Greenness, trees and allergenic trees and allergic outcomes: main results
Birth home addresses surrounded by medium greenness (second NDVI tertile) in a 500 m buffer were associated with increased prevalence of asthma up to 15 years (odds ratio (OR) = 1.46) (Table 3). Home addresses with high greenness (third NDVI tertile) showed decreased prevalence of asthma (OR = 0.44). Medium numbers of allergenic trees (second tertile) according to definition 1 were related to higher prevalence of asthma (OR = 1.92). This was not the case for definition 2. Medium and high numbers of trees and allergenic trees according to the both definitions were associated with higher prevalence of AR (Table 3). All exposures were related to higher allergic sensitization to aeroallergens, and high numbers of allergenic trees according to definition 1 were related to food sensitization.
