Purpose: The purpose of this study was to examine the impact of body mass index (BMI) and waist circumference (WC) for pulmonary function in normal-weight and obese women.
Methods: Data from women aged ≥40 years were obtained from the 2011 Korean National Health and Nutrition Examination Survey. Obesity was measured by BMI and WC and pulmonary function was measured by forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), and a ratio between forced expiratory volume in 1 second
(FEV1/FVC). Multiple linear regression analysis was performed for assessment of the association between FVC, FEV1, FEV1/FVC and obesity variables.
Results: BMI showed positive association with FVC, FEV1, FEV1/FVC, and WC showed positive association with FEV1 and FEV1/FVC in normal-weight women. BMI and WC showed negative association with FVC, FEV1 in obese women. A 1 unit increase in BMI showed an association with a 25-mL reduction in FVC and a 19-mL reduction in FEV1. A 1-cm increase in WC showed an association with a 6-mL reduction in FVC and a 4-mL reduction in FEV1.
Conclusions: BMI and WC showed negative association with pulmonary function in obese adult women.
Therefore, obese women with reduced pulmonary function should be encouraged to lose weight for improvement of their pulmonary function.
