day. After adjusting for age, sex, parental education, moderate-to-vigorous physical activity, screen time and body mass index z-score, greater time spent outdoors was associated with healthier dietary pattern scores. No association was found between outdoor time and unhealthy dietary pattern scores. Similar associations between outdoor time and dietary patterns were observed for boys and girls and across study sites. Greater time spent outside was associated with a healthier dietary pattern in this international s le of children. Future research should aim to elucidate the mechanisms behind this association.

Abstract: No studies have examined if mid-upper arm circumference (MUAC) can be an alternative screening tool for obesity in an international s le of children differing widely in levels of human development. Our aim is to determine whether MUAC could be used to identify obesity in children from 12 countries in five major geographic regions of the world. This observational, multinational cross-sectional study included 7337 children aged 9-11 years. Anthropometric measurements were objectively assessed, and obesity was defined according to the World Health Organization reference data. In the total s le, MUAC was strongly correlated with adiposity indicators in both boys and girls (r > 0.86, p < 0.001). The accuracy level of MUAC for identifying obesity was high in both sexes and across study sites (overall area under the curve of 0.97, sensitivity of 95% and specificity of 90%). The MUAC cut-off value to identify obesity was ~25 cm for both boys and girls. In country-specific analyses, the cut-off value to identify obesity ranged from 23.2 cm (boys in South Africa) to 26.2 cm (girls in the UK). Results from this 12-country study suggest that MUAC is a simple and accurate measurement that may be used to identify obesity in children aged 9-11 years. MUAC may be a promising screening tool for obesity in resource-limited settings.

Abstract: The direction of the association between discretionary screen time (DST) and sleep in the adult population is largely unknown. We examined the bidirectional associations of DST and sleep patterns in a longitudinal s le of adults in the general population. A total of 31,361 UK Biobank study participants (52% female, 56.1 ± 7.5 years) had two repeated measurements of discretionary screen time (TV viewing and leisure‐time computer use) and self‐reported sleep patterns (five sleep health characteristics) between 2012 and 2018 (follow‐up period of 6.9 ± 2.2 years). We categorised daily DST into three groups (low, h/day medium, 3–4 h/day and high, h/day), and calculated a sleep pattern composite score comprising morning chronotype, adequate sleep duration (7–8 h/day), never or rare insomnia, never or rare snoring, and infrequent daytime sleepiness. The overall sleep pattern was categorised into three groups (healthy: ≥ 4 intermediate: 2–3 and poor: ≤ 1 healthy sleep characteristic). Multiple logistic regression analyses were applied to assess associations between DST and sleep with adjustments for potential confounders. Participants with either an intermediate (OR: 1.40 95% CI: 1.15, 1.71) or a poor (OR: 1.16 95% CI: 1.10, 1.24) sleep pattern at baseline showed higher odds for high DST at follow‐up, compared with those with a healthy baseline sleep pattern. Participants with medium (OR: 1.40 95% CI: 1.14, 1.71) or high DST (OR: 1.62 95% CI: 1.30, 2.00) at baseline showed higher odds for poor sleep at follow‐up, compared with participants with a low DST. In conclusion, our findings provide consistent evidence that a high DST at baseline is associated with poor sleep over a nearly 7 year follow‐up period, and vice versa.

Abstract: This study investigated associations between weather conditions, physical activity, and sedentary time in primary school-aged children in Australia and Canada. Cross-sectional data on 9–11-year-old children from the Australian ( n = 491) and Canadian ( n = 524) sites of the International Study of Childhood Obesity, Lifestyle and the Environment were used. Minutes of daily moderate-to-vigorous-physical-activity (MVPA) and sedentary time were determined from 7-day, 24-h accelerometry (Actigraph GT3X+ triaxial accelerometer). Day-matched weather data (temperature, rainfall, snowfall, relative humidity, wind speed) were obtained from the closest weather station to participants’ schools. Covariates included parental highest education level, day type, sex, and BMI z-scores. Generalized mixed model analyses allowing for clustering of participants within schools were completed. Scatterplots with Loess curves were created for maximum temperature, MVPA, and sedentary time. Daily maximum temperature was significantly associated with MVPA and sedentary time in Australia (MVPA p = .05, sedentary p = .01) and Canada ( p .001, p = .001). Rainfall was negatively associated with MVPA in Australia ( p .001) and positively associated with sedentary time in Canada ( p = .02). MVPA and sedentary time appear to be optimal when the maximum temperature ranges between 20°C and 25°C in both countries. The findings have implications for study design and interpretation for surveillance and intervention studies.

Abstract: To describe new WHO 2020 guidelines on physical activity and sedentary behaviour. The guidelines were developed in accordance with WHO protocols. An expert Guideline Development Group reviewed evidence to assess associations between physical activity and sedentary behaviour for an agreed set of health outcomes and population groups. The assessment used and systematically updated recent relevant systematic reviews new primary reviews addressed additional health outcomes or subpopulations. The new guidelines address children, adolescents, adults, older adults and include new specific recommendations for pregnant and postpartum women and people living with chronic conditions or disability. All adults should undertake 150–300 min of moderate-intensity, or 75–150 min of vigorous-intensity physical activity, or some equivalent combination of moderate-intensity and vigorous-intensity aerobic physical activity, per week. Among children and adolescents, an average of 60 min/day of moderate-to-vigorous intensity aerobic physical activity across the week provides health benefits. The guidelines recommend regular muscle-strengthening activity for all age groups. Additionally, reducing sedentary behaviours is recommended across all age groups and abilities, although evidence was insufficient to quantify a sedentary behaviour threshold. These 2020 WHO guidelines update previous WHO recommendations released in 2010. They reaffirm messages that some physical activity is better than none, that more physical activity is better for optimal health outcomes and provide a new recommendation on reducing sedentary behaviours. These guidelines highlight the importance of regularly undertaking both aerobic and muscle strengthening activities and for the first time, there are specific recommendations for specific populations including for pregnant and postpartum women and people living with chronic conditions or disability. These guidelines should be used to inform national health policies aligned with the WHO Global Action Plan on Physical Activity 2018–2030 and to strengthen surveillance systems that track progress towards national and global targets.

Abstract: Research examining the associations between movement behaviours and mental health indicators within a compositional framework are sparse and limited by their cross-sectional study design. This study has three objectives. First, to describe the change in movement behaviour composition over time. Second, to explore the association between change in movement behaviour composition and change in depressive symptoms. Third, to explore how reallocations of time between movement behaviours are associated with changes in depressive symptoms. Longitudinal data of 14,620 students in grades 9–12 (mean age: 14.9 years) attending secondary schools in Canada (Ontario, British Columbia, Alberta, Quebec) were obtained from two waves (2017/18, 2018/19) of the COMPASS study. Moderate-to-vigorous physical activity (MVPA), recreational screen time, and sleep duration were self-reported. Depressive symptoms were measured using the Center for Epidemiologic Studies Depression Scale (Revised)−10 (CESD-R-10). Compositional data analyses using pivot coordinates and compositional isotemporal substitution for longitudinal data were used to analyse the data. Analyses accounted for school clustering, were stratified by gender and age ( or ≥ 15 years), and were adjusted for race/ethnicity, body mass index z-score, baseline movement behaviour composition, and baseline depressive symptoms. There were significant differences in movement behaviour composition over time across all subgroups. For ex le, the relative contributions of MVPA and sleep duration to the movement behaviour composition decreased over time while screen time increased among younger boys and girls and older girls. Increasing sleep duration relative to the remaining behaviours (i.e. screen time and MVPA) was associated with lower depressive symptoms among all subgroups. Increasing screen time relative to the remaining behaviours (i.e. MVPA and sleep duration) was associated with higher depressive symptoms among all subgroups. Increasing MVPA relative to the remaining behaviours (i.e. screen time and sleep duration) was associated with lower depressive symptoms in older girls only. Isotemporal substitution estimates indicated that decreasing screen time by 60 minutes/day and replacing that time with 60 minutes of additional sleep is associated with the largest change in depressive symptoms across all subgroups. Findings from this prospective analysis suggest that increased sleep duration and reduced screen time are important determinants of lower depressive symptoms among adolescents.

Abstract: To evaluate the relationship between children's lifestyles and health-related quality of life and to explore whether this relationship varies among children from different world regions. This study used cross-sectional data from the International Study of Childhood Obesity, Lifestyle and the Environment. Children (9-11 years) were recruited from sites in 12 nations (n = 5759). Clustering input variables were 24-hour accelerometry and self-reported diet and screen time. Health-related quality of life was self-reported with KIDSCREEN-10. Cluster analyses (using compositional analysis techniques) were performed on a site-wise basis. Lifestyle behavior cluster characteristics were compared between sites. The relationship between cluster membership and health-related quality of life was assessed with the use of linear models. Lifestyle behavior clusters were similar across the 12 sites, with clusters commonly characterized by (1) high physical activity (actives) (2) high sedentary behavior (sitters) (3) high screen time/unhealthy eating pattern (junk-food screenies) and (4) low screen time/healthy eating pattern and moderate physical activity/sedentary behavior (all-rounders). Health-related quality of life was greatest in the all-rounders cluster. Children from different world regions clustered into groups of similar lifestyle behaviors. Cluster membership was related to differing health-related quality of life, with children from the all-rounders cluster consistently reporting greatest health-related quality of life at sites around the world. Findings support the importance of a healthy combination of lifestyle behaviors in childhood: low screen time, healthy eating pattern, and balanced daily activity behaviors (physical activity and sedentary behavior).

Abstract: Veganism, where adherents eschew the consumption of animals or their by-products, has seen a substantial increase in popularity in recent years. Vegans who follow the diet for moral or ethical reasons (ethical vegans) have argued in the United States, with limited success and, more recently, in the United Kingdom that they should be protected from discrimination on the grounds of their adherence to ethical veganism, contending that ethical veganism should be subject to similar protections as religion. In the United Kingdom, anti-discrimination legislation protects philosophical beliefs in addition to religion and it was recently held in a preliminary hearing in Casamitjana v The League Against Cruel Sports that ethical veganism falls within the ambit of the relevant statute. The authors examine the situation in the United Kingdom and the United States and conclude that, given that Australian anti-discrimination statutes only refer to religion as a protected attribute, this outcome is unlikely to be replicated since veganism is highly unlikely to meet the current definition of religion.

Abstract: To explore the correlates of nocturnal sleep duration, nocturnal sleep variability, and nocturnal sleep problems in a s le of Australian toddlers. Participants were 173 toddlers (average age 19.7 ± 4.1 months) from the GET UP! Nocturnal sleep duration, nocturnal sleep variability, nap(s) and physical activity were measured using 24-h accelerometry (Actigraph GT3X+) over seven consecutive days. Nocturnal sleep problems were assessed using the Tayside Children's Sleep Questionnaire. Screen time was reported by the parents. Logistic regression models were used to examine the associations between potential correlates (ie, age, sex, socio-economic status, weight status, physical activity, screen time, nap(s), bedtimes, and wake-up times) and nocturnal sleep characteristics. Older children were more likely to have greater sleep variability (OR: 1.97 95% CI: 1.08-3.61). Less physical activity (OR: 2.38 95% CI: 1.27-4.45), shorter nap(s) (OR: 2.42, 95% CI: 1.29-4.55), and later wake-up times (OR: 4.42 95% CI: 2.32-8.42) were associated with higher odds of having longer nocturnal sleep duration. Late bedtimes were associated with shorter nocturnal sleep duration (OR: 0.09 95% CI: 0.04-0.18) and with greater nocturnal sleep variability (OR: 1.97 95% CI: 1.06-3.68). None of the potential correlates were associated with nocturnal sleep problems. The present study identifies several correlates of nocturnal sleep duration (total physical activity, nap(s), bedtime, and wake-up time) and nocturnal sleep variability (age and bedtime), whereas no correlates were identified for nocturnal sleep problems. The association between late bedtimes and shorter nocturnal sleep duration and greater nocturnal variability suggests that these may be modifiable targets for future sleep interventions in early childhood.

Abstract: Household factors (electronic media equipment, play equipment, physical activity in the home, and social support) have been associated with childhood moderate- to vigorous-intensity physical activity (MVPA), but little is known about how these factors differ across erse countries. The objective was to explore household correlates of objective MVPA in children from 12 countries. Overall, 5,859 nine- to eleven-year-old children from 12 countries representing a range of human and socioeconomic development indicators wore an accelerometer for 7 days and parents reported on household factors. Multilevel general linear models explored associations among household factors and MVPA variables controlling for age, sex, and parental education. Across sites, children with at least one piece of bedroom electronic media had lower MVPA (∼4 min/day P < 0.001) than those who did not. More frequent physical activity in the home and yard, ownership of more frequently used play equipment, and higher social support for physical activity were associated with more MVPA (all P < 0.001). The association between play equipment ownership and MVPA was inconsistent across countries (interaction P < 0.01). With the exception of play equipment ownership, modifiable household factors showed largely consistent and important associations with MVPA across high-, mid-, and low-income countries.

Abstract: The relationship between the state and religion in Australia exists in a state of tension. On the one hand the “non-establishment” clause in section 116 of the Australian Constitution points to the separation of religion and state. On the other hand there is a high level of cooperation between the state and religion in the public sphere, most visible in the funding of religious schools by the federal government. These two visions of the Australian state-religion relationship are in tension. One requiring the removal of religion from the public sphere while the other calls for a plurality of religions to be accommodated in public spaces. This article seeks to resolve this tension by proposing a new way to understand the Australian state-religion relationship as non-establishment pluralism . Non-establishment in the sense that the Australian Constitution prohibits the establishment of any religion—be that a single state church, multiple state religions, or religion generally. Pluralism in that the state via ordinary legislation, public policy, and government action cooperates with religion in numerous areas of state and religious interest in the public sphere.

Abstract: Humanity has a weakness in how we approach the “challenge” of using outer space. This paper aims to show how the global and national frameworks that address our planetary activities and crises are inadequate for the opportunities and challenges of life in outer space. The authors draw on multidisciplinary perspectives to refine an organising governance framework that better showcases the challenges and pathways needed for living and thriving in space-age. The authors prioritise two key pillars and overview the practical and social implications that space-age humanity must address. Social sciences and humanities are vital to problematising post-war colonial legacies of governance by distinguishing the unique and overlooked challenges for thriving and working offworld and identifying progressive research agendas. The highlighted agenda has implications for collaborative research institutes and project design. As the vital basis for continuous learning, university-based research institutes span bodies of knowledge, experience, convention and imagination that can support vibrant and overdue debate on good governance that is out of this world. This expansive approach has practical implications for the decision-making processes and subjects of spacescape, from reconciling the space commons with prospecting and human occupation to potential governance regimes that capitalise on the zeal for moving beyond merely “existing” off-world. Examining the governance deficit as we pursue developing spacescape frontiers is an enriching (not reductionist) agenda that deliberately troubles the existing and emerging regime for governing our scientific and imagined off-world society. This framework appeals to humanity’s highest evolution in co-producing a fair and flourishing off-world governance framework (beyond replicating planetary regimes).

Abstract: To examine the relationships between socioeconomic status (SES household income and parental education) and objectively measured sleep patterns (sleep duration, sleep efficiency, and bedtime) among children from around the world and explore how the relationships differ across country levels of human development. Multinational, cross-sectional study from sites in Australia, Brazil, Canada, China, Colombia, Finland, India, Kenya, Portugal, South Africa, the United Kingdom, and the United States. The International Study of Childhood Obesity, Lifestyle and the Environment. A total of 6040 children aged 9-11 years. Sleep duration, sleep efficiency, and bedtime were monitored over 7 consecutive days using waist-worn accelerometers. Multilevel models were used to examine the relationships between sleep patterns and SES. In country-specific analyses, there were no significant linear trends for sleep duration and sleep efficiency based on income and education levels. There were significant linear trends in 4 countries for bedtime (Australia, United States, United Kingdom, and India), generally showing that children in the lowest income group had later bedtimes. Later bedtimes were associated with lowest level of parental education in only 2 countries (United Kingdom and India). Patterns of associations between sleep characteristics and SES were not different between boys and girls. Sleep patterns of children (especially sleep duration and efficiency) appear unrelated to SES in each of the 12 countries, with no differences across country levels of human development. The lack of evidence for an epidemiological transition in sleep patterns suggests that efforts to improve sleep hygiene of children should not be limited to any specific SES level.

Abstract: The purpose of this study was to examine whether meeting movement behavior recommendations (i.e., ≥60 min of moderate-to-vigorous physical activity [MVPA] per day, ≤2 h of recreational screen time per day, and between 9 and 11 h of nightly sleep), and combinations of these recommendations, are associated with dietary patterns of children. This cross-sectional study was conducted between 2011 and 2013 and included 5873 children 9-11 years of age from 12 countries around the world. MVPA and nightly sleep duration were measured using 24-hour waist-worn accelerometry. Screen time habits were assessed via self-report. A food frequency questionnaire was used to assess dietary patterns, and the whole diet was described by two components derived from principal component analysis: "healthy" and "unhealthy" dietary pattern scores. Covariates included in the multilevel statistical models included age, sex, highest parental education, and body mass index z-score. A healthier dietary pattern score was observed when more movement behavior recommendations were met. Among the three movement behaviors, limiting screen time habits to the recommended amount was most strongly associated with healthier dietary patterns. Similarly, a less unhealthy dietary pattern was observed when more movement behavior recommendations were met. Surprisingly, the highest unhealthy dietary pattern was associated with children meeting the MVPA recommendation alone. Combinations including ≤2 h of screen time per day were those most strongly associated with a less unhealthy dietary pattern. Findings were similar across study sites and in boys and girls. In conclusion, meeting more movement behavior recommendations is generally associated with better dietary patterns in children from around the world, with limiting screen time habits showing the strongest relationships.

Abstract: The incidence of infectious complications, compared with the general population and the pre-transplant status of the recipient, increases substantially following kidney transplantation, causing significant morbidity and mortality. The potent immunosuppressive therapy given to prevent graft rejection in kidney transplant recipients results in an increased susceptibility to a wide range of opportunistic infections including bacterial, viral and fungal infections. Over the last five years, several advances have occurred that may have changed the burden of infectious complications in kidney transplant recipients. Due to the availability of direct-acting antivirals to manage donor-derived hepatitis C infection, this has opened the way for donors with hepatitis C infection to be considered in the donation process. In addition, there have been the development of medications targeting the growing burden of resistant cytomegalovirus, as well as the discovery of the potentially important role of the gastrointestinal microbiota in the pathogenesis of post-transplant infection. In this narrative review, we will discuss these three advances and their potential implications for clinical practice.

Abstract: Leaders from the Canadian Society for Exercise Physiology convened representatives of national organizations, content experts, methodologists, stakeholders, and end-users who followed rigorous and transparent guideline development procedures to create the Canadian 24-Hour Movement Guidelines for Children and Youth: An Integration of Physical Activity, Sedentary Behaviour, and Sleep. These novel guidelines for children and youth aged 5–17 years respect the natural and intuitive integration of movement behaviours across the whole day (24-h period). The development process was guided by the Appraisal of Guidelines for Research Evaluation (AGREE) II instrument and systematic reviews of evidence informing the guidelines were assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. Four systematic reviews (physical activity, sedentary behaviour, sleep, integrated behaviours) examining the relationships between and among movement behaviours and several health indicators were completed and interpreted by expert consensus. Complementary compositional analyses were performed using Canadian Health Measures Survey data to examine the relationships between movement behaviours and health indicators. A stakeholder survey was employed (n = 590) and 28 focus groups/stakeholder interviews (n = 104) were completed to gather feedback on draft guidelines. Following an introductory preamble, the guidelines provide evidence-informed recommendations for a healthy day (24 h), comprising a combination of sleep, sedentary behaviours, light-, moderate-, and vigorous-intensity physical activity. Proactive dissemination, promotion, implementation, and evaluation plans have been prepared in an effort to optimize uptake and activation of the new guidelines. Future research should consider the integrated relationships among movement behaviours, and similar integrated guidelines for other age groups should be developed.

Abstract: The relationship between children's adiposity and lifestyle behaviour patterns is an area of growing interest. The objectives of this study are to identify clusters of children based on lifestyle behaviours and compare children's adiposity among clusters. Cross-sectional data from the International Study of Childhood Obesity, Lifestyle and the Environment were used. the participants were children (9-11 years) from 12 nations (n = 5710). 24-h accelerometry and self-reported diet and screen time were clustering input variables. Objectively measured adiposity indicators were waist-to-height ratio, percent body fat and body mass index z-scores. sex-stratified analyses were performed on the global s le and repeated on a site-wise basis. Cluster analysis (using isometric log ratios for compositional data) was used to identify common lifestyle behaviour patterns. Site representation and adiposity were compared across clusters using linear models. Four clusters emerged: (1) Junk Food Screenies, (2) Actives, (3) Sitters and (4) All-Rounders. Countries were represented differently among clusters. Chinese children were over-represented in Sitters and Colombian children in Actives. Adiposity varied across clusters, being highest in Sitters and lowest in Actives. Children from different sites clustered into groups of similar lifestyle behaviours. Cluster membership was linked with differing adiposity. Findings support the implementation of activity interventions in all countries, targeting both physical activity and sedentary time.

This study included 6106 children aged 9-11 years from sites in Australia, Brazil, Canada, China, Colombia, Finland, India, Kenya, Portugal, South Africa, the United Kingdom, and the United States. Participants completed the KIDSCREEN-10 to provide a global measure of their HRQoL. Sleep duration and MVPA were assessed using 24-h accelerometry. Screen time was assessed through self-report. Meeting the recommendations was defined as ≥60 min/day for MVPA, ≤2 h/day for screen time, and between 9 and 11 h/night for sleep duration. Age, sex, highest parental education, unhealthy diet pattern score, and body mass index z-score were included as covariates in statistical models. In the full s le, children meeting the screen time recommendation, the screen time + sleep recommendation, and all three recommendations had significantly better HRQoL than children not meeting any of these guidelines. Differences in HRQoL scores between sites were also found within combinations of movement/non-movement behaviors. For ex le, while children in Australia, Canada, and USA self-reported better HRQoL when meeting all three recommendations, children in Kenya and Portugal reported significantly lower HRQoL when meeting all three recommendations (relative to not meeting any). Self-reported HRQoL is generally higher when children meet established movement/non-movement recommendations. However, differences between study sites also suggest that interventions aimed at improving lifestyle behaviors and HRQoL should be locally and culturally adapted.

Abstract: The purpose of this review is to summarize the scientific contributions of the International Study of Childhood Obesity, Lifestyle and the Environment (ISCOLE) in extending our understanding about obesity in children from around the world. ISCOLE was a multi-national study of 9 to 11 year-old children from sites in 12 countries from all inhabited continents. The primary purpose was to investigate relationships between lifestyle behaviors and obesity, and the influence of higher-order characteristics such as behavioral settings, and physical, social and policy environments. ISCOLE has made several advances in scientific methodology related to the assessment of physical activity, dietary behavior, sleep and the neighborhood and school environments. Furthermore, ISCOLE has provided important evidence on (1) epidemiological transitions in obesity and related behaviors, (2) correlates of obesity and lifestyle behaviors at the in idual, neighborhood and school levels, and (3) 24-h movement behaviors in relation to novel analytical techniques. A key feature of ISCOLE was the development of a platform for international training, data entry, and data quality for multi-country studies. Finally, ISCOLE represents a transparent model for future public-private research partnerships across low, middle and high-income countries.

Abstract: The aim was to assess associations between lifestyle behaviors and obesity in a multinational study of children from 12 countries representing a wide range of human development. The s le included 6,025 children 9-11 years of age. Behavioral risk factors included nocturnal sleep duration, moderate to vigorous physical activity (MVPA), television viewing (TV time), and healthy and unhealthy diet pattern scores. Multilevel analyses were used to obtain odds ratios for obesity expressed per standard deviation of each behavioral risk factor. The odds ratios (95% confidence intervals) for obesity from multilevel, multivariable models were 0.79 (0.71-0.90) for nocturnal sleep duration, 0.52 (0.45-0.60) for MVPA, 1.15 (1.05-1.27) for TV time, 1.08 (0.96-1.20) for healthy diet score, and 0.93 (0.83-1.04) for unhealthy diet score in boys and 0.71 (0.63-0.80) for nocturnal sleep duration, 0.43 (0.35-0.53) for MVPA, 1.07 (0.96-1.19) for TV time, 1.05 (0.93-1.19) for healthy diet score, and 0.96 (0.82-1.11) for unhealthy diet score in girls. Behavioral risk factors are important correlates of obesity in children, particularly low MVPA, short sleep duration, and high TV viewing.

Abstract: The Commonwealth and all states and territories provide exemptions for religious organisations and schools from anti-discrimination laws. However, it is unclear how and when these exemptions are being used by religious organisations. This article argues that all religious organisations who rely on exemptions in anti-discrimination laws should be required to be transparent in their use.

Abstract: The purpose of this study was to describe children’s daily compliance with moderate-to-vigorous physical activity (MVPA) recommendations across a week in different parts of the world, and to identify in idual- and school-level correlates that may explain differences in daily MVPA compliance. The s le included 6553 children aged 9–11 years from 12 countries, and multilevel statistical analyses were used, including both child- and school-level variables. Most children did not comply with the MVPA guidelines on a daily basis: Chinese children complied the least, whereas Finnish, Australian, Colombian, UK, and Kenyan children complied the most. Boys (rate ratio [RR] = 1.47) and children with higher unhealthy diet scores (RR = 1.08) complied more, but overweight/obese children (RR = 0.81), earlier maturing children (RR = 0.93), and those who spent more time in screen activities (RR = 0.98) and sleeping (RR = 0.96) had the lowest compliance. At the school level, children with access to playground or sport equipment (RR = 0.88, for both) tended to comply less, whereas those with access to a gymnasium outside the school hours complied more with the MVPA guidelines (RR = 1.14). Significant between-country differences in children’s daily MVPA compliance were observed, reflecting not only site characteristics, but also the importance of in idual traits and local school contexts.
