Variables associated with the evaluated outcomes in a multiple logistic regression model
| OR | 95% CI | P | |
|---|---|---|---|
| Dropout (yes/no) | |||
| Baseline BMI | 0.90 | 0.84–0.96 | < 0.001 |
| BDI score | 1.05 | 1.00–1.10 | 0.042 |
| SF-36 overall health score | 0.99 | 0.98–1.01 | 0.23 |
| Early vs late dropout* | |||
| Living alone | 2.01 | 0.90–4.47 | 0.08 |
| Baseline weight | 0.97 | 0.95–1.00 | 0.05 |
| Low SF-36 mental score | 5.06 | 2.27–11.3 | < 0.001 |
| Early dropout vs completers** | |||
| Living alone | 2.25 | 1.02–4.97 | 0.042 |
| Baseline BMI | 0.83 | 0.75–0.92 | < 0.001 |
| BDI score | 1.04 | 0.96–1.13 | 0.32 |
| BES score | 1.00 | 0.96–1.04 | 0.88 |
| Low SF-36 overall health score | 1.64 | 0.68–3.97 | 0.27 |
| Low SF-36 mental score | 3.17 | 1.17–8.59 | 0.022 |
*The same model was repeated by adjusting for baseline waist circumference instead of baseline weight and the results did not significantly change
**The same model was repeated by adjusting for baseline waist circumference instead of baseline BMI and the associations with low SF-36 mental score remained statistically significant (OR = 2.64; 95%CI 1.01–6.88; p = 0.045)
