Summary of significant correlations between respiratory function parameters and body fat variables
| Dependent variable | Independent variable | |
| Females | ||
| Negative | FVC, TLC, RV, FRC, ERV | Weight, waist circumference, hip circumference |
| Negative | FRC, ERV | WHR |
| Positive | FEV1/FVC | DXA measured abdominal fat |
| Negative | FVC, TLC, RV, FRC, ERV | All DXA variables |
| Males | ||
| Positive | FEV1/FVC | Weight, waist circumference |
| Negative | FVC | Waist circumference, WHR |
| Negative | FRC, ERV | Weight, waist circumference, hip circumference, WHR |
| Positive | FEV1/FVC | All DXA variables, except thoracic fat and tertiles 1 and 2 |
| Negative | FVC, TLC, FRC, ERV | All DXA variables, except tertile 1 |
FVC: forced vital capacity; TLC: total lung capacity; RV: residual volume; FRC: functional residual capacity; ERV: expiratory reserve volume; WHR: waist/hip ratio; FEV1: forced expiratory volume in one second; DXA: dual-energy X-ray absorptiometry.
