Background: Regarding the importance of obesity in patients with chronic obstructive pulmonary disease (COPD), we aimed to evaluate of correlation between metabolic syndrome (MetS) and COPD.
Methods: In this cross-sectional study, 96 patients with COPD were evaluated. This study was conducted in 2016-2018. The severity of COPD was determined by Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2017 criteria. We investigated the correlations between MetS with COPD and possible diagnostic tools.
Results: Of all COPD patients, 86.5% had MetS, and the means of waist circumference, fasting blood glucose, systolic and diastolic blood pressure, body mass index, and triglyceride in patients with MetS were significantly higher than the patients without MetS (P < 0.05). We showed that forced expiratory volume in 1 second (FEV1) with a 37% cutoff had 92.8% and 69.2% sensitivity and specificity, respectively (area of the curve: 0.51, 0.31-0.71).
Conclusion: MetS is prevalent among COPD and FEV1 could be considered as important diagnostic tool for COPD.
