Contribution of different tertiles of the body mass index to all-cause mortality.
| Hazard Ratio (95% CIs) | Std. Err. | Wald χ 2 | P value | |
|---|---|---|---|---|
| Model 1 | ||||
| Body mass index (kg·m−2) | ||||
| First tertile | 1.69 (0.99–2.88) | 0.46 | 1.91 | 0.056 |
| Second tertile | 1 [reference] | |||
| Third tertile | 1.17 (0.66–2.07) | 0.34 | 0.54 | 0.588 |
| Model 2 | ||||
| Body mass index (kg·m−2) | ||||
| First tertile | 2.36 (1.30–4.30) | 0.72 | 2.81 | 0.005 |
| Second tertile | 1 [reference] | |||
| Third tertile | 0.96 (0.52–1.77) | 0.30 | −0.12 | 0.904 |
| Log-waist circumference [ln(cm)] | 20.35 (1.62–254.79) | 26.24 | 2.34 | 0.019 |
| Model 3 | ||||
| Body mass index (kg·m−2) | ||||
| First tertile | 1.54 (0.83–2.86) | 0.49 | 1.38 | 0.168 |
| Second tertile | 1 [reference] | |||
| Third tertile | 1.49 (0.80–2.76) | 0.47 | 1.25 | 0.211 |
| Log-general cardiovascular risk | 2.81 (2.11–3.75) | 0.41 | 7.02 | <0.001 |
| Log-waist circumference [ln(cm)] | 0.65 (0.04–10.50) | 0.93 | −0.30 | 0.763 |
†Cox proportional hazard models were used to calculate HRs and 95% CIs. Model 1: adjusted with BMI. Model 2: adjusted with BMI and waist circumference. Model 3: adjusted with BMI, waist circumference, and general CVD risk.
