Development and Validation of the Mexican Public Open Spaces Tool (MexPOS).

Public open spaces (POS) are "publicly owned spaces such as parks, green areas, squares, marketplaces, streets and highways which are of public access". Some attributes could increase or decrease participants' attendance. Thus, reliable and valid audit tools are needed in order to measure these attributes. This study aimed to develop and validate a tool to assess POS features within the Mexico City context. The Mexican Public Open Spaces Tool (MexPOS) was developed based on (1) two validated POS audit tools, (2) several visits to the POS, (3) pilot testing, and (4) multiple work sessions with a group of specialists. The original tool included 181 items divided into nine sections. Trained personnel visited and evaluated 944 POS in Mexico City. An exploratory factor analysis was performed to examine the construct validity of the items and the relationship between the subscales. The final model resulted in seven factors: (1) Food and Wellness Environment (α = 0.15), (2) Maintenance (α = 0.81), (3) Amenities (α = 0.72), (4) Legibility (α = 0.59), (5) Security (α = 0.48), (6) Perceived Environment (α = 0.65), and (7) Urban Environment (α = 0.58). Our study highlights the relevance of using a validated tool to measure POS characteristics related to participants' attendance to help assess infrastructure improvements and identify priority areas for changing socio-urban environments for physical activity.

Use of an Elevated Avenue for Leisure-Time Physical Activity by Adults from Downtown São Paulo, Brazil.

Leisure-time physical activity (LTPA) is associated with access and use of public open spaces. The President João Goulart Elevated Avenue, currently denominated Minhocão, is a facility for leisure activities that is open for people during the night and weekends. The aim of this study was to examine if the prevalence of LTPA among individuals living in the surroundings of Minhocão is different according to proximity to, and use of, the facility. We conducted a cross-sectional study with cluster sampling with people aged ≥18 years who lived in households up to 500 m, and between 501 m and 1500 m of Minhocão. The survey was conducted between December 2017 and March 2019 using an electronic questionnaire. We conducted a bivariate analysis and Poisson regression to examine possible differences in LTPA according to the proximity of residences and use of Minhocão. The analysis used post-stratification weights. A total of 12,030 telephone numbers of people were drawn (≤500 m = 6942; and >500 m to ≤1500 m = 5088). The final sample included 235 residents who returned the questionnaires. There was a higher prevalence of individuals engaging in at least 150 min per week of LTPA among users than non-users (Prevalence Ratio = 2.19, IC95% 1.66 to 2.90), independently of sex, age, education, the distance of houses to nearest accesses and number of barriers. The main five barriers related to the usage of the Minhocão were safety issues in and around the Minhocão, rainy weather, lack of vegetation, and lack of facilities. People who used the park had higher prevalence of all types of LTPA than non-users. The results can serve to inform government decision-making on the future of Minhocão.

A Systematic Review of Objective Factors Influencing Behavior in Public Open Spaces.

As a significant part of outdoor built-environment, public open spaces are closely associated with people's daily lives. Studies of outdoor behavior in these spaces can shed light on users' environmental perceptions and contribute to the promotion of physiological and psychological health. Many recent studies are case studies focused where observations, surveys and interviews have been conducted to understand the factors influencing people's behavior on one or few sites or city environments. There have been few reviews related to this topic, and none have been based on the systematic understanding of influencing factors. This paper presents a systematic review of interactions between behavior and the built environment in public open spaces, and highlights the impacts of diverse and objective influencing factors. Followed the rules of PRISMA method (Preferred Reporting Items for Systematic Reviews and Meta-Analyses), 109 papers published in 2000-2021 were selected and reviewed. The distribution of the studied interactions is analyzed, and the impacts of four distinct factors: personal background, location and context, environmental component, and climate stimuli, are extracted, categorized, and specified. Moreover, outdoor health benefits are discussed based on which, crucial factors that require emphasis after the outbreak of COVID-19 are identified. Throughout this paper, behavioral influencing processes, including objective influencing factors, subjective feedback, and the relationships involved, are considered to provide a comprehensive picture. With the robust classification of existing factors, architects, urban designers, policy makers and fellow researches could be easier to get a more comprehensive trend from the past. This paper also provides guidance for future research, especially given that COVID-19 has created huge changes to outdoor needs and customary behavior.

Do we have enough recreational spaces during pandemics? An answer based on the analysis of individual mobility patterns in Switzerland.

Densification of cities threatens the provision of public open space for people living in and around cities. The increasing evidence of the many benefits of recreational walking for physical and mental health during the COVID-19 pandemic has highlighted an urgent need for fostering the availability of public open space. In this context, urban planners need information to anticipate recreational needs and propose long-term, resilient solutions that consider the growing demand driven by increasing urban population and intensified in times of crisis such as the recent pandemic. In this paper, we harness the unique large MOBIS:COVID-19 GPS travel diary data on mobility behaviour collected during a normal baseline period and during the first wave of the Covid-19 pandemic in the Canton of Zurich Switzerland. We estimate a sufficiency rate that allows to geolocate locations where the demand for public open space is higher than the available offer. In a second step, we explore if preference patterns for recreational areas have changed during the pandemic. Results indicate that the main cities and important towns in the case study area are saturated by current demand, and that the pandemic has amplified the problem. In particular, urban dwellers look for tranquil areas to recreate. Such information is crucial to guide decision-making processes for planning the cities of the future.

Participation and Physical Activity in Recreovia of Bucaramanga, Colombia.

BACKGROUND: Open Streets initiatives have allowed for physical activity (PA) in cities worldwide. However, few studies have evaluated the use of small Open Streets in low- and middle-income countries, such as those in Latin America. Thus, this study aimed to describe participation and PA level of users in the Recreovia program in Bucaramanga, Colombia. METHODS: A cross-sectional study was conducted during 5 Sundays from September to November 2017. Recreovia use was evaluated at 4 strategic points according to street accessibility (2 points) and aerobics class areas (2 points), using the System for Observing Play and Recreation in Communities. RESULTS: A total of 38,577 observations were made (34,969 on streets and 3608 in aerobics class areas). Men (63%) and adults (62%), with moderate to vigorous PA (MVPA) (98%) were observed on streets. The most common PAs were biking (50%), walking/dog walking (36%), and jogging (9%). In aerobics class areas, the most common groups were female (65%) and adults (89%). Participants were engaged in moderate to vigorous PA (91%). CONCLUSION: Measurement of number of participants at moderate to vigorous levels of PA was high. A difference between sexes and age in these street and aerobic class area groups was also observed.

Resumen: Objetivo: Describir la evidencia disponible sobre la transmisión por Covid-19 e infecciones respiratorias agudas similares al Covid-19 en espacios públicos abiertos. Material y métodos: La búsqueda incluyó 4 926 artículos en inglés de los años 2000 a 2020. Seis investigadores revisaron el título y el resumen de los artículos de Embase y PubMed; dos investigadores revisaron los de medRxiv. Todos los investigadores revisaron textos completos y otros resolvieron las discrepancias. Resultados: De los 21 artículos seleccionados, se observó que la presencia de virus en superficies públicas, aguas residuales y áreas exteriores no fue indicativa de transmisión. No obstante, se observó que el uso de cubrebocas, el lavado de manos, el distanciamiento social, no asistir a eventos masivos y la movilidad individual a espacios públicos podría ayudar a reducir el riesgo de transmisión. Conclusión: Esta información podría coadyuvar a generar recomendaciones en salud pública, sin embargo, es recomendable actualizar esta revisión conforme avance la evidencia científica.

Abstract: Objective: To describe the available evidence on the transmission of Covid-19 or similar acute respiratory infections in open, public spaces. Materials and methods: Our search included 4 926 articles in English from 2000 to 2020. Six researchers reviewed the title and abstracts from Embase and PubMed databases, and two researchers reviewed medRxiv database. All reviewed full texts and others resolved the discrepancies. Results: A total of 21 articles were selected. The presence of the SARS-CoV-2 virus on public surfaces, sewage, and outdoor areas was not indicative of transmission. Nevertheless, we observed that applying preventive measures such as the use of face masks, hand washing, social distancing, restricting attendance to massive events, and reducing people's mobility to public spaces may reduce the risk of transmission. Conclusions: This information could help to generate public health recommendations. However, we advise updating this review as new evidence is generated.

A Proposed Planning Concept for Public Open Space Provision in Saudi Arabia: A Study of Three Saudi Cities.

Public open spaces (POS) have an essential positive impact on cities and their residents. These spaces play a critical role in enhancing users' physical, mental, and social wellbeing. In addition, POS improve city resilience and economic value, and act as part of the city's visual amenities. The Kingdom of Saudi Arabia is taking many approaches to enhance quality of life in all its cities through initiatives such as increasing the POS area per capita. Several studies have examined the importance of the accessibility of POS in addressing users' needs. In this study, we measured the per capita area and accessibility of POS in the three megacities Riyadh, Dammam, and Jeddah. We also collected data on user preferences for the use of POS through semi-structured interviews, observations, and an online questionnaire. This study suggests that the country needs to establish its own POS planning approach based on users' desires and behaviors when using POS, as well as the country's social characteristics, and to depend not only on standard international planning approaches. The paper recommends considering the possibility of increasing POS by creating typologies of these spaces based on each city's landscape characteristics. This proposal will have a major impact on city planning and design in Saudi Arabia. In addition, it will make the Saudi cities livable and have a positive impact on the physical, mental, and social wellbeing of the population.

Outdoor thermal comfort and adaptive behaviors in the residential public open spaces of winter cities during the marginal season.

In winter cities, outdoor seasons are highly valued due to the long cold winter. By improving the outdoor thermal environment during marginal seasons, outdoor seasons may be extended. Therefore, outdoor thermal comfort and adaptive behaviors during marginal seasons should be considered. Three representative residential public open spaces in Harbin, a typical winter city, were selected to conduct an empirical study. Meteorological measurements and rudimentary questionnaires were administered and observations were conducted to explore outdoor thermal comfort and adaptive behaviors. Three important conclusions were obtained from the survey. The result from the questionnaire surveys showed that users of public spaces generally believed that "warm" was comfortable during the spring marginal season of the winter cities. The 90% thermal acceptable physiologically equivalent temperature (PET) range, which was calculated using meteorological measurements and questionnaire results, was more than 10.2 °C for this time period in the winter cities. This threshold value was much lower than that of temperate and subtropical zones, indicating that the outdoor thermal comfort of users in the winter cities had regional characteristics. Moreover, users engaged in static vs. dynamic activities showed different sensitivities to thermal environments. The users' location selection showed a strong dependence on microclimate rather than on the activity-supported facilities; when microclimate conditions changed, users made accommodations by moving to sunny areas or performing other adaptive behaviors, and thus, space utilization changed. These findings can inform thermal comfort-oriented planning and design from the perspectives of microclimate regulations, site planning, and activities in the residential public open spaces of winter cities.

Built environment and physical activity: domain- and activity-specific associations among Brazilian adolescents.

BACKGROUND: Physical activity is likely to be determined as a complex interplay between personal, interpersonal, and environmental factors. Studying the built environment involves expanding the focus from the individual perspective to a public health one. Therefore, the objetive of this study was to examine the association between the built environment and objectively-measured physical activity among youth. METHODS: Cross-sectional analysis of data from of a Brazilian birth cohort during adolescence. Physical activity was measured using accelerometers (GENEActiv) and self-report (International Physical Activity Questionnaire, long version). Participants' home addresses were geocoded and built environment characteristics such as streets' pattern and quality, and public open spaces attributes for physical activity practice were evaluated in a 500-m circular buffer surrounding their homes. RESULTS: A total of 3379 participants were included. Street lighting (ß = 2.2; 95%CI: 0.5; 3.9) was positively associated with objectively-measured moderate-vigorous physical activity (MVPA) and proportion of paved streets and buffer's average family income were associated with lower MVPA. Living near the beach increased the odds of leisure-time MVPA practice by 3.3 (95%CI: 1.37; 8.02) times. There was a built environment-by-socioeconomic status (SES) interaction for the associations with commuting physical activity; street lighting [Odds ratio (OR) = 1.22; 95%CI: 1.01; 1.47] and presence of cycle lanes (OR = 1.77; 95%CI: 1.05; 2.96) were positively associated with commuting physical activity only among the intermediate SES tertile. CONCLUSION: Beachfront, street lighting, paved streets and cycle lanes were associated with physical activity patterns. This suggests that infrastructure interventions may influence physical activity levels of Brazilian adolescents.

Public Open Spaces and Leisure-Time Walking in Brazilian Adults.

Access to public open space is important to increase leisure-time walking (LTW) in high-income countries, but there is little evidence in middle-income countries. We conducted a cross-sectional analysis to examine the relationship between LTW and the presence of different public open spaces (parks, bike paths, and squares) and the mix of these recreational destinations near the homes of adults participating in the Sao Paulo Health Survey (n = 3145). LTW was evaluated by a questionnaire. We delineated buffers (500, 1000, and 1500 m) from the geographic coordinates of the adults' residential addresses using a geographic information system. We used multilevel logistic regression taking account of clustering by census tracts and households, and with adjustment for social, demographics, and health characteristics. The main results showed that the presence of at least two recreational destinations within a 500-m buffer of participants' homes were associated with an increased odds of LTW compared with no destinations present (OR = 1.65; 95% CI 1.09-2.55). No associations were found for destinations further away. These results support actions outlined in the new urban plan for Sao Paulo city and could be used to highlight the importance access to a mix of public open spaces to promote physical activity in megacities of middle-income countries.
