| Outline of Final Research Achievements |
The aim of this study was to reveal the association between airflow limitation (AL) severity and reduction with work productivity among Japanese workers. This cross-sectional study included 1,860 workers in 2019 and 2,367 workers in 2021 who underwent a lung function test during a health checkup. Workers completed a questionnaire on productivity loss at work and sick leave. Logistic regression analysis was used to assess the associations between AL severity and the quality and quantity of productivity loss at work as well as use of sick leave. According to the analysis in 2019, compared with workers without AL, workers with moderate-to-severe AL showed a significant productivity loss after adjustment. AL severity was significantly associated with work productivity loss. Our findings suggested that early intervention in the subjects with AL at the workforce might be beneficial for promoting work ability.
