Racial, Ethnic, and Socioeconomic Disparities in Multiple Measures of Blue and Green Spaces in the United States

BACKGROUND: Several studies have evaluated whether the distribution of natural environments differs between marginalized and privileged neighborhoods. However, most studies restricted their analyses to a single or handful of cities and used different natural environment measures. OBJECTIVES: We evaluated whether natural environments are inequitably distributed based on socioeconomic status (SES) and race/ethnicity in the contiguous United States. METHODS: We obtained SES and race/ethnicity data (2015–2019) for all U.S. Census tracts. For each tract, we calculated the Normalized Different Vegetation Index (NDVI) for 2020, NatureScore (a proprietary measure of the quantity and quality of natural elements) for 2019, park cover for 2020, and blue space for 1984–2018. We used generalized additive models with adjustment for potential confounders and spatial autocorrelation to evaluate associations of SES and race/ethnicity with NDVI, NatureScore, park cover, and odds of containing blue space in all tracts ([Formula: see text]) and in urban tracts ([Formula: see text]). To compare effect estimates, we standardized NDVI, NatureScore, and park cover so that beta coefficients presented a percentage increase or decrease of the standard deviation (SD). RESULTS: Tracts with higher SES had higher NDVI, NatureScore, park cover, and odds of containing blue space. For example, urban tracts in the highest median household income quintile had higher NDVI [44.8% of the SD (95% CI: 42.8, 46.8)] and park cover [16.2% of the SD (95% CI: 13.5, 19.0)] compared with urban tracts in the lowest median household income quintile. Across all tracts, a lower percentage of non-Hispanic White individuals and a higher percentage of Hispanic individuals were associated with lower NDVI and NatureScore. In urban tracts, we observed weak positive associations between percentage non-Hispanic Black and NDVI, NatureScore, and park cover; we did not find any clear associations for percentage Hispanics. DISCUSSION: Multiple facets of the natural environment are inequitably distributed in the contiguous United States. https://doi.org/10.1289/EHP1116

How do awareness, perceptions, and expectations of an urban greenway influence residents’ visits and recreational physical activity? Evidence from the Connswater Community Greenway, Belfast, Northern Ireland

The development of an urban greenway as part of a major regeneration project may encourage usage and recreational physical activity (PA). However, how the awareness and perceptions of such a project influence the usage of the greenway and recreational PA after regeneration remains unclear. This study focused on these relationships in the context of a major urban regeneration project, the Connswater Community Greenway (CCG) in Belfast, Northern Ireland. Data were collected from residents living near the CCG at 6 months postimplementation (2016/2017). Awareness, perceptions, and expectations of the CCG were assessed using several self-reported questions. Respondents were split into intervention and control groups based on a 1-mile threshold distance to the CCG from their home address (intervention group ≤1 mile; control group &gt;1 mile). Self-reported CCG usage included both frequency and duration of visits. Recreational PA was evaluated with the Global Physical Activity Questionnaire and PA stages of change measure. We used multilevel linear and logistic regressions to examine awareness, perceptions, and expectations of the CCG on visitation and recreational PA. Results showed that favorable awareness, perceptions, and expectations were positively associated with CCG visits and recreational PA. Frequent and longer durations of CCG visits were also important for encouraging recreational PA. These findings provide evidence that it is important to include awareness-raising programs and education regarding the urban greenway development for health benefits.<br/

Natural and built environments and blood pressure of Alpine schoolchildren

Background: Early life environments may influence children's blood pressure (BP), but evidence on the combined effects of natural and built environment exposures is scarce. The present study investigates the associations of natural and built environment indicators, traffic noise, and air pollution with BP in children living in Alpine valleys. Methods: In 2004/2005, 1251 school children (8-12 years old) were sampled for a cross-sectional survey in several Austrian and Italian mountain valleys. Children's mothers completed a questionnaire. The outcomes of interest were systolic and diastolic BP measured with a calibrated oscillometric device. Indicators of land cover assigned to the residential and school coordinates within 100 and 1000 m included normalized difference vegetation index (NDVI), tree canopy cover, and a broader naturalness indicator titled distance to nature (D2N). The presence of a home garden was also measured via self-report. Imperviousness density served as a proxy for the built environment. Residential air pollution (NO2) and noise (Lden) from traffic were calculated using bespoke modeling. NO2, Lden, physical activity, and body mass index (BMI) were treated as mediating pathways. Results: Higher NDVI and tree cover levels in residential and school surroundings and home gardens were consistently associated with lower BP. The built environment was associated with higher BP. Counterintuitive inverse associations between NO2 and Lden and BP were also found. SEM showed that higher levels of greenspace and presence of a home garden were weakly associated with more outdoor play spaces, and in turn with lower BMI, and ultimately with lower BP. Conclusions: Exposure to natural environments may help maintain normal BP in children, while built environment may increase children's BP. Outdoor play and less adiposity in greener areas may mediate some of these associations. Evidence on air pollution and noise remains controversial and difficult to explain
