Severity of Airflow Obstruction and Work Loss in a Nationwide Population of Working Age.

ABSTRACT: The impact of COPD severity on labor force participation and work loss is not well known. This study aimed to describe the characteristics of occupations and to evaluate the reason for work loss based on the severity of airflow obstruction (AO).
