Modifying effect of urban parks on socioeconomic inequalities in diabetes prevalence: a cross-sectional population study of Madrid City, Spain.

BACKGROUND: Evidence has shown contradicting results on how the density of urban green spaces may reduce socioeconomic inequalities in type 2 diabetes (equigenic hypothesis). The aim of this study is to test whether socioeconomic inequalities in diabetes prevalence are modified by park density. METHODS: We designed a population-wide cross-sectional study of all adults registered in the primary healthcare centres in the city of Madrid, Spain (n=1 305 050). We obtained georeferenced individual-level data from the Primary Care Electronic Health Records, and census-tract level data on socioeconomic status (SES) and park density. We modelled diabetes prevalence using robust Poisson regression models adjusted by age, country of origin, population density and including an interaction term with park density, stratified by gender. We used this model to estimate the Relative Index of Inequality (RII) at different park density levels. FINDINGS: We found an overall RII of 2.90 (95% CI 2.78 to 3.02) and 4.50 (95% CI 4.28 to 4.74) in men and women, respectively, meaning that the prevalence of diabetes was three to four and a half times higher in low SES compared with high SES areas. These inequalities were wider in areas with higher park density for both men and women, with a significant interaction only for women (p=0.008). INTERPRETATION: We found an inverse association between SES and diabetes prevalence in both men and women, with wider inequalities in areas with more parks. Future works should study the mechanisms of these findings, to facilitate the understanding of contextual factors that may mitigate diabetes inequalities.

Investigating the Relationship Between Accessibility of Green Space and Adult Obesity Rates: A Secondary Data Analysis in the United States.

OBJECTIVES: In spite of the importance of green space for reducing obesity-related problems, there has been little exploration of whether access to green space (e.g., parks and recreational facilities) influences the obesity rate of adults in the United States. The purpose of the study was to investigate the relationships among accessibility of green space, obesity rates, and socioeconomic and demographic variables among adults living in the State of Indiana, United States. METHODS: We conducted a secondary data analysis to investigate the relationships among accessibility to green space, obesity rates, and socio-demographic variables with employing Geographic Information System in order to measure the accessibility of green space. RESULTS: This study found that accessibility of green space served as a strong predictor of reduced obesity rates among adults (ß=-2.478; p<0.10). In addition, adults with higher education levels, as well as better access to green space, were found to have even lower obesity rates (ß=-0.188; p<0.05). Other control variables such as unemployment rates, food security, and physical inactivity are additional factors that influence obesity rates among adults. CONCLUSIONS: Accessibility of green space may play an important role in facilitating physical activity participation and reducing obesity rates.

Psychographic variables, tourist behaviour and vandalism in the South-East Asian tourism sector.

This study examines multi-stakeholders' perceptions of vandalism at tourist attractions in two Asian cities: Bangkok and Singapore. It provides an opportunity to explore the differences and similarities in stakeholder attitudes towards attraction management and reveals desired levels of participation of community in managing vandalism in tourism. This mixed method research employs community survey and interviews of site managers and government officials as its main data collection approach. It also offers an innovative approach to data analysis using the severity and optimist/pessimist psychographic variables coupled with quantitative analytical techniques. The results reveal complex relationship between psychographic profiles, future and current time dimensions, and location. In conclusion, the study offers several recommendations to city managers and policymakers on methods of vandalism control. It also highlights the importance of cultural context and its influence on community involvement. While this study is limited to tourism attractions, it provides a solid foundation for future research, one that can extend into urban planning and public policy design.

Assessment of losses to the local population due to restrictions on their ownership rights to land and property assets: The case of the Tunkinsky National Park, Russia.

The impact of protected areas on local communities is the subject of intense discussions as part of the implementation of the global ecosystem protection agenda. Conflicts between the interests of environmental protection and the needs of socio-economic development become particularly acute when large areas of land are taken out of economic circulation as a result of organizing protected areas. In this case, there is an urgent need for detailed and reliable information about the social impacts of such land withdrawal on the well-being of the local population. An analysis of the methodological approaches widely presented in the literature, used to assess the social impact of protected areas, testifies to the insufficiency of completed and practically applicable methodological guidelines for the areas with significant restrictions for people who form part of the protected landscape. In this study, we understand the cost estimate of the social impact of national parks on the local population as a quantitative calculation of the losses due to restrictions on their ownership rights to land and property assets. The methodological approach consists in considering the category of losses as a sum total of the actual damage and lost profits. The assessment algorithm includes three stages: systematization of social impacts on citizens, development of indicators and data collection, and calculation of actual damage to the population and lost profits. The assessment is performed using the example of the Tunkinsky National Park located in the Tunkinsky municipal district of the Republic of Buryatia, a region of the Russian Federation, where there are 14 rural settlements with a population of more than 20,000 people. The results of the calculations show that the losses of the rural population due to legal restrictions on the registration of land dealings amount to 170.4 million USD. Taking into account the potential amount of administrative fines and the value of property subject to demolition, the losses amount to 239.2 million USD. It is more than an order of magnitude greater than the amount of own revenues of the Tunkinsky municipal district in 2011-2019. The results obtained demonstrate the real picture of the impact of restrictions on the rights of local people to land within the boundaries of national parks and are useful for developing measures to account for their interests and include protected areas in the socio-economic development of regions. The methodological approach developed by the authors can be used in other national parks, where it is necessary to optimize the policy of improving land use for local residents.

The Impact of Schoolyard Greening on Children's Physical Activity and Socioemotional Health: A Systematic Review of Experimental Studies.

Access to green schoolyards (schoolyards designed with greenery and natural elements to create a park-like environment, as opposed to asphalt-based playgrounds) are associated with many benefits for students, including improvements in physical and mental health. While many studies examining these associations are cross-sectional, some feature experimental designs that offer the possibility of causal inference. In this review, we looked at experimental studies that examine the impact of schoolyard greening on measures of physical activity and socioemotional health in children. Four electronic databases (Ovid Medline, PsycINFO, Scopus and Greenfile) were searched, and from 1843 articles retrieved, 6 articles met the inclusion criteria. Examination of the eligible studies revealed a general consensus on the positive impact of schoolyard greening on both physical activity and socioemotional health outcomes for students, suggesting that schoolyard greening is a viable intervention in reducing the health equity gaps and improving children's health regardless of their racial or ethnic backgrounds or residential neighborhood socioeconomic status. Further experimental research on this topic should elucidate how educators, administrators, policy makers, and other stakeholders can harness the benefits of schoolyard greening to improve the health and well-being of children in their communities.

A call to action: Improving urban green spaces to reduce health inequalities exacerbated by COVID-19.

Health is not equally distributed across society; there are avoidable, unfair, systematic differences in health between population groups. Some of these same groups (older people, BAME communities, those with some non-communicable diseases (NCDs)) may be particularly vulnerable to risk of exposure and severe COVID-19 outcomes due to co-morbidities, structural vulnerabilities, and public-facing or health and social care jobs among other factors. Additionally, some of the restrictions designed to reduce SARS-CoV-2 spread impact specifically on these same groups by limiting their activity and access to preventive or health promotion services. Greenspaces, accessed with social distancing, may mitigate some of the predicted negative health effects of COVID-19 restrictions. Maintaining or increasing publicly accessible urban greenspaces, particularly for marginalised groups, is reflected in the Sustainable Development Goals, and its importance amplified in the COVID-19 pandemic. Urban greenspaces should be considered a public health and social investment and a chance to rebalance our relationship with nature to protect against future pandemics. By investing in urban public greenspaces, additional benefits (job/food creation, biodiversity promotion, carbon sequestration) may coincide with health benefits. Realising these requires a shift in the balance of decision making to place weight on protecting, enhancing and providing more appropriate greenspaces designed with local communities. The current pandemic is a reminder that humanity placing too many pressures on nature has damaging consequences. COVID-19 economic recovery programs present an opportunity for sustainable transformation if they can be leveraged to simultaneously protect and restore nature and tackle climate change and health inequalities.

Equity to Urban Parks for Elderly Residents: Perspectives of Balance between Supply and Demand.

As population ages, ensuring that the elderly get their due rights has become a common concern of scholars in many fields. However, as an important public service facility in daily life of elderly, the research on the equity of urban parks is mostly based on the evaluation of accessibility. The equity of the elderly's access to urban parks services has been rarely discussed from the perspective of supply and demand balance. In the context of the concept of spatial equity, we used urban parks in the main city of Harbin as a case study, the actual travel mode of the elderly was considered in the evaluation, adopted an Integrated Spatial Equity Evaluation (ISEE) framework, quantitative evaluation of the equity of different levels of urban park under multiple traffic modes. In this study, the results showed that under the three modes of travel, the degree of spatial equity was higher for non-motorized trips than for the other two modes. In terms of urban parks hierarchy, the spatial equity of urban parks at district level were much higher than those at the neighborhood level and street level. The inequity between supply and demand for urban park for elderly people was significant and varies between administrative districts. The empirical evidence in this research may provide references and suggestions for urban parks planning and decision-making. In cities where the scale of land use is basically stable, such as Harbin, we can start from the spatial configuration of park green space system and public transportation system to improve the efficiency of urban parks provision. Thereby promoting the construction and development of an "old age-friendly" society.

Inequities in neighborhood public park use for schoolchildren's physical activity: multilevel evidence from Cordoba, Argentina.

INTRODUCTION: The complexity of urbanization processes across Latin American societies encourages investigating its implications in health conditions, especially during childhood. One of the possible links between them is recreation, a component of the daily life of children and, therefore, essential to produce health and life itself. The objective of this study was to examine the associations between neighborhood context and active public park use among school-aged children in Cordoba, Argentina. METHODS: A cross-sectional study was conducted with 1466 children, aged 9 to 11, attending 19 schools and living in 110 neighborhoods. Multilevel models with Poisson distribution were used for the analyses, stratified by gender. Socio-demographic, behavioral, and physical covariates were included at the individual level, and socioeconomic neighborhood conditions at second level. RESULTS: Girls residing in neighborhoods with a worse socioeconomic context were less likely to report frequent public park use for physical activity, while those from neighborhoods with better socioeconomic conditions were more likely to, regardless of individual characteristics. CONCLUSION: This study suggests that socioeconomic conditions of neighborhoods are associated with public park use for physical activity in school-aged girls, demonstrating gender inequality in the use and appropriation of public spaces.

Understanding the contribution of public- and restricted-access places to overall and domain-specific physical activity among Mexican adults: A cross-sectional study.

Latin Americans engage in physical activity (PA) in unique ways and use a wider range of places for PA than those commonly studied in high-income settings. We examined the contribution of a variety of places and domains of PA to meeting PA recommendations among a sample of adults (18-65 y) from all over Mexico. This was a cross-sectional study conducted in 2017 (n = 3 686). Overall and domain-specific PA was measured using the Global Physical Activity Questionnaire. Use of places for PA was self-reported. Places were classified as private or public. In 2018, associations between specific places and meeting PA recommendations (≥150 mins/week) were estimated using multivariate logistic regression models. In total 72.1% met PA recommendations. The proportion meeting recommendations through domain-specific PA was highest for leisure-time PA (50.0%), followed by travel-related (39.1%) and work-related (24.9%) PA. The most commonly reported places for PA were home (43%), parks (40.7%) and streets (39.4%) (public). Use of most public places was positively associated with meeting PA recommendations, mainly through travel-related PA (Streets OR 2.05 [95% CI 1.71-2.45]; Cycling paths OR 1.91 [1.37-2.68]). Using private places was more strongly associated with PA, mainly leisure-time PA (Gyms OR 9.66 [7.34-12.70]); Sports facilities OR 5.03 [3.27-7.74]). In conclusion, public and private places were important contributors to PA. While public places may be a powerful setting for PA promotion, increasing the equitable access for all to private places may also represent an effective strategy to increase PA among Mexican adults.

Improved Street Walkability, Incivilities, and Esthetics Are Associated with Greater Park Use in Two Low-Income Neighborhoods.

Parks may provide opportunities for people to increase their physical activity and improve health. Yet, parks are generally less plentiful and underutilized in low-income urban neighborhoods compared with more advantaged neighborhoods. Renovations within and around parks may improve park utilization but the empirical evidence supporting this relationship is scarce. This study assessed the impact of greenspace, housing, and commercial investments on street characteristics (walkability, amenities, incivilities/poor esthetics) and park use by examining park use over time in two low-income neighborhoods in Pittsburgh, PA (n = 17 parks), before and after neighborhood-based renovations that were primarily centered in one neighborhood. We used systematic observation of parks, park use, and street blocks surrounding parks to examine the impact of neighborhood changes on park use. We used difference-in-differences to test whether park use and street characteristics surrounding the parks improved more in the intervention neighborhood than in the comparison neighborhood. We also used zero-inflated negative binomial regression with interactions by time to test whether changes in street characteristics were associated with changes in park use over time. We found that improved walkability, incivilities, and esthetics surrounding parks in socioeconomically disadvantaged neighborhoods were associated with greater park use and may help increase visits to underutilized parks.

Is the availability of open public spaces associated with leisure-time physical activity in Brazilian adults?

This study aims to analyse the association between perceived presence of public spaces near residences and practice of physical activity during leisure time by adults in the state capitals of Brazil, based on sociodemographic characteristics. Participants were individuals aged ≥18 years living in the 27 state capitals of Brazil (n = 52 929, 53.9% female) who responded to a national survey called VIGITEL in 2013. Physical activity during leisure time (≥1 time/week), perception of space, population and sociodemographic variables (sex, age, years of study and geographic region) were self-reported. The adjusted binary logistic regression analysis was used. Among adults, the prevalence of physical activity during leisure was 45.1% (95% CI [44.2; 46.0]), and 71.1% (95% CI [70.2, 71.8]) perceived public space near their residence. A direct association between perceiving public space and physical activity ([OR] = 1.43; 95% CI [1.32; 1.55]) was observed. No significant difference was observed in the population groups (men and women, younger and older adults, and those with more and fewer years of study). Thus, even with the possible regional differences in Brazilian state capitals, the presence of public spaces increases the practice of physical activity during leisure time, independent of sociodemographic variables.

Neighborhood characteristics associated with park use and park-based physical activity among children in low-income diverse neighborhoods in New York City.

Urban parks provide spaces and facilities for children's physical activity (PA) and can be a free resource in low-income communities. This study examined whether neighborhood characteristics were associated with children's park use and park-based moderate-to-vigorous PA (MVPA) in low-income diverse communities and how associations differed between ethnic groups. Data on park visits and MVPA came from 16,402 children 5-10-years old directly observed using the System for Observing Play and Recreation in Communities in 20 parks in low-income neighborhoods with majority Latino or Asian populations in New York City. Neighborhood characteristics included land use mix (LUM), street audits, crime rates, and an area deprivation index. We employed Poisson and negative binomial models to estimate effects of neighborhood-level variables on the number of children observed in parks and engaging in MVPA, overall and by ethnicity. Results for Asian, Latino, and African American children indicated that higher levels of LUM and pedestrian-friendly streets were associated with greater numbers of children in parks and higher MVPA across all three groups. For Asian and Latino children only, quality of environment was positively associated with MVPA, whereas level of deprivation and crime rates in the surrounding neighborhood were negatively associated with children's park-based MVPA. In contrast, a park's access to public transportation was negatively associated with number of all children observed and engaging in MVPA. Study findings suggest that park-based MVPA interventions can be informed by understanding how neighborhood characteristics facilitate and constrain park use and park-based MVPA.

Inequities in neighborhood public park use for schoolchildren's physical activity: multilevel evidence from Cordoba, Argentina / Desigualdades no uso do parque público de bairro para a atividade física de crianças: evidências multiníveis de Córdoba, Argentina

RESUMO: Introdução: O processo de urbanização das sociedades latino-americanas estimula investigar suas consequências nas condições de saúde. Um dos elos possíveis é a recreação, componente do cotidiano das crianças essencial para a produção da saúde e da própria vida. O objetivo foi examinar as relações entre o contexto do bairro e o uso ativo do parque público entre as crianças em idade escolar em Córdoba, Argentina. Métodos: Foi realizado um estudo transversal com 1466 crianças que frequentam 19 escolas e moram em 110 bairros. Modelos multinível com distribuição de Poisson foram utilizados para as análises, estratificados por sexo. Covariáveis sociodemográficas, comportamentais e físicas foram incluídas no nível individual e as condições socioeconômicas do bairro, no segundo nível. Resultados: As meninas que residem em bairros com pior contexto socioeconômico foram menos prováveis a relatar o uso frequente de parques públicos para atividades físicas, enquanto aquelas provenientes de bairros com melhores condições eram mais prováveis, independentemente das características individuais. Conclusões: Este estudo sugere que as condições socioeconômicas dos bairros estão associadas ao uso de parques públicos para atividade física em meninas unicamente, demonstrando uma desigualdade de gênero.

A systematic review of multi-dimensional quality assessment tools for urban green spaces.

We conducted a systematic review of quality assessment tools for urban green spaces to evaluate their replicability, comparability and validity. We assessed the characteristics of 15 published, multi-dimensional, direct observation tools regarding: publication, development, features and included dimensions. Even though all tools show acceptable inter-rater variability, there is a notable variability in their characteristics, from required time to conduct the assessment to the number of included items. Additionally, some specific dimensions are underrepresented, and the study units' definitions are feeble. We showcased the need for new tools that are more comprehensive and include more consistent reporting measures.

Inequalities in Exposure to Nitrogen Dioxide in Parks and Playgrounds in Greater London.

Elevated levels of nitrogen dioxide (NO2) have been associated with adverse health outcomes in children, including reduced lung function and increased rates of asthma. Many parts of London continue to exceed the annual average NO2 concentration of 40 µg/m3 set by the EU directive. Using high-resolution maps of annual average NO2 for 2016 from the London Atmospheric Emissions Inventory and detailed maps of open spaces from Britain's national mapping agency, Ordnance Survey, we estimated average NO2 concentrations for every open space in Greater London and analysed geospatial patterns comparing Inner verses Outer London and the 32 London Boroughs. Across Greater London, 24% of play spaces, 67% of private parks and 27% of public parks had average levels of NO2 that exceeded the EU limit for NO2. Rates of exceedance were higher in Inner London; open spaces in the City of London had the highest average NO2 values among all the London Boroughs. The closest play space for more than 250,000 children (14% of children) under 16 years old in Greater London had NO2 concentrations above the recommended levels. Of these children, 66% (~165,000 children) lived in the most deprived areas of London, as measured by the Index of Multiple Deprivations, where average NO2 concentrations in play spaces were on average 6 µg/m3 higher than for play spaces in the least deprived quintile. More action is needed to reduce NO2 in open spaces to safe levels through pollution reduction and mitigation efforts, as currently, open spaces in Greater London, including play spaces, parks and gardens, still have dangerously high levels of NO2, according to the most recent NO2 map.

Levels and human health risk assessment of heavy metals in surface soil of public parks in Southern Ghana.

This study evaluates the extent to which humans may be exposed to health risk from heavy metals in surface soils of public parks in Southern Ghana during outdoor activities. The study investigated surface soils of 56 public parks from seven metropolitan cities in Southern Ghana. Heavy metals (Cd, Cr, Cu, Hg, Mn, Ni, Pb, and Zn) were determined using microwave-assisted HNO3-HF acid digestion and atomic absorption spectroscopy with flame, graphite furnace, and cold vapor options. All parks studied registered the presence of heavy metals with mean concentrations following the order: Mn > Zn > Cr > Pb > Cu > Ni > Cd > Hg. Whereas the mean concentrations of Zn (221.92 mg/kg) and Cr (107.01 mg/kg) respectively exceeded the Canadian (200 mg/kg; 64 mg/kg) and the EU (100-200 mg/kg; 50-100 mg/kg) standards, the ranges of Cu (14.27-138.85 mg/kg) and Pb (6.46-628.31 mg/kg) also exceeded their EU range of 50-100 mg/kg. The results indicated that there was no immediate risk to Ni and Hg on the public parks studied; however, Pb, Cd, Zn, Cu, and Cr may pose some adverse effects as they exceed their respective guideline limits in soil. The ranges of non-carcinogenic risk for adults and children were 0.0186-0.0787 and 0.0197-0.0850 respectively while the corresponding ranges for carcinogenic risks were 3.75 × 10-7-1.28 × 10-6 and 4.17 × 10-7-1.31 × 10-6. Even though risk assessment suggested low and acceptable health risk levels to patrons, there is the need for close monitoring since Pb, Cd, Zn, Cu, and Cr have shown tendency of accumulating beyond acceptable limit.

Identification and assessment of the driving forces for the use of urban green parks and their accessibility in Colombo, Sri Lanka, through analytical hierarchical processing.

Urban green parks perform a remarkable role for the physical, social and psychological wellbeing of the urban public by providing space for relaxation and recreation, directly influencing public health through mitigation of the urban heat impact, noise reduction and moderation of air and water pollution. An indicator-based approach on analytical hierarchical processing was used to identify and assess the driving forces for the utilization of urban green parks and their accessibility. Eight indicators: location, topography and geography, facility and services, safety and security, social and culture, ecology, demography, and weather and climate (further divided into 50 factors) were used in the study. Data were collected through a questionnaire survey in which 887 regular park users participated. A standardized study design was implemented to study and assess four urban green parks in the Colombo metropolitan district, Sri Lanka. The study identified park facilities and services as well as safety and security measures maintained by the park as the key factors of appeal, while location, ecology, topography and geography, including weather and climate, had a lower relative influence when selecting a park for recreation. Social, cultural and demographic factors appeared to be of the least interest. The study recommends park managers to assess their parks using this model to enhance the characteristics found to be the most important. It further suggests developing models also for other park types by considering which factors would have the highest relative influence in providing a better service for the regular park user.

Association Between Neighborhood Income, Patterns of Use, and Physical Activity Levels in Fitness Zones of Curitiba, Brazil.

Background: Socioeconomic characteristics of locations where physical activity equipment is installed may affect the activity level of users. The purpose of this study was to verify patterns of use and physical activity levels in fitness zones installed in low- and high-income neighborhoods in the city of Curitiba, Brazil. Methods: Over 1200 observations were conducted in 20 fitness zones in the city of Curitiba, Brazil. Data were collected during the months of November and December 2012, in 4 periods of the day (8 AM, 11 AM, 2 PM, and 5 PM), on 2 weekdays and 2 weekend days. Results: A total of 2232 people were observed in the fitness zones. Age group, level of physical activity in the area, use of fitness zones during weekend days, and occupation of spaces were significantly associated with neighborhood income. Moreover, users of fitness zones located in high-income neighborhoods showed higher odds ratio (OR = 1.74; 95% confidence interval, 1.46-2.07) of moderate to vigorous physical activity than light or sedentary activities, regardless of gender or day of the week. Conclusions: The sole presence of equipment does not seem to favor the use of fitness zones in low-income neighborhoods. Future studies should investigate intrinsic factors for the use of fitness zones for physical activity.

Residential neighborhood greenery and children's cognitive development.

Children who grow up in neighborhoods with more green vegetation show enhanced cognitive development in specific domains over short timespans. However, it is unknown if neighborhood greenery per se is uniquely predictive of children's overall cognitive development measured across many years. The E-Risk Longitudinal Study, a nationally representative 1994-5 birth-cohort of children in Britain (n = 1658 urban and suburban-dwelling participants), was used to test whether residential neighborhood greenery uniquely predicts children's cognitive development across childhood and adolescence. Greenery exposure was assessed from ages 5 to 18 using the satellite imagery-based normalized difference vegetation index (NDVI) in 1-mile buffers around the home. Fluid and crystalized intellectual performance was assessed in the home at ages 5, 12, and 18 using the Wechsler Intelligence Scale, and executive function, working memory, and attention ability were assessed in the home at age 18 using the Cambridge Neuropsychological Test Automated Battery. Children living in residences surrounded by more neighborhood greenery scored significantly higher, on average, on IQ measures at all ages. However, the association between greenery and cognitive measures did not hold after accounting for family or neighborhood socioeconomic status. After adjustment for study covariates, child greenery exposure was not a significant predictor of longitudinal increases in IQ across childhood and adolescence or of executive function, working memory, or attention ability at age 18. Children raised in greener neighborhoods exhibit better overall cognitive ability, but the association is likely accounted for by family and neighborhood socioeconomic factors.
