Bridging BIM and LCSA to Greening Existing Buildings: From A Literature Review to Development of Conceptual Framework
Authors: Zulkefli N S , Mohd Rahim F A , Zainon N
Published: August 2022

Instead of looking into new building, this study shifted the focus to existing buildings considering the area has been less explored although the amount of energy released during the phase has significant influence towards sustainability impacts. Deriving from the situation, the purpose of this paper is to explore the potential of bridging BIM and the four-steps approach of Life Cycle Sustainability Assessment (LCSA) as an assisting tool to improve the performances of existing non-green buildings. To achieve aforementioned aim, an extensive literature review to identify the nexus between the two areas is done, as well as possibilities and challenges surfaced pertaining to the idea. Literature review process consists of several approaches including literature searching, classifying, and analysis were conducted. Based on literature review, a research gap is identified, and an initial conceptual framework is developed. The framework entails several areas of research that highlight on integrating LCSA approach, sustainability indicators and BIM functions. Apart from that, several implementation considerations to integrate both areas have been identified too. The conceptual framework presented in this study will serve as a basis to further develop an implementation framework that integrates BIM and LCSA to greening existing buildings. The final implementation framework is expected to assist project stakeholders including project manager (or facility manager), building owner, and consultants in making decision towards improving existing buildings’ sustainable performance.
Turbidity reduction in palm oil mill effluent (POME) by submerged fermentation with immobilized Aspergillus niger spores using coconut husk
Authors: Thegarathah Paveethra , Jewaratnam Jegalakshimi , Simarani Khanom
Published: August 2022

Increasing production of palm oil in Malaysia has been releasing an alarming rate of palm oil mill effluent (POME). POME must be treated prior to release into the environment. Turbidity reduction by fermentation in palm oil mill effluent (POME) reduces the chemical oxygen demand (COD) which improves the effectiveness of downstream treatment. Aspergillus niger is a promising decomposer but as a filamentous fungus, its performance could be enhanced when it is supported with fibrous surface to provide a larger surface area for growth. Waste material from agroindustry constituted from lignocellulose have been widely used in the immobilization process to reduce costs. In the present study, sterile coconut husk was used to immobilize A.niger cells. POME, the fermentation media was prepared at concentrations ranging from 0-100%. Post fermentation slurry was filtered. Turbidity for every concentration were recorded. A free cell fermentation was conducted for comparison. The immobilized cell fermentation shows turbidity reduction between 95% and 98% while the free cell fermentation shows reduction between 87% and 95%. The immobilized cell produced a better turbidity reduction percentage.

Published: August 2022

High costs associated with chemical triggers to promote microalgae productivity when waste-based sources are used as nutrients source has diverted the attention of microalgae growers to seek for sustainable substitute for synthetic triggers. On the other note, vast disposal of chicken feather waste cause severe environmental pollution due to its low decomposition characteristics. Following the call for rigid regulations on its disposal and in attempt to valorize this waste, chicken feathers were subjected to hydrolysis process using 1M sodium hydroxide (NaOH) and precipitated by 1M hydrochloric acid (HCL) to produce chicken feather protein hydrolysate (CFPH). The prepared CFPH was further tested for its feasibility as biostimulant for Chlorella vulgaris grown in organic fertilizer as nutrients source. From the data obtained via elemental analysis, the protein content of CFPH was determined as 73.56%. The biomass and lipid productivities of C. vulgaris cultures were significantly improved by 30.4 and 34.3 to 44.6%, respectively compared to control cultures. This research work indicated that CFPH may serve as a potential low-cost biostimulant for simultaneous augmentation of microalgae biomass and lipid. Characterization of physicochemical properties of the produced CFPH is an essential step in identifying possible avenues for its application in microalgae cultivation.

Published: August 2022

Surface texturing has been widely used to improve the performance of bearings. To further investigate the effect of surface morphology on rigid bore aerodynamic journal bearings and to improve the performance of bearings, this paper investigates the effect of surface roughness and surface texture on the static characteristics of radial rigid bore aerodynamic journal bearings using numerical analysis. The compressible Reynolds lubrication equation of the rigid bore aerodynamic journal bearing is solved by Successive Over Relaxation (SOR) and finite difference method. The static performance of the bearings with different parameters was investigated. The parameters that have been studied include the shape of the texture, the depth of the texture, the number of textures, the percentage of textures, and the surface roughness. The results show that radial rigid bore aerodynamic journal bearings with specific parameter textures have 36.32% higher load carrying capacity and 1.66% lower frictional torque compared to the case without texture.

Two-point correlation function and its applications to the Schrödinger-Lohe type models
Authors: Ha Seung-Yeal , Hwang Gyuyoung , Kim Dohyun
Published: August 2022

We study the asymptotic emergent dynamics and the continuum limit for the Schrödinger-Lohe (SL) model and semi-discrete SL model. For the SL model, emergent dynamics has been mostly studied for systems with identical potentials in literature. In this paper, we further extend emergent dynamics and stability estimate for the SL model with nonidentical potentials. To achieve this, we use two-point correlation functions defined as an inner product between wave functions. For the semi-discrete SL model, we provide a global unique solvability and a sufficient framework for the smooth transition from the semi-discrete SL model to the SL model in any finite-time interval, as the mesh size tends to zero. Our convergence estimate depends on the uniform-in-

SADeepcry: a deep learning framework for protein crystallization propensity prediction using self-attention and auto-encoder networks
Authors: Wang Shaokai , Zhao Haochen
Published: August 2022

The X-ray diffraction (XRD) technique based on crystallography is the main experimental method to analyze the three-dimensional structure of proteins. The production process of protein crystals on which the XRD technique relies has undergone multiple experimental steps, which requires a lot of manpower and material resources. In addition, studies have shown that not all proteins can form crystals under experimental conditions, and the success rate of the final crystallization of proteins is only <10%. Although some protein crystallization predictors have been developed, not many tools capable of predicting multi-stage protein crystallization propensity are available and the accuracy of these tools is not satisfactory. In this paper, we propose a novel deep learning framework, named SADeepcry, for predicting protein crystallization propensity. The framework can be used to estimate the three steps (protein material production, purification and crystallization) in protein crystallization experiments and the success rate of the final protein crystallization. SADeepcry uses the optimized self-attention and auto-encoder modules to extract sequence, structure and physicochemical features from the proteins. Compared with other state-of-the-art protein crystallization propensity prediction models, SADeepcry can obtain more complex global spatial long-distance dependence of protein sequence information. Our computational results show that SADeepcry has increased Matthews correlation coefficient and area under the curve, by 100.3% and 13.4%, respectively, over the DCFCrystal method on the benchmark dataset. The codes of SADeepcry are available at https://github.com/zhc940702/SADeepcry.

Published: August 2022

Background

To provide useful insights into measles elimination progress in China, measles surveillance data were reviewed, and the transmission patterns of measles viruses circulating in China during 1993–2021 were analyzed.

Methods

Measles incidence data from the National Notifiable Disease Reporting System of the China Center for Disease Control and Prevention were analyzed. A total of 17 570 strains were obtained from 30 of 31 provinces in mainland China during 1993–2021. The recommended genotyping window was amplified. Genotyping analysis was conducted for comparison with the reference strains. Phylogenetic analyses were performed to identify genetic relationships among different lineages within the genotypes.

Results

With high coverage of routine immunization and intensive supplementary immunization activities, measles incidence has shown a downward trend since 1993, despite 2 resurgences, reaching a historic low level in 2020–2021 (average 0.5 per million). During 1993–2021, 9 genotypes including domestic genotype H1; imported genotypes B3, D4, D8, D9, D11, G3, and H2; and vaccine-associated genotype A were identified. Among them, the genotype H1 strain circulated endemically in China for more than 25 years; the last strain was detected in Yunnan Province in September 2019. Multiple imported genotypes have been identified since 2009 showing different transmission patterns. Since April 2020, no imported strains have been detected, while vaccine-associated genotype A continues to be detected.

Conclusions

The evidence of low incidence during 2020–2021 and virological surveillance data in this study confirm that China is currently approaching measles elimination.
Economic evaluation of physical activity interventions for type 2 diabetes management: a systematic review
Authors: Barbosa Ana , Whiting Stephen , Ding Ding , Brito João , Mendes Romeu
Published: August 2022

Background

Economic evaluation of physical activity interventions has become an important area for policymaking considering the high costs attributable to physical inactivity. However, the evidence for such interventions targeting type 2 diabetes control is scarce. Therefore, the present study aimed to synthesize economic evaluation studies of physical activity interventions for type 2 diabetes management.

Methods

A systematic review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 statement (PROSPERO reference number CRD42021231021). An electronic search was performed in PubMed, Web of Science, Cochrane Library and NHS Economic Evaluation Database. Studies were eligible if they included: adults with type 2 diabetes; any physical activity intervention in the community settings; an experimental or quasi-experimental design; and a parameter of economic evaluation [cost analysis of interventions, cost-effectiveness analysis (including cost-utility analysis) and cost-benefit analysis] as an outcome.

Results

Ten studies were included in this review: seven were randomized controlled trials and three were quasi-experimental studies. All studies included direct costs, and four also included indirect costs. Four studies demonstrated that physical activity interventions were cost-saving, six studies showed cost-effectiveness, and two studies reported cost-utility. The estimates varied considerably across the studies with different analytical and methodological approaches.

Conclusion

Overall, this systematic review found that physical activity interventions are a worth investment for type 2 diabetes management. However, comparability across interventions was limited due to heterogeneity in interventions type, design and delivery, which may explain the differences in the economic measures.
Differences in body composition and physical fitness parameters among prepubertal and pubertal children engaged in extracurricular sports: the active health study
Authors: Manzano-Carrasco Samuel , Garcia-Unanue Jorge , Lopez-Fernandez Jorge , Hernandez-Martin Antonio , Sanchez-Sanchez Javier , Gallardo Leonor , Felipe Jose Luis
Published: August 2022

Background

This study aimed to analyze the associations of maturity status, chronological age and sex with physical fitness and body composition among active children.

Methods

A total of 1682 children (72% boys; age = 11.22 ± 2.64 years; height = 147.57 ± 15.87 cm; weight = 44.55 ± 15.29 kg) from rural areas participating in extracurricular sports were divided into four groups according to their sex and maturity status (prepubertal and pubertal according to stages described by Tanner). Body composition (body mass index, muscle mass and fat mass) and physical fitness (20-m shuttle-run test, handgrip strength and vertical jump) were assessed using standardized procedures. A two-way ANOVA and product–moment correlations were performed.

Results

Prepubertal boys had more fat mass (%) than pubertal boys [P<0.001; effect size (ES): 0.45], while prepubertal girls had more muscle mass (%) than pubertal girls (P<0.001; ES: 0.47). The pubertal group displayed higher fitness outcomes (absolute values) regardless of sex (P<0.05). However, the prepubertal group had higher percentile values in the 20-m shuttle-run test and vertical jumps than the pubertal group regardless of sex (P < 0.001; ES: 0.29–0.48). All the measures of physical fitness were positively associated with chronological age and muscle mass (%).

Conclusions

Although absolute values of body composition and physical fitness appear to increase among pubertal children participating in extracurricular sports, the percentiles indicate that puberty is accompanied with a loss of a physical fitness levels. Thus, extracurricular sports might not be enough to enhance fitness among adolescents.

Published: August 2022

Background

The aerobic part of the recently updated physical activity (PA) guidelines for adults recommends at least 150 min of moderate or at least 75 of vigorous-intensity PA or an equivalent combination of both. PA can be accumulated of any bout duration. On an absolute scale, moderate-intensity threshold is 3 metabolic equivalents (METs) and vigorous 6 METs. On a scale relative to individual’s personal capacity, moderate-intensity threshold is 40% and vigorous 60% of the oxygen uptake reserve. In this study, the adherence to the new guidelines was evaluated using both absolute and relative thresholds.

Methods

Totally, 1645 adults aged 20–64 years, participated in this population-based study and their cardiorespiratory fitness (CRF) was estimated with 6-min walking test. The participants with estimated maximal oxygen uptake <7.9 MET were categorized as low CRF group and the others as adequate CRF group. The participants were instructed to wear a triaxial hip-worn accelerometer for 1 week and their adherence to PA guidelines was assessed from the accelerometer data.

Results

The adequate CRF group had higher adherence to PA guidelines with the absolute thresholds, but the use of relative thresholds inverted the results. The adherence varied from 20% to 99% in the total sample depending on the analysis parameters of accelerometer data.

Conclusions

The absolute thresholds provide a more appropriate basis to assess the adherence to PA guidelines in population-based samples and interventions. The use of individually determined relative thresholds may be more useful for individual exercise prescriptions in PA counseling.
S03 A physical literacy eco-system in Denmark: from research to practice … and back again
Authors: Elsborg Peter , Bentsen Peter , Nielsen Glen , Melby Paulina Sander , Ryom Knud , Kurtzhals Mette
Published: August 2022

The burden of non communicable diseases is a rising global problem and the increasing inactivity seen all over the world is extremely costly to societies (Ding et al., 2016). A recent Danish evaluation on physical activity (PA) showed that a considerable number of Danish children and adolescents do not meet national PA recommendations (The Ministry of Health, 2019). Viewing this problem through a life course perspective points to the solution of making sustainable behavioural changes with children (Frohlich & Potvin, 2010). Across the life span, there is clear evidence of the health-enhancing benefits of PA (Lee et al., 2012). However, at the same time, ample empirical evidence supports that extrinsic motives for participating in PA, such as increasing health, are insufficient when long term participation is the goal. This means that prevention and health promotion interventions should not blindly target the factors and behaviours that predict adult health, such as PA, but move towards intervening on the ‘so-called’ causes of the causes such as factors enabling a physical active lifestyle throughout life. Physical literacy (PL) is a comprehensive multidimensional concept that has been identified as a ‘cause of the causes’. PL consists of dimensions that lay the foundation for an individual’s capacity and tendency for engaging in physical activities throughout life (Whitehead, 2001). In this symposium, we aim to present four research and interventions projects from the education, sport and public health sectors that have emerged in the last couple of years, and through the presentation of these projects, how we in Denmark have established a PL ecosystem between research and practice – and how our national collaboration, PL-net, has contributed to this.

Authors: Ryom Knud , Kirkegaard Helene , Østergaard Jane Nautrup , Maindal Helle Terkildsen
Published: August 2022

Background

Children’s health is generally considered a complex interplay between multiple factors. Interventions building on community-based participatory research and system dynamics have shown promising potential in improving children's health behavior and well-being. This presentation aims to present how physical literacy can be used to guide and evaluate a systemic approach to health promotion.

Methods

System dynamics techniques such as group model building, is used to engage a whole community in a rural area of Denmark and develop local actions for enhancing among other physical activity. A central health outcome in The Child-COOP Denmark study is physical literacy, which is measured by using DAPL (the Danish version of CAPL). Physical literacy will be used as a central element to guide and evaluate the project. The evaluation design includes repeated measures of childhood health behavior, physical literacy and well-being among 100 children (6-13 y) attending the local primary school. With data collection at baseline and at 2 and 4 years of follow up.

Results

Furthermore, physical literacy results throughout the project period will also be used to guide new local actions in the environment aiming to enhance the local children’s health, well-being and physical activity.

Discussion

The potential of using physical literacy measures to guide and evaluate a participatory systems approach in order to solve complex health problems, is discussed and debated with the audience.
S09-1 Which transport policies increase physical activity of the whole of society? A Systematic Review

Published: August 2022

Background

There is strong evidence of the links between car-dependence and the global physical inactivity epidemic. If eliminated, physical inactivity would remove between 6% and 10% of major non-communicable diseases that are the leading cause of death globally, killing 38 million people each year. Research consistently shows that unlike passive transport (e.g. driving a car), active transport (i.e., walking, cycling) is associated with higher total daily physical activity (PA). While there are public policies that support PA in transport and, as a result, overall PA levels, the specific quantitative effect of such policies on PA behaviour has not been sufficiently investigated. The aim of this systematic review is to determine the level and type of evidence for policies in the area of transport that contribute to higher PA levels of society at large.

Methods

Six databases (MEDLINE (Ebsco), SportDiscus, Cinahl, Cochrane library, Web of Science, and Scopus) were searched for key concepts of policy, transport, evaluation and PA. Methodological quality was assessed using standardised tools. The strength of the evidence of policy impact was described based on pre-determined categories of positive, negative, inconclusive or untested.

Results

17 of 2,549 studies were included in the data synthesis. The authors identified three main transport policy areas with 60 individual policy actions that had a direct or indirect effect on PA. The policy areas were: convenient transport infrastructure development, active travel promotion and shift of transport mode. These areas correspond to Haddon's methodological approach of the transport system division in to three elements (human, vehicle, road). More than half of the policy actions identified (53%) had a positive effect on PA. Study quality ratings were moderate to good.

Conclusions

PA levels can be increased by implementing policies that provide convenient, safe, and connected walking and cycling infrastructures, promote active travel and give strong support to public transport. There is also clear evidence that active travel policies work best when implemented in a comprehensive way (very often as a combination of several policies). This may include infrastructure and facility improvements as well as educational programmes to achieve substantial shifts towards active modes of travel.
P01-14 National policy response to the Sustainable Development Goals: a physical activity case study of Wales
Authors: Sharp Catherine , Mackintosh Kelly , Willmot Rhi , Hughes Rachel , McNarry Melitta , Milton Karen
Published: August 2022

Issue

Population level changes in physical activity (PA) may benefit from policy intervention. In response to the UN Sustainable Development Goals, Wales introduced legislation (the Well-being of Future Generations (Wales) Act 2015) to holistically improve health and well-being, including the translation of national policy into practice. This audit provides a case study approach that could be replicated by researchers in other countries to appraise the role of PA actions in national and sub-national policies.

Description

An audit of policies published by national and sub-national public bodies between 2015 and 2020 was conducted. The list of identified policies was reviewed by an external panel to act as a ?critical friend? to verify its inclusiveness. Content of the policies were extracted and synthesised to determine: (i) how many policies included a PA action; (ii) what the drivers of those policies were; (iii) the content of the PA actions; and (iv) how the PA actions aligned with the Well-being of Future Generations (Wales) Act 2015.

Results

A final list of 73 policies was obtained. Only 16 national-level documents had a PA action, which had been published by 4/13 public bodies (who are bound by the Act). Of the 19 sub-national well-being policies, 15 included PA actions. Most policies were considered reactive and varied in terms of the clarity and specificity of the actions, the assignment roles/responsibilities, and the setting of targets; all overarching principles which can be used to strengthen national and sub-national policy in the future. The most common theme of action across the national-level documents was the broad action of PA promotion, which was identified in nine of the 16 documents. The actions within the national-level documents were reflected in the sub-national well-being plans.

Lessons

This research used a novel approach to assess alignment of policies related to PA and the Sustainable Development Goals (SDGs) in Wales. It provides an overview of the current status of policy related to PA in Wales, which can be used in manifestos and frameworks to shape the subsequent actions of public bodies.

Main messages

This case study provides a valuable example of how to utilise PA to address broader health and wellbeing agendas, and specifically the SDGs. It also demonstrates an approach to achieving stronger connections between national and sub-national policy to support the translation of policies into practice.
P02-06 Citizen science during Covid-19 pandemic to enhance an activating environment in a low-SES neighborhood
Authors: Van Holland Berry , Jepkema Nikki , De Jong Johan
Published: August 2022

It is widely known that people from a low-SES background show a less healthy and active lifestyle. One neighborhood in Groningen, the Netherlands, is a neighborhood housing about 12,000 citizens with on average a low-SES background. In the past, initiatives have been undertaken to promote an active lifestyle by implementing outdoor facilities stimulating physical activity. However, use of these facilities was poor due to lack of citizen involvement. Aim of this project was to engage citizens in the overall process of capturing, plan making and prototyping of concepts for an exercise-friendly physical and social environment.

In the period from January-November 2020 a Living Lab was set up following the “Our Voice” citizen science method. Participatory citizen science was applied in which a community of stakeholders (public and private parties) and citizens was set up. This composes the first step of design thinking: empathizing. The community addressed the aforementioned problem by creating more insight in promoting or degrading features in the neighborhood concerning an active lifestyle (design thinking step 2: defining). For this, citizens made use of the Stanford Neighborhood Discovery Tool. Due to local COVID-19 restrictions, citizens did not collect data individually but were accompanied by a researcher during research walks. The Tool allowed for systematic observations of the physical environment. Additionally, the emergent research walks gave additional information on neighborhood barriers and facilitators next to Discovery Tool data.

Use of the Discovery Tool created an overview of the neighborhood. Based on positive and negative features, new ideas were generated for improving exercise-friendliness (design thinking steps 3 and 4: ideating and prototyping). Furthermore, a work group of citizens was formed which discussed their prototypes with the local government and will be involved in carrying out the ideas.

Our project resulted in a citizen science approach which can be transferred to other neighborhoods. Use of the Discovery Tool showed many benefits for plan making for the neighborhood. Early and continuous involvement of citizens will lead to more sustainable engagement and is a powerful method to create engagement around societal problems and social innovation in the field of Health Enhancing Physical Activity.

Published: August 2022

Background

A widespread dissemination of effective evidence-based physical activity (PA) interventions is needed whether a greater proportion of the population, who could potentially benefit from it, wants to be reached (Finch et al., 2016). ‘Sigue la Huella' (Follow the Footprint), is one of the few effective evidence-informed PA school-based interventions conducted on adolescents in Europe, with the support of the family and the community (Murillo et al., 2014). The main aim of this study is to describe and analyze the process of dissemination of this intervention program.

Methods

The ‘Sigue la Huella' was implemented at one secondary school situated in Jaca/Huesca (Spain). The Replicating Effective Programs (REP) framework was used, because provides a roadmap for disseminating effective interventions (Kilbourne et al., 2007). The intervention was delivered through workshops, ongoing technical assistance to the teachers, and the distribution of an instructional guide among the teachers and the school staff. A quasi-experimental design was adopted to examine the effect of ‘Sigue la Huella' after its dissemination process. PA was assessed using accelerometers at baseline and after the intervention of 14 weeks. In addition, we evaluated the dissemination process using the PRACTIS guide (Koorts et al., 2018).

Results

From an initial evaluation of the dissemination process, several key learnings emerged:

Conclusions

This study provides a comprehensive overview of the dissemination process of an effective school-based program identifying contextual barriers and facilitators that influence program implementation in new contexts and the direction of specific strategies to address those barriers.
P02-10 Irish primary school teacher's perceptions and practices of physical education provision
Authors: Teehan Mairéad , Kelly Lisa , Lane Aoife , Cheilleachair Niamh Ní , Dowd Kieran
Published: August 2022

Background

Primary school physical education (PE) is critical for the development of skills that are essential for lifelong participation in physical activity (PA). Despite this, PE provision in Irish schools is inconsistent, while just 17% of Irish children currently achieve the recommended 60 minutes of daily PA. PE exposes children to regular, developmentally appropriate PA and teachers are essential in ensuring high quality PE is provided. This study aims to examine the perceptions and practises related to PE amongst Irish primary school teachers.

Methods

A survey was developed and validated using a modified Delphi technique and included 57 questions to examine Irish primary school teachers current teaching practices and supports needed to enhance their PE provision. A link to the survey was emailed to all Irish primary schools and shared on social media. SPSS version 27 was used for data analysis.

Results

Of the 473 respondents, 84.4% were female, 15.2% male and 0.4% didn't say (median age=34 (IQR=12)). Respondents indicated PE is timetabled (90.7%) and taught weekly (97%) in most schools. Time allocated for PE is used for other subjects in 35.9% of cases. Respectively, 40.8% and 52.4% of respondents indicated they never plan for or reflect on their teaching of PE. Just 57.1% of respondents indicated sufficient facilities, while 46.3% believe their equipment is insufficient. Approximately half (45.5%) have undertaken continuous professional development, citing a lack of courses offered, time and other priorities as barriers to undertaking additional training. Teachers cited their own lack of competence and confidence to teach PE as reasons why they would welcome engagement from a specialist PE teacher for certain strands (32.3%) or as a general support in PE (24.1%).

Conclusion

Although the vast majority of primary school teachers deliver PE on a weekly basis, these findings suggest teachers require additional supports to assist in their provision of PE. Novel approaches, such as the engagement of specialist PE teachers to support delivery in primary schools, are required to improve PE for Irish youths.
P03-01 The effect of device-free recess on schoolchildren's physical activity and social interaction
Authors: Pawlowski Charlotte Skau , Knudsen Louise Stjerne , Nielsen Jonas Vesterggard , Schmidt Tanja
Published: August 2022

Background

In Denmark, 74% of the 11-15-years-old children do not reach national recommendations on physical activity and 6% (∼20.000 children), experience unwanted loneliness. School recess provides a unique opportunity for children to be active with others and form good relations. However, studies have found that many children perceive electronic devices such as mobile phones, tablets and computers as a key barrier for engaging in active play with other children during recess. These findings are based on perceptions from qualitative data. To our knowledge, no studies have investigated the effect of device-free recess on children's recess behaviour. This knowledge is asked for by school boards, health professionals and politicians to inform future policies and actions. Therefore, the aim of this intervention study is to investigate the effect of device-free recess on schoolchildren's physical activity and social interaction.

Methods

During April-June 2020 device-free recess environments will be implemented at seven Danish schools. Children will be asked to place their mobile phones, tablets and computers in locked? device-hotels? during recess for a four-weeks intervention period. Among a cohort of 900 children from Grades 4-6 (10-13 yrs.) physical activity and social interaction during recess will be measured before and during the last intervention week using questionnaire and systematic observation (SOPLAY). All data will be analysedusing multilevel modelling for repeated measures to see pre- versus post intervention changes.

Results

Since the data collection will be carried out in spring 2020, results cannot be presented yet. However, the results will be ready for the HEPA conference in September 2020. Our hypothesis is that the children will increase their physical activity level and social interaction. However, we will also look into recess behaviourpre- and post-intervention across different subgroups of children e.g., gender, age, screen and physical activity habits prior intervention.

Conclusions

The study will be a crucial contribution to the limited knowledge in this field, and in line with the strategy of HEPA, the ambition is to provide evidence-based knowledge on which to base future decisions to improve the everyday conditions for schoolchildren's physical, social and mental development and health.

Authors: Gallardo Rodrigo , Léniz Laura , Gallardo Karen , Gallardo Orlando
Published: August 2022

Background

Physical activity promotes the better physical and emotional well-being of children. A high percentage of Chilean children do not reach the minimum daily time expected of physical activity. Parents and educators of preschoolers are fundamental to the development of activities that involve movement. This study aimed to examine the relationship between the weekly time that Chilean preschoolers include physical activity in their plays and children's development. Also, compare child development between preschoolers who engaged in physical activity play with or without caregivers' presence.

Methods

The sample consisted of 54 preschoolers aged 34.7-65.9 months (mean 52.0±10.2). The parents completed: a) Ages and Stages Questionnaire Third Edition to measure communication, motor, solving-problem, and personal-social development, and Ages and Stages Questionnaire Socioemotional to measure the socio-emotional development of children and their areas (self-regulation, compliance, autonomy, adaptive functioning (physiological needs), affection, social communication, and interaction; b) an ad-hoc questionnaire to register the time that children dedicate weekly to physical activity on their play, and if their children engaged in play that included physical activity with their caregivers or not.

Results

Pearson coefficient showed that preschoolers' time spent weekly on plays that included physical activity was moderate and significant (p > 0.05) when related to social communication's, adaptive-functioning's, personal-social's, and communication's development. T Student for independent samples revealed that Self-regulation (t=-2.09; p > 0.05) and adaptive-functioning's development (t=-2.99; p > 0.01) were better in preschoolers engaged in play that included physical activity with their caregivers than those who did not play with them. A multivariate regression analysis indicated that preschoolers' adaptive-functioning could be predicted by a combination of higher time dedicated weekly to physical activity on their play and children playing with their caregivers.

Conclusions

These findings suggest that physical activity in preschoolers could benefit their physiological needs. Thus, it is necessary to promote strategies that include the family and increase physical activity time on children's plays.
P04-09 Clustering of reported activity destinations and use of active transport among older adults

Background

Conducting everyday activities out-of-home may accumulate a large share of older adults' daily physical, especially if active transportation is used. Environmental features in home neighborhood may motivate for higher physical activity, but the role of features around destinations is less known. Our goal was to study 1) clustering of older adults' reported activity destinations, and 2) whether transport mode to a destination was associated with characteristics of destination clusters.

Methods

Data comprise AGNES study participants (901 community-dwelling people aged 75-85 years living in city of Jyväskylä, Finland; 57% women) combined with geospatial data. Using digital mapping, participants located frequently used destinations for shopping, services, and social and spiritual activities on a map, and reported transport mode (active/passive) for each. Geographic information system was used to define distance from home to each destination, to identify spatially clustered destination areas, and to assess destination areas' characteristics (urban location, intersection density, nature versatility, and the proportion of reported social/spiritual destinations of all destinations in the area). Based on their characteristics, destination areas were hierarchically categorized to area types. In mixed model, active transportation (vs. passive) was regressed for area type and adjusted for distance, car use possibility, walking difficulty in 2km, age, sex, and MMSE score.

Results

Of reported destinations within 2km from home (1278 destinations for 642 participants), 81% clustered spatially in 23 destination areas and 19% remained separate. Hierarchical clustering resulted three area types: 1) city centre (versatile activities and nature), 2) less serviced areas (versatile activities and less nature), 3) shopping areas (shopping/service activities and less nature). The proportion of destinations visited using active transportation was 63% in city centre, 68% in less serviced areas, 69% in shopping areas, and 56% for separate destinations outside the areas. Based on mixed model results, the odds for active transport use were higher when destinations located in city centre (OR = 4.8, 95%CI 1.3-17.0) or in shopping areas (OR = 11.9, 95%CI 2.6-55.6) compared to visiting locations outside spatially clustered destination areas.

Conclusion

Majority of older adults' activity destinations locate as spatially clustered. Varied destinations close to one another may promote active transport.

Background

Older adults with frailty and sarcopenia are at high risk of disability. These older adults get benefit from physical activity. However, it is challenging to get them involved in exercise interventions. The SPRINtT trial has investigated the efficacy and feasibility of a multicomponent intervention in the prevention of mobility disability in older adults with frailty and sarcopenia in 11 European countries, under the coordination of the Università Cattolica del Sacro Cuore, Italy. Altogether 1566 candidates were recruited to the SPRINtT RCT, and 142 of them in Finland.

Methods

The participants (n = 70) completed at least two years of physical activity training. The training was performed at moderate intensity and consisted of walking, strength, balance and flexibility exercises. The participants attended training two times a week at the center with the addition of home-based exercises. The training intensity increased gradually. The primary outcome of mobility disability was operationalized as an inability to complete the 400-m walk test. Secondary outcomes of physical performance were the short physical performance battery (SPPB) and handgrip strength.

Results

The results of the intervention will be revealed in spring 2020. Participants experienced that their physical performance improved during the follow-up. The physical activity program and the home-based exercises can be performed without any equipment and could, therefore, be easily implemented for practice.

Conclusions

The physical activity intervention was feasible and could be further recommended for older people with sarcopenia and physical frailty if the final results support these experiences.
P05-04 Physical activity level and sedentary time prior to cardiac ward admission among patients with cardiovascular disease and its association to all-cause mortality

Published: August 2022

Background

Low physical activity (PA) level and high sedentary time (SED) have been associated to cardiovascular (CVD) morbidity and mortality. Routinely assessing the PA-level of patients being admitted to hospital has been proposed. The aim was to explore PA-level and SED among patients prior to cardiac ward admission and whether this can predict all-cause mortality.

Methods

A longitudinal observational study of patients with ischemic heart disease, heart failure, cardiac arrhythmia, valvular heart disorder and inflammatory heart diseases treated on cardiac wards (2015-2016) in Stockholm, Sweden. Data on PA-levels and SED prior to admission were collected by validated questionnaires during inpatient care. PA level a regular week was calculated by an index (3-19 points) including everyday PA and exercise. The cut-off of insufficiently physically active was set to > 9 points. Individuals' reporting ≥7 hours of sitting a normal day were categorised as high SED. Differences in PA-level and SED between different diagnose groups were explored by Benjamini-Hochberg procedure. The associations between PA-level and SED with all-cause mortality were analysed using cox regressions, adjusting for age, sex, diagnosis group, education level, disposable income, smoking status, alcohol consumption and eating habits.

Results

Among 1148 patients with CVD, approximately 56% were considered as insufficiently physically active (>9 points). In addition, approximately half the study population were categorized as high SED (≥7 hours per day). There were differences in PA-level and SED between the various cardiovascular diagnoses, with individuals with heart failure and valvular heart disorder being in general more inactive and having higher levels of SED. A total of 200 deaths occurred during a median follow-up time of 2.6 years. The mortality was higher among those categorised as insufficiently physically active (HR 1.49, 95% CI 1.08-2.07) or high SED (HR 1.79, 95% CI 1.32-2.43) compared to those reporting sufficient PA and low SED, respectively.

Conclusion

A high amount reported insufficient PA and a high amount of SED preceding hospitalisation. There was an association between PA (negatively) and SED (positively) with all-cause mortality among patients with CVD. This highlights the prognostic value of assessing patients' PA-level and SED in clinical practice.
