Figure 7. DEP exposure exacerbates asthma severity and increases IL-17A in childhood allergic asthma.

Figure 7

(A) Among 235 GCPCR participants with allergic asthma, those with high DEP exposure (N=44) had more frequent asthma symptoms compared with those with low exposure. The observed association remained significant even after adjusting for age, race, sex, annual family income, type of health insurance, maternal education, being prescribed asthma controllers, adherence to asthma medication over the prior two weeks, and second-hand smoke exposure in multivariate logistic models (p=0.01). (B) Among 46 PEES asthmatics, 53% of children with high DEP exposure also had high levels of IL-17A. The association remained significant after adjustment for the above covariates and asthma symptom frequency.
