Table 4. Estimates (95% CIs) for the coefficient of BMI in conditional logistic regression analysis adjusted for selected lung function and sensitisation and also for other factors found to be associated with obesity in Table 1 .
| Lung and sensitisation factors | Males | Females |
|---|---|---|
| None | 1.11 (1.03, 1.19) | 1.38 (1.23, 1.56) |
| FEV1 | 1.10 (1.02, 1.18) | 1.37 (1.22, 1.54) |
| FVC | 1.11 (1.03, 1.19) | 1.40 (1.24, 1.57) |
| Sensitisation to more than one allergen | 1.09 (0.99, 1.19) | 1.25 (0.96, 1.60) |
| FEV1+sensitisation to more than one allergen | 1.09 (0.98, 1.19) | 1.28 (0.96, 1.69) |
| FVC+sensitisation to more than one allergen | 1.09 (0.99, 1.19) | 1.25 (0.97, 1.61) |
Abbreviations: BMI, body mass index; CI, confidence interval; FEV1, forced expiratory volume in 1 s; FVC, forced vital capacity.
