Legislative Health Notes: Preliminary Learnings From Piloting a New Policy Analysis Tool.

CONTEXT: In 2018, the Health Impact Project (the Project) developed and tested a new health in all policies (HiAP) tool called "legislative health notes" to provide state and local legislators with peer-reviewed evidence, public health data, and local data that illustrate potential positive and negative health and equity effects of proposed bills. OBJECTIVES: The Project sought to refine the health note methodology while piloting the tool in the Colorado and Indiana General Assemblies, and with the Council of the District of Columbia, and worked with affiliates to introduce them in North Carolina, Ohio, and California. DESIGN AND PARTICIPANTS: External partners solicited feedback on health notes via semistructured interviews and surveys from legislators, legislative staff, and expert reviewers who were familiar with health notes in each of these jurisdictions. RESULTS: Respondents shared that health notes were nonpartisan, were easy for nonexperts to understand, and would be more effective if delivered earlier in the legislative process. CONCLUSION: In response to informant feedback, practitioners can explore adding high-level summaries, increasing focus on health equity implications and the potential to work with legislators during the policy formulation phase. Data from this pilot suggest that legislative health notes are a promising nonpartisan and standardized tool to better understand the health and equity implications of proposed legislation.

The PhenX Toolkit: Recommended Measurement Protocols for Social Determinants of Health Research.

Health disparities are driven by unequal conditions in the environments in which people are born, live, learn, work, play, worship, and age, commonly termed the Social Determinants of Health (SDoH). The availability of recommended measurement protocols for SDoH will enable investigators to consistently collect data for SDoH constructs. The PhenX (consensus measures for Phenotypes and eXposures) Toolkit is a web-based catalog of recommended measurement protocols for use in research studies with human participants. Using standard protocols from the PhenX Toolkit makes it easier to compare and combine studies, potentially increasing the impact of individual studies, and aids in comparability across literature. In 2018, the National Institute on Minority Health and Health Disparities provided support for an initial expert Working Group to identify and recommend established SDoH protocols for inclusion in the PhenX Toolkit. In 2022, a second expert Working Group was convened to build on the work of the first SDoH Working Group and address gaps in the SDoH Toolkit Collections. The SDoH Collections consist of a Core Collection and Individual and Structural Specialty Collections. This article describes a Basic Protocol for using the PhenX Toolkit to select and implement SDoH measurement protocols for use in research studies. © 2024 The Authors.

TRansit ACessibility Tool (TRACT): Developing a novel scoring system for public transportation system accessibility.

Introduction: Although federal laws require equal access to public transportation for people with disabilities, access barriers persist. Lack of sharing accessibility information on public transportation websites restricts people with disabilities from making transportation plans and effectively using public transportation systems. This project aims to document information provided about public transportation systems accessibility and share this information using an open data platform. Methods: We reviewed the top twenty-six public transportation systems in the United States based on federal funding in fiscal year 2020. Information about accessibility was abstracted from each public transportation system website by two independent reviewers from February-March 2022. Informed by universal design principles, public transportation systems were scored across six dimensions: facility accessibility (0-22 points), vehicle accessibility (0-11 points), inclusive policies (0-12 points), rider accommodations (0-9 points), paratransit services (0-6 points), and website accessibility (0-2 points). Total scores were calculated as the sum of each dimension (0-62 points). Data and findings were publicly disseminated (https://disabilityhealth.jhu.edu/transitdashboard/). Results: The average overall accessibility information score was 31.9 (SD=6.2) out of 62 possible points. Mean scores were 8.4 (SD=2.9) for facility accessibility, 4.5 (SD=2.1) for vehicle accessibility, 7.8 (SD=1.6) for inclusive policies, 4.9 (SD=1.6) for rider accommodations, 4.5 (SD=2.0) for paratransit services, and 1.8 (SD=0.4) for website accessibility. Eleven public transportation systems (42%) received the maximum score for paratransit services and 20 (77%) received the maximum score for website accessibility. No public transportation system received the maximum score for any of the other dimensions. Conclusions: Using a novel scoring system, we found significant variation in the accessibility information presented on public transportation system websites. Websites are a primary mode where users obtain objective information about public transportation systems and are therefore important platforms for communication. Absence of accessibility information creates barriers for the disability community and restricts equal access to public transportation.

Inclusive and intersectoral: community health improvement planning opportunities to advance the social determinants of health and health equity.

BACKGROUND: Community health improvement plans (CHIPs) are strategic planning tools that help local communities identify and address their public health needs. Many local health departments have developed a CHIP, yet there is a lack of research on the extent to which these plans address root causes of health disparities such as the social determinants of health. This study aims to inventory the social determinants of health included in 13 CHIPs and examine facilitators and challenges faced by local health departments and partners when trying to include the social determinants of health. METHODS: We conducted a comparative plan evaluation by scoring 13 CHIPs on their inclusion of equity orientation, inclusive planning processes, and five social determinants of health: health care access and quality, the neighborhood and built environment, economic stability, social and community context, and education access and quality. To supplement the plan evaluation, we conducted 32 in-depth interviews with CHIP leaders and stakeholders to understand the factors contributing to the inclusion and exclusion of the social determinants of health in the planning process. RESULTS: CHIPs received an average score of 49/100 for the inclusion of the social determinants of health. Most plans addressed health care access and quality and the neighborhood and built environment, but they often did not address economic stability, the social and community context, and education access and quality. Regarding their overall equity orientation, CHIPs received an average score of 35/100, reflecting a relative lack of attention to equity and inclusive planning processes in the plans. Interviews revealed that challenges engaging partners, making clear connections between CHIPs and social determinants, and a lack of capacity or public and partner support often led to the exclusion of the social determinants of health. Recommendations to improve planning processes include improving data infrastructure, providing resources for dedicated planning staff and community engagement incentives, and centering equity throughout the planning process. CONCLUSIONS: Although local health departments can leverage CHIPs to improve population health and address health disparities, they face a range of challenges to including the social determinants of health in CHIPs. Additional resourcing and improved data are needed to facilitate broader inclusion of these determinants, and more work is needed to elevate equity throughout these planning processes.

Characterizing Organizational Health Equity Capacity Assessments for Public Health Organizations: A Scoping Review.

OBJECTIVE: Organizational health equity capacity assessments (OCAs) provide a valuable starting point to understand and strengthen an organization's readiness and capacity for health equity. We conducted a scoping review to identify and characterize existing OCAs. METHODS: We searched the PubMed, Embase, and Cochrane databases and practitioner websites to identify peer-reviewed and gray literature articles and tools that measure or assess health equity-related capacity in public health organizations. Seventeen OCAs met the inclusion criteria. We organized primary OCA characteristics and implementation evidence and described them thematically according to key categories. RESULTS: All identified OCAs assessed organizational readiness or capacity for health equity, and many aimed to guide health equity capacity development. The OCAs differed in regard to thematic focus, structure, and intended audience. Implementation evidence was limited. CONCLUSIONS: By providing a synthesis of OCAs, these findings can assist public health organizations in selecting and implementing OCAs to assess, strengthen, and monitor their internal organizational capacity for health equity. This synthesis also fills a knowledge gap for those who may be considering developing similar tools in the future.

Frontline work and racial disparities in social and economic pandemic stressors during the first COVID-19 surge.

OBJECTIVE: To assess the magnitude of racial-ethnic disparities in pandemic-related social stressors and examine frontline work's moderating relationship on these stressors. DATA SOURCES: Employed Californians' responses to the Institute for Governmental Studies (IGS) poll from April 16-20, 2020, were analyzed. The Pandemic Stressor Scale (PSS) assessed the extent to which respondents experienced or anticipated problems resulting from the inability to pay for basic necessities, job instability, lacking paid sick leave, unavailability of childcare, and reduced wages or work hours due to COVID-19. STUDY DESIGN: Mixed-effects generalized linear models estimated (1) racial-ethnic disparities in pandemic stressors among workers during the first COVID-19 surge, adjusting for covariates, and (2) tested the interaction between race-ethnicity and frontline worker status, which includes a subset of essential workers who must perform their job on-site, to assess differential associations of frontline work by race-ethnicity. DATA COLLECTION: The IGS poll data from employed workers (n = 4795) were linked to the 2018 Centers for Disease Control and Prevention Social Vulnerability Index at the zip code level (N = 1068). PRINCIPAL FINDINGS: The average PSS score was 37.34 (SD = 30.49). Whites had the lowest PSS score (29.88, SD = 26.52), and Latinxs had the highest (50.74, SD = 32.61). In adjusted analyses, Black frontline workers reported more pandemic-related stressors than White frontline workers (PSS = 47.73 vs. 36.96, p < 0.001). Latinxs reported more pandemic stressors irrespective of frontline worker status. However, the 5.09-point difference between Latinx frontline and non-frontline workers was not statistically different from the 4.6-point disparity between White frontline and non-frontline workers. CONCLUSION: Latinx workers and Black frontline workers disproportionately reported pandemic-related stressors. To reduce stress on frontline workers during crises, worker protections like paid sick leave, universal access to childcare, and improved job security are needed, particularly for those disproportionately affected by structural inequities, such as racially minoritized populations.

Rural Libraries as Resources and Partners for Outside Active Play Streets.

BACKGROUND: Urban and rural areas have different types of built environments and community infrastructure, which lead to different types of successful community-based physical activity initiatives. Temporary Play Streets are a supported way to increase physical activity and perceptions of the built environment as a space for active lifestyles. PURPOSE: Within the field of public health, public libraries constitute an underutilized community partner. To begin to understand the capacity of rural librarians to support rural Play Streets, a cross-sectional questionnaire was developed for distribution to rural librarians. METHODS: The sampling frame targeted members of the membership-based U.S. Association for Rural & Small Libraries (ARSL). Among respondents, 65% reported offering outdoor physical activity programs in the past, and 61% reported continuing to offer versions of this programming during the COVID-19 pandemic. Librarians work with a broad range of community partners on this programming, and already own much of the equipment necessary for a successful Play Streets initiative. CONCLUSIONS: The results of this study corroborate claims from previous research, which shows that in small and rural communities, public libraries have the capacity to play a role in promoting physical activity through involvement in community partnerships. Additional work is needed to understand, evaluate, and support this opportunity to weave rural librarians into community-based physical activity promotion efforts more fully.

Lessons from sustainability of Play Streets in the United States.

Communities around the world lack safe places for children to play and be physically active. One solution to this issue is Play Streets, which involves the temporary closure of streets for several hours to create a safe space for active play and physical activity. While the benefits of these programs are greater when they are recurring over many years, there is a dearth of literature regarding how to successfully sustain Play Streets. To understand how Play Streets can be sustained in the long term, we conducted semi-structured interviews with 24 Play Streets organizers representing 22 Play Streets programs across the United States. Four recurring sustainability challenges were highlighted from the thematic analysis: 1) securing and sustaining funding, 2) managing community and city resistance to street closures, 3) navigating government bureaucracy, and 4) retaining interest amongst organizers and volunteers. With each challenge, we describe how Play Streets organizers navigated those challenges, with a goal of generating recommendations for those wishing to sustain Play Streets programs in the long term.

Structural Racism, Place, and COVID-19: A Narrative Review Describing How We Prepare for an Endemic COVID-19 Future.

Background: Place is a social determinant of health, as recently evidenced by COVID-19. Previous literature surrounding health disparities in the United States often fails to acknowledge the role of structural racism on place-based health disparities for historically marginalized communities (i.e., Black and African American communities, Hispanic/Latinx communities, Indigenous communities [i.e., First Nations, Native American, Alaskan Native, and Native Hawaiian], and Pacific Islanders). This narrative review summarizes the intersection between structural racism and place as contributors to COVID-19 health disparities. Methods: This narrative review accounts for the unique place-based health care experiences influenced by structural racism, including health systems and services and physical environment. We searched online databases for peer-reviewed and governmental sources, published in English between 2000 and 2021, related to place-based U.S. health inequities in historically marginalized communities. We then narrate the link between the historical trajectory of structural racism and current COVID-19 health outcomes for historically marginalized communities. Results: Structural racism has infrequently been named as a contributor to place as a social determinant of health. This narrative review details how place is intricately intertwined with the results of structural racism, focusing on one's access to health systems and services and physical environment, including the outdoor air and drinking water. The role of place, health disparities, and structural racism has been starkly displayed during the COVID-19 pandemic, where historically marginalized communities have been subject to greater rates of COVID-19 incidence and mortality. Conclusion: As COVID-19 becomes endemic, it is crucial to understand how place-based inequities and structural racism contributed to the COVID-19 racial disparities in incidence and mortality. Addressing structurally racist place-based health inequities through anti-racist policy strategies is one way to move the United States toward achieving health equity.

Association Between Fatal Occupational Injuries and State Minimum-Wage Laws, 2003-2017.

INTRODUCTION: Low wages are associated with an increased risk of occupational injuries. Increasing the minimum wage is one way to increase workers' wages; however, a previous study found that higher state minimum wage was associated with an increase in nonfatal occupational injuries and illnesses. This study aims to examine the association between state minimum-wage laws and fatal occupational injuries. METHODS: Fatal occupational injury data (2003-2017) for the 50 U.S. states were obtained from the Census of Fatal Occupational Injuries. State minimum-wage law information was obtained from Temple's LawAtlas website. Linear and Poisson regression models were used to analyze the association between state minimum-wage laws and the rates of fatal occupational injury per 100,000 workers. All data were analyzed in 2020. RESULTS: Having a state minimum wage higher than the federal minimum had no statistically significant association with fatal occupational injury rate, (-4.0%, 95% CI= -9.1, 1.5). State minimum wage amount was also not associated with fatal occupational injuries (-4.0%, 95% CI= -9.1, 1.5). CONCLUSIONS: Although previous research suggested that state minimum-wage laws were associated with increased rates of nonfatal occupational injuries, these findings indicate that these laws are not associated with an increased risk of fatal occupational injuries. Concerns that raising the minimum wage will lead to worse workplace safety may be unfounded.

Systematic review on quantifying pedestrian injury when evaluating changes to the built environment.

Modifying the built environment to make communities more walkable remains one strategy to promote physical activity. These modifications may have the added benefit of reducing the risk of pedestrian injury; however, there is a gap in the physical activity literature regarding how best to measure pedestrian injury. Examining the measures that have been used and related data sources can help inform the use of pedestrian injury data to evaluate whether safety is optimized as walking increases. We conducted a systematic review of the literature to identify studies that evaluated changes to the built environment that support walking and measures impacts on pedestrian injury as a measure of safety. We searched PubMed, PsycInfo, and Web of Science to identify peer-review studies and websites of fifteen organizations to document studies from the grey literature published in English between January 1, 2010 and December 31, 2018. Our search identified twelve studies that met the inclusion criteria. The few studies that measured changes in pedestrian injury used crash data from police reports. Injury frequency was often reported, but not injury severity, and no studies reported injury risk based on walking exposure. We conclude that few studies have measured pedestrian injury in the context of creating more walkable communities. Future research would benefit from using well-characterized measures from existing studies to support consistency in measurement, and from more longitudinal and evaluation research to strengthen the evidence on additional benefits of walkability. Increased collaborations with injury prevention professionals could bolster use of valid and reliable measures.

State and Local Healthy Kids' Meal Laws in the United States: A Review and Content Analysis.

BACKGROUND: To address unhealthy restaurant food intake among children, localities and states are passing healthy restaurant kids' meal laws. However, there is limited knowledge of what these policies require and how they compare with expert and industry nutrition standards. OBJECTIVES: The aim of this study was to develop a research instrument to evaluate healthy kids' meal laws and assess their alignment with expert and industry nutrition standards. DESIGN: The study team conducted a content analysis of healthy kids' meal laws passed between January 2010 and August 2020 in the United States. Using a structured codebook, two researchers abstracted policy elements and implementation language from laws, regulations, fiscal notes, and policy notes. Nutritional criteria for kids' beverages and meals were compared with existing expert and industry nutrition standards for meals and beverages. MAIN OUTCOME MEASURES: Measures included law characteristics, implementation characteristics, enforcement characteristics, definitions of key terms, and nutritional requirements for meals and default beverage options and alignment with expert and industry nutrition standards. STATISTICAL ANALYSES PERFORMED: Interrater reliability of the coding tool was estimated using the Cohen kappa statistic, and researchers calculated descriptive statistics of policy elements. RESULTS: Twenty laws were identified. Eighteen were healthy default beverage policies, two were toy restriction policies, and one was a nutrition standards policy. The nutrition standards, default beverage offerings, and implementation characteristics varied by location. No law met the expert nutrition standards for kids' meals or beverages. CONCLUSIONS: The variations in policy specifications may influence how restaurants implement the policies, and, consequently, the policies' influences on children's consumption. Future policies could use expert nutrition standards to inform the standards set for kids' meals and specify supports for implementation.

Factors Associated with Universal Free School Meal Provision Adoption among US Public Schools.

BACKGROUND: The Community Eligibility Provision (CEP) allows high-poverty schools participating in US Department of Agriculture meal programs to offer universal free school meals. Emerging evidence suggests benefits of CEP for student meal participation, behavior, and academic performance. Although CEP became available nationwide in 2014, in school year 2019-2020, one third of eligible schools were not participating. OBJECTIVE: This study evaluates which school, district, and state factors are associated with CEP participation. DESIGN: Cross-sectional study comparing CEP-participating with eligible nonparticipating schools to assess the relationship between CEP participation and school, district, and state factors. PARTICIPANTS: US public schools eligible for CEP in school year 2017-2018 (n = 42,813). MAIN OUTCOME MEASURES: CEP participation. STATISTICAL ANALYSES PERFORMED: Penalized regression variable selection methods to determine which factors contribute information to the model. Generalized logistic regression to predict odds of CEP participation unadjusted and adjusted for each factor in the full sample and in stratified analyses by whether a state was part of the CEP phase-in period (early vs late implementing states). RESULTS: In the full sample, adjusted odds of CEP participation were greater in states where CEP had been available longer (odds ratio [OR], 1.50; 95% confidence interval [CI], 1.34, 1.67). In late implementing states, adjusted odds of CEP participation were higher in schools with more students directly certified for free meals (OR in schools with 80%-89% vs 30%-39% directly certified: 19.32; 95% CI, 12.98, 28.76), Title I schools (OR, 1.85; 95% CI, 1.55, 2.21), and urban schools (OR suburban vs urban, 0.46; 95% CI, 0.36, 0.59). Differences by school level, enrollment, district size, student race/ethnicity, and geographic region also existed. CONCLUSIONS: Findings may help advocates, state agencies, and policymakers understand potential barriers to adoption and guide research exploring effective strategies to promote uptake. Future research should use qualitative and longitudinal designs to explore barriers to adoption, including cost and state and local policies.

Implementing Play Streets in Low-Income Rural Communities in the United States.

Play streets involve the temporary closure of streets that for a specified time create a safe place for active play. Play streets have been implemented primarily in cities; it is unknown if they could be adapted and implemented in rural areas. To learn about implementation, core components of play streets and inform adaptation, we conducted systematic peer-reviewed and grey literature searches and interviews with a purposive sample of key informants. Data were analyzed by theme and used to inform implementation of play streets by four community organizations in low-income rural areas of Maryland, North Carolina, Oklahoma, and Texas from June to September 2017. Core elements of play streets in urban areas were present in rural settings-the content (e.g., activities offered), delivery of the intervention in partnership with community members and local organizations, and reoccurrence of play streets at a single location. There were three key adaptations relating to delivery and context to consider uniquely when implementing play streets in rural areas (1) using locations other than streets, (2) varying locations to account for geographic dispersion, and (3) maximizing participation and resources by coupling play streets with community events. Play streets can be successfully implemented in rural settings with these modifications, which support feasibility, reach, and access. Play streets in rural areas should include activities for active play that are age-appropriate and fun, without necessarily tailoring content for rural areas.

Real-Time Video Scan Method for Community Partner Use to Inform Play Streets Implementation.

System for Observing Play and Recreation in Communities (SOPARC) can provide accurate assessment of physical activity; however, the skills, time, and human resources necessary to collect/interpret SOPARC data can be challenging for community organizations. This article describes a more accessible adaptation of SOPARC using video recordings for community organizations to obtain physical activity feedback at Play Streets. Narrated panoramic video scans occurred every 30 minutes at each Play Street using an iPad. Videographers narrated: (1) sex, (2) age group (child, teen, adult, senior), and (3) activity level (sedentary, walking, vigorous) for everyone recorded. SOPARC video scans, in-person iSOPARC observations, and interviews were conducted with Play Streets implementors to determine validity and feasibility. Validity was examined using Lin's concordance correlation coefficient (CCC). In-person and video scans showed near perfect agreement for sedentary individuals (CCC = .95) and substantial agreement for active individuals (CCC = .72). Overall, community partners felt that they "could see how [the scans] could be useful" and "help[ed] see a bit more clearly what's happening." The method described here is a more accessible systematic observation approach to measure physical activity for communities implementing Play Streets. Further, this method can be used without research training while still providing valuable activity feedback.

The Effects of Play Streets on Social and Community Connectedness in Rural Communities.

Promoting physical activity (PA) is a long-standing public health initiative to improve overall health and wellbeing. Innovative strategies such as Play Streets, temporary activation of public spaces to provide safe places for active play, are being adopted in urban and rural communities to increase PA among children. As part of these strategies, aspects of social and community connectedness may be strengthened. This study analyzes focus groups and interviews from rural Play Street implementation team members (n = 14) as well as adults (n = 7) and children (n = 25) who attended Play Streets hosted in rural North Carolina, Maryland, Oklahoma, and Texas to better understand the added benefits of Play Streets in community connectedness. Overall, elements of social support and social cohesion are mentioned most frequently with instrumental and conditional support; however, concepts of social capital, collective-efficacy, and social identification are also presented. Participants expressed that Play Streets provided more than just PA; they provided opportunities to access and share resources, build perceptions of safety and trust in the community, and develop relationships with others. Fostering community connection through Play Streets may reduce health inequities in rural communities by building community resilience. Community-based PA programming that enhance and capitalize on community connectedness could be effective ways to improving the overall health and wellbeing of residents.

A Social-Return-On-Investment Analysis Of Bon Secours Hospital's 'Housing For Health' Affordable Housing Program.

Community health programs aimed at addressing the social determinants of health often face challenges demonstrating their impact through traditional economic evaluation methods of return-on-investment analysis, cost-effectiveness analysis, or cost-benefit analysis. Using a social-return-on-investment (SROI) analysis, we evaluated the broader social, environmental, and economic benefits of Bon Secours Hospital's Housing for Health program, an affordable housing program aimed at addressing the social and environmental determinants affecting its community's health in Baltimore, Maryland. Bon Secours currently has 801 units of affordable housing across twelve properties in West Baltimore. Results indicate the significant social value of the Bon Secours affordable housing program, generating between $1.30 and $1.92 of social return in the community for every dollar in yearly operating costs. These findings suggest that broader access to affordable housing could produce a positive social value and demonstrate the relevance of SROI for quantifying the impacts of community health programs.

Examining Batting Performance After a Sports-Related Concussion Among Major League Baseball Position Players.

BACKGROUND: An ongoing challenge in sports-related concussion (SRC) is determining full recovery. This study examines performance metrics in baseball after an SRC and provides a template for assessment of return-to-performance parameters. PURPOSE: To determine whether batting performance returns to baseline after an SRC. STUDY DESIGN: Descriptive epidemiological study. METHODS: Participants were all Major League Baseball (MLB) position players with confirmed SRCs that occurred during the 2011-2015 seasons. A retrospective review and assessment of performance metrics before and after injury were conducted as defined relative to the number of plate appearances (PAs) to yield reliable performance statistics. Seven batting metrics were considered as outcomes in longitudinal regressions: batting average, on-base percentage, slugging percentage, on-base plus slugging, bases on balls, strikeouts, and home runs. Metrics were calculated for each player 60, 30, and 14 days before their SRCs, as well as for the 14, 30, and 60 days after returning to play. Other variables controlled for included defensive position, player age at the time of SRC, number of days missed, mechanism of injury, whether the player completed a rehabilitation stint, and year in which the mild traumatic brain injury (MTBI) occurred (2011-2015). RESULTS: A total of 77 MTBI case events occurred in MLB position players over 5 seasons. These injuries resulted in a mean 11.4 days lost to injury. For all performance metrics using 60 or 30 days before MTBI as baseline, no statistically significant differences were found in batting performance. In total, 63 events met PA criteria before injury. Varying the PA cutoff thresholds to be more inclusive or more restrictive yielded similar regression results. For the 48 events that met PA criteria before and after injury, most performance metrics showed no significant performance change after MTBI and, in some events, a slight though mostly nonsignificant performance improvement after MTBI. CONCLUSIONS: MLB position players who are medically cleared to return to play after an SRC perform at the same offensive performance levels as their preinjury statistics when an adequate number of PAs is used to compare performance before and after injury.
