Occupational risk for adult-onset asthma by various exposure measures among 1,482 subjects.

Exposure Measure	OR (95% CI)	PAR% (95% CI)
Vapors, gas, dust, or fumes (VGDF)	1.7 (1.03 to 2.8)*	17% (0% to 32%)
Any of 16 specific exposures	1.6 (0.98 to 2.7)†	19% (−3% to 36%)
Either VGDF or any of 16 exposures	1.7 (1.0 to 2.8)*	24% (0% to 42%)
Both VGDF and any of 16 exposures	1.7 (1.0 to 2.9)†	14% (−2% to 22%)
Asthma JEM, intermediate–high exposure	1.2 (0.7 to 2.1)	5% (−11% to 19%)

^*OR p ≤0.05

N=1,482 after exclusion of subjects reporting COPD, chronic bronchitis, emphysema, or asthma with onset prior to age 18. See Methods.

Multiple logistic regression analysis includes age, gender, race, and smoking status

OR = Relative odds. CI = Confidence interval. JEM = job exposure matrix
