^*RSE for the estimated prevalence with airflow obstruction >30% and ≤36%.

^**RSE for the estimated prevalence with airflow obstruction >36% and results are not presented.

^aAge-standardized prevalence estimates were based on the age distribution of the 2000 U.S. Census Population 18–79 age structure. NHANES examination sampling weights were used for airflow obstruction.

^bThe industry groups were created by combining four-digit industry codes from the U.S. Census Bureau’s 2002 version of its Occupation and Industry coding system.

^c40 participants were missing industry data or were uncodable.

^dPOR adjusted for age, gender, race/Hispanic origin, and smoking status.
