Association between FEV₁/FVC levels and all-cause mortality in the general population.

ABSTRACT:

Background

The ratio of the forced expiratory volume in 1 s (FEV₁) to the forced vital capacity (FVC) is an essential tool for the diagnosis of chronic obstructive pulmonary disease (COPD). However, the relationship between levels of FEV₁/FVC and mortality in the general population remains unclear, particularly its non-linear relationship. Therefore, we aimed to explore the association between the FEV₁/FVC and all-cause mortality in the general population.

Methods

The data of participants included in the National Health and Nutrition Examination Survey (1988-1994 and 2007-2012 cycles) were analyzed. Participants aged ≥20 years, who were not pregnant, who underwent quality-controlled lung function tests, and with follow-up data on mortality st
