Abstract

BACKGROUND
The prevalence of metabolic syndrome and obesity has been increasing. Reports on literature concerning the effects of these two diseases on pulmonary function have been inconclusive. This study aimed to determine any correlation between pulmonary function with variable factors from the diagnostic criteria of metabolic syndrome and body composition analysis.
METHODS
We reviewed the medical records of 1962 subjects (27.7% males and 72.3% females) who visited the health promotion center at a tertiary hospital from January 2010 to December 2010. We investigated the correlation between pulmonary function with metabolic syndrome, BMI, fat percentage, and fat mass. Metabolic syndrome was diagnosed by using the diagnostic criteria of the AHA/NHLBI (American Heart Association/National Heart, Lung and Blood Institute).
RESULTS
There were negative correlations between FEV1/FVC with HDL-C (P < 0.001) and hypertension (P < 0.05), and between FEV1, FVC, FEV1/FVC with fat percentage and fat mass (P < 0.05), respectively in men. In women, FEV1 and FVC were lower in hypertension group, and BMI was negatively correlated with FEV1/FVC.
CONCLUSION
Variables affecting pulmonary function differed by gender, and no statistically significant independent factors were found.
