Analysis of pulmonary function test results in a health check-up population.

Abstract

To explore the incidences of chronic obstructive pulmonary disease (COPD), obstructive ventilatory dysfunction, and obstructive small airway disease and their risk factors in a health check-up population, with an attempt to inform the early diagnosis and treatment of COPD. Subjects who aged 20 years and older and received health check-up in the Health Management Center, Third Xiangya Hospital, Central South University from June 2013 to June 2015 were enrolled in this study. The results of detection and survey for COPD, obstructive ventilatory dysfunction, and obstructive small airway disease were analyzed. Among 6,811 subjects enrolled in this study, the detection rate of COPD, obstructive ventilator dysfunction, and obstructive small airway disease was 0.8%, 2.6%, and 4.0%, respectively, which showed a positive correlation with male gender, age, and smoking index. Health check-up is an important approach for screening COPD, obstructive ventilator dysfunction, and obstructive small airway disease. Smoking cessation and controlling of relevant risk factors are helpful to lower the incidences of these conditions.
