Exploring the association between park size and crime.

This study explored the link between park size and crime risk in Alabama, analyzing 564 parks across 73 cities with populations over 10,000. Park dimensions were measured using Google Earth Pro, and crime data, covering violent and property crimes, were sourced from Applied Geographic Solutions. Additional data on population density, mental health prevalence, social vulnerability, and alcohol expenditure (indicative of affluence) were obtained from the U.S. Census Bureau, CDC, and ESRI. A multiple regression analysis revealed a significant negative association between park size and crime risk, meaning that larger park sizes tended to have lower crime rates. Key covariates-mental health, social vulnerability, and alcohol spending- were also significantly related to crime rates. Our findings have policy implications for local governments and community organizations seeking to reduce crime rates.

Changes in cortisol and dehydroepiandrosterone levels immediately after urban park visits.

The purpose of this study is to explore physiological and psychological changes immediately after a short-term visit to urban parks in an uncontrolled condition. Sixty park visitors completed a short questionnaire evaluating their subjective well-being (SWB) and donated a saliva sample immediately before and after their park visit. In addition, participants wore a pedometer to track their physical activity level during the park visit. Results indicated the levels of all biomarkers (cortisol, dehydroepiandrosterone [DHEA], and cortisol/DHEA ratio) decreased while SWB scores increased after the park visit. The duration of park visit was identified as a key variable significantly associated with cortisol reduction, and changes in SWB scores after the park visit were significantly associated with changes in cortisol level. A park visit duration of 21.8 min has the predictive ability to discriminate park visitors who exhibit reductions in cortisol levels after the park visit from those who do not.

What are the factors associated with neighborhood park visits and health in Alabama? A cross-sectional study using a path model.

This study seeks to examine the effect of the characteristics of park users, park characteristics, and the neighborhood environment on park visits and the resultant perceived health status of residents living in Alabama, US. One hundred and eighty-nine participants, representing residents from 49 counties in Alabama, were recruited via a random-digit dial method to complete a telephone survey related to park visits. Data collection spanned 11 months. Results from the path analysis indicated a few significant direct effects: park location and body mass index (BMI) were the only two factors significantly associated with park visits, with race being marginally significant; and work status was significantly associated with perceived health. Our findings suggest park proximity, and high BMI are related to park visits and work status is related to perceived health among Alabamians. It is recommended that more neighborhood parks are needed for promoting Alabamians to visit them more frequently.

Residential Greenness Positively Associated with the Cortisol to DHEA Ratio among Urban-Dwelling African American Women at Risk for HIV.

As ecosystems that support human health, societies, and civilization change in the era of the Anthropocene, individuals with disproportionate balance of salivary hormones may be at greatest risk of morbidity and mortality. Vulnerable communities, in particular, are overburdened by inequities in features of built environments linked to health disparities. This study examined the cross-sectional association of greenness in the built environment with the ratio of cortisol to dehydroepiandrosterone (DHEA) in an urban-dwelling high-risk community sample of African American women (n = 84, age 18-44 years). Saliva samples, collected across 2 consecutive days, were assayed for cortisol and DHEA. Controlling for sexual violence, perceived stress, education, and income, as well as crime, traffic density, and vacant properties, we observed a significant positive cross-sectional association between greenness and the cortisol to DHEA ratio, (ß = 7·5, 95% CI: 0.89, 14.19). The findings highlight environmental influence on stress response at waking when there is the greatest individual variation. Implications for advancing our understanding of the waking ratio of cortisol to DHEA as a potential marker of physiological resilience are discussed.

Integrative Review of the Intersection of Green Space and Neighborhood Violence.

PURPOSE: To systematically analyze evidence about the impact of green space on the perception and actual safety of residents of urban neighborhoods. DESIGN AND ORGANIZING CONSTRUCT: Systematic review of green space and violence based on Broome review criteria. METHODS: One landmark study prompted the initial hand search and identification of search terms. Twenty-three quantitative, five qualitative, and two mixed-methods studies were found in the urban planning, public health, medical, and psychological literature that met the following criteria: analyzed green space and violence as factors in the perception of safety as an outcome measure, including action taken by being outside for recreation, exercise, or self-report in the survey. FINDINGS: Findings were inconsistent regarding the direct relationship between perception of safety and green space when using recreation and exercise as a proxy for perception of safety. Findings regarding perception of safety in surveys were limited but indicated a positive correlation with green space. There is sufficient evidence to conclude that the perception of safety is supported by quality, accessibility, and aesthetic dimensions of neighborhood green space, and the perception of safety is often unrelated to actual crime rates. CONCLUSIONS: The science for understanding mechanisms between green space and violence as part of environmental health has been insufficiently developed and requires further study. Environmental health, including green space, is central to health promotion, and understanding is key to preventing the epidemic of violence. CLINICAL RELEVANCE: This article provides a summary of research related to green space, violence in communities, perception of safety, and violent crime in those communities. It identifies gaps in our knowledge where future research is needed. Nurses have the opportunity to lead the development, implementation, and evaluation of evidence-based interventions and policies addressing the inequality of quality and quantity of green space in the built and natural environment and related co-benefits.

Greenness and the Potential Resilience to Sexual Violence: "Your Neighborhood Is Being Neglected Because People Don't Care. People With Power Don't Care".

There is increasing evidence that green space in communities reduces the risk of aggression and violence, and increases wellbeing. Positive associations between green space and resilience have been found among children, older adults and university students in the United States, China and Bulgaria. Little is known about these associations among predominately Black communities with structural disadvantage. This study explored the potential community resilience in predominately Black neighborhoods with elevated violent crime and different amounts of green space. This embedded mixed-methods study started with quantitative analysis of women who self-identified as "Black and/or African American." We found inequality in environments, including the amount of green space, traffic density, vacant property, and violent crime. This led to 10 indepth interviews representing communities with elevated crime and different amounts of green space. Emergent coding of the first 3 interviews, a subset of the 98 in the quantitative analysis, led to a priori coding of barriers and facilitators to potential green space supported community resilience applied to the final 7 interview data. Barriers were a combination of the physical and social environment, including traffic patterns, vacant property, and crime. Facilitators included subjective qualities of green space. Green spaces drew people in through community building and promoting feelings of calmness. The transformation of vacant lots into green spaces by community members affords space for people to come together and build community. Green spaces, a modifiable factor, may serve to increase community resilience and decrease the risk of violence.

Nature-Based Therapies for Sleep Disorders in People Living with Human Immunodeficiency Virus.

Following diagnosis of human immunodeficiency virus (HIV), getting adequate sleep may be the farthest thing from the mind of patients or providers. Even further from mind are the potential benefits on both sleep and HIV from nature-based therapy. In developing and developed countries, access to high-quality natural spaces has the potential to support physical and mental health. This article provides a review of sleep disorders, conventional and nature-based therapies, and the potential of nature-based therapy to support the health of people living with HIV through increased restorative sleep and immune function.
