Multivariable Associations of Weight Change With Survival to Age 95 vs Death Before Age 95 Among Older Women, 1993 to 2022
Variable | No./Total (%) Survived to Age 95, y* |
OR (95% CI)† |
---|---|---|
No./total (%) survived to age 95 | 8 140/28 014 (29.1) | |
3-Y weight change | ||
Stable weight (within ± 5% change) | 5 974/19 098 (31.3) | 1.00 |
Weight loss (≥5%) | 1 123/5 191 (21.6) | 0.65 (0.60, 0.71) |
Intentional‡ | 166/687 (24.2) | 0.77 (0.63, 0.94) |
Unintentional‡ | 175/1 096 (16.0) | 0.44 (0.37, 0.53) |
Weight gain (≥5%) | 1 043/3 725 (28.0) | 0.94 (0.86, 1.02) |
10-Y weight change | ||
Stable weight (within ± 5% change) | 562/1 476 (38.1) | 1.00 |
Weight loss (≥5%) | 342/1 347 (25.4) | 0.51 (0.41, 0.63) |
Weight gain (≥5%) | 174/501 (34.7) | 0.85 (0.64, 1.12) |
*Three-year and 10-year weight change categories significantly differed by survival to age 95 (p < .001).
†Models adjusted for age, study component (Observational Study [OS] or Clinical Trial), race, ethnicity, education, marital status, alcohol, smoking, diet quality, physical activity, physical function, body mass index, coronary heart disease, diabetes, stroke, cancer, emphysema, and hypertension.
‡Intention of weight loss was reported at year 3 among women from the OS component only.
