Design of urban spaces and connections with sports

This paper aims to investigate the connections between sports and Urban Regeneration, and the role these connections can have in the communities of the cities. The promotion of physical activity within urban areas is today a driving force for economic and social development, and intervenes in the fragile conditions of cities. Design, as a discipline of connection between the active components of these transformations, becomes an instrument of inclusion. The interaction between people and urban space is central in promoting physical activity and a diversified community commitment. The paper investigates practices and tools of the discipline in the relationship between urban spaces and sports practices, and how this relationship leads communities to conceive new development opportunities.

Physical activity promotion in Aged care: a participatory approach

Abstract Introduction Aged care facilities (ACF) constitute an increasingly important, yet challenging setting for health promotion - given it is a highly sedentary pseudo-total institution characterized by structured daily routines within a paradigm of care for residents perceived as fragile and vulnerable. A participatory approach with residents, significant others, staff, and management might be a promising pathway to address intrapersonal, sociocultural, organizational, environmental, and political determinants of physical activity in this specific context. We will present processes and results from a research project, funded by the German Ministry of Health (2019-2023), on physical activity promotion in ACFs. Methods Our co-creation approach involved residents, significant others, staff, and management from seven nursing homes in Southern Germany. Methods included 800hrs on-site observations, semi-structured interviews (n = 31), Photovoice (n = 27 participants, n = 169 photos), as well as future workshops (n = 14) for intervention co-development (n = 14) and co-evaluation workshops (n = 7). Data analysis used reflexive thematic analysis with MaxQDA20. Results Implemented interventions (n = 57) addressed individual, social, environmental, and organizational factors. Activity promotion was integrated into care concepts and mission statements, staff work descriptions, as well as informal internal routines. Of the interventions implemented, 33% were rated as more successful, 43% as successful, and 19% as less successful than anticipated. Conclusions Participation can initiate structural and cultural change towards physical activity. However, the analyses also emphasized the critical role of staff training, along with the involvement of significant others and external service providers, as essential components for achieving sustainable change. Key messages • Participatory approaches integrate physical activity into aged care, fostering cultural shifts for resident well-being. • Success requires staff training, engaging residents’ support networks, balancing empowerment with protection.

Clean-up actions as catalysts for sustainability and physical activity promotion

Abstract Issue The convergence of global sustainability and health promotion implies integrated policies and actions. Initiatives like the European Green Deal and the UN’s Sustainable Development Goals emphasize the urgent need to address climate change while promoting health through behaviours such as physical activity (PA). Description We explore the relationship between PA, sustainability, and health outcomes, highlighting the European Green Deal’s impact on PA promotion and the 2030 Agenda for Sustainable Development’s alignment with health behaviours. In addition, we further discuss the concept of “green exercise” and provide insights about how eco-friendly initiatives (e.g., plogging) may have dual benefits in both individual and environmental domains. Results Emerging eco-friendly activities, including plogging, plalking and pliking, directly benefit the environment, while holding the potential to contribute to PA accumulation. Walking while picking up litter (i.e., plalking) can represent up to 4-5 metabolic equivalents (METs), which corresponds to performing a moderate-intensity PA. If other activities - running or cycling - are performed while picking up litter, the number of METs (i.e., >6 METs) involved may correspond to performing a vigorous-intensity PA. Lessons The physiological impact of eco-friendly activities, such as litter picking, reveals their potential as moderate to vigorous-intensity PA, favouring compliance with WHO PA recommendations (i.e., 150 min/week). Integrated policies and actions are needed to address global challenges effectively, emphasizing the interconnectedness of PA promotion, sustainability efforts, and health outcomes. Key messages • Engaging in green initiatives fosters PA and supports the United Nations’ goals for health and sustainability. • Plogging and similar eco-activities offer dual benefits: cleaner environments and healthier lifestyles.

Physical activity promotion as intersectoral planning in Milan Health Protection Agency

Abstract Issue/problem Physical activity is a protective factor for preventing Noncommunicable diseases (NCDs) and, for this reason, it plays an important role in all the different guidelines for prevention and health promotion. The Italian Regional Prevention Plans and in particular the Lombardy one promote physical activity with a systemic approach, through both upstream and downstream actions to encourage the role of communities. Description of the problem Based on the regional plan, the Health Protection Agency (HPA) of the Metropolitan City of Milan developed locally validated actions and best practices for the promotion of physical activity, through the cross-sectoral involvement of different stakeholders (health system, companies, universities, local authorities, sports associations, etc.). Results Physical activity is embedded in all lines of health promotion activities in local planning documents. Sustainable and active mobility activities have been implemented in companies and schools with a comprehensive approach. Validated regional programs (Pedibus, Walking Groups, ecc.) have been implemented in the local community, along with the construction of permanent local laboratories for physical activity, structured through the development of specific territorial networks and providing for integration with the socio-sanitary setting. Lessons Promoting physical activity becomes an opportunity to both consolidate territorial networks and to develop evidence-based health promotion actions able to meet the different health needs of the population and to produce a structural change in living contexts. Key messages • Physical activity is both a protective factor for health promotion and a tool for implementing intersectoral and equity-oriented system actions from a life-course perspective. • Promoting physical activity becomes an opportunity to consolidate territorial networks.

Population-based physical activity promotion with a focus on health equity: evidence challenges

Abstract Issue Physical activity (PA) approaches that target the entire population hold great promise for public health particularly in terms of health equity due to their broad reach. During the process of developing national recommendations for PA and PA promotion in Germany, followed by a partial update, it became evident that there is limited evidence regarding population-based PA interventions with a focus on health equity. Our objective was to present an overview of the underlying reasons for this scarcity of evidence. Methods The methodology used in the development of the German recommendations to identify evidence for population-based health equity interventions was applied. Five scientific databases were searched for reviews published between 2015-2021. References of the included reviews were checked for additional reviews. Publications without any focus on health equity were not considered. The identified evidence was summarized narratively, followed by a description of existing challenges in evaluating. Results Our search yielded 4,411 reviews, of which 79 met the inclusion criteria but 75 were excluded because approaches did not focus on the whole population, or did not address health equity. Two reviews were found in the search for gray literature. Thus, the result is a total of 6 articles. None of these reviews reported the application of a theory. The consideration of quality criteria used before, during and after the practical implementation of interventions is not common. The complexity of population-based approaches proved to be a challenge. Conclusions Overall, there is a need for more emphasis on health equity in the implementation and evaluation of population-based PA approaches. The consideration of a theoretical underpinning of such complex approaches in complex systems and the application of standardised quality criteria are an important prerequisite for the generation of evidence. Key messages • There is little evidence of population-based PA approaches aimed at health equity. • A standardized and comprehensive evaluation assessment that is accepted by all public health stakeholders is needed.

Artificial sport surfaces and adverse effects for human health. A literature review

Abstract The management of the Post-Consumer Tyres (PCTs) is still a hot topic. In 2021, the 27 EU Member States plus Norway, Switzerland, and the UK discarded 4,200 Ktons of PCTs. The main application of the rubber granules obtained from their recycling is represented by infill material in synthetic turf playgrounds. These widespread installations have become fundamental tools for the promotion of physical activity, especially among children. However, this material is in the spotlight for the presence in its composition of hazardous substances and for the small size of granules, which the European Commission classified as “microplastics”. This review aims to clarify the scientific knowledge, focusing on the assessment of the bio-accessibility/availability of hazardous chemicals and the risk assessment for users. Eligible articles reporting original data were identified in CAB Direct, Embase, PubMed, Scopus, and Web of Science. The included articles (preliminary results) variously demonstrated the presence of PAHs, metals, volatile organic compounds, and phthalates in artificial biofluids (n = 9 articles). The risk assessment for these toxicants and the potential cancer risk induction (n = 19), revealed a risk for users from absent or negligible to potential, according to the exposure scenario considered and the relative assumptions, the contaminants, the exposure route, the age of the pitch, and characteristics of the rubber granules such as origin, concentration of the different toxicants, and particle size. The assessment of the potential hazard due to the exposure to artificial sports surfaces is anything but simple. Indeed, the crumb rubber compositions may vary in different settings and over time and can be variously influenced by the climate and environmental conditions, making it difficult to quantify the possible health effects, as well as the specific mixture, the quantities, and sources responsible for them (Funded by LIFE20 GIE FR 282 - RE-PLAN CITY LIFE). Key messages • The bioccessibility of PAHs, metals, volatile organic compounds, and phthalates included in the infill material composition was variously demonstrated in literature. • The assessment of the potential risks due to the exposure to synthetic turf, revealed a risk from negligible to potential, according to the exposure scenario considered and the relative assumptions.

Urban transformation interventions for the promotion of active home-school mobility: overview

Abstract Background Active home-school mobility can contribute to a series of benefits, both for the health of children and adolescents (higher levels of physical activity, better cardio-metabolic profile, better school performance), and for the health of the general population and of environment (reduction of air pollution and greenhouse gas emissions). An overview of systematic reviews (RS) was conducted in order to evaluate mainly the effectiveness of interventions promoting active home-school mobility on physical activity, overweight/obesity, well-being and reduction of road accidents in children and adolescents. Methods The bibliographic search was carried out on the following databases: Cochrane Database of Systematic Reviews, MEDLINE, Embase and CINAHL, without any limits. Endnote software was used for the systematic reviews (SRs) selection. Data relating to the main characteristics and results of the SRs were extracted. The assessment of the methodological quality of the SRs was carried out using the “Health Evidence™ Quality Assessment Tool”. Results On the basis of the relevance and adherence to the research PICO, n. 12 systematic literature reviews evaluating effects of interventions of interest in the study population. The strategies took multiple levels into consideration, i.e. they aimed at organizing the home-school journey to encourage active mobility, as well as training and information aimed at the population under study for the promotion of physical activity. Conclusions Combined interventions appear more effective in promoting active home-school mobility with a better impact on increasing physical activity levels. Further high quality studies are necessary to investigate the impact of these interventions also on the reduction of incidence of overweight/obesity and in terms of school performance. Key messages • Policy makers should promote programs to increase active home-school transport. • Further high quality studies are necessary to investigate the impact of these interventions also on the reduction of incidence of overweight/obesity and in terms of school performance.

Reducing obesity and overweight: Subregional Policy Dialogues in the WHO European Region

Abstract In the WHO European Region, obesity and overweight stand as leading causes of disability and premature mortality. They contribute significantly to the burden of noncommunicable diseases, hindering efforts to achieve sustainable development goals related to health, including SDG goal 3.4, aiming to reduce premature mortality from NCDs by one-third by 2030. Despite some policy successes such as sugary drinks taxes, restrictions on marketing unhealthy products to children, and physical activity promotion campaigns, no country has managed to halt the rising levels of obesity. Addressing obesity requires a comprehensive approach, and WHO endeavors to support countries in implementing a wide range of policy actions across various settings. The WHO Special Initiative for NCDs and Innovation has recently adopted a subregional approach to promote evidence-based, data-informed policy action. In June 2022, it organized a series of obesity dialogues, including sessions for the Western Balkans. This session will outline the methods and outcomes of these dialogues, including stakeholder engagement, presentation of the latest obesity data, evidence-based policy recommendations, and the process of prioritizing policy options with decision-makers. It will consider the lessons learned from this process, offering insights not only for the health agenda but also for addressing other complex public health, environmental, or social challenges, which require multisectoral collaboration and comprehensive, policy actions on many levels.

Using Qualitative Geospatial Methods to Explore Physical Activity in Children with Developmental Disabilities: A Feasibility Study

Children with developmental disabilities (DDs) experience barriers to physical activity (PA) participation. Greater contextual information regarding their PA behaviors is needed for effective PA promotion. We investigated the feasibility of using activity trackers and Global Positioning Systems (GPS) devices with follow-up interviews to explore PA behaviors in children with DDs. Fifteen children with DDs (aged 10 ± 2 years) wore an activity tracker and GPS device for 7 days. Data were time-aligned to measure PA and identify PA locations. Maps were created to guide follow-up semi-structured interviews with the children and their parents/guardians to understand PA contexts and perceptions of daily PA. The children took 8680 ± 4267 steps/day across 6 ± 1 days. The children provided preferences for PA locations and the parents/guardians gave context by expressing how DDs affect PA and identifying environmental factors in PA locations. The children with DDs who lived near parks, participated in PA that leveraged the strengths of their individual skillsets, and had parents/guardians who provided social support had more positive PA experiences. Combining activity tracking and GPS data with follow-up map-based interviews is feasible to explore PA behaviors and the experiences of children with DDs. This methodology may provide novel insight into daily PA in children with DDs, which can inform how future interventions can support them to be more active and have positive experiences while being active.

Adolescents’ physical activity during and beyond the Covid-19 pandemic: a qualitative study exploring the experiences of young people living in the context of socioeconomic deprivation

BackgroundAdolescent physical activity levels are low and are shown to decline with age into adulthood. Emerging literature suggests these trends were exacerbated during the Covid-19 pandemic. We aimed to understand, from the perspective of adolescents living in deprived communities, whether the Covid-19 pandemic influenced their physical behaviour and explore their ideas for physical activity promotion moving forward.MethodsPurposive sampling was used to recruit older adolescents (13-18-year-old) living in one of the 20% most deprived areas in the UK, as defined by the UK Index of Multiple Deprivation. A mix of in-person and online one-to-one semi-structured interviews were conducted between July 2021- March 2022. Interviews were audio-recorded, transcribed verbatim and anonymised. Data were imported into Nvivo software and analysed drawing on Braun and Clarke’s six phases of thematic analysis.ResultsThe sample consisted of 16 adolescents and included a mix of genders. The following themes were generated during the data analysis: (1) Physical activity behaviour in everyday life (prepandemic), (2) The impact of Covid-19 on physical activity (during) and (3) Young people’s ideas about physical activity promotion (moving forward). Participants described themselves as inactive, with their activity limited to active travel, informal activity and physical education. Experiences of the pandemic were largely negative, impacting participants’ physical and mental health. Ideas around physical activity promotion ranged from the individual to the societal level.ConclusionsOur findings suggest the Covid-19 pandemic had a major impact on young people living in the context of socioeconomic deprivation. Physical activity promotion efforts should focus on school-based opportunities and the provision of safe and low-cost opportunities in socioeconomically deprived areas. As we aim to build back from the Covid-19 pandemic, supporting young people living in socioeconomically deprived communities should be prioritised.

Promoting and managing youth jogging groups in Tanzania: can we bank on social capital?

ABSTRACT Rationale/Purpose The article examined the manner and the extent to which social capital influenced the formation, promotion and management of jogging groups in Tanzania. Design/Methodology/Approach A qualitative approach was used to collect and analyse data, whereby interviews, focus group discussions and observations were used as data collection methods. Social capital theory (SCT) guided this study. Findings Social capital manifested in features such as friendship and neighbourhood ties, work connections and association memberships, norms and values like trust and respect facilitate the formation, promotion, and management of physical activity in urban Tanzania through Youth Jogging Groups (YJG). Practical Implication State and non-state actors like private institutions, parents, and community residents should provide training, moral guidance and financial support to existing youth jogging groups’ initiatives and goals. This support has practical contributions towards addressing multiple health-related challenges facilitated by urban sedentary lifestyles. Research contribution Well-established social capital features among urban youth in the global youth serve a critical role in mobilising, managing, and surviving collective physical activity such as group jogging.

Associations of Wearable Activity Tracker Use With Physical Activity and Health Outcomes in Patients With Cancer: Findings from a Population-Based Survey Study.

Physical inactivity is a global issue for cancer survivors. Wearable activity trackers are promising to address physical inactivity by providing real-time feedback on physical activity and offering opportunities for self-monitoring and goal setting. Meta-analysis has reported the effects of interventions that incorporate wearable activity trackers on improved physical inactivity and related health outcomes (eg, BMI, anxiety and depression, and self-rated health status). However, wearable activity trackers were often used as an adjunct to physical activity interventions, and the effectiveness of wearable activity trackers alone is unknown. This study aims to determine the association of wearable activity trackers with physical activity and health outcomes in patients with cancer. Data from 957 cancer survivors from the Health Information National Trends Survey-Surveillance, Epidemiology, and End Results (HINTS-SEER) were analyzed. The outcome variables examined were time spent in moderate to vigorous physical activity, weekly frequency of strength training, BMI, anxiety and depression levels, and self-assessed health status. The primary independent variable was whether cancer survivors had used wearable activity trackers within the past 12 months. Design-based linear regression for continuous outcome variables and ordinal logistic regression for ordinal outcome variables were conducted to determine the associations after controlling for sociodemographic, cancer-related, and health-related factors. All data analyses accounted for the complex survey design and sample weights. Only 29% of cancer survivors reported wearable activity tracker use. Bivariate analyses showed that younger age (P<.001), higher education (P=.04), higher income (P<.001), and an employed status (P<.001) were significantly associated with wearable activity tracker use. Wearable activity tracker use was significantly associated with higher time spent in moderate to vigorous physical activity (adjusted =37.94, 95% CI 8.38-67.5; P=.01), more frequent strength training per week (adjusted odds ratio [OR] 1.50, 95% CI 1.09-2.06; P=.01), and better self-rated health status (adjusted OR 1.58, 95% CI 1.09-2.29; P=.01), but not with BMI or anxiety and depression. This study suggests that the uptake of wearable activity trackers is low and highlights the digital divide among patients with cancer. This study has confirmed the associations of wearable activity tracker use with physical activity and self-rated health, supporting using wearable activity trackers as a promising tool to facilitate physical activity promotion.

The relevance of the United Nations' Sustainable Development Goals in the promotion of sport, physical activity, and recreation in Canada.

Canada is unique in that it has established four national strategies in support of sport, physical activity, and/or recreation (SPAR). Though some of these strategies identify potential social and environmental correlates of SPAR, and articulate societal outcomes such as changes in behaviour and health, there are no explicit links to larger global initiatives such as the United Nations' Sustainable Development Goals (SDGs). Given that countries are expected to propose a plan for addressing the 17 SDGs, and that obvious overlap exists between several of the proposed development goals and SPAR, Canada should consider whether common indicators can be identified across these strategies and the SDGs simultaneously to facilitate more efficient and effective action. To date, the only SPAR-related indicator proposed in the Canadian plan for SDGs is the health benefit(s) associated with engagement in daily physical activity under Goal 3. Taking an evidence-informed approach for identifying those SDGs for which there are synergies with existing SPAR strategies, we suggest that other goals addressing gender equality, sustainable communities, climate action, life on the land, and peace and justice also share co-benefits with SPAR in Canada. Thus, any revisions to the existing SPAR strategies should identify linkages to the SDGs and indicators.

Progress in physical activity research, policy, and surveillance in Canada: The global observatory for physical activity – GoPA!

BackgroundThe purpose of this paper is to examine the evolution of physical activity research and the comprehensiveness of national physical activity policies and surveillance systems in Canada.MethodsA systematic review was conducted by the Global Observatory for Physical Activity (GoPA! ) on physical activity and health publications between 1950 and 2019. Findings from Canada were extracted and included in the present analysis. The number of articles published, female researcher involvement in authorship, author institution affiliations, and publication themes were examined. Policies were evaluated by determining if there was a standalone physical activity plan and if national guidelines existed. Surveillance systems were assessed for periodicity, instruments used, and age inclusivity.ResultsOut of 23,000 + publications analyzed worldwide; 1,962 included data collected in Canada. Physical activity research in Canada increased considerably from the 2000s to 2010s (543 articles vs. 1,288 articles), but an apparent stabilization has been observed more recently. Most physical activity publications in Canada focused on surveillance (37%), with fewer articles on policy (8%) and interventions (7%). The proportion of female first authors increased from 38% in the 1980s to 60% in the last decade. However, females remain the minority for senior authors. With respect to policy, “A Common Vision” is Canada’s national plan, which has a singular policy focus on physical activity. National surveillance data is collected regularly with both the Canadian Health Measures Survey (CHMS) and the Canadian Community Health Survey. In addition to self-report, the CHMS also collects accelerometer data from participants.ConclusionThrough collaborative and coordinated action, Canada remains well equipped to tackle physical inactivity. Continued efforts are needed to enhance sustained awareness of existing physical activity promotion resources to increase physical activity.

A Bibliometric Analysis of Research Trends in Aging and Leisure Activities from 2000 to 2023.

Physical and leisure activities are vital for active aging. Leisure activities among the aging population have received attention from scholars in the recent past. However, the research contributions and trends in this field are unknown. Therefore, a bibliometric analysis was conducted to explore the scholarly contributions in aging and leisure activities to identify the research output trends, assess thematic focuses, and analyze research collaboration patterns. We extracted data from the Scopus database for the period 2000-2023 and identified 443 articles focusing on aging and leisure activities. Tools, such as bibliographical coupling networks and thematic analysis, were applied using R and Biblioshiny to uncover core themes and connections. There has been a significant increase in research output since 2021, with contributions from numerous authors and countries, particularly the United States and China. Thematic analysis reveals central themes, such as physical activity, successful aging, and cognition. This analysis reveals the evolving nature of scholarly discussions in aging and leisure, highlighting key themes, such as physical activity, cognitive aging, and health promotion. The findings emphasize the growing interest and global collaboration in this interdisciplinary research domain.

A ATIVIDADE FÍSICA COMO FERRAMENTA DE PROMOÇÃO DA SAÚDE E QUALIDADE DE VIDA PARA PESSOAS IDOSAS

Demographic ageing is defined by the increase in the proportion of elderly people in the total population. This demographic context highlights the need to create specific policies and actions to meet the demands of this growing population. The aim of this study is to review the existing literature on the use of physical activity to promote health and quality of life in the elderly. However, to understand the recurring physiological changes of the ageing process and the benefits of physical activity for improving the quality of life of the population in question. Therefore, this study is justified by the need to encourage physical activity among the elderly population, with the aim of minimizing the negative impacts of sedentary lifestyles and promoting healthy and active ageing. This article is a literature review with a qualitative approach. This study analyzed 20 articles, the findings of which indicate that physical activity is an important tool for promoting health and improving quality of life among the elderly. Based on the theoretical foundation, the benefits of practicing physical activities in improving basic daily activities were discussed, as well as their relationship with physiological changes. Evidence shows that regular physical exercise can mitigate the effects of loss of muscle mass and the risk of chronic diseases, as well as improving functional independence and mental well-being. In view of this, the promotion of physical activity should be a priority in public policy, with concrete incentives and an integrated approach among health professionals. It can be concluded that including physical exercise in everyday life not only prevents disease, but also contributes to healthier and more active ageing.

Effects of activity participation and cognitive levels on depression in middle-aged and older adults with chronic illness: a national cross-sectional study.

The world population is rapidly aging, and depression mainly affects middle-aged and older adults with chronic diseases and cognitive impairments. The sample for this study was obtained from the China Health and Retirement Longitudinal Study (CHARLS) public database. The sample size for inclusion was 12,767. There were 6,773 females and 5,994 males, with an overall low level of education. This study aims to provide a theoretical and practical reference basis for the clinical non-pharmacological treatment of depression in middle-aged and older adults (age ≥ 50 years) with chronic diseases. Additionally, the study seeks to promote the development of mental health interventions for middle-aged and older adults (age ≥ 50 years) with chronic diseases, ultimately enhancing the sense of well-being and quality of life for this demographic. Cognitive functioning and depressive symptoms of the study participants were assessed using the Mini-Mental State Examination Scale (MMSE) and the short version of the Center for Epidemiological Studies Depression Scale (CESD-10). Binary logistic regression results showed that among middle-aged and older adults (age ≥ 50 years) with chronic diseases, participation in physical activity [OR = 1.397; 95% CI (1.181-1.651); p < 0.05] was more effective than participation in social activities [OR = 0.997; 95% CI (0.924-1.076); p < 0.05] for preventing depression. Those with cognitive impairment [OR = 1.206; 95% CI (1.089-1.335); p < 0.05] were more likely to experience depression than those without cognitive impairment. Activity participation (physical activity and social activity) had a more significant effect on mild and moderate depression compared to no depression, and cognitive level had a more pronounced effect on moderate depression [OR = 1.491; 95% CI (1.278-1.740); p < 0.05] and major depression [OR = 2.231; 95% CI (1.282-3.884); p < 0.05]. Within the specific cohort of middle-aged and older adults (age ≥ 50 years) with chronic diseases, both activity participation and cognitive level exert a significant influence on the prevention and intervention of depression. Engagement in physical activity, participation in social activities, and enhanced cognitive functioning emerged as protective factors against depression. Therefore, the policy-maker should strengthen the prevention and treatment of depression in a comprehensive manner through the promotion of physical and social activities and the enhancement of cognitive level, so as to safeguard the mental health of middle-aged and older adults with chronic diseases.

The construction of a physical literacy assessment index system for junior high school students: a Chinese study

In recent years, the internalisation of education in China has led to an increase in the prevalence of a highly competitive, test-focused approach to learning. This has had a detrimental impact on the physical health and wellbeing of children and adolescents in China, resulting in a concerning lack of physical literacy among junior high school students. Accordingly, the objective of this study is to construct an evaluation index system for physical literacy in junior high school students with Chinese characteristics, quantify the relative importance of each domain, and provide a framework for students to assess and self-evaluate the sustainable development of their physical literacy. The indicator system was modelled on CAPL-2, and valid indicators were extracted from the literature. A pre-selected indicator system for physical literacy in junior high school students was constructed through three rounds of Delphi expert questionnaire surveys (48 questionnaires were distributed in total). A total of 16 experts participated in all three rounds of the surveys until a consensus was reached on the indicators, resulting in the establishment of a hierarchical analysis-based theoretical model. This was developed using the experts’ opinions and determined the items to be subdomains and weights. The AHP was employed to ascertain the relative importance of the subdomains and items within the assessment system. The index weight scores of the Chinese junior high school students’ physical literacy assessment index system are aligned with the core tenet of the physical literacy concept, comprising four primary indicators, eight secondary indicators, and 26 tertiary indicators. The weights of the physical literacy evaluation indexes for junior high school students in China were calculated using the AHP to establish a progressive hierarchical model and the consistency test. The primary indicators were found to be in the following order of importance: Physical Competence (29.82%) > Motivation and Confidence (29.64%) > Knowledge and Understanding (20.27%) = Daily Behavior (20.27%). The system is an effective means of evaluating the impact of physical activity and health promotion among junior high school students, and it effectively addresses the needs of this age group in these areas. It provides a comprehensive assessment of the effects of physical activity and health promotion among junior high school students, and it offers a scientific foundation for the development of precise and individualized physical activity and health promotion programs.

The associations between dairy product intake, fatigue status, and physical activity among postpartum women in Saudi Arabia: a cross-sectional study

BackgroundFatigue is a major issue that affects women during the postpartum period. A healthy dietary pattern and increased physical activity (PA) are commonly recommended lifestyle modifications to promote health during this time. However, little is known about the interrelationship between dairy product intake, PA level, and postpartum fatigue (PPF) among women. The aim of this study was to evaluate whether PPF is associated with dairy product intake in relation to PA level.MethodsA total of 242 women were included in this cross-sectional study. Data related to dairy product intake and PA were collected using a food frequency questionnaire and the International Physical Activity Questionnaire—Short Form, respectively. PPF was assessed using the Fatigue Severity Scale. Logistic regression models were used to examine associations between the intake of dairy products and PPF among women engaged in low, moderate, and high levels of PA while controlling for potential confounders.ResultsHigher consumption rates of yogurt and total dairy predicted lower odds of PPF in women engaged in moderate levels of PA (aOR = 0.24 [95% CI = 0.07, 0.86] and 0.70 [95% CI = 0.53, 0.93], respectively). In women engaged in high levels of PA, lower odds of experiencing PPF were predicted by higher consumption rates of milk (aOR = 0.24 [95% CI = 0.07, 0.89]), yogurt (aOR = 0.21 [95% CI = 0.05, 0.83]), laban (aOR = 0.16 [95% CI = 0.03, 0.86]), and total dairy (aOR = 0.66 [95% CI = 0.47, 0.92]). However, no association was observed between dairy product intake and PPF in women with low levels of PA.ConclusionsHigher consumption rates of dairy products were associated with lower odds for experiencing PPF, particularly for women engaged in moderate to high levels of PA. These findings support nutritional and PA promotion programs to moderate issues with PPF. However, the cross-sectional design of this study could limit the ability to infer causality between dairy intake, PA, and PPF. Further longitudinal studies are needed to establish causality and explore the mechanisms underlying these associations.

Effect of a Multifactorial Weight Loss Intervention on HDL Cholesterol Efflux Capacity and Immunosenescence: A Randomized Controlled Trial

Objective Life expectancy and obesity prevalence are increasing worldwide, leading to an increase in the prevalence of cardiovascular disease. High-density lipoprotein (HDL) functionality and immunosenescence play key roles in cardiovascular disease, longevity, and quality of aging. Both molecular hallmarks of aging are impacted by obesity and metabolic syndrome and can be modulated by lifestyle. We aimed to evaluate the effect of a lifestyle intervention focused on an energy-reduced Mediterranean diet (erMedDiet), physical activity (PA), and behavioral support on HDL cholesterol efflux capacity (CEC) and immunosenescence. Method CEC and immunosenescent T cells were determined in 60 participants from the control group (CG) and 56 from the intervention group (IG) of the PREDIMED-Plus trial at baseline and after 1 and 3 years of follow-up. PREDIMED-Plus is a randomized, controlled, parallel-group trial with an IG of erMedDiet, PA promotion, and behavioral support for weight loss and a CG of usual primary care advice. The sample included 116 volunteers from the PREDIMED-Plus-IMDEA subsample of the PREDIMED-Plus trial. Men aged 55 to 75 years and women aged 60 to 75 years with a body mass index between 27 and 40 kg/m2 and metabolic syndrome were included. Results Participants within the IG had significantly improved CEC (2.42% and 10.69% after 1 and 3 years of follow-up) and a decreased in senescent T cell profile (−3.32% ± 12.54% and −6.74% ± 11.2%, p < 0.001, after 1 and 3 years of follow-up). Baseline obesity status impacted the response to the intervention. Conclusions A weight loss intervention program with erMedDiet and PA ameliorated senescence markers.
