Copenhagen consensus statements on workplace health enhancing physical activity programmes
Workplace health enhancing physical activity (HEPA) programmes are associated with physical activity promotion and reduction of sedentary time among employees. Whilst the workplace is often considered an appropriate setting for such programmes, however, ethical and implementation challenges remain. Furthermore, debate still exists concerning programme rationale, efficacy, effectiveness, and impact. In 2024, 24 researchers from twelve countries co…
Worldwide trends in underweight and obesity from 1990 to 2022: A pooled analysis of 3663 population-representative studies with 222 million children, adolescents, and adults
BACKGROUND: Underweight and obesity are associated with adverse health outcomes throughout the life course. We estimated the individual and combined prevalence of underweight or thinness and obesity, and their changes, from 1990 to 2022 for adults and school-aged children and adolescents in 200 countries and territories. METHODS: ). For school-aged children and adolescents, we report thinness (BMI 2 SD above the median). FINDINGS: From 1990 to 20…
Co-Creation of a School-Based Motor Competence and Mental Health Intervention: Move Well, Feel Good
Low motor competence (MC) and inhibited psychosocial development are associated with mental health difficulties. Improving children's MC through school-based physical activity interventions emphasising psychosocial development may therefore be a mechanism for promoting positive mental health. This study describes and provides reflective insights into the co-creation of 'Move Well Feel Good', a primary school physical activity intervention to impr…
Stakeholder perceptions of physical literacy assessment in primary school children
Background UNESCO [(2015). Quality Physical Education Guidelines for Policymakers. Paris: UNESCO Press.] highlighted the importance of developing physical literacy (PL) from childhood, although it remains unclear how best to evidence an individual’s PL journey. The aim of this study was to explore key stakeholders’ views of current practice, future directions and effective implementation of PL assessment, with a view to informing the development …
The Physical Behaviour Intensity Spectrum and Body Mass Index in School-Aged Youth: A Compositional Analysis of Pooled Individual Participant Data
We examined the compositional associations between the intensity spectrum derived from incremental acceleration intensity bands and the body mass index (BMI) z-score in youth, and investigated the estimated differences in BMI z-score following time reallocations between intensity bands. School-aged youth from 63 schools wore wrist accelerometers, and data of 1453 participants (57.5% girls) were analysed. Nine acceleration intensity bands (range: …

Height and body-mass index trajectories of school-aged children and adolescents from 1985 to 2019 in 200 countries and territories: A pooled analysis of 2181 population-based studies with 65 million p…
BACKGROUND: Comparable global data on health and nutrition of school-aged children and adolescents are scarce. We aimed to estimate age trajectories and time trends in mean height and mean body-mass index (BMI), which measures weight gain beyond what is expected from height gain, for school-aged children and adolescents. METHODS: For this pooled analysis, we used a database of cardiometabolic risk factors collated by the Non-Communicable Disease …
Rising rural body-mass index is the main driver of the global obesity epidemic in adults
Body-mass index (BMI) has increased steadily in most countries in parallel with a rise in the proportion of the population who live in cities 1,2 . This has led to a widely reported view that urbanization is one of the most important drivers of the global rise in obesity 3–6 . Here we use 2,009 population-based studies, with measurements of height and weight in more than 112 million adults, to report national, regional and global trends in mean B…
Calibration and Validation of the Youth Activity Profile as a Physical Activity and Sedentary Behaviour Surveillance Tool for English Youth
Self-reported youth physical activity (PA) is typically overestimated. We aimed to calibrate and validate a self-report tool among English youth. Four-hundred-and-two participants (aged 9-16 years; 212 boys) wore SenseWear Armband Mini devices (SWA) for eight days and completed the self-report Youth Activity Profile (YAP) on the eighth day. Calibration algorithms for temporally matched segments were generated from the YAP data using quantile regr…
Exploring Gender Differences within Forest Schools as a Physical Activity Intervention
This study investigated whether children engaged in more physical activity (PA) on school days that included Forest School (FS) sessions than a regular school day or a school day with a Physical Education (PE) lesson. How FS sessions influenced children's general levels of PA and wellbeing was also explored across gender. A mixed-methods study followed a sample of 59 child participants aged 7 to 9 years old, from four primary schools, whilst taki…
Establishing Raw Acceleration Thresholds to Classify Sedentary and Stationary Behaviour in Children
This study aimed to: (1) compare acceleration output between ActiGraph (AG) hip and wrist monitors and GENEActiv (GA) wrist monitors; (2) identify raw acceleration sedentary and stationary thresholds for the two brands and placements; and (3) validate the thresholds during a free-living period. Twenty-seven from 9- to 10-year-old children wore AG accelerometers on the right hip, dominant- and non-dominant wrists, GA accelerometers on both wrists,…

BACKGROUND: Underweight, overweight, and obesity in childhood and adolescence are associated with adverse health consequences throughout the life-course. Our aim was to estimate worldwide trends in mean body-mass index (BMI) and a comprehensive set of BMI categories that cover underweight to obesity in children and adolescents, and to compare trends with those of adults. METHODS: We pooled 2416 population-based studies with measurements of height…
One Size Does Not Fit All: Contextualising Family Physical Activity Using a Write, Draw, Show and Tell Approach
Understanding family physical activity (PA) behaviour is essential for designing effective family-based PA interventions. However, effective approaches to capture the perceptions and "lived experiences" of families are not yet well established. The aims of the study were to: (1) demonstrate how a "write, draw, show and tell" (WDST) methodological approach can be appropriate to family-based PA research, and (2) present two distinct family case stu…
Fitness, Fatness and Active School Commuting among Liverpool Schoolchildren
This study investigated differences in health outcomes between active and passive school commuters, and examined associations between parent perceptions of the neighborhood environment and active school commuting (ASC). One hundred-ninety-four children (107 girls), aged 9-10 years from ten primary schools in Liverpool, England, participated in this cross-sectional study. Measures of stature, body mass, waist circumference and cardiorespiratory fi…
Context matters! sources of variability in weekend physical activity among families: A repeated measures study
These novel findings enhance understanding of the variability and characteristics of weekend PA among family units. The study demonstrates the utility of PA diaries in conjunction with accelerometers to provide understanding of the mode and contexts of out-of-school and family-based PA
Utility of three anthropometric indices in assessing the cardiometabolic risk profile in children
Findings suggest that WHtR provides similar cardiometabolic risk estimates to age and sex adjusted BMI
Write, draw, show, and tell: A child-centred dual methodology to explore perceptions of out-of-school physical activity
Parents are in a unique position to promote health promoting behaviours serving as role models, physical activity gatekeepers and choice architects. Given the strong socialising effect parents have on children's physical activity, family-based physical activity intervention may offer a promising alternative compared to traditional school-based approaches. Parents' qualitative input is important to supplement children's voices and inform future fa…
Physical activity guidelines and cardiovascular risk in children: A cross sectional analysis to determine whether 60 minutes is enough
Achievement of current guidelines has positive effects on body composition and cardiorespiratory fitness, but not CCVR. Vigorous physical activity appears to have beneficial effects on CVD risk, independent of moderate PA, implying a more prescriptive approach may be needed for future VPA guidelines
Independent associations between cardiorespiratory fitness, waist circumference, BMI, and clustered cardiometabolic risk in adolescents
OBJECTIVES: The purpose of this study was to examine the independent associations between measures of adiposity and cardiorespiratory fitness (CRF) with clustered cardiometabolic risk in adolescents. METHODS: 209 adolescents (139 boys), aged 15-17.5 years participated. Participants completed anthropometric measurements [height, weight, waist circumference (WC)] whilst the 20 m fitness test was used to assess CRF. Additional measures included syst…

Is Air Temperature at Birth Associated with Body Mass Index in 9–10 Year-Old Children
Several studies suggest that temperature (season) at birth affects body weight and obesity years later. This study related air temperature at birth to body mass index in Liverpool primary school children (n = 11,084). No association was found between body mass index categories and month or season of birth and only weak correlations with month of birth and air temperature at birth. These correlations disappeared when controlled for precise age and…
