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.
