Objective:
A metabolism score for visceral fat (METS-VF) is an innovative method to access abdominal fat and visceral fat. So far, the relationship between the METS-VF index and chronic obstructive pulmonary disease (COPD) has remained unclear. We investigated the relationship between the METS-VF index and COPD prevalence utilizing data from the National Health and Nutrition Examination Survey (NHANES) 2007-2018.
Patients And Methods:
A binary logistic regression analysis was performed using NHANES 2007-2018 data to assess the relationship between the METS-VF index and COPD prevalence. The relationship was verified by fitted smooth curves, generalized additive models, threshold effect analyses, subgroup analyses, and sensitivity analyses.
Results:
In total, 7,680 subjects were recruited for the study, including 772 self-reported having COPD. The METS-VF index was positively related to COPD prevalence when adjusted for all covariates. The METS-VF index was classified by quartiles, and participants who scored highest on METS-VF were at a greater risk of COPD than those who scored lowest. According to a threshold effect analysis, the METS-VF index was negatively correlated with COPD prevalence with a METS-VF index <7.00, without statistical significance. Once the METS-VF index exceeded 7.00, there was a robust positive correlation between the METS-VF index and COPD prevalence. In the analysis of subgroups, the METS-VF index was positively correlated with COPD prevalence among subjects who were male, aged 40-59, and without asthma or hypertension. The results were robust in sensitivity analyses. METS-VF showed a significantly better diagnostic value for COPD than Body Mass Index (BMI).
Conclusions:
The METS-VF index has a non-linear and positive correlation with COPD prevalence in the middle-aged and elderly American population.

01:22Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.

Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
