Airflow obstruction among ever‐employed U.S. adults aged 18‐79 years by industry and occupation: NHANES 2007‐2008 to 2011‐2012

Introduction

This study estimated the prevalence of spirometry‐defined airflow obstruction by industry and occupation and chronic obstructive pulmonary disease (COPD) among ever‐employed U.S. adults.

Methods

Data came from the National Health and Nutrition Examination Survey (NHANES) 2007‐2008 to 2011‐2012, a nationally representative study of the non‐institutionalized civilian U.S. population. Data on respondent's current and/or longest held job were used to create prevalence estimates and adjusted prevalence odds ratios (PORs) for airflow obstruction and COPD.

Results

Among ever‐employed U.S. adults, airflow obstruction prevalence was 12.40% and COPD was 3.47%. High airflow obstruction prevalence and significant PORs were reported in mining; manufacturing; construction; and services to buildings industries as well as extraction; bookbinders, prepress, and printing; installers and repairers; and construction occupations.

Conclusion

Prevalence of airflow obstruction varies by industry and occupation. Industries and occupations with increased risk were identified using the most current NHANES data including detailed occupations and spirometry.
