| Longitudinal | Frailty status | |||
| Robust | Pre-frail/frail | Model 1 | Model 2 | |
| (% (n)) | (% (n)) | OR (95% CI) | OR (95% CI) | |
| BMI and WC profile, baseline | 62.8 (870) | 37.2 (515) | ||
| Normal BMI and normal WC | 36.1 (314) | 29.1 (150) | Ref. | Ref. |
| Normal BMI and moderately high/high WC | 8.4 (73) | 8.0 (41) | 1.13 (0.73 to 1.74) | 1.01 (0.63 to 1.61) |
| Overweight and normal WC | 15.9 (139) | 9.5 (49) | 0.74 (0.50 to 1.08) | 0.79 (0.53 to 1.19) |

Model 1: adjusted for age at baseline. Model 2: adjusted for age, educational level, marital/cohabitation status, smoking status, alcohol intake, social support, self-perceived health and physical activity level at baseline.
BMI, body mass index; WC, waist circumference.
