Three‐year change in Health ABC Score by BMI variability quintile
| Quintile | ASV method | rASV method | ||
|---|---|---|---|---|
| β (95% CI) | P | β (95% CI) | P | |
| 1 | 0 (reference) | — | 0 (reference) | — |
| 2 | −0.01 (−0.07, 0.05) | 0.73 | 0.018 (−0.044, 0.080) | 0.58 |
| 3 | 0.00 (−0.063, 0.063) | 0.99 | −0.038 (−0.101, 0.024) | 0.23 |
| 4 | −0.034 (−0.098, 0.030) | 0.29 | −0.016 (−0.079, 0.048) | 0.63 |
| 5 | −0.094 (−0.162, −0.026) | <0.01 | −0.067 (−0.132, −0.003) | 0.04 |
Note: Greater reductions in Health ABC Score are observed in the highest quintile of BMI variability. Abbreviations: ABC, Aging and Body Composition; ASV, average successive variability; BMI, body mass index; CI, confidence interval; rASV, residual average successive variability.
