“…31 For childhood asthma and atopy, there is some evidence though possibly restricted to specific settings with regional variation. [32][33][34] In our analysis, there was a clear gradient in population density, greenness, tree cover, and their counterpart soil sealing over the exposure strata (Figure 2). Apparently, the above pictured scenery for the farm children studies does not just seem a cliché, but was substantiated by objectively measured data.…”

“…More research is also needed to explain regional variations. We observed inconsistent associations by region for birth weight [12], allergic rhinitis [45], and asthma and allergy-related symptoms [26,45]. In addition, more research is required outside of North America and Europe, where most studies to date have taken place.…”

“…A study pooling data of seven cohorts from multiple countries found no associations between greenness and allergic rhinitis and aeroallergen sensitization [45]. While greenness was positively associated with allergic rhinitis in Swedish and southern German cohorts, it was negatively associated with this outcome in Dutch and northern German cohorts.…”

Purpose of review Many studies suggest that exposure to natural vegetation, or greenness, may be beneficial for a variety of health outcomes. We summarize the recent research in this area. Recent findings We observed consistent and strong evidence of associations for higher greenness with improvements in birth weights and physical activity, as well as lower mortality rates. Recent studies also suggested that exposure to greenness may lower levels of depression and depressive symptoms. The evidence on greenness and cardiovascular health remains mixed. Findings are also inconsistent for greenness measures and asthma and allergies. Summary Our knowledge of the impacts of greenness on a wide variety of health outcomes continues to evolve. Future research should incorporate information on specific species and some qualities of natural greenness that might drive health outcomes, integrate exposure assessments that incorporate personal mobility into analyses, and include prospective designs to add to the growing evidence that nature exposure positively affects health.

“…Indeed, some studies have shown that increases in the “normalized difference vegetation index” or NDVI, a measure of the greenspace in a given geographical area, is associated with decreased asthma prevalence (Sbihi, Tamburic, Koehoorn, & Brauer, ). However, other studies have shown no effects or negative effects of greenspace on asthma prevalence and control (Dadvand et al, ; Fuertes et al, ). One possible explanation for the mixed results is the failure to account for indicators of neighborhood safety, such as neighborhood violent crime rate and parent perceptions of neighborhood safety, which would affect parents’ willingness to allow their children to use greenspace.…”

Over 2 million children in the US have uncontrolled asthma. African American children are disproportionately affected with a risk of dying from asthma that is 7.6 times higher than non-Hispanic White children. Racial disparities in childhood asthma are partially attributed to differential exposures to poverty; unsafe and stressful neighborhoods; and unhealthy physical environments. This paper describes the protocol for an ongoing National Institutes of Health/National Institute of Nursing Research-funded descriptive, cross-sectional study to investigate two neighborhood factors that may influence children's asthma. Building on an existing dataset, this study examines associations among neighborhood greenspace, neighborhood safety, and level of asthma control while controlling for indoor asthma triggers in an urban sample of predominantly low-income, African American children with persistent asthma. Two new variables are added to the dataset: availability of neighborhood greenspace and neighborhood violent crime rate. Greenspace is being accessed using geographic information systems and measured using the normalized difference vegetation index. Neighborhood violent crime rate is calculated using geocoded, point locations for crimes downloaded from the city police department. It is hypothesized that parents living in unsafe neighborhoods are likely to keep their children indoors, thereby increasing their children's exposure to indoor asthma triggers and limiting the potential benefits of neighborhood greenspace. The biggest challenges thus far are related to limited variability in greenspace and violent crime rates. Progress to date and strategies to address these challenges are discussed. Results have the potential to inform interventions to improve asthmatic children's health and influence public health policy.

Residential greenness is differentially associated with childhood allergic rhinitis and aeroallergen sensitization in seven birth cohorts

Abstract: Although residential greenness appears to be associated with childhood allergic rhinitis and aeroallergen sensitization, the effect direction varies by location.
