Abstract
ObjectivesThe present study aimed to investigate the relationship between airflow limitation (AL) severity and comorbidities in comprehensive health examination.MethodsThis cross-sectional study included 6661 men and 6044 women aged 40–89 who underwent a lung function test during medical checkups. AL was defined as forced expiratory volume in 1 s/forced vital capacity of < 0.7. Logistic regression analysis was used to assess the association between AL severity and the presence of comorbidities.ResultsWhen compared with the normal lung function group, subjects with AL had a higher prevalence of lung cancer (odd ratio (OR) 9.88, 95% confidence interval (CI) 3.88–25.14) in men, hypertension (OR 1.63, 95% CI 1.26–2.10) in women, diabetes and hyperglycemia (OR 1.23, 95% CI 1.02–1.49 in men, OR 1.61, 95% CI 1.18–2.20 in women) in men and women after adjusting for potential confounders. In men, lung cancer and MetS (the Joint Interim Statement: JIS) were significantly associated with moderate-to-very severe AL after adjustment. In women, hypertension, diabetes and hyperglycemia, MetS (JIS), and MetS (the Japanese Committee of the Criteria for MetS: JCCMS) were significantly associated with mild AL after adjustment. Hypertension was significantly associated with moderate-to-very severe AL after adjustment in women.ConclusionsSignificant relationships were found between AL severity and the presence of comorbid lung cancer in men, hypertension in women, diabetes and hyperglycemia, and MetS in men and women. Knowledge of comorbidities associated with AL should be widely publicized to raise the awareness of chronic obstructive pulmonary disease (COPD).
Highlights
Chronic obstructive pulmonary disease (COPD), a common preventable and treatable disease, is characterized by persistent airflow limitation that is usually progressive and associated with an enhanced chronic inflammatory response in the airways and the lung to noxious particles or gases [1, 2]
This study focused on the prevalence and risks of comorbidities in those who received comprehensive health examination according to their lung function
We demonstrated that the odds ratio for having lung cancer compared to those with normal lung function was 6.52 in subjects with mild Airflow limitation (AL) and 12.58 in subjects with moderate-to-very severe AL in men, whereas there was no significant difference in women
Summary
Chronic obstructive pulmonary disease (COPD), a common preventable and treatable disease, is characterized by persistent airflow limitation that is usually progressive and associated with an enhanced chronic inflammatory response in the airways and the lung to noxious particles or gases [1, 2]. COPD is a leading cause of morbidity and mortality worldwide and results in an economic and social burden that is both substantial and increasing [1, 2]. The burden of COPD is still expected to continue increasing [3]. COPD frequently coexists with other conditions often known as comorbidities that may have a significant impact on prognosis [1, 2]. Most common comorbidities are cardiovascular disease, hypertension, metabolic syndrome
