The Impact and Future of Physical Activity Research
Purpose: To explore the impact of the 2012, 2016, 2021 The Lancet Physical Activity Series and provide an overview of the main results of an upcoming series.
Description: Publishing in The Lancet journal is particularly significant due to its visibility, extensive reach and considerable influence on public health and medical practice worldwide. As such, The Lancet Physical Activity Series of 2012, 2016, and 2021 provided a platform for wide dissemination of research findings on high-priority topics in the physical activity field. The overarching aim of the series was to advance the understanding and promotion of physical activity worldwide. This Symposium will include four presentations starting with a historical perspective and impact of The Lancet Physical Activity Series coupled with an overview of the three past series. Presentations 2-4 will follow with an overview of the new, forthcoming papers intended to be included in a 4th Lancet Physical Activity series. These presentations will delve into critical new topics including (a) health equity and a paradigm shift positing physical activity as not solely relevant to Non-Communicable Diseases (NCDs) but adopting a syndemics approach, (b) examining the nexus between physical activity and climate change/environmental sustainability, and (c) the importance of scaling up effective physical activity policies globally. Presentation one (Professor Pedro Hallal) will summarize key findings and contributions of the three series over the last decade and how the past series are positioned as a significant effort for advancing the science of physical activity and related fields. Presentation two (Associate Professor Deborah Salvo) will introduce the first paper of the 4th series exploring how the current age of syndemics presents interacting global crises of infectious diseases, NCDs, mental health problems, persistent health inequities, and climate change; all of which can benefit from physical activity. Presentation three (Professor Erica Hinckson) will reinforce the dual goal of bringing together the physical activity and climate agendas to address human and planetary health by urgently taking a multisectoral collaborative approach that will focus on comprehensive and holistic actions through policy change. Finally, Presentation four (Assistant Professor Andrea Ramirez Varela) will provide a critical reflection on monitoring global physical activity policies to assess progress in national and global physical activity and NCD prevention policies to guide efforts, inform decision-making, and drive actions aimed at fostering healthier populations and mitigating the prevalence of physical inactivity for the future.
This symposium will share learnings from research teams across six world regions with an emphasis on discussion, reflection and vision to guide the future of physical activity in the next decades to come.

Abstract 1: History and impact of The Lancet physical activity series (2012, 2016, 2021)
Background: In 2012, The Lancet introduced its inaugural series on Physical Activity (PA) during the 2012 Summer Olympic Games, shedding light on the alarming statistic that physical inactivity contributes to over 5 million global deaths annually, a figure equivalent to smoking-related deaths. Subsequent series in 2016 and 2021 emphasized the pressing need for addressing the substantial healthcare burden associated with physical inactivity, focusing on sedentary behaviour, disability, and at-risk populations.
Purpose: We explore the decade-long legacy of The Lancet PA series and leverage the insights gained to explore a new series.
Methods: Using bibliometric assessment and other methods we synthesized the accumulated knowledge and experience over the past decade and impact of the series on the physical activity and public health fields. Particularly, we explored citations, mentions, comparisons to other Lancet series, users by country and profession, and policy utilisation.
Results: The Lancet Series have profoundly impacted the physical activity and public health fields. In this presentation, we will elaborate on the nature of the impact on research, teaching and policy.
Conclusions: The legacy left by The Lancet PA series will provide the platform for a new direction in physical activity research that better informs policy and practice.
Practical implications: Lessons learnt are expected to have practical implications for public health, policy development, and international collaboration. The insights gained are well placed to inform evidence-based strategies for addressing global challenges through targeted interventions related to physical activity, and therefore contributing to the advancement of public health agendas worldwide.
Abstract 2: Reconceptualising physical activity for the age of syndemics using a global equity lens.
Background: The public health and medical communities generally recognise the importance of physical activity for preventing and controlling noncommunicable diseases (NCDs). However, its importance for addressing other major global issues is less well-recognised.
Purpose: This paper uses a global equity lens to shed light on the benefits of physical activity, above and beyond NCD prevention and control, for the age of syndemics (co-occurring pandemics and major global challenges).
Methods: Using nationally representative WHO data from 68 countries, we conducted a harmonized analysis of domain-specific physical activity for leisure, transport, and work; using equity plots and slope indices to quantify socioeconomic and gender-based inequalities. Next, we systematically scoped the literature of physical activity studies during the COVID-19 pandemic, as this recent global crisis underscored the public health relevance of physical activity for the age of syndemics.
Results: Pre-pandemic data revealed within- and between-country socioeconomic inequalities, with higher prevalence of leisure physical activity in higher-income countries and groups; and higher prevalence of utilitarian physical activity in lower-income countries and groups. Gender-based inequality data analysis is underway. The scoping reviews of COVID-19 and physical activity studies showed that (a) physical activity inequalities may have widened due to COVID-19; (b) physical activity was inversely associated with adverse COVID-19 related outcomes, underscoring the often-unrecognized importance of physical activity for infectious disease and immunity; and (c) physical activity may have buffered some of the negative mental health consequences of the COVID-19 pandemic, underscoring its mental health benefits.
Conclusions: The current age of syndemics is challenged by the global crises of infectious diseases and NCDs, mental health problems, persistent health inequalities, and climate change; all of which can benefit from physical activity.
Practical Implications: It is critical to reconceptualise physical activity as a factor with high relevance to multiple elements of modern-day syndemics.
Abstract 3: Living, moving, and playing on a sustainable and healthy planet: the urgency of combining physical activity and climate change agendas
Background: Climate change is the most dangerous self-inflicted catastrophe ever experienced by humanity, and physical inactivity is responsible for more than 5 million deaths per year worldwide.
Purpose: We have an opportunity to align and mobilise policy, research, and action toward the dual goals of mitigating climate change risks and promoting human health through physical activity.
Methods: We conceptualise the interconnection between frameworks on physical activity and climate change across ISPAH’s Strategies that Work for Physical Activity using applied systems thinking tools. We also address unintended consequences, consider inequities, and offer analytical frameworks for further research. Physical activity is in many ways reciprocally linked to climate change.
Results: Physical activity solutions can supplement the response to climate change. We propose a framework for action whereby advancing physical activity promotion can simultaneously reduce health and environmental inequities, mitigate climate change, and adapt both environment and behaviour long term for a changing climate.
Conclusions: Advancing physical activity and climate change agendas equitably must consider context and input from vulnerable populations, including low-income country residents and ancestral knowledge from indigenous peoples.
Practical implications: The dual goal of bringing together physical activity and climate agendas to address human and planetary health must be prioritised urgently, taking a multisectoral collaborative approach focusing on comprehensive and holistic actions through policy change and budget reprioritisations. These changes will require developing policy frameworks, providing financial incentives, mandating sustainable practices, and launching educational and awareness campaigns that prioritise physical activity for the dual goal of protecting the environment and individual health.
Abstract 4: Two-decade progress of national and global physical activity policy
Background: Physical activity policy has the potential to play an important role in conjoining multiple societal sectors to generate supportive environments that increase population physical activity.
Purpose: The purpose of this project was to document trends in the global status of physical activity policy.
Methods: We evaluated global physical activity policy changes from 2004 to 2023 based on policy monitoring from the Global Observatory for Physical Activity (GoPA!) in 217 countries.
Results: The data arranged by GoPA! highlights a notable increase from 2012 (year of the first The Lancet Physical Activity Series) onwards in the prevalence of national physical activity policies over the past two decades. Approximately nine in ten (89.4%) countries now have formal written policies; either a national NCD policy including physical activity or a standalone physical activity policy. A greater number of standalone policies was seen in the European region compared to other World Health Organization ((WHO) regions. Persistent gaps exist in policy and guideline availability in Africa, South-East-Asia, and low-income countries. In virtually all countries evaluation of policy implementation was poor. The majority of policies around the world were time-limited and, without action, will end before or in 2030, the year by which the WHO seeks to reduce global risk factors and wants to achieve a 15% relative reduction in physical inactivity.
Conclusions: Many advances in policy monitoring systems and tools have been made since 2012, but systematic global monitoring for physical activity policy, including implementation and evaluation, has yet to be achieved.
Practical implications: Monitoring global physical activity policies to assess progress in national and global physical activity and NCD prevention policies serves to guide efforts, inform decision-making, and drive actions aimed at fostering healthier populations and mitigating the prevalence of physical inactivity.

The importance of playgrounds for children’s active outdoor play
The importance of playgrounds for children’s active outdoor play
Purpose: The purpose of this symposium is to present an overview of the importance of playgrounds for children’s active outdoor play
Description: Active outdoor play is important for children’s health and development, and playgrounds can provide good places for play. But how do we create good playgrounds in public open spaces, early childhood education and care (ECEC) and schools, that children like to use for active outdoor play? What works, for which type of children, in which context?
In this symposium, four presentations from the United States, Australia and Denmark will shed light on the importance of playgrounds in different settings for children’s active outdoor play. Furthermore, the presentations will include multiple novel methods to measure active outdoor play, and will highlight the importance of engaging children and other stakeholders in the development of new playgrounds.
Together, the presentations will provide valuable information that can help policy makers and city planners prioritize investing in the right playgrounds, for the right context.

Background: ECEC is an important setting to promote preschooler physical activity. The outdoor physical environment has significant potential to influence preschoolers’ physical activity while attending ECEC. Few interventions or studies using device-based measures of children’s physical activity and the ECEC physical environment have been undertaken.
Purpose: Summarize findings from multiple PLAYCE cohort sub-studies investigating the impact of the ECEC outdoor physical environment on young children’s physical activity.
Methods: Wave 1 findings from the ‘Play Spaces and Environments for Children’s Physical Activity’ (PLAYCE) cohort study will be presented and summarised. In wave 1, 1596 preschoolers aged 2–5 years and their parents were recruited from 104 ECEC services across Perth, Western Australia. Physical activity was measured by 7-day accelerometry and GPS. The Environment and Policy Assessment and Observation (EPAO) Instrument and Nearmap aerial imagery captured the ECEC physical environment.
Results: Sandboxes, portable play equipment (balls, slides, floor play equipment) and natural grassed areas were positively associated with preschooler physical activity. The addition of new portable equipment including balls, slides, twirling and floor play equipment resulted in intervention children being more active at follow-up. Spatial data confirmed physical activity hot spots were most common in outdoor open areas and areas with fixed play equipment and natural features.
Conclusions: Fixed and portable play equipment, natural features, and the amount of running space in ECEC outdoor areas and its location in relation to other play areas are important for facilitating physical activity in preschoolers.
Practical implications: Since few preschoolers meet daily energetic play recommendations while at ECEC,
the findings can support ECEC providers to optimize outdoor physical environments and encourage more active play among preschoolers.
Funding: The PLAYCE Study was funded by the Western Australian Health Promotion Foundation (Healthway #32018). HC is supported by an Australian National Heart Foundation Future Leader Fellowship (#102549).

Identifying priorities for improving playground access equity in Austin, Texas, USA: a mixed-methods, community-engaged study
Authors: Deborah Salvo,1 Case Garza,1 Eugen Resendiz1
1 People, Health and Place Lab, Department of Kinesiology and Health Education, The University of Texas at Austin. Austin, Texas, USA
Background: Parks and playgrounds are critical built environment resources for children’s health and development. For many children, playgrounds are the only place for physical activity practice after school, on weekends, and/or during non-school months.
Purpose: To characterize playground access (in)equity in Austin, Texas, USA; and to engage key stakeholders and community members for identifying priorities for playground improvements.
Methods: This study uses a mixed-methods approach. Using GIS, we are mapping all playgrounds in Austin, Texas, and identifying neighbourhoods with high versus low playground availability. We will explore differences in playground access by underlying sociodemographic characteristics of neighbourhoods (income, race/ethnic composition of residents) to diagnose inequities. We are further collecting audit-based and imagery (photography) data in 8 low-income neighbourhoods with high proportions of minoritized residents, to assess the current upkeep/quality of playgrounds in these areas. Additionally, a systematic organizational mapping exercise is underway to identify key people, groups, organizations, and agencies with an interest or influence on playground improvement, renovations, maintenance, and programming. Finally, we are conducting 2-5 key stakeholder/community-member semi-structured interviews with representatives of key sectors (parks and recreation, public safety, environmental protection, placemaking community-based groups), to identify priorities for playground improvements.
Results: Data collection is underway, and will finalize in early May, 2023. Final results will be presented at ISPAH 2024.
Conclusions: Ensuring equity in access to playgrounds is critical for promoting healthy development in children, and for achieving physical activity and health equity.
Practical implications: Using a data-driven approach to identify high need areas, and engaging key stakeholders, including key public sectors are critical approaches for informing the design and implementation of contextually-responsive programs to improve playground access and utilization in high need areas.
Funding: This study was partially funded by the World Playground Research Institute, University of Southern Denmark.

2Center for Clinical Research and Prevention, Frederiksberg Hospital, Frederiksberg, Denmark
Background: School playgrounds are a unique place to promote physical activity for children. However, physical activity on school playgrounds decreases when children get older. Several of our studies have shown that there is a relation between school playground design and physical activity among older schoolchildren.
Purpose: The aim was to compile our evidence and develop recommendations for designing activating school playgrounds for 9-12 year-olds.
Methods: We have compiled our evidence from two school playground studies in Denmark conducted between 2016-2022. In each of the mixed-methods studies, we looked at the relation between physical activity among 9-12-year-olds and school playground design. Using combined accelerometer and GPS data, we identified which type of schoolyard features were used for physical activity. Using go-along interviews, we identified six types of children with different activity preferences. Combining data, we identified which schoolyard features were used by which type of children.
Results: To stimulate active use by 9-12-year-olds, school playgrounds should contain a variety of features such as secluded social areas where they can hang out with each other, areas with age-appropriate physical challenges such as high climbing frames that creates a feeling of risk-taking, sports features such as ball game areas, as well as features for non-competitive activities. Finally, it is important that there is a good balance between paved and natural, vegetated surfaces in the schoolyard.
Conclusions and practical implications: If school playgrounds are designed and built with the right features such as secluded hang-out areas, areas with age-appropriate physically challenging features, as well as sports area, and areas for non-competitive activities, 9-12 years-olds will actively use them, which positively influences their total daily physical activity levels.

Child’s Play: What can we learn from AI-based – clustering algorithms?
Authors: J. Aaron Hipp¹, Jae In Oh1, Morgan Hughey2

2College of Charleston, Charleston, SC, USA
Background: The study of playgrounds has traditionally been via observations, though use of GPS and accelerometers are becoming more frequent. Use of monitoring devices provide more nuanced understanding of use of space, intensity of activities, and where current playspaces may be under-activated.
Purpose: We recruited a diverse sample of youth from playgrounds located in economically-disadvantaged neighborhoods to understand activity intensity on playgrounds, attribute preference, and play clusters within and between playground amenities.
Methods: 5 – 10 year olds wore an accelerometer and GPS during a playground visit. Each playground amenity was mapped with a handheld Trimble GPS. GPS and accelerometer data, with 15 second epochs, were joined using HABITUS software. Clusters of play, or play episodes, were created using the ArcGIS density-based clustering algorithm, OPTICS. Clusters were set with a minimum of five consecutive points (1 minute) and maximum distance of 6m between points. OPTICS output provides clusters of play across an individual’s wear-time allowing for the visualization and description of play across time and space.
Results: The dataset included 40,000 15s epochs of playground use from 321 youth. OPTICS identified 1,727 play episodes. The average playground visit included five three-minute episodes of play. 37% of play episodes occurred on playsets, followed by 8% of episodes on swing sets. 43% of play episodes occurred across or between different play areas within playgrounds (e.g., playing on the slide and then running directly to the swings).
Conclusions: Youth play episodes are varied and often between or beyond provided play equipment. Further research is necessary into the layout and design of equipment that best invites active, creative play and incites return visits.
Practical implications: Understanding play episodes on playgrounds can inform the design of specific playground equipment, layout of diverse amenities across a playground, and help activate under-used spaces.

Real-life assessment of physical activity – Insights from the WEALTH European project
Overall abstract for the symposium
Purpose: The primary purpose of this symposium is to discuss innovative aspects of physical activity measurement provided by work performed in a currently ongoing collaborative European research project (WEALTH).
Description: The symposium will start with an introduction by the Chair (Jean-Michel Oppert, France) on the topic of physical activity monitoring in real-life settings and the needs for improved objective assessment in health surveillance surveys at national and international level. The first presentation (Alan Donnelly, Ireland) will provide an overview of the WEALTH project which main objectives are to develop standardized machine learning (ML) data processing techniques for accelerometer data and to test the feasibility of employing Ecological Momentary Assessment (EMA) to link physical activity and dietary data. The recruitment of participants across four European centers, and the data collection protocol using four accelerometer devices and an Ecological Momentary Assessment (EMA) app during a 9-day monitoring phase will be detailed. The second presentation (Tomas Vetrovsky, Czech Republic) will explain the EMA protocol combining time-based and event-based surveys to label free-living data measurement and assess environmental, social, and psychological contexts of physical and eating behaviors. The third presentation (Christoph Buck, Germany) will detail how ML models are trained and externally validated for prediction of physical and eating behaviors, based on wrist-worn accelerometry. EMA information is then used to refine classifiers of physical behaviors. The fourth presentation (Greet Cardon, Belgium) will focus on the feasibility and acceptability of methods under study and will use an online voting tool to interact with the audience and get the perspective of the researcher/policy maker. The final part of the symposium led by the Discussant (Sebastien Chastin, UK) will strongly involve the audience to get feedback on methods and results from the project and why, when and how they could be used to improve health surveillance surveys.

Title: The WEALTH Project
Background: The WEALTH project (wearable sensor assessment of physical and eating behaviors) is a five-country European partnership focused on the development of improved measurement methods for physical behaviors and their impact on eating behaviors.
Purpose: To develop standardized machine learning data processing techniques for research grade and commercially accessible accelerometer device data, and to test the feasibility of employing Ecological Momentary Assessment (EMA) to link physical activity behaviors and dietary behaviors.
Methods: 600 adult participants were recruited (150 from four European centers) to simultaneously wear four accelerometer devices including two wearables (ActiGraph GTX3, ActivPAL3M, FitBit Charge 5 and Skagen Falster Gen 6) for nine days. Physical and eating behaviors were labelled using feedback from event-triggered and random EMA questions. Anthropometric measures including height, weight and grip-strength were recorded, and participants completed three web-based SACANA 24-hour dietary recall questionnaires. Accelerometer and EMA data were employed to: 1) develop machine learning data-processing techniques to identify activity behaviors, and 2) test the feasibility of using triggered EMA to assess the link between physical and eating behaviors. Participants completed study feasibility questionnaires at the end of the measurement period.
Results: Data collection will be completed by March 2024, and data processing and analysis is currently underway. The large-scale data collection will generate a database which can be interrogated to develop novel methods to explore the relationship between physical and eating behaviors.
Conclusions: The WEALTH project has illustrated the feasibility of employing combined accelerometry and event triggered and random EMA questions to study physical and eating behaviors in large populations.
Practical implications: The WEALTH project methods will be shared at the end of the project and will demonstrate that such methods can be used in national and international surveillance studies.

Title: Ecological Momentary Assessment (EMA): Real-Life Instantaneous Behavior Assessment
Background: Accurate measurements of physical behaviors (PB) and eating behaviors (EB), along with their context, as determined using Ecological Momentary Assessment (EMA), are crucial for understanding the determinants of healthy lifestyles. The WEALTH project aims to develop data processing methods for accelerometer data through a combination of machine learning and EMA.
Purpose: To report on the EMA data collection process undertaken within the WEALTH project.
Methods: The study included a 9-day free-living EMA data collection using the HealthReact system. Participants aged 18-64 years were recruited from four centers (Ireland, Germany, France, Czechia). The EMA protocol combined self-initiated, time-based, and event-based surveys to assess the environmental, social, and psychological contexts of PB and EB. Participants were instructed to self-report EB after each meal, snack, or drink (excluding water). Additionally, they received six time-based surveys daily. Finally, event-based surveys were triggered by near-real-time data from the Fitbit activity tracker following episodes of walking (5min, ≥60 steps/min, max. 4/day), running (5min, ≥140 steps/min, max. 4/day), or prolonged sitting (20min, 0 steps, max. 3/day).
Results: Among the enrolled participants (n=455), an average of 4.4 self-initiated reports of EB per day were recorded. Beyond the six daily time-based surveys, participants were prompted to complete, on average, 4.6 event-based surveys daily, of those x triggered by walking, y by running, and z by prolonged sitting. The response rates for the time-based surveys and those triggered by walking, running, and prolonged sitting were 58%, 65%, 59%, and 66%, respectively.
Conclusions: The collected EMA data will be instrumental in developing and validating machine learning algorithms for detecting PB and EB and their contexts.
Practical implications: The results will be applicable for surveillance and monitoring at the population level, as well as in public health interventions promoting healthy PB and EB.

Presenter 3: CHRISTOPH BUCK, BIPS, Germany
Background: The development of new machine learning (ML) algorithms for behavior classification creates the need for further collection of high-quality data. Based on scripted studies for labeled data assessment, recent ML behavior classifiers show high accuracy mostly in a similar study design, but perform lower based on free-living data.
Purpose: To develop and improve ML models for physical behavior classification considering scripted and free-living labeled data.
Methods: In the WEALTH study, we collected data from 600 participants in four European countries conducting a two-hour scripted study were participants followed a behavior protocol, followed by a nine-day free-living data assessment, where data labelling was supported by ecological momentary assessment (EMA) to identify time stamps of similar behaviors. Classifiers of physical behaviors were modeled based on raw tri-axial accelerometer data from three different sensors, i.e. Actigraph GT3x, ActivPal and 25hz smartwatch data. We used multiple ML methods ranging from random forests as a benchmark model to convolutional neural networks (CNN) as deep learning applications. Based on the scripted study, holdout validation was conducted for model development, and models were further calibrated using free-living sensor data identified by EMA labels.
Results: Our models will be able to classify physical behaviors such as sitting walking, cycling and running, with high accuracy, whereas first results indicate lower specificity for high intensity behaviors due to extensive variation in raw accelerometry data.
Conclusions: Based on EMA labeled free-living sensor data, development of ML models for physical behaviors will show improved
performance for classification from tri-axial sensor data based on free-living study designs.
Practical implications: The developed ML models will allow behavior classification particularly for easy to apply wrist worn wearables, particularly smartwatches, that can be implemented in large surveillance studies.

Presenter 4: GREET CARDON, Ghent University, Belgium
Title: Feasibility and acceptability of technology to provide physical activity and dietary behavior.
Background: Technology to provide real-time, valid physical activity and dietary behavior data holds potential for advanced monitoring and surveillance in adults. The WEALTH project advances the assessment and monitoring of physical and dietary behaviors by maximizing the use of data collected from multiple commonly available measurement devices by standardized data analysis and using a Machine Learning data processing platform and by linking advanced processing of activity data with triggered Ecological Momentary Assessments questioning.
Purpose: We aimed to assess the feasibility and acceptability in study participants and in researchers / policy makers when applying these methods for health behavior assessment.
Methods: As part of the WEALTH project a convenience sample of about 150 participants from 4 countries (Ireland, Germany, France, Czech Republic) filled out a questionnaire (29 questions, 5-point likert scale) after wearing 4 devices (Fitbit, ActivPAL, Skagen, Actigraph) and receiving smart phone based surveys (self-initiated and time based) for 9 days.
Results: Data collection in participants is currently ongoing and will be finalized in February 2024. Results will be presented for e.g.: comfort to wear the devices, ease of handling, comfort of data sharing, ease of responding to smart phone surveys, reactivity on smart phone surveys, technological ease, ease of compliance, privacy issues, general acceptance of the study. Making use of an online voting tool (Mentimeter) in the current presentation the audience will furthermore be asked to rate the feasibility and acceptance of the presented WEALTH methodology to get the perspective of the researcher/policy maker.
Conclusions: Conclusions will be drawn on the feasibility and acceptability of the methodology both from the perspective of study participants as from the researcher/policy maker perspective.
Practical implications: Findings will inform improvements needed in order to harness the potential of technology to provide real-time, valid data for monitoring and surveillance.

The ProPASS consortium: Growth, success, challenges and future directions for an international wearables consortium
Purpose: To explore the development of a leading international consortium of observational studies of physical behaviours, including its challenges, scientific potential, future directions and long-term goals.
Description: The development of international consortia of observational studies of physical behaviours offers unprecedented opportunity to understand links between movement health and disease, and to meet global public health priorities. Since its inception in 2017 the ProPASS (Prospective Studies of Physical Activity, Sedentary Behaviour and Sleep) consortium, has developed at pace to include more 30 large observational studies from 5 continents, and is ideally placed to inform the next generation of physical activity guidelines and promotion.
In this symposium we will share the historical journey and development of ProPASS, its success to date, exciting emergent workstreams and a vision for the future. The symposium will include three presentation sessions, during which delegates will hear from 6 members of the ProPASS leadership group, followed by an interactive panel discussion featuring some of our esteemed international collaborators.
In the first of these talks, Professors Emmanuel Stamatakis (University of Sydney) and Mark Hamer (University College London) will set out the ProPASS mission and its potential future impact, and share valuable insights regarding opportunities and challenges created by ProPASS success and continued growth. Presentation two will focus on key success from the last 12 months. Dr Jo Blodgett (University College London) and Dr Matthew Ahmadi (University of Sydney) will describe the first papers from analyses of the ProPASS pooled data resource which focus on cardiometabolic health and associations with intensity, duration, and type of movement behaviours. In our third presentation, led by Associate Professor Annemarie Koster (Maastricht University) with Dr Jo Blodgett and Dr Matthew Ahmadi, delegates will have the opportunity to hear about new directions and exciting emergent workstreams involving compositional approaches, exploration of device-measured sleep volume and variability, and of physical activity micropatterns.
The symposium will close with an interactive panel discussion where delegates and our expert panel can consider key questions and share ideas on the topic: ‘The present and future of observational physical behaviour research: the role of wearables’.

Abstract 1: Vision and potential impact of the ProPASS consortium: securing the longevity of large international physical activity collaborations
Speakers: Emmanuel Stamatakis, Mark Hamer
Background: The Prospective Physical Activity, Sitting, and Sleep consortium (ProPASS) was launched in 2017 to spearhead the transition to wearables-based evidence for physical activity, sedentary behaviour, and sleep guidelines development. ProPASS currently involves c>100 collaborators and nearly 30 cohort studies. As an international consortium, ProPASS is unique in that it was not set up merely as a data resource, its activities include methodology development, prospective expansion to new cohorts including a formal ISPAH partnership focused on LMICs, and support of Early Career Researchers.
Purpose: To outline the scope, vision, and future potential impact of ProPASS, and share with the ISPAH community the lessons learnt during its development.
Methods: We will first discuss how ProPASS emerged, its vision and the strategy for achieving it, the challenges faced, and its current and likely future impact. The second part of this session will focus on funding strategy and challenges and will highlight the road ahead for the next 4-5 years when the work for the development of the next WHO Guidelines will likely commence.
Results: Despite adverse funding conditions commonly encountered in epidemiological research, ProPASS has grown very fast and is already making an impact in the broader fields of physical behaviour and physical activity. However, its trajectory to date alone is not guarantee of future success. As ProPASS grows so does its breadth of activities and its resource needs. This creates opportunities for more impact but also poses threats on its longevity.
Conclusions: Although ProPASS stands on solid foundations, the next 5 years are critical in determining to what extend ProPASS will fulfil its vision. The support of organisations like ISPAH and its community, will likely be critical for its success.
Practical implications: We will share with the ISPAH Congress insights and lessons learnt from the ProPASS consortium and highlight future directions.
Abstract 2. Key successes from ProPASS consortium: first published papers from six cohorts from our pilot resource
Speakers: Joanna M Blodgett, Matthew Ahmadi
Background: Here we summarise results from the first empirical papers from ProPASS, published in the last year in the European Heart Journal and Diabetologia.
Purpose: We investigated: i) interdependent associations of moderate-vigorous physical activity (MVPA), light intensity PA (LIPA), standing, sedentary behaviour (SB) and sleep with cardiometabolic outcomes; and ii) dose-response associations between activity type (standing, walking, stair climbing, fast walking/running) and cardiometabolic outcomes.
Methods: We pooled data from six cohort studies (n>15,000). Raw accelerometer data was re-processed using the ActiPASS software. For aim i, we conducted compositional logistic regression to explore associations between various compositions of time spent in movement behaviors and six cardiometabolic outcomes, and investigate various behavioural reallocation modelling estimates. For aim ii, we employed generalized linear models with splines to investigate dose-response relationships between activity types and each outcome.
Results: Aim i) More MVPA and less time spent sedentary – relative to sleeping, standing and light activity – was associated with better cardiometabolic outcomes. Less than 10min/day of reallocation of other behaviours into MVPA was associated with significant improvements in outcomes. Aim ii) Accumulating >5 min/day (z-score= -0.14 [-0.24, -0.03] of stair climbing or >64 min/day (-0.14 [-0.25, -0.02] of walking was associated with more favourable composite cardiometabolic health. Every additional minute of stair climbing up to 12 min/day was associated with a similar rate of change as running for the same time interval
Conclusions: Findings on 24-hour movement behaviours may guide more personalised guidance on how an individual can modify their 24-hour movement for cardiometabolic benefits. Findings on cardiometabolic health and durations of different activities of daily living and posture may guide future interventions involving lifestyle modification.
Practical implications: This session will share with the ISPAH Congress audience initial evidence from the ProPASS consortium experience to date and introduce future areas of research.

Abstract 3. New directions and emergent findings from the first ProPASS resource
Annemarie Koster, Joanna M Blodgett, Matthew Ahmadi
Background: The health benefits of moderate to vigorous physical activity and sleep are well-described. Much less is known about the patterns of physical activity and health and in particular the potential health benefits of very short activity bouts in daily living. Further, fewer studies have investigated the full spectrum of daily movement behaviours (including sleep) and assess their interdependencies on health outcomes.
Purpose: In this session we present results from ongoing analysis from the ProPASS consortium on the i) association between activity micropatterns and ii) sleep duration and regularity with cardiometabolic outcomes; iii) compositional individual participant data analyses on sedentary behaviour, sleep, standing, walking (light and fast) and exercise-like behaviours with blood pressure.
Methods: In the first ProPASS recourse we harmonised data from over 15,000 participants across six international cohort studies. Outcomes included body mass index, waist circumference, high-density lipoprotein cholesterol, total cholesterol, triglycerides, HbA1c, systolic blood pressure and diastolic blood pressure.
Results: We will use generalised linear models with splines to examine dose-response associations between micropatternns of physical activity (aim i) and sleep (aim ii) with cardiometabolic outcomes. We will conduct compositional data analysis to examine associations between different compositions of time spent in movement behaviours and each blood pressure outcome, including examining minimal and optimal reallocation of time between behaviours (aim iii).
Conclusions: These studies will provide insight into associations of novel aspects of physical behaviour and health and how reallocating time in one behaviour by another behaviour affects health.
Practical implications: This session shows the scientific value of the first ProPASS resource for novel research on physical behaviour and health.

The 1000 Cities Challenge: Scaling Up the Global Observatory of Healthy and Sustainable Cities
Purpose: To describe the goal and objectives, and science behind the Global Observatory of Healthy and Sustainable Cities; and to encourage ISPAH attendees to join the 1000 Cities Challenge.
Description: The Global Observatory of Healthy and Sustainable Cities (GOHSC) provides comparable, evidence-based spatial and policy indicators of healthy and sustainable urban design and planning for cities internationally to diagnose the extent to which their current status is promotive of health and sustainability, identify areas of improvement, set goals, and benchmark progress. Dr. Deborah Salvo, Co-Director of GOHSC, will chair this Symposium, and will open the session by providing an of the GOHSC and 1000 Cities Challenge Project – an initiative to upscale the GOHSC to include data and partners from over 1000 cities worldwide. This brief introduction will be followed by four 12-to-15-minute presentations. Presentations 1 and 2, by Dr. Melanie Lowe (Co-Director of the GOHSC and lead of the policy indicators team) and Dr. Geoff Boeing (spatial indicators team member, currently led by Carl Higgs), will describe the rationale and evidence behind the policy and spatial indicators included in the GOHSC, and the open access tools available for new members to join the 1000 Cities Challenge. Presentations 3 and 4, by Dr. Anna Puig-Ribera and Dr. César Hernández, will reflect on the lessons learned by two GOHSC members, who are applying spatial and policy indicators to multiple cities in their respective countries, Spain and Mexico. Dr. Jim Sallis, member of the Executive of GOHSC, will serve as a discussant. There will be about 20 minutes for facilitated discussion on opportunities to participate in the 1000 Cities Challenge at the end of the session.

Background: City planning policies influence health and sustainability by impacting urban lifestyles and exposure to health and environmental risks. Internationally relevant, evidence-informed urban policy indicators are useful for assessing and comparing whether cities have the policy frameworks in place to deliver healthy cities, and for monitoring progress over time.
Methods: For a 2022 Lancet Global Health series, we developed policy indicators to assess the presence and quality of policies associated with health and sustainability for 25 cities internationally. To upscale this study, our indicators are now available open access via our 1000 Cities Challenge, as part of the Global Observatory of Healthy and Sustainable Cities. Through expert consultation and literature review we developed a comprehensive policy indicator checklist tool for the 1000 Cities Challenge, which includes additional measures of sustainable and resilient land use and transport.
Results: Researchers, policymakers and advocates in cities worldwide are using our open access policy indicator checklist to assess policies for their city, and generate city scorecards and reports. The policy indicators can be applied to any jurisdiction, from whole metropolitan regions to smaller urban areas. The 1000 Cities Challenge indicator reports show policy gaps and limitations and highlight opportunities to strengthen policy frameworks for each city. The indicators also enable comparisons of policies between different cities.
Conclusions: We invite scholars, policymakers, practitioners, students and advocates to join the 1000 Cities Challenge, use our open access tools and become part of our global collaboration.
Practical Implications: This presentation will outline practical steps and benefits of applying the 1000 Cities Challenge’s policy indicators. The indicators and city reports generated can be used to inform local advocacy, and support urban policy and practice innovations towards healthy and sustainable cities.

Background: Cities’ built environments shape human mobility, physical activity, sustainability, and planetary health. Creating healthier and more sustainable cities is a global priority integral to achieving sustainable development goals and health equity goals. Spatial indicators of relevant urban design and transport features can help planners target interventions and compare both between cities (benchmarking) and over time (monitoring) to measure progress toward these critical goals. However, most urban indicator frameworks use coarse spatial scales that only allow between-city comparisons or require expensive, technical, local spatial analyses for within-city comparisons.
Methods: We report our recent advances in using open data and open source tools worldwide, in conjunction with local collaborators, to model and measure urban design and transport features that support active travel behavior. We developed a reusable open-source urban indicator computational framework using open data to enable consistent local and global comparative analyses for the 1000 Cities Challenge.
Results: Our analytics can unlock new measures of health and sustainability around the world. Our pilot demonstration—for 25 diverse cities in 19 countries—produced these spatial indicators of urban design and transport features in conjunction with local collaborators for data gathering and validation. We also identified populations living above and below critical thresholds for physical activity through walking. The 1000 Cities Challenge reports then link these spatial outcomes to cities’ policy contexts to understand implementation gaps and support local advocacy.
Conclusions: These analytics can be run anywhere in the world to calculate local indicators of the built environment’s ability to support healthy and sustainable lifestyles.
Practical Implications: We present the software framework to run these analytics and invite collaborators to join us in the 1000 Cities Challenge to support evidence-informed planning for healthier and more sustainable cities.

Using evidence-based urban indicators and open science to promote active and sustainable cities in Spain
Anna Puig-Ribera, Xavier Delclòs-Alió, Marc Domínguez-Mallafré, Ana Queralt, Javier Molina-García.
Background: Implementing urban policies to enhance accessibility, sustainability and active mobility is a key issue for promoting urban health. To maximise the effectiveness of urban policies on the achievement of environmental, social, and health-related benefits, there is a need for high quality evidence-based data to guide and inform policymakers on the design, implementation, and evaluation of urban interventions. We examined to what extent several cities in Spain present sustainable and healthy urban designs and policies.
Methods: The Global Healthy and Sustainable City Indicators (GHSCI) Software (1) calculated a set of spatial indicators relative to accessibility and urban design in the ten largest Spanish cities, (2) initiated the implementation of the policy checklist for these cities and, (3) piloted the impact of several urban actions from a Local Urban Master Plan in a medium-sized city.
Results: The spatial indicators showed that most residents (64-84%) in large Spanish cities live in highly accessible and walkable neighbourhoods, while the software implementation also raised methodological challenges. The new version of policy indicators analysis provided a detailed analysis of a wide range of indicators to be evaluated despite a greater investment of time was required. Moreover, the importance of having a local collaborator to help validate the policy results was noted.
Conclusions: The open data and software framework developed for the 1000-city challenge allows for highly detailed spatial indicators. The experience of applying the new version of indicators has been successful. Spatial and policy indicators can be applied in large-scale and comparable analyses of healthy and active cities.
Practical Implications: Spatial and policy indicators and evaluation can be highly useful for local and regional planners to understand not only the spatial distribution of infrastructure and services that promote health but also to their effectiveness and identify possible inequalities between and within cities.

Engaging local decision makers to join the 1000 Cities Challenge in Mexico.
César Hernández-Alcaraz, Eugen Resendiz, Alejandra Jáuregui, Deborah Salvo
Background: In addition to measuring what matters, it is imperative to engage with local stakeholders, including government and non-government organizations (NGO), to support evidence-based decision making and benchmarking in cities (i.e., using evidence for action). Recently, funding was secured for Mexico to join the 1000 Cities Challenge, scaling the application of the indicators of the Global Observatory of Healthy and Sustainable Cities (GOHSC) to 10 cities, and building partnerships with local decision makers to enable evidence-based urban policy and planning in Mexico.
Purpose: To describe the process of engaging local decision-making agencies in Mexico, for enhancing the reach and impact of the 1000 Cities Challenge.
Methods: Ten cities of varying sizes and economic development levels were selected (Mexico City, Guadalajara, Monterrey, Merida, Toluca, Tijuana, Leon, Cuernavaca, Colima-Villa de Alvarez, and Tapachula) joining the 1000 Cities Challenge. A local (Mexican) GOHSC Executive Committee has been established, charged with designing a consultation process to identify and engage governmental and non-governmental agencies and actors.
Results: A variety of engagement strategies have been implemented, including initial email contacts and direct messages on social media, and key NGO partners have been identified, which in turn are facilitating connections with local government agencies. A GOHSC/1000 Cities Challenge workshop for engaging local government representatives is being planned for 2024.
Conclusions: Building equitable partnerships with NGOs and other decision-making agencies involved in the urban policy and planning realms is an effective strategy for optimizing the scale up and impact of GOHSC in countries like Mexico.
Practical implications: The process of identifying and engaging local decision makers for supporting GOHSC activities may be context-specific. Adaptations to this process is recommended across countries and regions, based on the local policy making landscape, to maximize the impact of data for promoting healthier and more sustainable cities worldwide.
