Many studies have noted an association of ambient aeroallergen levels with exacerbation of asthma.
This study was undertaken to amine the relationship of aeroallergen levels with asthma-related mortality in Chicago.
The association of environmental aeroallergen levels with death caused by asthma among 5-to 34-year-olds in Chicago was examined for the period of 1985 through 1989.
Logistic regression analysis was used to compare the probability of a death caused by asthma occurring on the basis of environmental tree, grass, or ragweed pollen and mold spore levels.
Mean mold spore levels but not tree, grass, or ragweed pollen levelswere significantly higher for days on which asthma-related death occurred than for days on which no death occurred (z=2.80, p<0.005).
The odds of a death caused by asthma occuring on days with mold spore counts of 1000 spores per cubic meter or greater was 2.16 times higher (95% confidence interval=1.31,3.56, p=0.003) than on days on which mold spore counts were less than 1000 spores per cubic meter.
Although death caused by asthma also involves personal, social, and medical access factors, these data suggest that exposure to environmental molds may play a role in asthma-related mortality and should be considered in prevention strategies.
