Built Environment Approaches to Increase Physical Activity: A Science Advisory From the American Heart Association

Adaptations to a statewide walking program: Use of iterative feedback cycles between research and delivery systems improves fit for over 10 years

FitEx is an 8-week, group-based physical activity and fruit and vegetable consumption program co-created and implemented with the Cooperative Extension System. Effectiveness and delivery personnel perceptions of the program are promising; however, ongoing adaptations are required to continuously meet shifting needs of both researchers and delivery systems. We applied the APDER iterative cycles of implementation over 15 years to understand dynamic and ongoing adaptations as well as implications for FitEx sustainability. Each year, an IRPP between delivery (FitEx deliverers) and research (FitEx developers) systems shared feedback on program core elements and strategies for adaptation through regular team meetings, emails, and evaluations. While the core elements (delivering to groups, goal setting, feedback, and self-monitoring) of FitEx remained consistent, changes were made to address logistical factors, emergent research questions, and technological advancements. For example, program deliverers suggested decreasing training time and making program content available on demand rather than through traditional in-person training. Using APDER with a long-standing IRPP allowed the delivery system to provide feedback to program developers to co-create ongoing adaptations and data-driven decisions. Future work in response to shifting needs includes Fitbit integration and technological updates to the usability of the FitEx platform. Our aim is to report the 15+ years of applying the Assess, Plan, Do, Evaluate, Report (APDER) process with an integrated research-practice partnership (IRPP) for co-creation of ongoing adaptations of FitEx and to share methods for capturing relevant data for decision-making to integrate health promotion programs in community settings.

Greenway interventions effectively enhance physical activity levels-A systematic review with meta-analysis

Background

Previous studies have examined the impact of greenway interventions on physical activity (PA); however, the results have been inconclusive. In order to address this issue, our study conducted a systematic review with meta-analysis to thoroughly evaluate the evidence and determine the effectiveness of greenway interventions in promoting PA.

Methods

We conducted a comprehensive search of literature databases, such as Web of Science, EMBASE, PubMed (via Medline), Cochrane Library, and Scopus, up to June 15, 2023. To synthesize the available evidence, we performed a meta-analysis using a random effects model. The quality of the included studies was assessed using the criteria developed by the Agency for Healthcare Research and Quality and the Newcastle-Ottawa Scale.

Results

A total of 9 publications were identified, involving 6, 589 individuals. The overall quality of most included studies was rated as moderate to high. Our study found that the greenway was effective in promoting PA among participants. Specifically, active travel (AT) showed a standard mean difference (SMD) of 0.10 [95% confidence interval (CI): 0.04 to 0.17], moderate-to-vigorous PA had an SMD of 0.11 (95% CI: 0.02 to 0.20), and total PA had an SMD of 0.14 (95% CI: 0.06 to 0.21). We also observed significant differences in AT levels among participants based on greenway characteristics, exposure distance, exposure duration, and male-to-female ratio.

Discussion

Newly developed or upgraded greenways have been shown to effectively promote PA. Additionally, research suggests that the longer a greenway has been in existence, the greater the benefits it provides for PA. As a result, the construction of greenways should be recognized as an effective public health intervention.

Demonstration Projects to Test Built Environment Changes: A Systematic Review

CONTEXT

Built environment interventions (pedestrian/bicycle infrastructure and enhanced access) mitigate barriers to physical activity by making the healthy choice the default choice. Demonstration projects (eg, temporary pedestrian lanes or sidewalks marked with tape) are used to test these interventions before making permanent changes. However, it is unknown whether demonstration projects lead to desired built environment changes.

OBJECTIVE

To systematically review the literature to determine outcomes and overall public health impacts of demonstration projects and whether they lead to permanent changes to the built environment.

DESIGN

Systematic review, conducted from March to September 2022 by searching PubMed and EBSCOhost for peer-reviewed literature and Google for gray (non-peer-reviewed) literature. Inclusion criteria were policy, systems, or environmental interventions; temporary implementation; and presence of evaluation data. Exclusion criteria were individual/interpersonal-level interventions, permanent implementation, and absence of evaluation data. Two authors coded for inclusion/exclusion and resolved discrepancies, coded a portion of included sources and resolved discrepancies, refined coding guide definitions, and coded remaining sources.

MAIN OUTCOME MEASURES

Data were extracted based on the expanded RE-AIM (Reach, Effectiveness, Adoption, Implementation, Maintenance) framework, which incorporates constructs of the Implementation Outcomes Framework (acceptability, appropriateness, feasibility).

RESULTS

Gray (N = 23) and peer-reviewed (N = 1) sources describing unique demonstration projects (N = 31) met inclusion criteria. Projects tested built environment interventions including traffic calming measures, crosswalks, bike lanes, intersection design, and trails. Sources primarily reported effectiveness (typically improved safety), maintenance, acceptability, and appropriateness. Most sources did not report projects leading to permanent changes to the built environment.

CONCLUSIONS

Based on inconsistent reporting of key outcomes (number of community members reached, changes to physical activity levels), overall impacts are unknown. Most demonstration projects captured community members' feedback, which was typically positive, but it is unknown whether feedback led to long-term changes. We recommend providing improved demonstration project guidance for practitioners to facilitate robust data collection, including suggested evaluation methods and tools.

Impact of Neighborhood on Cardiovascular Health: A Contemporary Narrative Review

PURPOSE OF REVIEW

This review summarizes approaches towards neighborhood characterization in relation to cardiovascular health; contemporary investigations relating neighborhood factors to cardiovascular risk and disease; and initiatives to support community-based interventions to address neighborhood-based social determinants related to cardiovascular health.

RECENT FINDINGS

Neighborhoods may be characterized by Census-derived measures, geospatial data, historical databases, and metrics that incorporate data from electronic medical records and health information exchange databases. Current research has examined neighborhood determinants spanning racial segregation, access to healthcare and food, educational opportunities, physical and built environment, and social environment, and their relations to cardiovascular health and associated outcomes. Community-based interventions have potential to alleviate health disparities but remain limited by implementation challenges. Consideration of neighborhood context is essential in the design of interventions to prevent cardiovascular disease (CVD) and promote health equity. Partnership with community stakeholders may enhance implementation of programs addressing neighborhood-based health determinants.

The Weight of Place: Built Environment Correlates of Obesity and Diabetes

In recent decades, the prevalence of obesity and diabetes has risen substantially in North America and worldwide. To address these dual epidemics, researchers and policymakers alike have been searching for effective means to promote healthy lifestyles at a population level. As a consequence, there has been a proliferation of research examining how the "built" environment in which we live influences physical activity levels, by promoting active forms of transportation, such as walking and cycling, over passive ones, such as car use. Shifting the transportation choices of local residents may mean that more members of the population can participate in physical activity during their daily routine without structured exercise programs. Increasingly, this line of research has considered the downstream metabolic consequences of the environment in which we live, raising the possibility that "healthier" community designs could help mitigate the rise in obesity and diabetes prevalence. This review discusses the evidence examining the relationship between the built environment, physical activity, and obesity-related diseases. We also consider how other environmental factors may interact with the built environment to influence metabolic health, highlighting challenges in understanding causal relationships in this area of research.

Built environment approaches: Extension personnel's preferences, barriers, and facilitators

Introduction

Interventions that modify the built environment can increase population physical activity levels and prevent chronic disease. The national Cooperative Extension System is poised to implement built environment approaches (i.e., pedestrian/bicycle infrastructure and enhanced access to physical activity spaces), but implementation strategies (i.e., methods or techniques to move research to practice) are needed to improve uptake. Effective implementation strategies address relevant barriers and capitalize on facilitators. The purpose of this study was to understand 1) barriers and facilitators to implementing built environment approaches in two state Extension systems, 2) preferences for built environment approaches, and 3) preferences for implementation strategies.

Methods

A cross-sectional online survey was used to understand Extension personnel's preferences for and barriers and facilitators to built environment approaches through a mixed-methods study design. This work was informed by anthropological inquiry as the overall research philosophy, and by the Health Impact Pyramid, Leeman et al.'s classification of implementation strategies, and the Consolidated Framework for Implementation Research as the theoretical frameworks. The survey was distributed to eligible Extension personnel (n = 42) in two states. Quantitative data analysis consisted of numbers/proportions and Friedman tests. Qualitative analysis was completed through a rapid deductive approach to quickly produce actionable results.

Results

Fourteen respondents (33%) completed the survey. Most had not implemented physical activity interventions in their communities or had implemented only individual-level interventions, though were interested in implementing built environment approaches. Benches, playground improvements, and crosswalks were the most desired approaches, while facilitation, assessing community strengths and needs, and technical assistance were desired implementation strategies. The most common barriers were relative priority and available resources; facilitators were external policy and incentives and implementation climate.

Discussion

Extension personnel are receptive to built environment approaches and engaged with community coalitions. Yet, invested parties prefer individual-level interventions, and agents perceive a lack of resources for implementation. Implementation strategies that build capacity in both the Extension system and community coalitions may address these barriers through increasing relative priority and sharing existing resources. This work is a first step toward compiling implementation strategies to address relevant barriers to built environment approaches in community settings.

Assessing Park Quality with a Wearable Video Device and an Unmanned Aerial System

Parks are ideal places for promoting physical activity, which is vital for achieving and sustaining good health. Thus, it is important to develop and provide the best methods for assessing aspects of parks that could influence physical activity. This study examined the use of high-tech video capture for describing park quality. Videos were obtained with a wearable video device (WVD) and an unmanned aerial system (UAS) at 28 and 17 parks, respectively. In-person audits of park attributes were performed using the Physical Activity Readiness Assessment (PARA) instrument while video was simultaneously captured. The PARA provides quality ratings of park attributes that range from poor to good. Kappa statistics were calculated to compare in-person PARA outcomes with PARA outcomes obtained by reviewing the WVD and UAS videos. Substantial and almost-perfect agreements were found between WVD and in-person PARAs on the quality of features and amenities and the severity of incivilities. Agreements between UAS and in-person PARAs on feature and amenity quality and incivility severity were unacceptable (mostly fair and moderate). In conclusion, being able to reliably assess park quality using video provides advantages over in-person assessments (e.g., retrospective analysis). In addition, it sets up the possibility of utilizing computer vision to automate the video analysis process.

The Relationship Between Environmental Exposures and Post-Stroke Physical Activity

INTRODUCTION

Post-stroke physical activity has widespread health benefits. Environmental exposures may shape post-stroke physical activity behavior. This study investigates the relationships between environmental exposures and post-stroke physical activity.

METHODS

Stroke survivors (n=374) from a cohort of Black and White adults with post-stroke accelerometer data (2009-2013) were eligible for this study. Participants' home addresses were linked with secondary data to capture environmental characteristics, including annual density of neighborhood resources (e.g., parks, physical activity facilities, and intellectual stimulation destinations), 2010 neighborhood SES, 2010 neighborhood crime, and daily information on extremely cold days. Post-stroke light physical activity and moderate-to-vigorous physical activity were captured using accelerometers over a 7-day period. Linear regression and 2-part/hurdle models were used to estimate the relationship between the density of neighborhood resources with light physical activity and with moderate-to-vigorous physical activity, respectively. Analyses were conducted in 2021.

RESULTS

A 10% increase in the number of extremely cold days was associated with 6.37 fewer minutes of daily light physical activity (95% CI= -11.37, -1.37). A 1-SD increase in neighborhood SES was associated with greater odds (OR=1.10, 95% CI=1.02, 1.19) of doing any moderate-to-vigorous physical activity. Among participants obtaining any moderate-to-vigorous physical activity, a 1-unit (count/km²) increase in destinations for intellectual stimulation was associated with 0.99 (95% CI=0.02, 1.97) more minutes of daily moderate-to-vigorous physical activity. All other environmental exposures were not associated with post-stroke light physical activity or moderate-to-vigorous physical activity.

CONCLUSIONS

Environmental exposures may facilitate physical activity participation among stroke survivors. This study found that weather, neighborhood SES, and proximity to destinations for intellectual stimulation were associated with physical activity over and above individual factors.

Have Paved Trails and Protected Bike Lanes Led to More Bicycling in Atlanta?: A Generalized Synthetic-Control Analysis

BACKGROUND

Bicycling is an important form of physical activity in populations. Research assessing the effect of infrastructure on bicycling with high-resolution smartphone data is emerging in several places, but it remains limited in low-bicycling US settings, including the Southeastern US. The Atlanta area has been expanding its bicycle infrastructure, including off-street paved trails such as the Atlanta BeltLine and some protected bike lanes.

METHODS

Using the generalized synthetic-control method, we estimated effects of five groups of off-street paved trails and protected bike lanes on bicycle ridership in their corresponding areas. To measure bicycling, we used 2 years (October 1, 2016 to September 30, 2018) of monthly Strava data in Atlanta's urban core along with data from 15 on-the-ground counters to adjust for spatiotemporal variation in app use.

RESULTS

Considering all infrastructure as one joint intervention, an estimated 1.10 (95% confidence interval [CI]: 0.99, 1.18) times more bicycle-distance was ridden than would have been expected in the same areas had the infrastructure not been built, when defining treatment areas by the narrower of two definitions (defined in text). The Atlanta BeltLine Westside Trail and Proctor Creek Greenway had especially strong effect estimates, e.g., ratios of 1.45 (95% CI: 1.12, 1.86) and 1.55 (1.10, 2.14) under each treatment-area definition, respectively. We estimated that other infrastructure had weaker positive or no effects on bicycle-distance ridden.

CONCLUSIONS

This study advances research on the topic because of its setting in the US Southeast, simultaneous assessment of several infrastructure groups, and data-driven approach to estimating effects. See video abstract at, http://links.lww.com/EDE/B936.

Implementation Strategies to Support Built Environment Approaches in Community Settings

BACKGROUND

Built environment approaches are recommended to improve population physical activity levels. Implementation strategies are needed to improve uptake, but little is known about effective strategies to translate research to practice in community settings.

PURPOSE

Inform implementation strategies through understanding delivery agents' perceptions of (1) built environment approaches, (2) a toolkit developed to support implementation, and (3) other required implementation strategies.

METHOD

A toolkit was developed to detail the process of partnering to change the built environment and provide examples of built environment approaches (e.g., walking paths, traffic calming). Data were collected through focus groups (N = 3) with Extension Agents (n = 46) in 2020. The semi-structured focus group script was based on the Consolidated Framework for Implementation Research and the Technology Acceptance model. Rapid content analysis techniques and a deductive, grounded theory approach were used to interpret the data. Results. Focus groups generated meaning units coded into themes of perceptions of the intervention (subthemes: barriers, resources needed, and facilitators) and perceptions of the toolkit (subthemes: components to add, positive perceptions, and helpful components). The most common resources needed were coalition guidance and funding.

CONCLUSION

Agents experience barriers and facilitators to implementing built environment approaches and have specific needs for support. Based on the results, we created implementation strategies: (1) Places for Physical Activity toolkit, (2) Coalition Coaching, and (3) Mini-Grants. Future work is needed to investigate the effectiveness of these implementation strategies.

Heart Disease and Stroke Statistics-2022 Update: A Report From the American Heart Association

BACKGROUND

The American Heart Association, in conjunction with the National Institutes of Health, annually reports the most up-to-date statistics related to heart disease, stroke, and cardiovascular risk factors, including core health behaviors (smoking, physical activity, diet, and weight) and health factors (cholesterol, blood pressure, and glucose control) that contribute to cardiovascular health. The Statistical Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, congenital heart disease, rhythm disorders, subclinical atherosclerosis, coronary heart disease, heart failure, valvular disease, venous disease, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs).

METHODS

The American Heart Association, through its Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States to provide the most current information available in the annual Statistical Update. The 2022 Statistical Update is the product of a full year's worth of effort by dedicated volunteer clinicians and scientists, committed government professionals, and American Heart Association staff members. This year's edition includes data on the monitoring and benefits of cardiovascular health in the population and an enhanced focus on social determinants of health, adverse pregnancy outcomes, vascular contributions to brain health, and the global burden of cardiovascular disease and healthy life expectancy.

RESULTS

Each of the chapters in the Statistical Update focuses on a different topic related to heart disease and stroke statistics.

CONCLUSIONS

The Statistical Update represents a critical resource for the lay public, policymakers, media professionals, clinicians, health care administrators, researchers, health advocates, and others seeking the best available data on these factors and conditions.

Does providing everyone with free-of-charge organised exercise opportunities work in public health?

BACKGROUND AND PURPOSE

Population-level initiatives of free-of-charge organised exercise have been implemented to encourage residents to take up regular physical activity. However, there exists a paucity of evidence on the ability of these interventions to attract and engage residents, especially targeted subgroups. Seeking to contribute to this evidence base, we evaluated a proportionate universal programme providing free exercise sessions, Leeds Let's Get Active.

METHODS

Descriptive statistics were used to summarise the programme data and participants. Time to event, count and logistic regression models examined how different population subgroups engaged with the programme in terms of number of entries, weekly participation rates and drop-off patterns.

RESULTS

51,874 adult residents registered to the programme and provided baseline data (2013-2016). A small proportion (1.6%) attended the free sessions on a weekly basis. Higher participation rates were estimated for the groups of males, retired and non-inactive participants. A neighbourhood-level deprivation status was found to have no marginal effect on the level and frequency of participation, but to be negatively associated with participation drop-off (HR 0.93, 95% CI 0.89-0.97, p = 0.001).

CONCLUSIONS

Providing everyone with free-of-charge organised exercise opportunities in public leisure centres located in deprived areas can attract large volumes of residents, but may not sufficiently encourage adults, especially inactive residents and those living in disadvantaged neighbourhoods, to take up regular exercise.

Workplace neighbourhood built-environment attributes and sitting at work and for transport among Japanese desk-based workers

Workplace settings—both internal and external—can influence how workers are physically active or sedentary. Although research has identified some indoor environmental attributes associated with sitting at work, few studies have examined associations of workplace neighbourhood built-environment attributes with workplace sitting time. We examined the cross-sectional associations of perceived and objective workplace neighbourhood built-environment attributes with sitting time at work and for transport among desk-based workers in Japan. Data were collected from a nationwide online survey. The Abbreviated Neighborhood Environment Walkability Scale (n = 2137) and Walk Score® (for a subsample of participants; n = 1163) were used to assess perceived and objective built-environment attributes of workplace neighbourhoods. Self-reported daily average sitting time at work, in cars and in public transport was measured using a Japanese validated questionnaire. Linear regression models estimated the associations of workplace neighbourhood built-environment attributes with sitting time. All perceived workplace neighbourhood built-environment attributes were positively correlated with Walk Score®. However, statistically significant associations with Walk Score® were found for sitting for transport but not for sitting at work. Workers who perceived their workplace neighbourhoods to be more walkable reported a longer time sitting at work and in public transport but a shorter sitting time in cars. Our findings suggest that walkable workplace neighbourhoods may discourage longer car use but have workplaces where workers spend a long time sitting at work. The latter finding further suggests that there may be missed opportunities for desk-based workers to reduce sitting time. Future workplace interventions to reduce sitting time may be developed, taking advantage of the opportunities to take time away from work in workplace neighbourhoods.

Associations of exposure to residential green space and neighborhood walkability with coronary atherosclerosis in Chinese adults

Residential green space and neighborhood walkability are important foundations of a healthy and sustainable city. Yet, their associations with atherosclerosis, the disease underlying clinical coronary heart disease (CHD), is unknown, especially in susceptible populations. We aim to explore the associations of exposure to residential green space and neighborhood walkability with coronary atherosclerosis. In this study of 2021 adults with suspected CHD, we evaluated the associations of exposure to green space (using Normalized Difference Vegetation Index [NDVI] and enhanced vegetation index [EVI] surrounding each participant's home) and neighborhood walkability (using walkability index and number of parks near home) with atherosclerosis (using coronary artery calcium score, CAC) using linear regression model adjusted for individual-level characteristics. Mediation analysis was further applied to explore potential mechanisms through the pathways of physical activity, air pollution, and psychological stress. In the primary model, an interquartile increase in annual mean NDVI and EVI within the 1-km area was associated with -15.8% (95%CI: 28.7%, -0.7%), and -18.6% (95%Cl: 31.3%, -3.6%) lower CAC score, respectively. However, an interquartile increase in the walkability index near home was associated with a 7.4% (95% CI: 0.1%, 15.2%) higher CAC score. The combined exposure to a green space area in a 1-km area and the walkability index were inversely associated with atherosclerosis, albeit with a smaller magnitude than a single-exposure model. The findings from a mediation analysis suggested that increased physical exercise and ameliorated particulate matter <2.5 μm (PM_2.5) may partially contribute to the relationship between green space and atherosclerosis, and for walkability index, partially explained by increased PM_2.5 exposure. Our study suggested a beneficial association between green space and atherosclerosis, but an adverse association between neighborhood walkability and atherosclerosis. Therefore, urban development that aims to improve neighborhood walkability should jointly account for enhancing green space properties from a public health perspective.

Supporting Physical Activity in Patients and Populations During Life Events and Transitions: A Scientific Statement From the American Heart Association

Achieving recommended levels of physical activity is important for optimal cardiovascular health and can help reduce cardiovascular disease risk. Emerging evidence suggests that physical activity fluctuates throughout the life course. Some life events and transitions are associated with reductions in physical activity and, potentially, increases in sedentary behavior. The aim of this scientific statement is to first provide an overview of the evidence suggesting changes in physical activity and sedentary behavior across life events and transitions. A second aim is to provide guidance for health care professionals or public health workers to identify changes and promote physical activity during life events and transitions. We offer a novel synthesis of existing data, including evidence suggesting that some subgroups are more likely to change physical activity behaviors in response to life events and transitions. We also review the evidence that sedentary behavior changes across life events and transitions. Tools for health care professionals to assess physical activity using simple questions or wearable devices are described. We provide strategies for health care professionals to express compassion as they ask about life transitions and initiate conversations about physical activity. Last, resources for life phase-specific, tailored physical activity support are included. Future research needs include a better characterization of physical activity and sedentary behavior across life events and transitions in higher-risk subgroups. Development and testing of interventions designed specifically to combat declines in physical activity or increases in sedentary behavior during life events and transitions is needed to establish or maintain healthy levels of these cardiovascular health-promoting behaviors.

Identifying and Reducing Disparities in Young Adults With Diabetes

This article outlines how social and health care determinants can affect young adults with diabetes. The authors provide a detailed description of each determinant's influence on diabetes self-management and offer solutions to help mitigate these harmful effects.

Population-Level Approaches to Preventing Type 2 Diabetes Globally

Type 2 diabetes (T2DM) is increasingly considered an epidemic rooted in modern society as much as in individual behavior. Addressing the T2DM burden thus involves a dual approach, simultaneously addressing high-risk individuals and whole populations. Within this context, this article summarizes the evidence base, in terms of effectiveness and cost-effectiveness, for population-level approaches to prevent T2DM: (1) modifications to the food environment; (2) modifications to the built environment and physical activity; and (3) programs and policies to address social and economic factors. Existing knowledge gaps are also discussed.

Global impact of physical inactivity and implications for public health nursing

Physicalinactivity has been a public health problem worldwide for more than a decade. Of those who are physically active, a substantial percentage engage solely in low or very low physical activity (PA) levels. In the last 3 decades, the prevalence of PA in the United States has decreased with approximately 80% of adults not meeting the recommended guidelines for aerobic and muscle strengthening PA. The PA levels of youth have dramatically decreased with 85% of adolescents reporting no PA. Regular PA participation can aid in preventing chronic diseases. A strong inverse dose-response relationship exists between PA and the incidence of cardiovascular disease, all-cause and cardiovascular mortality. Moreover, low cardiorespiratory fitness levels are a risk factor for cardiovascular diseases: the leading cause of death and disability globally. Conversely, high amounts of moderate-to-vigorous intensity PA at levels 3-5 times recommended in guidelines reduce risk for all cause mortality. Socio-ecological determinants of PA are essential considerations for promoting across the life course. In health care and community settings, public health nurses have opportunities to promote PA through a socio-ecological approach across the life course of individuals and diverse populations.

Understanding of Physical Activity in Social Ecological Perspective: Application of Multilevel Model

In the social ecological model, personal characteristics are important determinants of health behaviors, however, multi-dimensional approaches that consider social and physical environments must be utilized to gain a broader picture. Accordingly, this study examines the effects of personal, social, and physical environment variables as factors affecting levels of physical activity (METs). Our findings are based on 72,916 responses from the 2015 Community Health Survey in South Korea. Individual characteristics considered included sex, education level, marital status, age, and income. The social environment variables considered were trust between neighbors and the social network with neighbors. The physical environment variables were satisfaction with living environment and satisfaction with public transportation. The analysis was conducted using a multilevel model in order to accurately consider the characteristic differences of the variables. Regarding personal characteristics, sex, education level, and age have a significant effect on physical activity. Of the social and physical environment variables, social network with neighbors and satisfaction with public transportation have a significant effect on physical activity. This study confirms that a macroscopic understanding is needed to explain individual levels of physical activity; the results of this study will be helpful for public health interventions concerning physical activity.

Current Activities Centered on Healthy Living and Recommendations for the Future: A Position Statement from the HL-PIVOT Network

We continue to increase our cognizance and recognition of the importance of healthy living (HL) behaviors and HL medicine (HLM) to prevent and treat chronic disease. The continually unfolding events precipitated by the coronavirus disease 2019 (COVID-19) pandemic have further highlighted the importance of HL behaviors, as indicated by the characteristics of those who have been hospitalized and died from this viral infection. There has already been recognition that leading a healthy lifestyle, prior to the COVID-19 pandemic, may have a substantial protective effect in those who become infected with the virus. Now more than ever, HL behaviors and HLM are essential and must be promoted with a renewed vigor across the globe. In response to the rapidly evolving world since the beginning of the COVID-19 pandemic, and the clear need to change lifestyle behaviors to promote human resilience and quality of life, the HL for Pandemic Event Protection (HL-PIVOT) network was established. The 4 major areas of focus for the network are: (1) knowledge discovery and dissemination; (2) education; (3) policy; (4) implementation. This HL-PIVOT network position statement provides a current synopsis of the major focus areas of the network, including leading research in the field of HL behaviors and HLM, examples of best practices in education, policy, and implementation, and recommendations for the future.

Running prevalence in Portugal: Socio-demographic, behavioral and psychosocial characteristics

The purpose of this study was to cross-sectionally estimate the prevalence of recreational running in Portugal and describe characteristics of adult recreational runners. A random representative sample of 1068 Portuguese adults was selected. Socio-demographic information, physical activity habits and running behavior were assessed. Recreational runners’ training habits, motivations, barriers, vitality and flow were also assessed. The prevalence of recreational running in Portugal was 10.6%. It was higher in men (14.6% vs. 6.6%, p = .024) and in younger runners (13.6% vs. 7.7%, p = .026). Participants ran on average 3 times, 20 kilometers and 3 hours per week. General health orientation (88%), self-esteem (63%), and life meaning (57%) were the most predominant motives for running, while time was the most prevalent barrier (43%). This first Portuguese running prevalence representative study, indicates that almost 11% of adults ran regularly, and describes correlates of running, which can inform future running promotion interventions.

The Moderating Effect of Distance on Features of the Built Environment and Active School Transport

Despite growing research supporting the impact of the built environment on active school transport (AST), distance persists as the most powerful predictor of walking and biking to school. There is a need to better understand how environmental features interact with distance to affect AST, and whether the influence of environmental factors persist across different distance thresholds. Multilevel models using cluster-robust standard errors were used to examine for interactions between objectively measured macroscale environmental features and several reported distances from home to school (up to ¼, ¼ up to ½, ½ up to 1, 1+ miles) on the likelihood of parent reported AST for children grades 3-8 (n = 2751) at 35 schools who completed a Safe Routes to School Parent Survey about Walking and Biking to School (SRTS Parent Survey). An interaction between both intersection density and food-related land use with distance was observed. The likelihood of AST decreased as intersection density and distance increased (i.e., 31.0% reduced odds among those living within ¼ mile compared to 18.2% using ½-1-mile criterion). The likelihood of using AST were reduced as food-related land use and distance increased (i.e., 43.67% reduced odds among those living under ¼ mile compared to 19.83% reduced odds among those living ½-1 mile). Programs and infrastructure improvements focused on overcoming environmental barriers to promote AST may be most effective when targeting neighborhoods within ¼ mile of schools.

Creating Built Environments That Expand Active Transportation and Active Living Across the United States: A Policy Statement From the American Heart Association

Physical activity is vital for the health and well-being of youth and adults, although the prevalence of physical activity continues to be low. Promoting active transportation or human-powered transportation through policy, systems, and environmental change is one of the leading evidence-based strategies to increase physical activity regardless of age, income, racial/ethnic background, ability, or disability. Initiatives often require coordination across federal, state, and local agencies. To maximize the effectiveness of all types of interventions, it is imperative to establish strong and broad partnerships across professional disciplines, community members, and advocacy groups. Health organizations can play important roles in facilitating these partnerships. This policy statement provides recommendations and resources that can improve transportation systems, enhance land use design, and provide education to support policies and environments to promote active travel. The American Heart Association supports safe, equitable active transportation policies in communities across the country that incorporate consistent implementation evaluation. Ultimately, to promote large increases in active transportation, policies need to be created, enforced, and funded across multiple sectors in a coordinated and equitable fashion. Active transportation policies should operate at 3 levels: the macroscale of land use, the mesoscale of pedestrian and bicycle networks and infrastructure such as Complete Streets policies and Safe Routes to School initiatives, and the microscale of design interventions and placemaking such as building orientation and access, street furnishings, and safety and traffic calming measures. Health professionals and organizations are encouraged to become involved in advocating for active transportation policies at all levels of government.
